From Betting on Trump to Wagering on the NFL: Prediction Markets Set to Hit All-Time Highs in 2025

December 26, 2025 marked a milestone for the prediction market industry, with platforms Polymarket and Kalshi leading the charge—driving surges in investment, media coverage, and valuations as the space inches toward mainstream acceptance. With the 2026 U.S. midterm elections on the horizon, the prediction market is poised to replicate the trading frenzy seen during the 2024 presidential race. The key question now: Can these platforms transition from being “traffic and topic-driven” to scalable prediction infrastructure? ### Capital Flows & Valuation Surges - **Kalshi**: Secured $1 billion in November funding (led by Sequoia Capital and CapitalG) at an $11 billion valuation, following an October $300 million Series D round that valued it at $5 billion. - **Polymarket**: NYSE parent ICE invested $2 billion, with CEO Shayne Coplan later disclosing a ~$9 billion valuation. Analysts note the prediction market’s core value lies not in short-term revenue, but in collective intelligence and globally distributed predictive data. Sportstensor CEO Leo Chan adds this data is highly valuable to both financial institutions and non-trading users. During the 2024 U.S. presidential election, prediction market trading volumes spiked—with Chainalysis estimating a French Polymarket whale netted $78.7 million betting on Trump’s victory. In 2025, the two platforms ramped up partnerships: - Kalshi teamed with CNBC and CNN - Polymarket partnered with Yahoo Finance and UFC - NHL signed multi-year licensing deals with both platforms As midterms near, the prediction market is set for another boom. But consensus holds 2026 will be a watershed year to test the space’s long-term value: Whether platforms can prove their unique role in information discovery, risk pricing, and decision support will determine if the sector moves from frenzy to maturity.
