Crypto-Funded vs. Fiat-Only
Most of what's on this page runs on regular dollars - bank transfer, debit card, ACH, nothing different from any brokerage account. The exceptions: Crypto.com Predict and OG.com sit on Crypto.com's own crypto exchange, and Polymarket's global platform is built on USDC. If a bank-account-only setup is a dealbreaker, those three are where to start.
Brand-by-Brand
Our Take on Each Platform
The most markets under one roof. Kalshi covers politics, economics, sports and culture on its own federally regulated exchange - no hopping between apps to find your trade.

The biggest name in the game. Polymarket moves more trading volume than anyone else on this list, and the global platform runs on crypto (USDC) if that's your thing.
Already on Robinhood? You're already set up. No new account, no fresh ID checks - your login routes you to whichever partner exchange (Kalshi, ForecastEx, Rothera, OG.com) has the best price.
Full review coming soon
Cheap trades, crypto-friendly. Fees run as low as a penny a contract, and it lives right inside the Crypto.com app you're probably already using.
Full review coming soon
Feels like your sportsbook, because it basically is. DraftKings brings its familiar parlay-style trading into event contracts, backed by CME Group.
Full review coming soon
Trade sports even where sportsbooks aren't legal. FanDuel Predicts opens sports-adjacent contracts in states without regulated betting, plus financial markets everywhere - all on one flat 2% fee.

Fundamentals
The Fundamentals of Prediction Markets
Prediction markets are similar to sports betting in that you're forecasting the outcome of a real event, but the format is different. You're buying and selling "contracts" tied to that event rather than placing a bet with a bookmaker, and prices range from $0 to $1, reflecting the market's implied probability. You're not going up against a bookie; you're trading against other traders, and market consensus (not a set line) determines what a contract is worth. Funding works like a normal brokerage account at most of these platforms - bank transfer or debit card - though a few, Polymarket's global platform and Crypto.com Predict among them, run on crypto instead of dollars.
Legal Landscape
The Legal Situation Around Prediction Markets
The federal Commodity Futures Trading Commission (CFTC) treats event contracts as a distinct regulatory category from sports betting or online gambling, which is why federally regulated exchanges like Kalshi and ForecastEx can offer sports-adjacent contracts even in states where retail sports betting isn't legal. That distinction is being actively challenged. Several state regulators argue that sports-outcome contracts are simply sports betting by another name, and the fight is playing out in real time.
State AG action
Wisconsin sues Kalshi, Polymarket, Robinhood, Coinbase and Crypto.com
Wisconsin's Attorney General filed suit in Dane County Circuit Court arguing the platforms are facilitating illegal sports betting under the guise of federally regulated event contracts, adding to a growing list of states pushing back on CFTC preemption.

Insider-trading orders
CA, NY and IL bar state employees from trading on inside information
California's governor issued an executive order in March 2026 barring state employees from insider trading on prediction markets; New York and Illinois followed with their own orders in April 2026. Separately, Kalshi suspended and fined two traders in February 2026 for market manipulation and reported the cases to the CFTC.
CA: Mar 2026, NY: Apr 22 2026, IL: Apr 2026
Bottom line for traders: prediction markets currently operate in a genuine gray zone shaped by an ongoing federal-vs-state fight, not a settled legal picture. Which platforms are available, and which contract types they can offer, can change by state and by week.
Where They're Available
Even Where Your State Doesn't Have Legal Online Casinos
One reason prediction markets have taken off so fast: several of them are available nationwide under CFTC oversight, including in states where legal online real-money casino play does not exist yet. If you live somewhere without a regulated online casino market, prediction markets are a legal alternative worth understanding, not a workaround.
Explore What Online Casino Options Are Available in Your State
Legal online real-money casino play is currently limited to a handful of states (PA, MI, WV, NJ). See our full state-by-state casino rundown, or explore no-purchase-necessary social casinos as another option in the meantime.

Liquidity
How much trading activity exists in a market; higher liquidity means fairer, more accurate pricing.

