When a founder wires $150 million of his own money into a stock that is down 60 to 70 percent, he is not just betting on his company. He is betting on how media will be bought in the future.
Jeff Green’s open market purchase of roughly 6 million Trade Desk shares, about $148 to $150 dollars in personal capital, comes after a brutal derating across adtech and high-multiple software.
The Trade Desk’s revenue is still growing in the teens, but it has clearly slowed, and 2026 guidance landed softer than investors wanted. Add in noisy debates around pricing and competition, plus a market still trying to price what large language models like Claude and ChatGPT mean for incumbent platforms, and the instinctive response has been simple: mark down the stock.
Because, you do not pay peak era valuations for what Wall Street views as yesterday’s model.
Green is betting that the Trade Desk becomes infrastructure
Green is being more contrarian about what comes next. Across the industry, early AI systems are already taking over work that used to require teams, interpreting briefs, ingesting performance data, reallocating budgets, and tweaking campaigns across CTV, open web, and retail media. These AI systems often have faster planning cycles and tighter feedback loops than human-only workflows.
As these automated agents scale, they will still need neutral platforms they can trust for identity, access to quality supply, and reliable performance data.
That is where independent infrastructure like the Trade Desk matters.
It looks less like Green is wagering on a simple rebound in software, and more like a shift toward automated, agent-driven media buying in which the Trade Desk becomes one of the core rails those systems run on.
Green is buying in at a time when the market sees slower growth, tougher competition, and macro uncertainty, because he is wagering that the street is underestimating the Trade Desk’s role in that automated future.
