PredictIt is a U.S.-based political prediction market where participants trade binary outcome contracts on real-world events like elections and policy decisions, using market pricing to reflect collective forecasts and probabilities.

PredictIt’s markets function much like a prediction-oriented financial exchange: each market asks a specific yes/no question (e.g., “Will Candidate X win the nomination?”), and traders buy or sell shares that represent those outcomes. Prices float between $0.01 and $0.99, and they serve as market-implied probabilities of an event occurring — if a share ends up at $0.78, the market consensus suggests a ~78 % chance of that outcome. Because participants can trade shares before resolution, markets generate continuously updated probabilities based on collective sentiment.
For many years PredictIt operated under CFTC no-action letters with conditions like a $850 position limit per contract and a cap on the number of traders per market in order to stay within legal boundaries. A long regulatory and legal battle culminated in PredictIt winning expanded approval from the CFTC in 2025 as a Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO), lifting previous caps (including the 5,000-trader limit) and increasing the per-contract position limit to $3,500 to broaden participation.
PredictIt markets are accessible to U.S. citizens and residents aged 18+ and represent a regulated space for political and public-policy forecasting, blending traditional betting mechanics with market economics. The platform attracts traders interested in both forecasting outcomes and expressing opinions about political futures, and it has been referenced for research and analysis by some media and academic observers as a real-time barometer of public expectations.
In traditional news and polling environments, public sentiment and forecast expectations for political events are often delayed, inconsistent, or biased by sampling methods and reporting. Without a mechanism that aggregates diverse viewpoints and real-time data, it’s difficult for participants — from analysts to voters — to gauge the evolving likelihood of outcomes such as election results, legislative shifts, or major policy decisions.
Trade yes/no contracts whose prices reflect up-to-date implied probabilities for future political and policy outcomes.
Markets operate as a continuous double auction, meaning buy/sell orders interact in real time and prices adjust as conditions and sentiment change.
To meet regulatory criteria, the platform limits how much each individual can invest in a given contract (e.g., up to $3,500) and had caps on participation per market historically.
