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.

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.
