Perpetuals.com has launched UpsideOnly, a trading product led by former FTX Europe executive Patrick Gruhn that is aimed at giving retail users access to profits generated by an AI-driven model without committing upfront client capital. According to the company, BayesShield AI was trained on 22 billion historical trades, selects simulated trading strategies, and the platform shares 50% of profits with users. Gruhn said he has committed $100 million and is seeking several hundred million dollars for proprietary trading. The launch is framed as a lower-risk, broader-access model for non-institutional participants, though the available information does not specify launch jurisdiction, supported assets, regulatory structure, or detailed profit-allocation mechanics beyond the 50% share.
