Former FTX executive launches UpsideOnly, an AI trading platform that crowdsources "simulated trading strategies".

Mars Finance reported on May 19th, citing Bloomberg, that Patrick Gruhn, a former executive at FTX's European division, launched the UpsideOnly platform on Tuesday. This platform crowdsources "demo trading strategies" and converts them into shared real-money profits: the system executes trades using only the company's own funds. Investors submit "paper trades" to predict the future prices of assets such as oil, gold, and stocks. An AI model then selects the most likely profitable strategies, which the company executes with its own funds. Once a trade is profitable, the company distributes half of the profits to the trader who provided the valid signal.
