This latest valuation represents a remarkable doubling from December 2025, when the platform secured $1 billion at an $11 billion price tag. That previous financing was anchored by Paradigm and attracted participation from notable investors including Sequoia Capital, Andreessen Horowitz, ARK Invest, and CapitalG, the investment arm of Alphabet.

Kalshi was established in 2018 by co-founders Tarek Mansour and Luana Lopes Lara. The platform functions as a federally regulated financial exchange under the supervision of the Commodity Futures Trading Commission, holding the distinction of being America’s first regulated prediction market exchange.

The service enables participants to trade contracts based on real-world events—spanning political elections, commodity prices like oil, and even speculative scenarios such as the official confirmation of extraterrestrial life. Its user ecosystem encompasses retail traders, institutional market-makers, and corporations utilizing the platform for hedging specific event risks.

February marked a significant milestone as platform trading volume exceeded $10 billion. This figure represents approximately twelve times the volume registered half a year prior, based on data from KalshiData. Currently, the company reports annualized revenue of $1.5 billion.

According to an individual with knowledge of the matter cited by the Wall Street Journal, investor enthusiasm for this funding round has been partially fueled by expansion in Kalshi’s institutional business segment.

Polymarket, Kalshi’s primary competitor, has experienced comparable growth trajectories but primarily serves markets outside U.S. borders. Recent valuations for both platforms have clustered around the $20 billion mark.

Mounting Legal Challenges From State Authorities

Notwithstanding its impressive expansion, Kalshi confronts significant legal obstacles. This week, Arizona prosecutors filed 20 criminal counts against the platform, charging it with operating an illegal gambling operation without proper licensing and facilitating election betting within state boundaries. Kalshi has characterized these state-level allegations as “seriously flawed.”

On Thursday, the Ninth Circuit Court of Appeals rejected Kalshi’s motion to prevent an anticipated temporary restraining order in Nevada. This judicial decision enables Nevada authorities to move forward with banning the platform’s operations throughout the state.

Kalshi has initiated litigation against several states attempting to implement similar prohibitions. The company maintains that it operates under federal CFTC jurisdiction and therefore lies outside the scope of state gambling regulations. Currently, more than a dozen state-level enforcement actions are proceeding nationwide.

Insider Trading Investigations Draw Additional Attention

Last month, Kalshi publicly disclosed that it had identified and sanctioned two users for insider trading violations. One individual among those penalized was an editor with connections to MrBeast, the widely followed social media influencer.

The company further revealed it maintains more than a dozen active insider trading investigations from a total of approximately 200 cases it has examined.

When approached by media organizations regarding the new financing round, Kalshi representatives declined to provide comment.
