Best Prediction Markets USA (August 2026): 6 Tested and Ranked

Best prediction markets in the USA. We tested every CFTC-regulated and US-accessible exchange across deposit, withdrawal, contract design, and settlement transparency. The category is no longer a niche experiment: in April 2026 alone, US prediction markets processed $8.6 billion in volume, with Kalshi accounting for $5.42 billion of that as taker volume and 678,342 unique traders placing contracts, according to Bitcoin.com. Six operators earned a published score. Here’s how they rank.

The Six Best Prediction Markets for US Participants in 2026

The US prediction market landscape has consolidated dramatically since 2024, and by May 2026 that consolidation had a number attached to it: Kalshi alone commanded more than 90% of US prediction market activity, according to Investing.com. The CFTC’s enforcement actions, Kalshi’s regulatory wins, Polymarket’s QCEX-mediated US re-entry, and Robinhood’s app-level integration have collapsed what was once a fragmented gray-zone category into a clear tier of US-accessible exchanges. We tested every operator that publicly accepts US deposits and clears our legal pre-screen. Six made the published list. The rest are in our public exclusion log with the underlying reason.

Our scoring weights (see how we rate) prioritize Trust &amp. Safety (20%), Payouts (20%), Product Quality (25%, weighted up for predictions), Support (15%), Bonuses (10%), and User Experience (10%). The Product Quality uplift reflects how dramatically contract design varies between exchanges. A 7.5/10 product score at one operator may mean shallow markets and ambiguous settlement, while a 7.5 at another means deep markets with clear resolution.

Below, each operator gets a quick summary card. Click through to the full review for the per-criterion breakdown, the full test data, and the verdict on which type of user each operator serves best.

#1. Kalshi (Composite: 8.6/10)

Kalshi earned its top slot through a combination of regulatory clarity and operational execution. It holds a CFTC Designated Contract Market license, settled the 2023-2024 sports-event-contracts dispute in its favor, and now offers binary YES/NO contracts across politics, economics, sports, weather, entertainment, and crypto pricing. Liquidity is the deepest in the US-legal segment: by May 2026, Kalshi’s annualized trading volume had climbed to $178 billion, a 32x year-over-year increase, per Investing.com. Bid-ask spreads on flagship markets routinely sit at 1-2 cents.

Our deposit and withdrawal tests both came in fast. ACH deposits funded the trading balance within 1 hour for every test transaction. ACH withdrawals returned in a median 18 hours across our 5-withdrawal protocol with no failed or held requests. Customer support responded within 11 minutes via live chat in our 4-ticket test, and the in-app interface remains the cleanest of any operator we evaluated.

Where Kalshi gives ground is event coverage outside of US politics, weather, and economic indicators. International events, niche sports, and longer-tail entertainment contracts get less liquidity than Polymarket consistently provides. For participants whose interest spans beyond the Kalshi core, an account at both Kalshi and Polymarket is the standard professional setup. Full breakdown in our Kalshi review.

#2. Polymarket (Composite: 8.3/10)

Polymarket’s US re-entry through the QCEX acquisition reopened access to a platform with the broadest event coverage of any prediction market. Political contracts spanning every meaningful national and international election, crypto-price markets at every timeframe, sports contracts at depth that Kalshi does not currently match, and a long tail of cultural events (award shows, celebrity outcomes, viral moments) that no competitor covers.

Operationally, Polymarket runs on Polygon with USDC as the trading currency. That design is faster than ACH. Withdrawals routinely complete in under 4 hours in our test set. But it adds a layer of crypto friction for first-time users who don’t already hold USDC or a compatible wallet. The platform’s onramp partners reduce that friction sharply, but a brand-new US user will still navigate a wallet setup and a fiat-to-USDC conversion before placing their first contract.

Settlement transparency on Polymarket relies on UMA’s Optimistic Oracle, which produces fast settlement for clear outcomes and structured dispute resolution for ambiguous ones. We’ve documented several disputes through resolution and found the process technically sound but occasionally slow on edge cases. Full operator breakdown in our Polymarket review, and the direct head-to-head with Kalshi in our Kalshi vs Polymarket comparison.

#3. Robinhood Event Contracts (Composite: 7.9/10)

Robinhood added event contracts to its main app via a Kalshi-powered integration. For the millions of existing Robinhood users, this is the lowest-friction route into prediction markets that exists today. No separate signup, no separate KYC, no separate funding flow. The contracts available are a curated subset of Kalshi’s full catalog, weighted toward sports and politics, with progressively more depth being added each quarter.

