Prediction market platform Kalshi has secured $300 million in funding, raising its valuation to $5 billion and enabling plans for expansion into over 140 countries. The company has seen significant growth, surpassing rival Polymarket in weekly transactions, as it capitalizes on the popularity of prediction markets, particularly in sports. Meanwhile, Polymarket is preparing to re-enter the U.S. market after regulatory challenges.

Kalshi has successfully closed a $185 million funding round as it continues to compete in the prediction market space against rival Polymarket, which is reportedly seeking $200 million in its own funding efforts. The investment will help Kalshi expand its platform and services amid growing interest in prediction markets.
