Kalshi is trying to turn event outcomes into a regulated financial asset class: its exchange lets people trade yes/no contracts on elections, rates, sports, weather, and more, with prices set by traders rather than a house. The bet has attracted a $1 billion Series G at a $40 billion valuation, while Kalshi says annualized trading volume has surpassed $1 trillion and more than 30 million accounts have been made, funding expansion into indices, perpetual futures, compute markets, institutions, and international markets.
