AI stock trading startup EquiLibre raises funding at a $500M+ valuation
Summary
Prague-based AI developer EquiLibre Technologies Inc. secured Series A funding at a valuation exceeding \$500 million, led by Stockholm-based Creandum, which made its largest-ever investment. Turing Prize laureate Richard Sutton, a pioneer in reinforcement learning, also invested and advises the company. EquiLibre, founded by the creators of the DeepStack poker AI, develops AI agents for financial trading, launched in 2025. These agents initially focused on cryptocurrencies before expanding to traditional stock markets like the Nasdaq, now executing billions of dollars in trades monthly without reporting a losing month. The company's technology utilizes self-play, a training method where AI learns by playing against itself, which is particularly effective for imperfect-information scenarios common in both poker and financial markets. Proceeds will expand its computing cluster and hire deep learning researchers.
Key takeaway
For investors evaluating AI-driven financial platforms, EquiLibre's successful Series A funding at a $500M+ valuation, backed by Creandum and reinforcement learning pioneer Richard Sutton, signals strong market validation. Your due diligence should consider the proven efficacy of self-play AI in imperfect-information environments like trading, as demonstrated by EquiLibre's reported zero losing months since 2025. This suggests a robust, scalable approach to automated trading that warrants closer examination for potential portfolio diversification.
