Kalshi in talks with Sequoia, Wellington for $750 million fund raise at $40 billion valuation

Kalshi, which raised $1 billion in May at a $22 billion valuation, is now the number one prediction market platform by revenue, followed by Polymarket, which was last reported to be seeking funding at $20 billion, following a $600 million investment from the Intercontinental Exchange, the owner of the New York Stock Exchange, at a $15 billion valuation in August.

Kalshi’s annualized revenue increased to $4 billion in July, bolstered mostly by 2026 World Cup betting. Polymarket's revenue was only $1.1 billion for that same period. Sequoia Capital recently said Kalshi “now claims 95% U.S. market share in prediction markets.”

Most of Kalshi’s revenue comes from sports contracts, which contribute to over 80% of its volume. Kalshi announced Wednesday that Jeff Bandman, the lawyer who helped Kalshi secure a license to be a CFTC-regulated exchange in 2020, is returning to Kalshi as CEO of Kalshi Prime, which serves customers of Kalshi’s margin perpetual futures business.

Neither Sequoia, Wellington nor Kalshi immediately responded to a CoinDesk request for confirmation.
