Kalshi, a prediction market platform, reached a $4 billion annualized run rate, doubling its ARR from $2 billion only two months earlier.

A significant growth catalyst was the engagement generated during the World Cup.

Additionally, Kalshi is reportedly raising funds at a $40 billion valuation, reflecting strong investor confidence in its business model and market potential.

This rapid growth indicates the platform's ability to attract traders and capitalize on global events to drive significant transaction volumes.
