Prediction Marketplace Kalshi Said to Be Exploring IPO Path in Informal Talks With Banks

Key Takeaways

According to The Information report, the discussions are early stage. There is no S-1 filing, no banker selected and no public timeline. People close to the matter told the publication’s reporter Yueqi Yang that any listing is likely a year or more away, putting a realistic window at late 2027 or 2028.

Kalshi is asking something unusual of the banks it talks to. The company wants prospective advisers to integrate their own platforms with Kalshi first, giving their institutional clients direct access to trade on the exchange. Banks that want the IPO mandate have to bring trading volume to the table before they bring paperwork.

Revenue Growth Driving the Conversation

The talks come as Kalshi’s numbers move fast.

Annualized revenue run rate has passed $2 billion, roughly tripling since November 2025.
May 2026 notional trading volume hit a record near $17 billion, driven largely by NBA playoff and FIFA World Cup sports contracts.
Institutional trading volume jumped 800% over the six months ending in early May 2026, with annualized institutional volume reaching $178 billion.

Kalshi closed a $1 billion funding round in May 2026 led by Coatue, with Sequoia, Andreessen Horowitz, Paradigm, Morgan Stanley, and Ark Invest also participating. The round valued the company at $22 billion, up from $11 billion in December 2025.

From Retail App to Wall Street Target

Kalshi launched publicly in July 2021 after becoming the first federally regulated event-contract exchange in the United States. Founders Tarek Mansour and Luana Lopes Lara built the platform on contracts tied to elections, weather, economics and sports, with sports now making up the bulk of trading activity.

CEO Tarek Mansour has called event contracts a “trillion-dollar market” that could grow large enough to compete with traditional exchanges within a few years.

The institutional push backs that claim with infrastructure. Kalshi completed its first institutional block trade in April 2026, a carbon allowances contract brokered between a Texas hedge fund and a market maker. The company has also added partnerships with Tradeweb, Clear Street, Interactive Brokers and FIS to handle clearing and brokerage for larger players.

Why It Matters

A Kalshi IPO would be the first major listing from a CFTC-regulated prediction market operator. It would give banks, hedge funds, and asset managers a direct read on how Wall Street values event contracts as a financial asset class.

State-level legal challenges over sports contracts remain a risk. Several states have argued that Kalshi’s sports markets function as unlicensed sports betting, a dispute still working through courts. That overhang could shape how banks price any future offering.

For now, Kalshi’s growth gives it leverage. Record volume, a tripled revenue run rate and a $22 billion valuation make the company a rare case study in how fast a regulated prediction market can scale, with or without Wall Street’s help.
