Kalshi has launched a dedicated hub for the 2026 US midterm elections, combining live prediction market prices with polling, fundraising data and political news.
The launch of Kalshi's Midterms Hub follows the breakout moment for prediction markets during the FIFA World Cup, when the company and its primary rival, Polymarket, added millions of users, with billions of dollars traded across the tournament.
The midterms will now provide the first major test of whether that new audience will use prediction markets to follow politics, and whether live prices can challenge incumbent pollsters and broadcasters. It's also a way for Kalshi to differentiate itself as a host of rivals from both crypto and traditional finance (TradFi) have entered the red-hot prediction-market space.
Live markets challenge polling cycles
Midterms Hub covers House, Senate and gubernatorial races through a US national map showing the probabilities implied by individual contracts. It also carries polling averages, Federal Election Commission fundraising reports, historical results and curated news from third parties.
Traditional polling companies, such as Gallup or Ipsos, measure voter sentiment through periodic surveys. Prediction markets instead show where participants are willing to risk money, with prices that can adjust within seconds after debates, endorsements, economic releases or campaign developments.
"Prediction markets don't care about spin or partisanship. They cut through polarization and show you what the wisdom of the crowds actually believes, backed by real money, not rhetoric," said Kalshi co-founder and CEO Tarek Mansour, in a statement.
"That kind of clarity is rare right now and that's what people are getting with the Midterms Hub."
Kalshi began offering federal election contracts in October 2024 after winning a court challenge over their legality. Its presidential winner market later drew about $536mn, while the platform recorded $1.27bn in total volume in November that year, while politics and elections generated roughly $1.13bn, or 89%, of that activity, according to Dune data.
Polymarket's presidential winner market recorded about $3.69bn in 2024, showing the scale of demand for event-based trading volume.
Market prices are not inherently more reliable than polls. Thin liquidity, participant bias and ambiguous contract terms can distort probabilities. The hub's inclusion of polling averages allows users to see where surveys and market expectations diverge.
Election coverage as traded product
Kalshi said about 75% of its visitors check probabilities without trading. That means the platform is increasingly competing for news audiences as well as trading activity.
The World Cup showed how quickly a familiar event can bring prediction markets into mainstream use. Contracts moved after goals, injuries and red cards, while major markets developed enough depth to become widely followed information signals.
Politics offers a similar cycle of continuous events. A debate performance, candidate withdrawal or economic report can now produce an immediate market reaction before a new poll is published or a broadcaster assembles a panel.
Kalshi has also moved closer to established media through distribution partnerships that place its probabilities inside election coverage. Its American Power Index already tracks the relative standing of the two major parties.
The private company does not publish audited revenue. It said annualized revenue exceeded $1.5bn in May, while annualized trading volume reached $178bn.
The November elections will show whether prediction-market prices become a durable feature of political reporting. Pollsters and broadcasters may increasingly have to explain not only what voters say, but why traders disagree.
