Kalshi has secured a $1 billion Series F funding round at a $22 billion valuation, led by Coatue with participation from prominent firms like Sequoia Capital and Andreessen Horowitz. This significant raise follows an 800% surge in institutional trading volume over the past six months, reflecting growing demand. The company plans to leverage these funds to capitalize on its position as the leader in the U.S. prediction market, which accounts for over 90% of activity.
