Fact checked

Prediction markets have gone from a niche corner of finance to one of the fastest-growing trading categories in the US. After Kalshi’s 2024 court win against the CFTC, regulated event-contract trading expanded into sports, politics, economics, climate and culture — and major brokerages and sportsbook operators have rushed in.(1)

If you’re looking to trade event contracts, the right platform depends on what you want to trade and where you live. Sports markets are restricted by state in many cases. Some platforms specialize in politics and macroeconomics. Others focus on sports parlays. A few are dedicated exchanges; others are integrated into apps you may already use.

Below, we compare the leading regulated prediction market apps in the US, including Kalshi, Polymarket, Robinhood, Moomoo, Crypto.com, Fanatics Markets, and others — their fees, market selection, state availability and who each one is best for.

Prediction market state availability

State-level access to prediction markets — and especially to sports event contracts — varies widely. The legal picture is changing as states, tribal regulators and the CFTC continue to dispute jurisdiction over sports event contracts, so confirm current eligibility on each platform before you sign up.

Below is a snapshot of state availability as of May 2026. Sports event contracts in particular are the subject of ongoing legal disputes between platforms, state gaming regulators and tribal authorities, and access can change with little notice. Always verify current eligibility on each platform’s own site before signing up.

How prediction market fees compare

Fees can meaningfully eat into returns on event contracts, especially on lower-priced trades. The example below shows the approximate fee on a $100 trade buying contracts at $0.50 each (200 contracts). Note that Kalshi’s fees are formula-based and vary by market and contract size; the figure shown is an approximate midpoint.(3)

What are prediction markets?

Prediction markets are platforms where you trade event contracts — simple yes or no positions on the outcome of a future event.

Each contract has a price between $0.01 and $0.99. For example, a contract priced at $0.60 implies a 60% chance the event will occur. If the contract resolves in your favor, you earn $1 per contract; if not, it expires worthless.

This simple structure lets traders speculate on outcomes like elections, economic reports or sports results, while the market price reflects the collective probability of the event occurring.

How event contracts settle: a worked example

Suppose you think the Kansas City Chiefs will win the Super Bowl, and the “Yes” contract for “Chiefs to win Super Bowl LX” is trading at $0.42. The market is implying a 42% chance the Chiefs win.

You buy 100 contracts at $0.42 each, for a total cost of $42 (plus fees).

  • If the Chiefs win, each contract settles at $1. Your 100 contracts pay out $100. Your gross profit is $58 (minus fees) — a return of roughly 138%.
  • If the Chiefs lose, each contract settles at $0. You lose your $42 stake.

You don’t have to wait for settlement. If the Chiefs win their conference championship and the “Yes” contract jumps from $0.42 to $0.75, you can sell early and lock in roughly $33 of profit on your 100 contracts — assuming there’s enough liquidity to fill your sell order.

This continuous pricing is what makes prediction markets behave more like a stock exchange than a sportsbook.

Prediction markets vs. sportsbooks

Prediction markets and traditional sportsbooks both let you wager on outcomes, but they’re structured very differently — and that difference is why prediction markets can operate in states where sports betting is illegal.

  • Sportsbooks set the odds. A sportsbook is the counterparty to your bet. Their odds carry a built-in margin (the “vig”), and the house profits over time on the spread between true probability and the price they offer.
  • Prediction markets are peer-to-peer. Prices are set by supply and demand from other traders. The platform takes a fee but doesn’t take the other side of your trade.
  • Different regulator. Sportsbooks are licensed state-by-state by gaming commissions. Prediction markets are federally regulated by the CFTC, which is why a CFTC-approved platform can offer event contracts nationally — though the legal status of sports event contracts specifically is being challenged in court by states and tribal regulators.
  • Different product framing. Sportsbook bets are gambling. Event contracts are legally classified as derivatives, similar to futures or options. The economic effect can be similar, but the legal and tax treatment differs.

Which prediction market app is right for you?

No single platform is best for everyone — the right pick depends on what you want to trade, where you live, and how you prefer to trade. Here’s a quick guide to which platforms stand out for different use cases, based on our review of each platform’s publicly available information on fees, market selection, state availability and features.

  • If you want the broadest market selection, Kalshi covers the widest range of categories — politics, sports, economics, climate, culture and more — and is the largest US-regulated prediction market by trading volume.(2)
  • If you trade politics or global events, Polymarket has historically had the deepest liquidity in political and geopolitical markets, though US access is still rolling out.
  • If you already use Robinhood, prediction markets sit directly inside the app, with simple per-contract fees and no separate onboarding.
  • If you already use moomoo, event contracts trade inside the app alongside your stocks, options, ETFs and crypto, with no separate onboarding.
  • If you want a prediction market built into a crypto exchange, Gemini Predictions is integrated into Gemini’s existing exchange so you can trade event contracts and crypto from the same account. It launched fee-free in December 2025 but has since transitioned to a standard maker/taker fee schedule.(14)
  • If you’re a sports fan who wants a fan-first interface, Fanatics Markets is built primarily around sports, with a simpler interface than the larger exchanges.

Bottom line

The US prediction market category has expanded fast, with new entrants from Wall Street, Silicon Valley and the major sportsbooks all competing under CFTC oversight. Fees, state availability and market selection vary widely between platforms, and the legal picture for sports event contracts is still being settled in court. Confirm current details on each platform’s own site before opening an account.