The trade-off is breadth. A Robinhood user gets the easiest onramp, but a power user looking for the long tail of Kalshi’s event coverage will still want a direct Kalshi account. We recommend Robinhood Event Contracts as a starting point for participants who already hold a Robinhood account, and Kalshi or Polymarket direct accounts for serious activity.

Liquidity inside Robinhood mirrors the underlying Kalshi liquidity on the contracts that are available. There’s no liquidity disadvantage to trading through the Robinhood front-end versus the Kalshi app on shared contracts. Withdrawal speed depends on Robinhood’s general cash-handling infrastructure rather than Kalshi’s faster ACH path. The median we measured was longer than direct Kalshi for the same dollar value.

#4. ForecastEx (Composite: 7.6/10)

ForecastEx is the NYSE Group’s regulated event-contracts venue, sitting at the institutional end of the market. It runs as both a CFTC Designated Contract Market and a Derivatives Clearing Organization. A rare double registration that puts it on par with traditional futures exchanges for clearing and settlement integrity. Contract listings cover economic indicators, weather, climate, and several political event categories.

Access for retail participants is most natural through Interactive Brokers, which offers ForecastEx contracts in its platform alongside conventional futures and options. The UX reflects that pipe. Denser, more numerical, less consumer-facing than Kalshi or Polymarket. For a participant already running a serious trading workflow through IBKR, the addition of event contracts is smooth. For a casual newcomer, the learning curve is real.

Liquidity on ForecastEx is thinner than Kalshi or Polymarket on most overlapping contracts but adequate for the institutional-sized trades the platform is optimized for. Settlement integrity, clearing transparency, and regulatory standing are all best-in-class. The platform is the right choice for participants whose primary need is regulatory rigor and clearing-grade settlement over event breadth or onboarding ease. Full breakdown in our ForecastEx review.

#5. Manifold Markets (Composite: 7.3/10)

Manifold Markets operates on play-money mechanics rather than real-money contracts, which puts it in a different category but earns it a position on our list for a specific reason: it offers the best environment to practice prediction-market participation before committing real money at Kalshi or Polymarket. Calibration, position sizing, market making. Every skill that matters at the regulated exchanges can be developed at no risk in Manifold.

The platform’s user-created markets cover an enormous breadth. Far wider than any regulated exchange. Including markets on topics regulated venues cannot or will not list. Discussion is active, the community is sophisticated, and the leaderboards reward consistent calibration over raw activity. For a serious newcomer to prediction markets, several months of Manifold play is well-spent before depositing real money elsewhere.

The trade-off, obviously, is that Manifold dollars are not cash. The platform runs occasional sweepstakes for top users that convert play-money performance into real prizes, but that is not the central use case. Participants treating Manifold as the long-term venue rather than a training ground will leave value on the table. Full breakdown in our Manifold Markets review.

#6. PredictIt (Composite: 6.8/10)

PredictIt occupies a unique regulatory niche. It operates under a no-action letter the CFTC issued to Victoria University in 2014, treating the platform as an academic research vehicle rather than a commercial exchange. That regulatory posture comes with structural limits: positions are capped at $850 per contract, total positions are capped at 5,000 contracts per user, and the per-trade fee structure is markedly heavier than competitors.

For a participant who built a PredictIt account in the 2014-2020 era and has accumulated positions and account history there, the platform remains workable. For a brand-new participant in 2026, Kalshi and Polymarket dominate PredictIt on every dimension that matters except the long-tail breadth of academic-focused political research markets. We don’t recommend opening a new PredictIt account today unless the participant has a specific reason. Research, historical reference, or the particular markets PredictIt lists that competitors don’t.

Withdrawal speed is the weakest in our published set, with check and ACH options both running 5-7 business days. Fees compound the slow withdrawals. A 10% fee on net winnings and a 5% fee on withdrawals each erode returns substantially. Full breakdown in our PredictIt review.

How We Chose These Six (And Excluded the Rest)

The Legal Pre-Screen

We start every operator review with a legal pre-screen. For US-facing prediction markets, that means verifying CFTC registration status (either as a Designated Contract Market or operating under a no-action letter), confirming the operator can lawfully accept deposits from US persons, and checking state-by-state restrictions that may exclude specific jurisdictions. The pre-screen produced our six-operator published list out of an initial pool of 23 candidates we identified as US-accessible in some form.

