Best Prediction Markets for Elections in 2026
Election prediction markets exploded after 2024. Here are the platforms with the deepest political order books, the cleanest contract design, and the regulatory clarity to actually use them.
Top picks for election contracts
#1 pick
Kalshi
Deepest US politics liquidity, CFTC-regulated, accepts US residents directly.
#2 pick
Polymarket
Best for non-US elections. EU, UK, Brazil, India, and global pop politics.
#3 pick
PredictIt
Academic-research market with a loyal political-junkie community. Position caps limit pros.
Kalshi: the US politics leader
Kalshi runs the deepest order books on US elections, from presidential contests to individual House and Senate races. Because it is CFTC-regulated, US residents can fund accounts with a US bank and trade contracts that settle in dollars. The 2024 cycle moved the equivalent of hundreds of millions of dollars on Kalshi political contracts alone, and 2026 midterm volume is already on pace to surpass it.
Kalshi also lists derivative political contracts most platforms ignore: cabinet nominee confirmations, presidential approval crossing specific thresholds, government shutdown probabilities, even Federal Reserve chair appointments. For a US-resident trader who wants to express a political view through a regulated market, there is no closer match.
Polymarket: global elections at depth
Polymarket dominates global election contracts. EU parliament outcomes, UK general elections, Brazilian and Indian polls, and the rolling drama of cabinet shake-ups in dozens of countries all see real liquidity here. Volume often exceeds Kalshi on non-US events because Polymarket’s user base is genuinely global.
The platform settles in USDC on Polygon, so funding requires comfort with crypto wallets. US residents are geo-blocked. For European, Asian, and Latin American traders, Polymarket is usually the first stop for any major election.
PredictIt: the academic legacy market
PredictIt operates under a CFTC no-action letter as a research project of Victoria University. Position caps of $850 per contract limit how seriously professional traders can use it, but the platform retains a passionate community of US political junkies. Liquidity has thinned since Kalshi entered the regulated market, but PredictIt remains useful for niche state-level contracts that bigger platforms ignore.

How election contracts work
An election contract is a binary yes or no question about a specific outcome, like “Will candidate X win the 2026 Senate race in Pennsylvania?” Each contract trades between $0.01 and $0.99. The price is the market’s implied probability. If the answer ends up yes, the contract settles at $1.00. If no, it settles at $0.00.
You can buy yes or sell no (effectively the same trade). You can close the position before settlement by selling into the order book at the current market price. Unlike sportsbook bets, prediction market contracts have a continuous secondary market. You are not locked in until the event resolves.
Frequently asked questions
Are election prediction markets legal in the US?
Kalshi is the only platform with full CFTC-regulated status to offer election contracts to US residents. PredictIt operates under a separate CFTC no-action letter with strict position caps. Polymarket is geo-blocked for US users.
Which platform has the most accurate election odds?
Polymarket and Kalshi typically converge on similar implied probabilities for major US races because traders arbitrage between them. For non-US elections, Polymarket alone tends to set the price global media outlets cite.
Can I bet against a candidate?
Yes. Selling a yes contract or buying the no contract on the same outcome is functionally identical. Both express the view that the event will not happen.
Do election markets predict winners better than polls?
Markets have outperformed polls in many but not all major US elections since 2008. Polls measure stated intent. Markets aggregate the financial conviction of people willing to put money behind a forecast. Both are useful inputs, neither is infallible.
What happens if an election is contested?
On Kalshi, contracts settle based on the official certified result under CFTC oversight. Polymarket uses UMA’s optimistic oracle and may delay resolution if the outcome is disputed. Read each platform’s settlement rules before trading contested races.
