Jeff Green Bets Big on The Trade Desk's AI Future
Jeff Green, founder of The Trade Desk, bought roughly 6 million shares—about $148–$150 million of his own capital—in an open‑market purchase after the adtech sector and high‑multiple software names were heavily derated. The Trade Desk’s revenue growth has slowed and its 2026 guidance disappointed some investors, but Green argues the company can become core infrastructure for an automated, AI‑driven media‑buying stack. The article frames early AI agents as taking over planning and budget allocation across CTV, open web and retail media, and says those agents will need neutral platforms for identity, quality supply and reliable performance data. The Trade Desk is positioning around identity and measurement initiatives (UID2, OpenPath, OpenTTD), APIs, and decisioning layers above the bidstream. The purchase produced near‑term paper gains but is presented primarily as a strategic signal about the platform’s future role.
A high‑profile founder investment signals a strategic bet that DSPs can become core infrastructure for AI‑driven automated media buying; this may influence investor sentiment and product/partnership strategies across adtech, but it is not a platform policy change or technical release from a major platform.

Trade Desk CEO Bets Big on Company’s Future with $148M Purchase
The Trade Desk CEO Jeff Green made an open-market purchase of roughly $148 million of the company’s stock between March 2–4, buying shares at about $23–$25 each, according to an SEC Form 4. In a blog post Green framed the buy as a vote of confidence in The Trade Desk’s long-term strategy, citing investments in AI and expansion into new programmatic inventory types such as chatbot placements and sponsored shopping listings. The moves come as the company navigates a shifting ad landscape — agencies including Dentsu and WPP left The Trade Desk’s OpenPath initiative and Amazon has been diverting ad spend to its own DSP. The article also notes The Trade Desk’s Q4 2025 revenue of $847 million (up 14% year‑over‑year) and references Amazon’s $21.3 billion ad revenue in 2025 (22% YoY growth).
The Trade Desk Soars: Vision for Open Internet Takes Shape
The Trade Desk reported Q3 2025 results with revenue of $739 million, up 18% year over year, and net profit of $116 million, up 16% year over year. This marks the second straight quarter meeting earnings estimates since a Q4 2024 miss. CEO Jeff Green emphasized the company’s influence in the open internet, highlighting Unified ID2.0 and OpenRTB fields as industry standards and describing TTD as a key open-data conduit for data vendors and publishers. He argued that large CTV content owners rely on independent partners like TTD and claimed TTD is the single largest source of third-party demand for many publishers, processing about 20 million ad impressions per second. Green outlined a bold vision for a more open internet, suggesting independent DSPs will capture a larger share of spend over time, challenging walled gardens led by Google, Meta, and TikTok.
Fired OpenAI Researchers Dispute Misconduct Claims, Warn of Chilling Effect
Three OpenAI safety researchers, Jasmine Wang, Tomek Korbak, and Mikita Balesni, who were fired last week, have published an open letter denying allegations of mishandling sensitive information. They warn that their dismissal creates a chilling effect that stifles AI safety work and open dialogue within the company. The researchers say they acted in good faith and within company norms, and that the reasons for their firing are unclear. They urge OpenAI to uphold its commitments to third-party safety auditors and maintain a transparent culture. OpenAI responded with an internal memo denying retaliation and stating that employees are not terminated for raising concerns, but did not address specific policy violations or circumstances of the dismissal. The dispute highlights tensions between internal safety research and company communication policies at a time when OpenAI faces scrutiny over safety incidents.