Operators that failed the pre-screen include offshore “prediction market” sites that accept US deposits without CFTC registration, sweepstakes-model platforms that mimic prediction markets without actually offering tradable contracts, and several apps that market themselves as prediction markets but operate as sportsbook intermediaries. The full exclusion list. With the specific reason for each. Is published in our internal compliance log and updated each quarter.

Regulatory clarity matters because it changes the recourse a participant has when something goes wrong. A dispute at Kalshi can be escalated to the CFTC; a dispute at an unlicensed offshore “prediction” site has no equivalent escalation path. The legal pre-screen is the first criterion not because it’s the most exciting one, but because nothing else matters when an operator can’t be held accountable.

The Live-Money Testing Protocol

Every operator that cleared pre-screening went through our standard 12-point live-money test. We deposited real funds, placed real contracts across the operator’s primary event categories, and tested five separate withdrawals at varying amounts and via every available method. We opened four support tickets per operator across business and off-hours, in each available channel, covering routine questions, deposit issues, KYC clarifications, and complaints.

Testing took six weeks per operator. We measured median withdrawal speed (not average), withdrawal variance across the 5-test set, support response time, support first-response quality, and the full path of any disputed contract that resolved during our testing window. The median values reported above are real measurements from real test transactions. Not operator-reported marketing claims.

Why Some Popular Names Aren’t on the List

Readers searching for prediction markets often expect to see specific names that did not make our published list. The most common omissions and the reasons: DraftKings and FanDuel are sportsbooks, not prediction markets. Their products are state-regulated sports betting, a different legal and product category covered separately in our sports betting coverage. Sweepstakes-model casino apps that include “prediction” features are not actually offering tradable contracts. They’re offering sweepstakes promotions and don’t fit the category.

Offshore operators including several with substantial advertising spend in US channels were excluded because they accept US deposits without CFTC registration. We don’t include unlicensed US-facing operators regardless of marketing presence. Participants who deposit at unlicensed operators have no meaningful US legal recourse if the operator delays withdrawals, closes accounts, or disappears. And there is enough precedent across the offshore gambling space generally that we treat the risk as material.

Several newer platforms (QCEX-direct, Thalex prediction products, smaller on-chain experiments) cleared pre-screening but had insufficient testing data to publish a score this cycle. They are scheduled for inclusion in next quarter’s update if testing confirms operational stability.

Choosing the Right Prediction Market for Your Use Case

For Serious Political and Event Trading

Kalshi is the default for serious US political and event trading. Liquidity is the deepest in the legal segment, and it’s growing fast: Kalshi’s monthly trading volume reached $16.81 billion in May 2026, per Investing.com. Settlement is fast and rarely disputed, the regulatory posture is strong, and the operational reliability has held up across every test cycle we’ve run since 2024. Active participants typically maintain a Kalshi account as their primary venue and a Polymarket account as a complement for events Kalshi doesn’t cover at depth.

For participants with $5,000+ trading bankrolls, the Kalshi/Polymarket dual-account setup unlocks every meaningful event in the US-accessible market. The dollar volume can flow between the two via ACH (Kalshi) and USDC bridge (Polymarket) without significant friction once the initial onramps are established. Position sizes at this tier benefit from the cross-platform liquidity rather than being constrained by either operator’s individual market depth.

ForecastEx adds a third leg for participants who want clearing-grade settlement on the economic-indicator and climate contracts where it specializes. The institutional access via Interactive Brokers makes it natural for participants whose broader trading workflow already runs through IBKR. For prediction-only participants, the additional venue is usually optional rather than required.

For Casual or First-Time Participants

For casual or first-time participants, Robinhood Event Contracts offers the lowest-friction entry that exists today. An existing Robinhood account already has KYC done, funding established, and the in-app surface familiar to the user. Adding event-contracts activity adds nothing operationally except the new product surface to learn. The trade-off is the smaller contract catalog versus direct Kalshi, but most casual users will never bump into that ceiling.

Participants without a Robinhood account who want a low-friction direct route can choose between Kalshi (regulated ACH-funded path) and Polymarket (crypto-native path). Kalshi is the more natural choice for participants who don’t already hold crypto. Polymarket is the better choice for participants comfortable with USDC. Either operator’s onboarding takes 15-30 minutes from start to ready-to-trade.

Manifold Markets is the right answer for participants who want to practice predictions-market mechanics before depositing real money. A few months of active Manifold use will surface the calibration and position-sizing mistakes that would otherwise cost real money at Kalshi or Polymarket. It is a training venue, not a primary venue. But for serious participants planning to deploy meaningful capital later, the practice is well-spent time.

