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.

The NHL has entered into multiyear deals with prediction market platforms Kalshi and Polymarket, marking a significant move in the sports betting landscape as these markets gain traction. Unlike traditional sportsbooks, these platforms operate legally in all 50 states, and the NHL aims to ensure game integrity through this partnership, despite concerns from industry groups about the legality and implications of such markets.

Polymarket is exploring a financing round that could value the company between $9 billion and $10 billion, while Kalshi is nearing a $5 billion valuation for its upcoming fundraising. Both prediction market platforms are experiencing increased activity, with Polymarket set to relaunch in the U.S. after receiving approval from the CFTC.

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.

Kalshi has significantly outperformed Polymarket in the prediction market sector, capturing 62% of the total trading volume in the U.S. from September 11 to 17, with over $500 million in weekly trading volume. While Polymarket has made moves to re-enter the U.S. market by acquiring QCX and launching new markets, Kalshi's faster trading pace indicates a stronger current user engagement.
