Midterms to Subject Prediction Markets to Reputational Stress Test
Users have staked more than $1.4 billion on midterm contracts as the platforms face questions over accuracy, insider trading and legality.
- On Tuesday, nearly $1.9 billion had been wagered on U.S. midterm elections across Kalshi and Polymarket prediction markets as of Monday evening, marking record betting levels for election contracts.
- Prediction markets have shifted into the mainstream, with Kalshi valued at $40 billion in its latest fundraising round last month and Polymarket at $21 billion in August, reflecting surging institutional backing.
- Financial technology worker Noah Poser built quantitative models to track dozens of wagers, while Florida State University student Yadin Eldar bets on races he considers "extremely underpriced" for potential 50-55% profits.
- Legal challenges from a bipartisan coalition of state attorneys general in New York and Utah have alleged the platforms operate as illegal gambling, while Polymarket recently investigated dozens of midterm trades for potential insider manipulation.
- Industry leaders prioritize "long-term development and credibility" over election outcomes, though critics contend the platforms function as "gambling, just disguised as predictions," raising questions about sustained regulatory acceptance.
