42AI exits stealth with $62.5M to predict how traders act in volatile markets
What's the deal? Israeli startup 42AIDealroom has a profile for this one. Try Dealroom → has come out of stealth with a $62.5 million seed round from its founders and Infinity GroupDealroom has a profile for this one. Try Dealroom →, accumulated over three years. The Tel Aviv company is building a "behavioral world model" that estimates the odds of how individual traders will respond when markets turn volatile.
What's the endgame? 42AI says its model tries to measure people's underlying psychological tendencies rather than extrapolate from past actions. It feeds data points — from know-your-customer checks to call frequency and voice sentiment — into a transformer-based world model that assigns probabilities to possible decisions.
How it works: A brokerage can see what each client is likely to trade over the next 24 hours, including instrument, direction, and volume. If clients look set to pile into the same trade, a risk desk can hedge before the exposure lands on its book.
The traction: 42AI says 10 brokerages use the product, charging a flat fee or a cut of the value generated. Revenue has reached seven figures, and one brokerage gained about $30 million in extra value through dynamic hedging, chief executive officer Amit Gal-Or said.
Why now? The company spent three years building the model, combining psychology, neuroscience, and genetics research. Its training data started with thousands of psychological assessments, grew past 2 million people via government and biobank datasets, and now spans about 30 million.
What could go wrong? Key figures are company-reported. 42AI claims 98% accuracy on trades, but Gal-Or clarified that this measures whether trading flows fall within a predicted range, not whether each trade was predicted correctly. The test is whether the forecasts hold up under outside scrutiny.
The signal: At $62.5 million, the round sits in the top percentile of all-time seed deals for enterprise software in Israel. 42AI enters a newly well-funded niche: behavior-modeling startups Simile and Aaru raised $200 million and $88 million, while Humans& announced a $480 million seed round. Unlike those broader pitches, 42AI's immediate bet is narrow — brokerage risk management — and whether its "predict human behavior" claim travels beyond finance remains unproven.
