Kalshi has successfully raised approximately $1 billion in a recent funding round led by Coatue Management, effectively doubling its valuation to $22 billion within just a few months. This surge in interest comes despite ongoing legal challenges faced by prediction market operators in the United States.
This latest funding follows earlier reports indicating that both Kalshi and its competitor, Polymarket, were in search of new investments, each aiming for valuations of at least $20 billion. The Wall Street Journal was the first to break the news of this funding round.
The rapid increase in Kalshi's valuation can be attributed to a series of capital raises within a short timeframe. Approximately nine months prior, Kalshi raised $185 million at a valuation of $2 billion, with notable investors including Sequoia Capital, Multicoin, Neo, Bond Capital, and Citadel Securities CEO Peng Zhao.
In October 2025, another funding round of $300 million raised the company's valuation to $5 billion. A subsequent $1 billion raise just two months later further increased the valuation to $11 billion, and the latest financing has now doubled that amount once more.
Despite this impressive growth, Kalshi is currently facing legal hurdles at the state level. Just a day before the funding news broke, Arizona Attorney General Kris Mayes filed a 20-count criminal complaint against the company, accusing it of unlawfully offering contracts related to political and sports events in the state.
Arizona has become the first state in the U.S. to file criminal misdemeanor charges against a prediction market operator, heightening tensions between state regulators and this emerging industry.
The allegations claim that Kalshi's platform offered contracts linked to various events, including professional and college sports, the 2028 U.S. presidential election, and several races in Arizona scheduled for 2026, such as the gubernatorial election and the Republican primary.
Kalshi's CEO and co-founder, Tarek Mansour, has publicly criticized these actions, stating, “If this were truly about consumer protection, the state would be addressing the exploitative practices of the gambling industry’s addiction-driven model. Instead, a regulated exchange is being targeted to safeguard established players and limit consumer choice.”
He emphasized the company's commitment to its nearly 400,000 customers in Arizona, representing about 5% of the state's population, and vowed to continue their fight against these legal challenges.
Investor interest in this latest funding round reflects a strong belief in the prediction market sector, despite ongoing regulatory uncertainties. Coatue Management’s involvement marks its first direct investment in Kalshi and its initial engagement with a dedicated prediction market operator. The firm has previously invested in Webull, a brokerage platform that collaborates with Kalshi to offer event contracts.
Kalshi's current valuation surpasses that of several publicly traded sports betting companies. At $22 billion, it is valued $3.34 billion more than Flutter Entertainment and $9.54 billion more than DraftKings.
Meanwhile, states such as Massachusetts, Nevada, and Michigan have initiated civil actions to prevent Kalshi from offering sports event contracts. A judge in Massachusetts has issued an injunction against such offerings, although this ruling is currently on hold pending an appeal.
Earlier this month, Ohio denied Kalshi’s request for a preliminary injunction against state regulators, ruling that the company must adhere to state gambling laws.
