What Is Polymarket?

Polymarket is a prediction market platform where you can trade on the outcomes of real-world events. Founded in 2020, it has become the world's largest prediction market by volume, processing over $10 billion in cumulative trades.

You buy shares in outcomes (Yes or No) priced between 1 cent and 99 cents. The price reflects the crowd's probability estimate. When the event resolves, winning shares pay $1.00 and losing shares pay $0. Your profit is the difference between what you paid and the $1.00 payout.

Polymarket gained massive mainstream attention during the 2024 US presidential election, when it became the go-to platform for real-time election odds. Media outlets from CNN to The New York Times cited Polymarket probabilities alongside traditional polls.

The Bottom Line

Polymarket is the clear leader in prediction markets for 2026. It offers the lowest fees, deepest liquidity, and widest market selection. The CFTC approval in 2025 addressed the biggest concern — regulatory legitimacy — making it a viable platform for US traders.

The main drawbacks are the crypto learning curve and lack of tax reporting. If you're comfortable with USDC and willing to self-report your taxes, Polymarket is the best platform for serious prediction market trading.

If you want something simpler with USD deposits and tax forms, Kalshi is the better choice — just expect higher fees and less liquidity.
