Ex-FTX Europe exec launches UpsideOnly to let retail traders share in AI-generated profits

Perpetuals.com, led by former FTX Europe executive Patrick Gruhn, rolled out UpsideOnly, a new AI-powered trading and market prediction platform that allows users to make predictions across equities, crypto, commodities, and forex markets without risking any of their own capital, the firm said Tuesday.

The company deploys its own funds to execute trades based on user-generated signals and shares profits when those trades succeed.

The model is a structural departure from conventional retail trading, where participants collectively lose more than $12 billion annually, the team stated.

On UpsideOnly, users submit directional predictions on global markets but never place actual trades. The platform’s proprietary AI system evaluates each prediction and, when confidence thresholds are met, executes positions using the company’s balance sheet.

If a trade loses or is never placed, the user bears no financial consequences, the company noted.

How the platform works

According to the team, UpsideOnly is built on BayesShield AI, a patent-pending algorithm trained on more than 22 billion executed retail trades, one of the largest behavioral trading datasets ever assembled for model training.

The system combines crowd-sourced human insight with machine-scale pattern recognition to generate trading signals that neither component could produce alone. As users contribute predictions, the algorithm refines its models in real time.

“The dominant retail trading model is not a tool. It is a trap, designed so the platform wins when you lose,” said Gruhn. “Platforms engineered to extract money from the people who could least afford to lose it, sold to them as investing.”

No deposit is required to participate and earn money on the platform, the team said. However, users who place a refundable deposit of $1 or more receive higher payouts, a mechanism designed to deter automated bot activity and encourage more deliberate predictions. The deposit is not used as a trading stake.

Instead, it is held in US Treasury Bills within an external account managed by a separate US-based fiduciary and can be withdrawn at any time, the firm explained.

“UpsideOnly completely changes this broken structure. The user brings the insight, we bring the capital, and we win together. This is what the next generation of financial platforms looks like: humans and AI teaming up on the same side of the table,” Gruhn commented.
