Prediction market platforms Polymarket and Kalshi secured the largest U.S. funding rounds in 2025. Polymarket raised $2 billion in an October round led by Intercontinental Exchange at a $9 billion valuation.
Kalshi followed with $300 million in October and $1 billion in December, reaching an $11 billion valuation.
Global fintech companies raised $55.94 billion across 3,712 deals in 2025, according to PitchBook data cited by Bloomberg.
This marked a 25% increase from $44.75 billion in 2024. The total remained below the 2021 peak of $123.99 billion.
These rounds stood out in a year when deal volume fell 19% from 2024. Investors concentrated capital on established players in prediction markets, where users trade contracts on real-world event outcomes.
Why This Matters Today
Fintech venture funding rose in 2025 for the first time in four years. Prediction markets captured significant investor interest amid growing trading volumes on platforms offering bets on events like elections and economic indicators.
A more favorable regulatory environment under the Trump administration eased restrictions on banking partnerships and event contracts.
This shift supported growth for regulated platforms like Kalshi and enabled Polymarket’s U.S. re-entry after prior settlements.
Industry observers noted capital flowing to perceived category leaders. Matt Streisfeld, a partner at Oak HC/FT, told reporters that investors now double down on market winners rather than fund multiple new entrants.
Our Key Takeaways:
- Polymarket raised $2 billion and Kalshi raised $1.3 billion in 2025, accounting for the top U.S. fintech funding rounds.
- Worldwide fintech venture capital totaled $55.94 billion in 2025, up 25% from 2024 but still far below 2021 levels.
- Investors should monitor prediction market growth and potential additional raises, as Polymarket explored further funding at higher valuations.
