Kalshi IPO: Prediction market on the verge of historic listing, but regulatory risks are mounting
Prediction market platform Kalshi, demonstrating explosive financial growth, has officially entered preliminary discussions with investment banks regarding a potential initial public offering (IPO). The market listing is expected to take place between late 2027 and early 2028.
The decision to prepare for an IPO is directly linked to the phenomenal business performance. Kalshi's annual revenue has already surpassed the $2 billion mark, approximately three times the level seen in November 2025. This surge is a direct consequence of rapidly growing interest in sports markets.
Sports as the Main Growth Driver
In May 2026, the platform's monthly trading volume reached $16.81 billion, a 13.5% increase from April figures. The main catalysts were a spike in activity around the NBA markets and the FIFA World Cup (2026 World Cup). Additionally, Kalshi strengthened its position by becoming a partner of the National Hockey League (NHL).
Investor financial appetite is also impressive. In May, Kalshi raised $1 billion in a Series F round at a valuation of $22 billion. The round was led by Coatue, with participants including Sequoia Capital, Andreessen Horowitz, Paradigm, Morgan Stanley, and ARK Invest. Since the start of 2025, the company has closed four major funding rounds.
In parallel, Kalshi launched CFTC-approved perpetual futures on Bitcoin (BTC) and other crypto assets. However, this move drew criticism from CME Group, which insists on different regulation for such contracts.
Regulatory Time Bomb
The main risk for Kalshi, as for the entire prediction market sector, is regulatory uncertainty. This week, the state of Kentucky filed a lawsuit against Kalshi and Polymarket over allegedly unlicensed sports betting. Similar documents were filed by representatives from Wisconsin, New York, Nevada, and other states. U.S. gaming associations have called on the Senate to include a ban on sports prediction markets in the Clarity Act bill.
Simultaneously, the Commodity Futures Trading Commission (CFTC) insists that prediction markets fall solely under its jurisdiction and is suing several states attempting to restrict them. In April 2026, a New Jersey court sided with Kalshi, allowing it to offer sports contracts, but the final word will likely rest with the U.S. Supreme Court.
My analysis: Kalshi's IPO is undoubtedly a landmark event for the entire industry, potentially attracting institutional capital and strengthening the legitimacy of prediction markets. However, the company is playing a dangerous game. If courts rule sports markets illegal, Kalshi could lose up to 90% of its revenue, rendering IPO discussions moot. Investors should closely monitor the legal battles, not just the financial reports.
