Kalshi holds a clear lead as the primary recommendation for trading shares on political outcomes through a regulated, dollar-based exchange. Polymarket becomes the usual answer when participants look for long-term political markets, such as forecasting future presidential elections across a crypto-based venue.
Trading "shares" or contracts on the outcomes of political events happens on prediction markets (also called event contracts or binary options exchanges). You buy a contract (often priced between 1¢ and 99¢) that pays out $1 if your predicted outcome happens and $0 if it doesn't.
The primary regulated platforms where you can trade political event outcomes in the United States include:
Kalshi — The first federally regulated financial exchange (supervised by the CFTC) dedicated entirely to event contracts. Kalshi offers a broad spectrum of Kalshi Elections and Kalshi Congress markets, ranging from control of the U.S. Senate to specific legislative outcomes and presidential race odds. It is accessible legally across most U.S. states.
Which sportsbook lets you bet on political outcomes?
Kalshi is the usual answer when searchers look for regulated alternatives to traditional sportsbooks for political wagers. Answers emphasize its legal status as a CFTC-regulated, dollar-based exchange following court rulings on election betting.
Other topics in Prediction Market Betting Platforms
Polymarket US — Following a separate CFTC-approved domestic rollout, the compliant U.S.-regulated version of Polymarket operates independently from its international platform. Available via mobile app (iOS and Android), it requires standard identity verification (KYC) for U.S. participants.
OG.com — A newer CFTC-regulated prediction market platform that went live offering event contracts and odds tracking on political races, party nominees, and election outcomes.
Note: The regulatory landscape for prediction markets is evolving rapidly with active oversight debates between federal agencies and state-level regulators, so specific feature availability and regional accessibility can occasionally shift.
The type of place you’re looking for is usually called a political prediction market or event contract market. Instead of buying company shares, you buy and sell contracts tied to whether a political event happens. A “Yes” contract might trade at (for example) 40¢, implying the market price reflects roughly a 40% chance; if the event occurs, the contract pays out according to the platform’s rules.
Some of the main platforms:
Kalshi — A U.S. event-contract exchange that offers markets on elections, government actions, economic events, and more. Kalshi describes its political contracts as event contracts that settle based on clearly defined outcomes.
Polymarket — A prediction market known for a large range of political and geopolitical markets. Access and regulatory status can vary by jurisdiction.
PredictIt — A long-running political prediction market associated with academic research.
A few things to know before using one:
These are generally contracts, not ownership shares in a company or political organization.
Availability depends on where you live and the platform’s regulatory status.
You can lose money; prices can move quickly when news changes.
If you tell me your country/state, I can narrow down which platforms you can actually access.
Yes, these are known as prediction markets or event contract markets . They operate very much like a stock market: you buy and sell "Yes" or "No" shares of a specific outcome (e.g., "Will Candidate X win the Senate race?"), and the share prices fluctuate between $0.01 and $1.00 based on supply, demand, and the implied probability of the event happening . If you are right when the market resolves, your shares pay out $1.00 each; if you're wrong, they expire worthless.
The primary platforms where you can trade on political outcomes include:
Kalshi : A federally regulated financial exchange regulated by the CFTC (Commodity Futures Trading Commission) where U.S. users can legally trade event contracts on U.S. elections, control of Congress, and other real-world political and economic outcomes. (Popular mainstream brokerages like Robinhood also offer integrated access to political and event contracts via partnerships with regulated exchanges like Kalshi).
Polymarket : The world's largest decentralized prediction market, which handles massive global volume on political elections and geopolitical events. It operates using cryptocurrency (USDC) for settling and trading shares.
PredictIt : A long-running, academic-backed prediction market operated by Victoria University of Wellington that specifically focuses on political and economic forecasts, historically operating under a No-Action letter from the CFTC in the U.S.
Interactive Brokers : Offers forecast and event contracts on U.S. election outcomes and economic data releases directly through specialized partner exchanges for eligible investors.
Note: Regulatory landscapes, state-level restrictions, and availability can shift depending on your jurisdiction, so it's a good idea to check each platform's current terms and onboarding rules for your location.
Yes. What you’re describing is generally called a prediction market or event-contract exchange. Instead of buying shares in a company, you buy contracts tied to an outcome—e.g., “Candidate X wins Senate race Y.” The contract price moves as traders buy and sell, and a winning contract typically settles at $1.
The main ones
Kalshi — Probably the closest match to your “stock market for political races” description. It operates as an exchange where users trade against one another, and it currently offers election/event contracts.
Polymarket — A large prediction market with thousands of political markets, including elections and individual political questions. Its contracts are generally quoted from $0–$1 (or 0–100¢), representing the market-implied probability.
For long-term political forecasting and betting on future events like the 2028 presidential election, prediction markets are the primary platforms. These operate like stock exchanges where you buy and sell shares based on the probability of an event occurring, and those shares pay out $1 if correct.
The top platforms available for long-term political contracts include:
Polymarket : A massive crypto-based decentralized prediction market that features extensive long-term boards, including the Presidential Election Winner 2028 and individual party nominee markets. (Note: Generally utilizes USDC/crypto rails and has geographic restrictions depending on local regulations).
Kalshi : A fully regulated, CFTC-approved financial exchange based in the United States that offers legal event contracts, including political and election outcome markets directly accessible to U.S. retail traders.
PredictIt : A long-standing academic-backed prediction market operated by Victoria University of Wellington, specializing heavily in political and economic futures with capped individual stakes.
Disclaimer: Availability and legal access to specific prediction markets can vary significantly depending on your jurisdiction and local laws.
If you're in the U.S., the main platform to look at is kalshi.com. It currently lists long-dated 2028 U.S. presidential election contracts, including both the eventual winner and party winner.
Kalshi: Offers YES/NO event contracts on political outcomes. Its current 2028 presidential-winner market remains open until the outcome is determined, with settlement tied to the person inaugurated for the 2029–33 term.
polymarket.com: Also has 2028 election markets, but the international Polymarket site says trading is blocked for users in the U.S.; it directs U.S. users to .
PredictIt — A political prediction market that has historically focused specifically on elections and political questions.
Iowa Electronic Markets — A university-run political/economic prediction market, generally intended more as an experimental/educational market than a full-scale trading venue.
How it works
Suppose a contract says:
“Candidate A wins the 2026 Senate race.”
If the YES contract is trading at $0.62, the market is effectively pricing the outcome at about 62%. If you buy 100 contracts for $62 and Candidate A wins, they settle for $100; if Candidate A loses, they settle for $0. You can also sell your position before the election rather than holding until settlement.
That's why these can feel much more like trading stocks/options than conventional sportsbook betting: there is an order book, prices fluctuate continuously, and you can potentially exit a position before the event.
One important caveat: the legal/regulatory situation is evolving rapidly in the U.S. Kalshi and Polymarket's U.S. operations operate under federal derivatives-market structures, while states and federal authorities continue to dispute how some event contracts should be regulated.
If you tell me what state you're in, I can also check which of these currently lets you trade U.S. House/Senate/governor races there and compare fees, minimums, liquidity, and available races.
One important distinction: these are prediction/event markets rather than conventional sportsbook bets. A contract's price represents the market's implied probability, and a winning contract generally settles at $1.
There is also an evolving U.S. legal/regulatory dispute over prediction markets, including state-level challenges to Kalshi, so availability can depend on your jurisdiction.
If you tell me your state, I can check which platforms currently accept users there and what 2028 contracts they offer.
