Kalshi's Racing to $40 Billion. The Real Number Is 80%.
Prediction markets just repriced again. Second-order thinking says look past the valuation.
Kalshi was worth $11 billion in December. It’s now reportedly raising at $40 billion. That’s not a startup growing up. That’s a market changing its mind about what a regulated exchange is worth, every few weeks.
Here’s what dropped this week. The Information reports Kalshi is in advanced talks to raise at least $750 million at a roughly $40 billion valuation, with Sequoia Capital and Wellington Management in discussions to co-lead. If it closes there, it nearly doubles the $22 billion mark from the $1 billion Series F it did back in May, led by Coatue.
What’s driving it? Revenue. Kalshi’s annualized revenue reportedly topped $4 billion in July, roughly double the $2 billion pace from two months earlier, per The Information. World Cup wagering did a lot of the lifting. For scale, a $40 billion private mark would top Coinbase’s market cap and put Kalshi in the same conversation as Robinhood, which sits around $85 billion. I built prediction markets at Robinhood, so watching this category go from a policy footnote to a $40 billion line item is wild.
Time for a mental model from the book: second-order thinking. First-order thinking stops at the obvious. Revenue doubled, so the valuation doubled, makes sense, next. Second-order thinking asks the follow-up the headline skips: where does that $4 billion actually come from, and how durable is it?
Here’s the second-order read. Sports contracts reportedly make up more than 80% of Kalshi’s trading volume. And those contracts are exactly what more than a dozen states are trying to kill. New York sued. Arizona filed criminal charges. Massachusetts banned the sports markets. Kalshi’s whole defense is that it’s federally regulated by the CFTC, which has told it to keep operating, so states don’t get a vote. That fight isn’t settled.
So the same asset is both the moat and the risk. The regulatory position is why mainstream money will touch this at all. It’s also the single point of failure.
My take: the volume isn’t the product. The rulebook is. In regulated markets, your defensibility and your fragility live in the same place, which is your relationship with the regulator and the law. I see this every day at /mkt, where we run athlete offerings under Reg A+ with tZERO as the trading infrastructure. The compliance structure isn’t overhead. It’s the moat. Get it right and it’s a wall competitors can’t climb. Get it wrong and there’s no business left to value.
The contrarian bit? A $40 billion price on an 80%-sports revenue base isn’t pricing a betting app. It’s pricing a bet that federal preemption holds. That’s the actual trade underneath the trade. None of this is investment advice, and the round hasn’t closed. But if you’re building in a regulated category, steal the lesson: the rules aren’t the thing slowing you down. Long term, they might be the only thing you own.
