Kalshi, the prediction market platform, has raised $1 billion in a funding round valuing the company at $22 billion. Led by Coatue Management, this marks the company's third investment in seven months, with each round roughly doubling Kalshi's valuation. The previous funding made founders Tarek Mansour and Luana Lopes Lara billionaires on paper, reflecting intense investor interest despite regulatory scrutiny.

The platform has experienced explosive growth, with annualized trading volume reaching $178 billion, more than tripling in six months. Kalshi claims about two million monthly users and generates annualized revenue exceeding $1.5 billion. The company is now shifting focus to institutional investors, with trading volume from financial firms growing 800% recently.

Despite its momentum, Kalshi faces regulatory challenges and competition from rivals like Polymarket, Interactive Brokers, and DraftKings. The company scored a legal victory when a federal judge blocked Arizona from prosecuting it under state gambling laws. Founder Tarek Mansour views competition positively, stating it "enables growth for everybody" as prediction markets gain mainstream acceptance.
