Prediction market platform Kalshi has achieved a $22 billion valuation following a $1 billion Series F funding round led by Coatue Management, with participation from Andreessen Horowitz, Sequoia Capital, Morgan Stanley, and Ark Invest. This funding round has doubled Kalshi's valuation in just five months, reflecting strong confidence from Wall Street and Silicon Valley in regulated prediction markets. Kalshi's annualized revenue has surpassed $1.5 billion, and it, along with Polymarket, accounted for most of the $25 billion traded in prediction markets last month. Despite its rapid growth, Kalshi faces significant legal challenges, with 19 federal lawsuits questioning the legality of its contracts, which some authorities liken to unlicensed gambling. The company has responded by hiring Stephanie Cutter, a former Obama administration official, as a policy adviser to navigate the increasing regulatory scrutiny. Kalshi's trajectory mirrors that of other fintech firms like Coinbase and Robinhood, which have thrived amid regulatory uncertainty, raising questions about whether institutional support can ultimately overcome legal hurdles.
