Kalshi raises $1B, hits $22B valuation and $1.5B ARR as legal battle looms
Kalshi, the New York-based prediction markets platform, has raised $1B in a Series F round led by Coatue Management at a $22B valuation — roughly double its $11B valuation from five months ago. Sequoia Capital, Andreessen Horowitz, IVP, Paradigm, Morgan Stanley, and ARK Invest also participated.
Annualised trading volume on Kalshi tripled in six months, rising from $52B to $178B, and annualised revenue has surpassed $1.5B, driven primarily by sports markets which accounted for nearly 90% of its 2025 revenue.
Kalshi allows users to buy and sell contracts on the yes-or-no outcomes of real-world events — from elections and economic data to sports results. The company argues its products are financial derivatives regulated by the Commodity Futures Trading Commission, not sports bets subject to state gambling law.
Prediction markets have moved from niche to mainstream. The 2024 US election cycle brought Kalshi and rival Polymarket into the public eye as their political markets outperformed traditional polling. Sports markets followed, and the combination of retail and institutional demand has driven explosive growth.
Kalshi's institutional investor base — which now includes Morgan Stanley — reflects a shift from early crypto-native backing toward mainstream financial services validation.
The timing of the raise is also notable given Kalshi's legal situation. A Massachusetts lower court ruled in January 2026 that Kalshi was operating as an unlicensed sportsbook within the state and issued an injunction blocking its sports markets there.
On May 4, 2026, Kalshi's lawyer appeared before the Massachusetts Supreme Judicial Court to appeal — arguing that as a CFTC-regulated exchange, Kalshi is not subject to state gambling law, and that its products are swaps rather than bets. The outcome remains pending.
The Massachusetts case is the most immediate risk. If the state Supreme Court upholds the injunction, other states may follow — a serious threat given that sports markets generated nearly 90% of Kalshi's revenue in 2025. Kalshi has literally advertised itself as "the first app for legal sports betting in all 50 states" — marketing that state regulators are now using against it in court.
The regulatory question is genuinely unsettled. Whether prediction market contracts on sports outcomes are CFTC-regulated derivatives or state-regulated bets is a legal distinction that courts have not yet resolved definitively, and the outcome will shape the entire prediction markets industry.
Kalshi's $22B valuation — achieved while facing an active state-level injunction on its core revenue stream — reflects extraordinary investor conviction in the prediction markets category. The bet is that federal regulatory jurisdiction will ultimately prevail over state gambling law, opening a legal path to operate sports markets nationally.
If that bet pays off, Kalshi could become one of the most valuable financial platforms of the decade. If it doesn't, the business model faces an existential restructuring.
Rival Polymarket is seeking funding at a $15B valuation. The prediction markets category is being priced as if the legal question is already resolved — which it isn't.
