Jasjeet Sekhon spent eight years building the machine-learning infrastructure behind the world’s largest hedge fund. Now he’s taking what he learned to Google DeepMind.

Bridgewater Associates confirmed that Sekhon, its chief scientist and head of AI, will leave to become DeepMind’s chief strategy officer — an appointment founder Demis Hassabis announced via LinkedIn on Wednesday. As a parting gesture, Bridgewater offered him a board seat.

What Bridgewater Is Losing

Sekhon joined Bridgewater in 2018 as head of machine learning and rose to chief scientist, where he built AIA Labs — the firm’s dedicated AI research unit operating under Co-CIO Greg Jensen. His specialty is causal inference in low signal-to-noise environments, exactly the kind of problem that defines both quantitative finance and frontier AI research. His methods are already embedded in ML platforms at Amazon, Google, Microsoft, and Netflix, according to Bridgewater’s own website.

He held no investing responsibilities. His job was pure research infrastructure — which makes the departure sting differently. Bridgewater isn’t losing a portfolio manager. It’s losing the architect of its AI future.

The Talent Migration Pattern

Sekhon’s exit fits a widening trend: quantitative finance keeps training world-class ML talent, and AI labs keep poaching it. The compensation math has shifted. Bridgewater expanded employee equity to over 60 percent of staff in 2026, a retention play that came too late for its chief scientist.

DeepMind, meanwhile, gets a strategist who spent years applying machine intelligence to noisy real-world data — a rare skill set at the intersection of academic rigor and industrial scale.

For Bridgewater, the board seat is a diplomatic touch. But when your top scientist leaves for the other side of the talent war, diplomacy is what you offer when you’ve already lost the argument.
