Kalshi holds early IPO talks, seeks bank integrations

Kalshi has opened early, informal discussions with investment banks about a potential initial public offering and is asking prospective advisers to connect their trading platforms to the exchange and demonstrate they can bring institutional trading volume before formal IPO paperwork is filed. According to people familiar with the talks, there is no S-1 filing, no lead underwriter selected and a public listing is likely a year or more away.

The company’s requirement asks banks to enable their institutional clients to trade directly on Kalshi and to prove they can route meaningful volume to the marketplace. Company executives view platform integration and committed volume as evidence of demand from large financial clients ahead of any public offering.

Kalshi’s recent financial and trading metrics have accelerated. The exchange’s annualized revenue run rate has topped $2 billion, roughly triple the level in November 2025. Notional trading volume reached about $17 billion in May 2026, driven largely by sports contracts tied to the NBA playoffs and the FIFA World Cup. Institutional trading volume rose roughly 800% over the six months ending in early May 2026, producing an annualized institutional volume figure of $178 billion.

In May 2026 Kalshi closed a $1 billion financing round led by Coatue that valued the company at $22 billion, up from $11 billion in December 2025. Other investors in the round included Sequoia, Andreessen Horowitz, Paradigm, Morgan Stanley and Ark Invest.

Kalshi launched publicly in July 2021 as the first federally regulated event-contract exchange in the United States. Founders Tarek Mansour and Luana Lopes Lara built contracts tied to elections, weather, economic outcomes and sports; sports-related markets now account for the bulk of activity on the platform. Mansour has described event contracts as a “trillion-dollar market.”

The company has taken steps to broaden institutional access. Kalshi completed its first institutional block trade in April 2026, a carbon allowances contract between a Texas hedge fund and a market maker, and has established clearing and brokerage relationships with Tradeweb, Clear Street, Interactive Brokers and FIS to support larger counterparties.

Legal and regulatory questions remain. Several U.S. states have challenged Kalshi’s sports contracts as unlicensed sports betting; those disputes are pending in the courts and could affect how underwriters and investors value the exchange and its products.

People close to the discussions say formal IPO preparations are unlikely to begin for at least a year, putting a realistic listing window in late 2027 or 2028 depending on market conditions and whether banks meet the integration and volume targets.
