Ex-DeepMind poker AI researchers raise Series A at over 500 million dollar valuation for trading agents

This is a neat example of research talent migrating from game-playing AI straight into markets, since the same reinforcement learning tricks that beat professional poker players apparently generalize to reading order books. A European fund making its largest ever bet on a Prague based lab also pushes back on the idea that frontier AI talent only clusters in the Bay Area. Worth watching whether regulators start paying closer attention as more trading volume gets handed to autonomous agents with no track record beyond a poker table.
