Kalshi, a prediction market that allows people to bet on future events, has raised a massive $1 billion round at a $11 billion valuation, according to a person familiar with the deal. The round comes less than two months after the seven-year-old startup announced its previous fundraise of $300 million at a $5 billion valuation.
The latest round is led by the company’s returning investors Sequoia and CapitalG, the person said. Other investors in Kalshi include Andreessen Horowitz, Paradigm, Anthos Capital, and Neo.
Kalshi and Sequoia declined to comment. CapitalG didn’t respond to our request for comment.
Kalshi’s main rival, Polymarket, was reportedly in talks last month to raise another funding round at a $12 billion to $15 billion valuation, mere weeks after closing a $1 billion round at an $8 billion pre-money valuation, Bloomberg reported.

For the Mamdani versus Cuomo race, Kalshi purchased ad space on New York subway cars, running live screens that displayed the up-to-the-minute odds of each candidate winning, a marketing campaign that undoubtedly raised the company’s brand awareness among New Yorkers.
Kalshi allows people in over 140 countries to bet on various future events, ranging from who Time magazine will name Person of the Year for 2025 and the Rotten Tomatoes score for the film Wicked, to outcomes further in the future, like the next U.S. presidential election winner.
