A plain guide to politics and election prediction markets: what you can trade, how a contract settles against official results, the legal story behind United States election contracts, the real risks, and the questions to ask first. Information, not advice.

Most markets here are binary: a clearly defined yes or no question. Each contract resolves to one dollar if yes and zero if no. The price you pay between 1 and 99 cents is the market's live read on the odds.
Settlement follows a written rule defined before trading: the named source, the date, and how edge cases are handled. Read that rule before you trade; it is the contract.
Resolution sources and timing differ by platform and market. Always check the specific market's rules, not the headline.
Drag to see how a contract price maps to an implied chance, and what 100 dollars would return if it resolves yes.
A price is the market's estimate of probability, not a forecast of the result and not advice. Fees and spreads reduce real returns. Illustrative; excludes fees.
Structures differ. Some charge a per-contract fee, others earn on the spread. Compare like with like. As of June 2026; illustrative.
If you cannot answer these for a specific market, you do not yet understand what you would be buying.
What exact source and date decides this market, and who adjudicates a dispute?
Is there enough liquidity for me to exit at a fair price before resolution?
What are the all-in costs, fee, spread, deposit and withdrawal, on a trade this size?
Is this platform legally available to me, and am I within its age and verification rules?
What is the most I am willing to lose here, and have I decided that before buying?
A political prediction market is a market in binary contracts on a defined political outcome, such as which party wins control of a chamber, who wins an election, or whether a named candidate secures a nomination. Each contract settles at one dollar if the outcome happens and zero if it does not, and the price between one cent and ninety nine cents reads as the implied probability. This is general information, not advice.
It settles against the resolution source named in the contract rules, usually official results or a defined authoritative source once an outcome is final. The contract rules state the exact source, the timing, and how edge cases such as recounts or disputed results are handled, so read them before trading.
On federally overseen venues, election event contracts went live in late 2024 after a federal court allowed a registered exchange to list them and an appeals court declined to block it, and the Commodity Futures Trading Commission later dropped its appeal in 2025. The status remains contested at the state level, with at least one state bringing charges that include election wagering counts. This is general information, not legal advice, current as of June 2026.
Yes. A market price is an implied probability, not a forecast of certainty, and political markets have been confidently wrong before. Prices can also move sharply on news, polling, or a single large trade, so they carry real risk of loss.
On most venues you can sell your position back into the market at the current price before the event resolves, subject to enough liquidity, or hold to settlement where a correct contract pays one dollar and an incorrect one pays nothing.
