Prediction-market operator Kalshi has secured $1 billion in fresh funding, bringing its valuation to $40 billion, according to Reuters. The financing round, co-led by Sequoia Capital and Wellington Management with participation from Tiger Global Management and Dragoneer Investment Group, marks the company's second billion-dollar capital raise in approximately five months.
The new valuation represents an 82% increase from May's $22 billion figure. Kalshi, founded by MIT classmates Tarek Mansour and Luana Lopes Lara, operates a federally regulated exchange where traders purchase contracts tied to future events. A contract priced at 65 cents, for instance, indicates a market-implied 65% probability of that outcome occurring.
Expansion Into Derivatives Markets
The latest funding positions Kalshi to compete with established derivatives operators including CME Group and Intercontinental Exchange, parent company of the New York Stock Exchange. The company has expanded into cryptocurrency perpetual futures, equity indexes, and metals following regulatory approval, with ambitions extending to individual-stock perpetuals and leveraged event contracts.
Trading activity underscores investor confidence. Kalshi reported that annualized volume more than tripled between May's previous funding round and the announcement, climbing from approximately $52 billion to $178 billion. Institutional activity increased 800%, with the company working alongside 500 institutional entities accounting for roughly one-quarter of trading volume excluding market makers.
The broader prediction-market industry has experienced similar growth, with annual trading volume expanding from approximately $500 million in 2022 to more than $63 billion in 2025.
Regulatory Challenges Over Sports Contracts
State authorities have challenged Kalshi's sports-related event contracts, arguing they constitute gambling subject to state oversight rather than derivatives governed exclusively by federal regulators. Sports contracts have reportedly accounted for approximately 65% of Kalshi's revenue at certain points, making unfavorable rulings potentially costly.
Mansour has suggested the dispute could eventually reach the Supreme Court. Competition with crypto-native rival Polymarket continues to intensify, with Kalshi capturing approximately 72% of trading volume across major prediction-market venues during the third quarter of 2026.
Future Growth and Public Markets
Kalshi's leadership has discussed pursuing an initial public offering, though Mansour has ruled out a 2026 debut. Subsequent commentary has pointed toward 2027 or 2028 as possible windows, depending on market conditions and regulatory developments.
