Kalshi reportedly raises $1 billion, doubling valuation to $11 billion amid rapid industry expansion

Prediction market operator Kalshi has reportedly closed a $1 billion funding round that lifts the company’s valuation to $11 billion, following the accelerating adoption of event-based trading platforms worldwide.

The latest capital infusion arrives less than two months after Kalshi secured $300 million at a $5 billion valuation. According to reporting from TechCrunch, investors from previous rounds returned alongside new backers. The group includes Sequoia and CapitalG, joined by Andreessen Horowitz, Paradigm, Anthos Capital, and Neo.

The funding was announced at a time when prediction markets are drawing record participation. Platforms in this sector allow users to trade on outcomes ranging from elections and economic data to cryptocurrency prices and weather conditions. Kalshi has seen rival Polymarket aim for a valuation of $12 billion while newcomer Opinion challenges established leaders.

Recent data from Dune Analytics shows how closely contested the market has become. Weekly notional volume for Opinion reached $1.46 billion, slightly above Kalshi’s $1.2 billion. Polymarket followed with under $1 billion. Despite this competition, Kalshi has expanded its global user base and now operates in more than 140 countries. Official trackers place the company’s cumulative trading volume at more than $17 billion, with over 68.4 million transactions recorded to date.

Mainstream visibility for these platforms has also grown following Google Finance’s decision to integrate real-time market data from both Kalshi and Polymarket. The integration brings event-based trading indicators onto one of the most widely used financial information services.

Kalshi operates as a Designated Contract Market regulated at the federal level. “Kalshi is regulated by the Commodity Futures Trading Commission (CFTC) – an independent agency of the US government that has regulated US derivatives markets since 1974 and is overseen by Congress,” the firm noted. That federal oversight has not eliminated friction at the state level, where several regulatory challenges are unfolding simultaneously.

In Massachusetts, the state attorney general filed a lawsuit in September seeking to bar Kalshi from offering sports-related prediction products. In Nevada, US District Court Judge Andrew Gordon has suggested he may revisit an April decision that granted Kalshi a preliminary injunction blocking the enforcement of state gambling laws. Maryland regulators recently declined the company’s request for a similar injunction.

In New York, Kalshi has taken a different approach by filing its own lawsuit to prevent state authorities from categorizing its sports prediction markets as illegal gambling.
