The CFTC-regulated platform has pulled in over a billion dollars since April, with a $40B valuation conversation now reportedly underway
Kalshi has quietly become one of the fastest-growing financial platforms in the US, and the money is starting to reflect that. The New York-based prediction market operator has raised approximately $1.12 billion through a private equity offering that kicked off on April 3, 2026, according to a Form D filing made public on August 26.
The filing shows 71 investors have participated so far, with roughly $380 million still available under the offering. The total target sits at approximately $1.5 billion, meaning Kalshi is about three-quarters of the way to its goal.
One raise wasn’t enough
The private equity offering runs alongside a separate $1 billion Series F round that Kalshi closed in May 2026, which pegged the company’s valuation at $22 billion. That round was led by Coatue, with Sequoia Capital and Andreessen Horowitz among the participants.
Reports from June through August 2026 indicate the company is in separate discussions for a $750 million round that would value the business at $40 billion.
The trading numbers that explain everything
Kalshi’s annualized trading volume reached $178 billion by April 2026, up from roughly $5 billion a year prior. Institutional trading volume climbed 800% over the six-month stretch leading into April 2026, driven substantially by sports contracts.
The company claims a market share of somewhere between 90% and 95% of the US prediction market. Kalshi also reports annualized revenues exceeding $2 billion.
What Kalshi actually is, and why it matters now
Kalshi operates under CFTC oversight as a designated contract market. The platform lets users trade on the outcomes of real-world events, from election results to economic data releases to sports outcomes. The payout structure is binary: either the event happens or it doesn’t, and the contract settles accordingly.
Co-founders Tarek Mansour and Luana Lopes Lara built the company with an explicit long-term ambition, and the next milestone they’re reportedly eyeing is an IPO as early as 2027.
What the funding wave signals for the broader market
The 800% jump in institutional trading volume is particularly telling. Prediction markets are increasingly being used for hedging strategies alongside traditional futures and options. Platforms like Polymarket operate in a similar information space but without the US regulatory clearance that has allowed Kalshi to court institutional clients openly.
