Vitalik Buterin, co-founder of Ethereum, criticised structural flaws in prediction markets and described how he profited by betting against irrational crowd sentiment. He warned that prediction markets are turning into gambling-like products and urged a shift toward hedging strategies. Buterin said he made about a 16 percent return by placing roughly $440,000 in bets on Polymarket and earning $70,000. He also outlined a hedging-based finance model that could ultimately replace fiat money.

South Korea is overhauling administrative rules governing government research funds to widen individual researchers’ discretion and reduce paperwork. The Ministry of Science and ICT said the Cabinet approved an amendment to the enforcement decree of the National Research and Development Innovation Act.

Overhead spending rules will shift to a negative list, and pre-approval requirements for meeting expenses will be abolished.
