Kalshi Launches Midterms Hub as Election Trading Volume Nears $200 Million

Kalshi, a federally approved financial exchange regulated by the Commodity Futures Trading Commission as a Designated Contract Market, has launched its Midterms Hub, a new platform that provides real-time insight into how traders are positioning themselves ahead of this fall's US midterm elections. The hub gives anyone with an internet connection a live view of where money is moving across Senate, House, and gubernatorial races nationwide. Unlike offshore prediction market platforms that operate outside US regulatory oversight, Kalshi's contracts are subject to CFTC supervision, a distinction the company has emphasized as it courts mainstream audiences.

The company stated the tool was built for voters, journalists, campaign staff, and researchers seeking up-to-date information on competitive races. It aggregates multiple streams of election-related data in a single interface. Users can compare polling averages against prediction market expectations through the platform's VoteHub feature.

The hub also displays the latest Federal Election Commission campaign finance filings, including each candidate's total fundraising figures and the percentage of contributions under $200 — a metric that indicates whether support is driven primarily by large donors or small-dollar grassroots contributors. Additional features include curated political news coverage and historical presidential election results from 2020 and 2024, broken down by state and congressional district.

Because Kalshi's markets operate around the clock, odds shift in real time whenever new polls are published, candidates make headlines, or debates conclude. Kalshi announced the launch on its official blog. CEO Tarek Mansour also shared the announcement on X.

Track Record and Transparency

Kalshi reports that candidates favored by its traders have won approximately nine out of ten elections since 2024, including races called three months before Election Day. The Washington Post independently examined hundreds of 2026 primary contests on the platform and found that roughly 75% were won by candidates whose odds ranged between 70% and 80%. Prediction markets have gained broader attention in recent election cycles as an alternative signal to traditional polling, which faced credibility challenges after high-profile misses in 2016 and 2020.

Mansour, an MIT graduate who previously worked as a trader at Citadel and an analyst at Goldman Sachs, argues that prediction markets are harder to manipulate with partisan framing than traditional polls or commentary. He says the Midterms Hub reflects financially backed forecasts rather than political rhetoric, making it a valuable source of electoral insight.

According to the company, approximately 75% of Kalshi visitors do not place any trades. Instead, they use the platform to observe how election contracts are currently priced.

Midterm Trading Approaches $200 Million

The Midterms Hub rollout follows a 2024 court ruling that legalized betting on federal elections in the United States, overturning a prior CFTC decision that had blocked Kalshi's election contracts. The ruling opened the door for regulated election prediction markets after years of regulatory uncertainty.

In May of this year, Kalshi introduced the American Power Index, known as KPOW, which Mansour described as a political power index comparable to the S&P 500. The metric combines current governing majorities with trader projections, displayed as a single figure on a scale ranging from positive 50 for Democrats to positive 50 for Republicans.

Trading volume has been climbing steadily. Kalshi alone has generated over $30 million in contracts tied to which party will control the House and Senate after November. Total volume wagered on midterm outcomes — including rival platform Polymarket, which operates offshore and agreed to settle CFTC charges in 2022 over its derivatives offerings — has surpassed $200 million. Kalshi has previously seen record daily crypto contract volume and has also been linked to Coinbase trading activity alongside Polymarket.

To mark the hub's debut, Kalshi hosted an event in Washington, D.C. Democratic strategist Stephanie Cutter moderated a discussion featuring Mansour, Republican pollster Kristen Soltis Anderson, and former White House Director of Digital Strategy Rob Flaherty.

Expansion into Drug Trial Betting

Kalshi is also expanding into a new domain: allowing users to trade on the outcomes of clinical drug trials and Food and Drug Administration rulings. The move represents one of the company's most significant steps beyond political and crypto markets into sectors with direct public health implications.

The company partnered with AppliedXL, a pharmaceutical data tracking firm, to verify which official documents will determine the resolution of each contract. Three rules govern the pilot program:

  • Trading is limited to late-stage trials only.
  • Markets open only after patient enrollment has concluded, preventing trading activity from influencing recruitment.
  • The platform analyzes employment records to bar individuals with inside knowledge, such as trial investigators, from participating.

The initiative has drawn pushback from medical researchers and healthcare professionals. According to Stat News, several experts have expressed concern about the long-term implications of allowing public trading in markets tied to clinical trial outcomes.
