Polymarket is the world's largest decentralized prediction market, operating on Polygon for fast, low-cost trades. Accessible globally (except in much of the US, where limited access began relaunching in Dec 2025 via a CFTC-approved partner), users trade yes/no contracts on everything from politics and crypto to sports and science using USDC. Over $18B volume in 2024-2025 attests to its dominance. Polymarket is non-custodial: all trades are on-chain and outcomes are resolved through decentralized oracles. US access remains limited/waitlisted as of late 2025.
Pros

- +Thousands of markets in politics, crypto, sports, etc.

Kalshi is the first CFTC-approved event contract exchange in the US, letting users trade yes/no contracts in USD on economic, financial, and select sports outcomes.

Prediction markets are speculative markets created for the purpose of making predictions. The current market prices can then be interpreted as predictions of the probability of the event or the expected value of the parameter. For example, a contract that pays $1 if a specific candidate wins an election, and currently trades at $0.60, implies a 60% probability of that candidate winning according to the market consensus.
Unlike traditional financial markets which trade assets like stocks or commodities, prediction markets trade information. They harness the "wisdom of crowds," where the aggregated belief of many participants is often more accurate than individual experts. This mechanism allows participants to hedge against risks (e.g., a farmer hedging against poor weather) or simply profit from their foresight regarding future events.
These markets have grown significantly with the advent of blockchain technology, which allows for trustless, global participation. However, regulated entities also exist, providing a safer, albeit sometimes more limited, environment for traders. The core value proposition remains the same: putting a price on the future.
