What happened
Kalshi, the CFTC-regulated event-contract exchange run by CEO Tarek Mansour, is in advanced talks to raise around $1 billion at a $40 billion valuation, CryptoBriefing reported on Tuesday. Tiger Global and Dragoneer are leading the round, per the same report. Neither firm has publicly commented, and Kalshi has not confirmed the terms.
The figure would represent a sharp step up from Kalshi's $2 billion valuation earlier this year, when Paradigm led a Series C, and puts the New York-based platform in the same weight class as some of the largest private fintechs. It also lands during a stretch when Kalshi's political, macro, and sports contracts have been posting record notional volume.
Why it matters
A $40 billion tag on a regulated prediction-market venue reframes the category. For years, event contracts were treated as a fringe product tolerated by regulators and dominated on the crypto side by Polymarket, which routes on Polygon and settles in USDC. A round of this size, led by two crossover investors that price public tech, signals that the buy side now views prediction markets as an institutional asset class with a durable fee stream.
It also tightens the screws on Polymarket's US ambitions. Kalshi already won a federal appeals-court fight in 2024 to list political contracts, and a raise of this magnitude gives it the balance sheet to press that edge into sports, macro, and crypto-native events without touching a token.
Market impact
There is no direct token to trade against the headline, and that is part of the story. Kalshi settles in dollars, custodies with regulated partners, and does not need on-chain rails to function. The read-across hits Polymarket, whose growth pitch has leaned on regulatory arbitrage and crypto-native distribution.
