The prediction market is pricing two things at once: Kalshi's future, and whether the company's future is even legal in the states where it operates.
On Thursday, Kalshi confirmed the completion of a $1 billion Series G at a $40 billion post-money valuation, co-led by Wellington Management and Sequoia Capital with ten co-investors including Andreessen Horowitz, Coatue, and CapitalG, according to Cointelegraph. The price tag is 82% higher than May's $22 billion valuation — and eight times where Kalshi stood in October 2025. The company says it has now brought in $3.3 billion across four rounds in a single year.
The timing is what makes it strange. The funding announcement landed a day after Utah filed criminal charges against Kalshi and its co-founders, CEO Tarek Mansour and COO Luana Lopes Lara, accusing the company of promoting illegal gambling in the state — the sharpest escalation yet in the jurisdictional war over whether prediction-market contracts are federally regulated derivatives or state-regulated gambling. The CFTC has sued to block Utah's enforcement, and Kalshi won an appeals-court ruling in New Jersey this spring — but the legal ground under its sports contracts remains contested in courtrooms across the country.
Kalshi's answer to the doubters is the non-sports business. The company says non-sports markets now generate more than $1 billion in annualized revenue, with annualized trading volume topping $1 trillion overall and Kalshi holding roughly 75% of prediction-market volume. Sports put the brand on the map; the pitch now is a "next-generation financial exchange" — indices, single-stock perpetual futures, compute markets — aimed at institutions rather than parlay bettors.
Investors just bet $1 billion that the distinction will hold in court. If a jury in Utah disagrees, the most expensive private round of the year could turn into the most expensive legal experiment in prediction-market history.