How We Got Here
How Prediction Markets Went Mainstream
2019-2020
Kalshi wins the first federal green light
Kalshi is founded in 2019 and becomes the first CFTC-designated contract market built specifically for event contracts, approved November 4, 2020. It launches to the public in early 2021, establishing the regulatory template every brand on this page now follows.
2024
A presidential election drives mainstream attention
The 2024 US election cycle pushes Kalshi and Polymarket volumes far beyond niche trading circles, introducing millions of Americans to event contracts for the first time and setting up the wave of sportsbook and brokerage entrants that follows.
December 2025
Sportsbooks and brokerages pile in within three weeks
DraftKings Predictions (Dec 19), Fanatics Markets (Dec 3) and FanDuel Predicts (Dec 22, with CME Group) all launch inside the same month, signaling that prediction markets have moved from a niche product to a mainstream one that major sportsbooks see as essential.
March-April 2026
States start drawing insider-trading lines
California's governor bars state employees from insider trading on prediction markets in March 2026; New York and Illinois issue similar executive orders in April, reflecting fast-growing regulatory attention as trading volume scales.
April 2026
Wisconsin sues five platforms over sports contracts
Wisconsin's Attorney General files suit in Dane County Circuit Court against Kalshi, Robinhood, Coinbase, Polymarket and Crypto.com, arguing their sports-related event contracts amount to unlicensed sports betting - the most direct state-level legal challenge yet to the CFTC framework.
June 2026
Sports-first exchanges get their own federal approval
ProphetX and Novig each win CFTC approval to operate as designated contract markets within a week of each other, intensifying competition for sports-focused trading specifically and rounding out the 11-brand field this page compares.

Prediction markets let you trade contracts tied to the outcome of a real-world event, politics, economics, sports, culture, rather than placing a bet with a bookmaker. Contract prices range from $0 to $1 and reflect the market's implied probability of the event happening.
Are prediction markets legal in the US?
Prediction markets are regulated federally by the CFTC as event contracts, a different legal category from sports betting or online gambling. That federal framework is being actively challenged by several states, so availability and contract types can vary by state and can change quickly. See the Legal Landscape section above for the current disputes.
How is a prediction market different from sports betting?
In a prediction market, traders set contract prices through buying and selling, and payouts are fixed between $0 and $1 per contract. In sports betting, a bookmaker sets the odds and payouts vary based on that line. Prediction markets are regulated by the CFTC; sports betting is regulated by state gaming commissions.
Do any of these platforms use or accept crypto?
A few, but most don't. Kalshi, Robinhood, DraftKings, FanDuel, Fanatics, Prophet Exchange, Novig, and ForecastEx all work like a standard brokerage account - bank transfer, debit card, or ACH, dollars in and dollars out. Crypto.com Predict runs on Crypto.com's own CFTC-registered exchange (CDNA), and its 2026 spinoff OG.com shares that lineage. Polymarket's global platform is crypto-native, built on USDC - though the CFTC-regulated product available to US traders runs through a separate clearing arm (Polymarket Clearing/QCEX), so don't assume US deposits work identically to the international platform without checking current funding options.
Can I trade prediction markets in a state without legal online casinos?
Often yes. Several federally regulated platforms on this page operate nationwide because they fall under CFTC oversight rather than state gambling law, which is why they're available even in states with no legal online real-money casino market. Always confirm current availability for your specific state before signing up, since a handful of states are actively contesting this.
Do all 11 platforms compete head-to-head?
No. Kalshi, Polymarket, ProphetX and Novig each run their own exchange. Robinhood Predictions, Interactive Brokers ForecastEx, and (until recently) Fanatics Predictions are brokerage front-ends that route your order to a partner exchange rather than operating one themselves. See the comparison table above for exactly how each brand is structured.
What's the difference between Kalshi and Robinhood Predictions?
Kalshi is its own CFTC-designated exchange with its own order book and market catalog. Robinhood Predictions isn't an exchange at all: it's a feature inside the Robinhood brokerage app that routes your trade to whichever partner exchange, Kalshi, ForecastEx, Rothera, or OG.com, is offering that specific contract. You can end up trading a Kalshi-listed contract through Robinhood without ever opening a Kalshi account.
Do I need a separate account for ForecastEx?
No. ForecastEx is a CFTC-regulated exchange, but it's designed to be accessed through an existing brokerage relationship, either Interactive Brokers directly or, via routing, through Robinhood. You don't create a standalone ForecastEx account or go through separate KYC; you trade its contracts from the brokerage account you already have.
How do I sign up for a prediction market platform?
The process is similar across platforms: create an account, verify your age and identity (18+ on most platforms, 21+ in a few states), deposit funds, and start trading. Brokerage-routed options like Robinhood Predictions and ForecastEx use the KYC you already completed for your existing brokerage account.
What can I actually trade on?
Coverage spans law and politics (election results, court rulings), finance and economics (Fed decisions, company performance, GDP), sports (game outcomes, combo-style contracts), and popular culture (awards shows, major public events). Sports-first platforms like DraftKings, FanDuel Predicts, ProphetX and Novig lean more heavily into game-outcome contracts.
What's the risk with prediction markets?
You can lose your full contract stake if the event resolves against your position, the same fundamental risk as any wagering or trading product. Prices moving against you before settlement (slippage) and low liquidity in thinner markets are the two most common ways a trade goes worse than expected.
