According to an announcement, Kalshi, the top federally regulated prediction market platform, has received an additional $200 million in funding in a Series F extension round. This new infusion of funds is in addition to the enormous $1 billion Series F funding that the company completed early this month.
The extension round is led by big new backers Baillie Gifford and Layer Global. This maintains the $22B post-money valuation of Kalshi. The extended round is evidence of the surging institutional appetite for event-based financial instruments, making prediction markets one of the fastest-growing asset classes apart from AI.
Institutional Capital Floods Event Contracts
The $200 million extension (Kalshi’s second tranche) follows directly from Kalshi’s first Series F tranche led by Coatue Management. The first tranche was backed by a team of top Silicon Valley and Wall Street players, among them Sequoia Capital, A16z, IVP, Paradigm, Morgan Stanley, and ARK Invest.

This enormous investor interest coincided with an unprecedented increase in overall platform activity. Kalshi experienced a record all-time monthly trading volume of $14 billion for April 2026. This increase has, in turn, propelled the platform’s annual revenue to cross $1.5 billion. Most of this volume was fuelled by big investment firms using event contracts to mitigate macroeconomic and geopolitical risks. Institutional trading volume on Kalshi has increased by 800% in the last six months alone, thus transforming the platform from a consumer product novelty to a baseline of institutional trades.

Regulatory Moats and Market Dominance
Distinct from some of its decentralised and offshore rivals, Kalshi is a regulated financial exchange regulated by the CFTC. This adversarial regulation has become a defining advantage against Kalshi among institutional capital seeking access from traditional asset managers, hedge funds, and insurance companies, all of whom cannot touch unregulated platforms.
Today, Kalshi has captured over 90% of all regulated prediction market activity in the U.S. On its platform, users can speculate on the success of real-world events by trading financial instruments tied to future events such as interest rate moves decided by the Federal Reserve, economic data releases, climate indicators, and elections. With its new capital, Kalshi will spearhead building its institutional product offering, including its newly introduced block trading offerings, enhanced risk management capabilities, and strengthened integrations with the leading prime brokers.
Navigating Political and Public Pressures
The rapid growth of prediction markets has not gone unnoticed. Congress, in particular, is growing increasingly wary of the potential implications of event-based trading. In the United States, the Senate quietly passed legislation to prevent senators and their aides from participating in prediction markets.
Kalshi’s $2M investment in the National Council on Problem Gambling proactively addresses public perception, positioning it as a legitimate financial exchange, not a gambling platform. The company now accesses $1.2B in Series F capital to counter regulatory challenges, targeting $10B in premium volume and a trillion-dollar events class.
