Kalshi secures $1B in fresh funding as valuation jumps to $11B

Kalshi has raised another $1 billion, lifting the prediction-market platform to an $11 billion valuation.

Summary

• Kalshi raised $1 billion, lifting its valuation to $11 billion.
• The company is growing fast with new data, custody, and product partnerships.
• It faces fresh state-level legal pressure even after winning federal approval.

The raise comes less than two months after the startup secured $300 million at a $5 billion valuation, marking one of the fastest valuation jumps in the sector this year.

Details of the latest finding round were shared on a Nov. 20 TechCrunch report, citing a person familiar with the deal.

A rapid-fire funding streak

The new round is led by returning backers Sequoia and CapitalG, the same investors who anchored Kalshi’s previous raise. Other long-time supporters include Andreessen Horowitz, Paradigm, Anthos Capital, and Neo. None of the firms commented on the new raise.

The timing places Kalshi in the middle of a growing rivalry with Polymarket, which has reportedly been exploring a new raise at a valuation between $12 billion and $15 billion, only weeks after securing $1 billion at an $8 billion pre-money valuation. 

Both platforms have seen a rapid rise in activity this year, helped by markets tied to political outcomes, especially the U.S. presidential election. Their public visibility increased even more after correctly predicting the result of New York City’s recent mayoral race. 

A fast-growing market with legal hurdles

Kalshi now serves users in more than 140 countries, offering markets on everything from Time’s 2025 Person of the Year to film ratings and long-term political outcomes. In October, the company reached $50 billion in annualized trading volume, a huge jump from the roughly $300 million handled last year.

Kalshi won a major case against the Commodity Futures Trading Commission last year, allowing Americans to trade on its platform. However, it remains in disputes with several state regulators who claim its markets amount to illegal gambling.

One of the most pressing challenges is in Massachusetts, where the Attorney General has asked a court to block Kalshi’s sports markets. Kalshi says that such an order could force the liquidation of $650 million in open positions, disrupting the entire exchange while the case moves forward.

Polymarket, meanwhile, has been barred from serving U.S. users since 2022 following a settlement with the CFTC, though it reentered the regulatory process by acquiring a derivatives exchange and a clearinghouse.

Kalshi’s expanding institutional partnerships

The company has also made several moves in November to expand its reach. Kalshi has begun integrating its prediction data directly into Barchart’s platforms, which serve millions of retail investors and a wide range of institutions. 

It has also introduced new markets tied to sneaker and collectible prices through a partnership with StockX, turning highly watched product releases into tradable events.

And earlier in the month, Kalshi shifted all USD Coin (USDC) custody and payouts to Coinbase’s institutional system, strengthening security and compliance for its users.

Kalshi’s latest raise suggests that investors see the sector moving rapidly toward mainstream adoption, even as regulators continue to debate where these platforms fit within existing laws.