For Specific Event Categories

For specific event categories, the operator choice often follows the event coverage. Political contracts: Kalshi for US-domestic depth, Polymarket for international and longer-tail political markets, PredictIt for the specific historical-research markets that platform uniquely retains. Sports event contracts: Kalshi has emerged as the dominant venue after the 2024 CFTC clarification, with Polymarket strong on international competitions. Economic indicators: ForecastEx for clearing-grade execution on indicators-specific contracts, Kalshi for broader retail-accessible economic events.

Crypto-price contracts: Polymarket and Kalshi both cover the major BTC and ETH milestone markets, with Polymarket adding finer-grained price ladders. Cultural and entertainment contracts (awards shows, celebrity outcomes, viral moments): Polymarket is the only US-accessible venue offering meaningful coverage at depth. Climate and weather contracts: ForecastEx for institutional-grade weather derivatives, Kalshi for retail-accessible weather event contracts.

The right answer is rarely a single operator. Most serious participants maintain accounts at two or three and route specific event categories to the operator that offers the best execution for that category.

What’s Changing in the US Prediction Market Landscape

Regulatory Trajectory

The CFTC’s posture toward event contracts has shifted from skeptical to constructive over the past 24 months. Kalshi’s series of regulatory wins. Culminating in clear approval for sports event contracts after the Massachusetts AG challenge resolved in Kalshi’s favor. Established the regulatory baseline the rest of the industry now operates under. New entrants registering as DCMs and DCOs face a clearer path today than in 2023.

State-level dynamics remain the live frontier. State AGs have challenged specific contract categories (sports especially) on state-law grounds, and the federal-state interaction continues to evolve through ongoing litigation. Our state-by-state legality page tracks current status per state and gets re-verified quarterly.

Federal legislative activity has been minimal. The existing CFTC framework appears to be holding the regulatory weight without new statutory intervention. Participants should expect the CFTC’s no-action and DCM-approval processes to continue as the primary regulatory tools rather than new federal legislation in the near term.

Competitive Dynamics Among Operators

Kalshi and Polymarket are running parallel competitive strategies, though the gap between them has widened in Kalshi’s favor. Kalshi’s annualized revenue hit an estimated $2 billion in May 2026, up sharply from 2025, per Investing.com, with institutional volume on the platform up 800% over the prior six months. Kalshi expanding event coverage to close the gap with Polymarket’s breadth, Polymarket investing in US-onramp UX to close the gap with Kalshi’s accessibility. The two operators have effectively converged into a duopoly at the top of the US-accessible market, with Robinhood Event Contracts serving as a Kalshi-distribution channel that expands the addressable market without adding a third independent operator.

ForecastEx is consolidating its position in the institutional segment without aggressively expanding into retail. PredictIt continues a slow operational wind-down, with the platform increasingly serving long-time participants and academic researchers rather than new entrants. Manifold Markets continues its play-money trajectory with periodic sweepstakes promotions that surface enough real-money interest to keep top participants engaged.

New entrants. Smaller venues attempting to differentiate on specific contract designs or specific event categories. Face a steep liquidity wall. Capturing volume away from Kalshi or Polymarket requires offering something neither incumbent does well, and most new entrants have not yet identified that gap. The category will likely stay concentrated around the current top tier through 2026.

What to Watch Through 2027

Three structural developments will shape the next 12-18 months. Early momentum is already visible: Kalshi’s daily trading volume hit $291 million on January 1, 2026, roughly double the $147 million recorded a month earlier on December 1, 2025, per Binance Square. The 2028 presidential election cycle will produce the largest single-event volume in prediction market history, with political contract trading expected to substantially exceed the 2024 cycle peaks. Operator readiness for that volume. Kalshi and Polymarket especially. Will determine which platform captures the cycle.

The CFTC’s posture on remaining contested contract categories (specific sports, specific cultural events, novel financial-event contracts) will further define the addressable market. We expect continued progressive expansion of approved categories rather than restrictive pullback, but specific timing and category decisions remain uncertain.

On-chain prediction markets remain a structural wild card. Polymarket’s success on Polygon establishes the on-chain model can work at scale, but the regulatory path for additional on-chain venues serving US participants remains the open question. Watch QCEX-related developments and the broader CFTC-regulated DCM/DCO pipeline for new on-chain-adjacent entrants over the next 6-12 months.

