Kalshi has reportedly secured approximately $1 billion in a recent funding round led by Coatue Management, effectively doubling the firm’s valuation to $22 billion within a few months. This significant development occurs amidst increasing investor interest in prediction market platforms, despite existing legal challenges in the United States.

This funding round follows earlier announcements that Kalshi, alongside competitor Polymarket, had been seeking additional capital with valuations starting at $20 billion. The details of this latest financing were initially disclosed by The Wall Street Journal.

The impressive surge in Kalshi’s valuation comes from consecutive funding rounds executed within a brief timeframe. Approximately nine months prior, Kalshi raised $185 million at a valuation of $2 billion, gaining support from notable investors such as Sequoia Capital, Multicoin, Neo, Bond Capital, and Citadel Securities CEO Peng Zhao.

A $300 million funding round in October 2025 elevated the valuation to $5 billion. Just two months later, an additional $1 billion raised brought the valuation up to $11 billion. This newest round has now doubled that valuation.

Notably, this remarkable growth in valuation is occurring even as Kalshi faces state-level legal challenges. Just prior to the funding news, Arizona Attorney General Kris Mayes filed a criminal complaint consisting of 20 counts against the company, accusing it of unlawfully offering contracts related to political and sports events within the state.

Arizona becomes the first U.S. state to file misdemeanor charges against a prediction market operator, heightening conflicts between state regulators and this emerging sector.

According to prosecutors, the platform has offered contracts linked to events including professional and college sports, the U.S. presidential election in 2028, and multiple elections in Arizona in 2026, such as the gubernatorial race, the Republican primary, and the secretary of state election.

Kalshi’s CEO and co-founder Tarek Mansour has condemned the actions taken. “If this were truly about protecting consumers, Arizona would instead address the exploitative practices prevalent in the gambling industry’s addiction-focused model. Rather, a regulated exchange is being targeted to safeguard incumbents and restrict consumer choices,” he voiced on X.

“We have nearly 400,000 customers in Arizona, representing about 5% of the state’s population, and we intend to advocate for them. We won’t be deterred, and we will continue our growth.“

The rule of law applies to all – even state governments.

The charges brought forth by the Arizona Attorney General are unfounded and represent an excessive reach. This is merely political maneuvering from someone looking to re-elect themselves.

Involvement in this latest funding round illustrates confidence in the prediction market industry, despite the ongoing regulatory concerns. The participation of Coatue Management marks its initial direct investment in Kalshi and its first known engagement with a dedicated prediction market platform. The firm has previously invested in brokerage platform Webull, which provides event contracts in association with Kalshi.

Kalshi’s valuation now surpasses that of numerous publicly traded sports betting companies. At $22 billion, it exceeds Flutter Entertainment’s valuation by $3.34 billion and DraftKings by $9.54 billion.

In parallel, Massachusetts, Nevada, and Michigan are pursuing legal actions aimed at curtailing Kalshi from offering sports event contracts. A judge in Massachusetts has issued an injunction preventing such offerings, although the ruling is currently on hold pending an appeal.

Earlier this month, Ohio rejected Kalshi’s bid for a preliminary injunction against state regulators, stating that the company must adhere to existing state gambling laws.
