The First Prediction-Market Election: How Kalshi and Polymarket Scrambled the Midterms
Tap title to read story
As the 2026 U.S. midterm elections approach, prediction market platforms such as Kalshi and Polymarket are experiencing a historic surge in trading activity, introducing complex challenges for election administrators, regulators, and voters. Total trading volume across major prediction platforms has escalated to $26.6 billion, according to blockchain analytics firm Dune, marking a sharp increase from previous cycles. Roughly two-thirds of this volume is concentrated on Kalshi, a federally regulated exchange that achieved a $22 billion valuation in its most recent funding round. State election officials across approximately 20 states have raised alarms that real-money wagers on congressional, gubernatorial, and local races could distort public expectations, influence voter behavior, or facilitate market manipulation. Concurrently, intense legal battles are playing out in federal and state courts to determine whether state-level gaming regulators possess the authority to oversee prediction exchanges or if federal commodities laws preempt local jurisdiction. In response to heightened regulatory pressure and scrutiny over potential conflicts of interest, prediction market operators have enacted stringent compliance measures, including rules barring political candidates from wagering on their own campaigns.