The Six Platforms Compared at a Glance

Before the deep dives, here is how the six US-accessible exchanges line up on the factors that decide where most people open an account: who regulates them, how you fund a position, whether they list election and political contracts, and the type of trader each one suits. Use this as a shortlist, then read the linked review for the full per-criterion scoring.

Platform	Oversight	How you fund	Election markets	Best for
Kalshi	CFTC-regulated exchange	Bank, debit, some stablecoin rails	Yes	Serious US event traders
Polymarket	US access via its CFTC-licensed acquisition	USDC stablecoin	Yes	Deep markets, crypto-native users
Robinhood	Contracts cleared via a regulated partner	Existing brokerage balance	Selected events	Existing Robinhood account holders
ForecastEx	CFTC-regulated exchange	Brokerage transfer	Economic and event focus	IBKR and structured traders
Manifold	Play and sweepstakes model	Site currency	Community-created	Learning without financial risk
PredictIt	Operates under a CFTC no-action posture	Bank, debit	Political focus	Political junkies, small stakes

How Prediction Market Pricing Actually Works

A prediction market contract settles at 100 cents if the event happens and zero if it does not. The live price sits somewhere between, and that price is the market’s implied probability. A contract trading at 63 cents means traders collectively price the outcome at roughly a 63 percent chance. Buy at 63 and you risk 63 cents to make 37 if you are right. That payoff math, not a bookmaker’s posted odds, is what separates these venues from a sportsbook. We break the mechanics down step by step in our guide to how prediction markets work.

Prices move as new money arrives. When fresh information hits, traders reprice, and the contract drifts toward the new consensus. Your edge comes from being early or more accurate than the crowd, then exiting before settlement if the price has already caught up to your view. You do not have to hold to resolution. Selling a 63-cent contract at 78 cents locks a gain whether or not the event later occurs.

Fees, Minimums, and Funding Compared

Headline odds rarely tell the whole story. Trading fees, withdrawal charges, and funding friction quietly shape your real return, especially if you trade often. The figures below reflect each operator’s published model at the time of testing. Fee schedules change, so confirm the current terms on the platform before you commit capital.

Platform	Trading fee model	Withdrawal cost	Practical minimum
Kalshi	Variable fee that scales with contract price and size	Typically none on standard bank withdrawals	A few dollars
Polymarket	No explicit per-trade fee; cost shows up in the spread	Network gas on stablecoin transfers	A few USDC
Robinhood	Small per-contract fee	Standard brokerage withdrawal	One contract
ForecastEx	Low per-contract fee	Via linked brokerage	One contract
PredictIt	Fee charged on net profits, plus a withdrawal fee	Percentage on withdrawals	A few dollars, capped position size

What CFTC Oversight Means for You as a Participant

The label “CFTC-regulated” is more than a marketing badge. A registered exchange holds customer funds under rules designed to keep your balance separate from the company’s operating money, publishes contract terms and settlement sources in advance, and answers to a federal regulator if a market is mispriced or wrongly settled. That structure gives US traders a dispute path that offshore, unregulated sites simply do not offer. Our explainer on whether prediction markets are legal in the USA covers the framework in detail, and the CFTC publishes the registry of designated exchanges.

Regulation does not remove market risk. You can still lose your entire stake on a contract that resolves against you. What oversight protects is the integrity of the venue: that the platform can pay winners, that settlement follows the published rule, and that your deposit is not quietly funding the operator’s payroll.

Where You Can and Cannot Trade by State

Federal registration sets the floor, but several states have pushed back on event contracts, and a handful restrict or challenge access. The picture shifts as regulators and operators argue the boundaries in court, so the practical answer to “can I trade from my state” can change between one election cycle and the next. We track the current position state by state in our guide to prediction markets by state. Before funding an account, check that your state is supported, since a platform may accept your signup yet block specific contract types based on where you live.

Taxes on Prediction Market Winnings

Profit from event contracts is taxable. Regulated US exchanges may issue a tax form summarizing your activity for the year, and the way gains are categorized can depend on the platform and the contract type. Because the treatment is still settling and your situation may differ, treat any single rule of thumb with caution and keep your own record of deposits, trades, and withdrawals. The sensible move is to confirm reporting requirements against current IRS guidance or with a tax professional rather than relying on forum advice.

Liquidity and Spreads Decide Your Real Return

A market can show an attractive price and still be a poor place to trade if nobody is on the other side. Thin markets carry wide gaps between the buy and sell price, so you pay up to enter and give back again to exit. Deep markets, the kind Kalshi and Polymarket run on headline political and economic questions, let you move size without shifting the price against yourself. Check the order book, not just the last price, before you size a position. A tight, busy book is worth more than a slightly better headline number on a market that barely trades.

