Hyperliquid has announced its entry into the prediction market, dominated by Polymarket, by introducing a 'zero-fee' card. According to CoinDesk, Hyperliquid has unveiled a groundbreaking fee structure for its 'outcome tokens,' which allow users to trade the results of real-world events. Users pay no fees when they start betting. With the implementation of the HIP-4 upgrade, Hyperliquid users will be able to trade Bitcoin futures from a single wallet and simultaneously bet on real-world events such as US presidential election results or sports matches.
