Kalshi's numbers got too big to stay private. The prediction market platform has crossed $2 billion in annualized revenue, triple where it sat in November 2025, and it is now in early talks with investment banks about going public, according to The Information. For a four-year-old company that spent its first years arguing in court for the right to exist, that is a fast trip from courtroom to IPO roadshow. There is a catch, and it is also in a courtroom.
The timing tells you how serious this is, and how unsettled it still is. No listing is expected before late 2027 or 2028.
The numbers behind the IPO talk
Start with what is driving the conversation. Kalshi's annualized trading volume climbed from $52 billion to $178 billion over the past year, and institutional trading on the platform jumped 800% in the six months through early May. Monthly volume hit $16.81 billion in May, up from $14.81 billion in April, lifted by record activity around the NBA playoffs and the FIFA World Cup. The company now commands more than 90% of US prediction market activity. A few weeks ago it closed a $1 billion Series F led by Coatue at a $22 billion valuation, double its January mark, with Sequoia, Andreessen Horowitz, Paradigm, IVP, Morgan Stanley, and ARK Invest all in the round. Prediction markets were a curiosity a couple of years ago. Kalshi turned them into one of the fastest-growing businesses in US fintech.
One detail in the reporting stands out. Kalshi is asking the banks it courts as advisers to integrate directly with its platform, so their institutional clients can trade on it. That is not how a small exchange behaves. It is how an incumbent builds a moat. Founded in 2020 by Tarek Mansour and Luana Lage, the company plans to spend its fresh capital on block trading, risk products aimed at hedge funds, asset managers, and insurers, and upgrades to its core infrastructure. Everything about the spend points at Wall Street, not retail.
The badge that is also the risk
Here is the tension an IPO would have to price. Kalshi's biggest advantage is that it is a CFTC-regulated exchange, a status decentralized rivals like Polymarket cannot match, and the one thing that makes cautious institutions comfortable trading event contracts at all. That federal badge is the whole pitch. It is also exactly what is under attack right now. Kentucky sued Kalshi this week as an unlicensed sportsbook, and on the same day a federal judge in Michigan ruled that sports prediction markets do not fall under the CFTC at all. The asset that makes Kalshi attractive to Wall Street, its regulated standing, is the asset a red state and a federal judge are trying to chip away. An IPO prospectus would have to list that fight as a risk factor on page one.
What a listing would actually mean
If Kalshi goes public near its last private valuation, it would rank among the largest US fintech IPOs in years, and it would hand public investors their first clean way to own the prediction-market boom rather than bet inside it. That is the bull case, and the volume figures support it. The timing is the honest part of the story. The 2027 to 2028 window the company is floating is not just about market conditions. It lines up with how long the legal questions, and the CLARITY Act that could settle them in Washington, are likely to take to resolve. Kalshi appears to be timing its debut for after the fog clears, not before.
So the company spent four years turning event contracts from a legal gray zone into a $2 billion business and a $22 billion valuation, and going public would be the validation of all of it. The IPO and the lawsuits are now running on the same clock. Whichever crosses the line first will decide whether Kalshi lists as the regulated winner of a new market or as a company still arguing about what it is allowed to sell.