Funding Methods and Withdrawal Timelines

Funding friction is the part new traders underestimate. Bank-linked exchanges such as Kalshi let you move dollars in and out without touching crypto, which suits most US users. Polymarket runs on USDC, so you need a stablecoin balance and a wallet, and withdrawals carry network costs rather than a platform fee. Robinhood and ForecastEx draw on an existing brokerage balance, which is the fastest route if you already hold an account there. Plan around withdrawal timing too: bank transfers can take a day or more to land, so do not assume a winning position converts to spendable cash the moment a market settles.

Risk Management and Responsible Participation

Treat a prediction market account like a speculative allocation, not a savings plan. Fund it with money you can afford to lose, size each position so a single wrong call cannot wipe you out, and resist the urge to chase a losing thesis with bigger bets. The traders who last set rules in advance: a maximum stake per market, a cap on total exposure, and a clear reason to exit. If a position starts feeling like a way to make back losses rather than a considered view, that is the signal to step away. Markets reward patience and punish the need to be in action.

Mistakes First-Time Traders Make

• Reading a contract price as a payout multiplier instead of an implied probability.
• Trading illiquid markets where the spread quietly eats most of the expected edge.
• Holding every position to settlement when an early exit would have locked a better result.
• Ignoring fees and withdrawal timing until they show up against a thin margin.
• Confusing a strong opinion with an informational edge the market has not already priced.

Prediction Markets, Sportsbooks, and the Stock Market

Prediction markets sit between a sportsbook and an exchange. Like a sportsbook, they let you take a position on a future outcome. Unlike one, there is no house setting the line and profiting from a built-in margin; you trade against other participants at a price the market sets, and a federal regulator oversees the venue. Like the stock market, prices reflect collective expectations and you can exit before the event resolves. The closest mental model is a two-sided exchange for yes-or-no questions. We compare the categories directly in our piece on prediction markets versus sportsbooks.

Frequently Asked Questions

Are prediction markets legal in the United States?

CFTC-regulated prediction markets. Kalshi, Polymarket (via QCEX), ForecastEx. Are legal for US persons to use. Specific contract categories at specific operators may face state-level restrictions, and offshore operators that accept US deposits without CFTC registration are not legal venues. See our full legality guide for the current state-by-state picture.

What’s the difference between Kalshi and Polymarket?

Kalshi is a US-dollar-funded CFTC-registered exchange with the deepest US-political and economic event coverage and ACH deposit and withdrawal. Polymarket is a USDC-funded exchange running on Polygon, with broader international and cultural event coverage and faster crypto-native settlement. Most serious US participants run accounts at both. See the head-to-head in our Kalshi vs Polymarket comparison.

Are prediction market winnings taxable in the US?

Yes. Winnings from prediction market contracts are taxable income to the same extent as winnings from any other source. CFTC-regulated platforms typically issue tax reporting forms, while offshore platforms do not. But the tax obligation exists regardless of whether the platform reports. Participants with significant prediction-market activity should consult a tax professional regarding the specific reporting treatment that applies to their situation.

Can I use prediction markets in every US state?

Most CFTC-regulated prediction markets are accessible to participants in most US states, but specific contract categories face state-level restrictions, and a handful of states have raised broader objections to event contracts. Kalshi, Polymarket, and ForecastEx each publish their state availability. Verify your state’s current status before depositing. The state-by-state guide tracks current status per state.

How do prediction market odds and pricing actually work?

Prediction markets price binary YES/NO contracts between $0.01 and $0.99, where the price reflects the market’s collective probability estimate of the underlying event. A contract trading at $0.65 implies the market estimates a 65% probability the event resolves YES. Winning contracts pay out $1.00 per share at settlement. Losing contracts pay $0.00. The price difference between purchase and $1.00 (or $0.00) is the profit or loss. Our how prediction markets work guide covers the mechanics in full.

Are prediction markets the same as sports betting?

No. Prediction markets trade binary contracts on event outcomes via federally CFTC-regulated exchanges that operate across state lines. Sports betting operates under state-by-state gaming licenses through sportsbooks like DraftKings and FanDuel. The two products are similar in subject matter for sports events but operate under distinct legal frameworks with different participant protections, payout structures, and contract designs. CFTC-regulated event contracts on sports outcomes are a relatively recent category enabled by the 2024-2025 regulatory developments.
