The OpenAI Connection Gains Credibility
What began as a speculative rumor is looking increasingly substantial. Reports from The Information indicate that The Trade Desk (NASDAQ: TTD) is in early-stage discussions with OpenAI to help sell advertising inventory within ChatGPT . For a company whose stock had been battered by growth concerns, the news landed like a thunderbolt .
The logic is compelling. OpenAI has begun testing ads in its free and lower-tier ChatGPT products, and partnering with an independent demand-side platform (DSP) like The Trade Desk would provide instant access to a vast ecosystem of advertisers without building a complex ad stack from scratch . The Trade Desk’s independence—standing apart from walled gardens like Google and Amazon—makes it an attractive partner for AI platforms seeking open, measurable ad inventory .
CEO Jeff Green’s $148 Million Vote of Confidence
If the OpenAI rumors weren’t enough, co-founder and CEO Jeff Green delivered a stunning vote of confidence. Between March 2 and 4, Green purchased 6 million shares on the open market at prices between $23.49 and $25.08, for a total of approximately $148 million .
Such large-scale insider buying is rare in large-cap tech and sent an unmistakable signal to the market: management believes the stock is significantly undervalued. The timing, coinciding with the OpenAI speculation, created a powerful one-two punch that sent shares soaring over 22% in a single session .
The Bull and Bear Case
The Optimists’ View:
DA Davidson maintained a Buy rating with a $32 price target, arguing that AI assistant ad formats expand The Trade Desk’s long-term total addressable market . If ChatGPT becomes a premium ad surface with high-intent user queries, the revenue potential could be transformative. Analysts estimate OpenAI’s annualized revenue has already surpassed $25 billion, and ads could double consumer-facing revenue to $17 billion . Even capturing a fraction of that through ad-tech fees would be meaningful .
The Skeptics’ View:
Wedbush downgraded the stock to Underperform, arguing the market has overestimated the near-term financial impact. Analyst Alicia Reese projects just $31-77 million in 2026 revenue from any OpenAI partnership—only 1-4% of TTD’s projected base . The firm also warned of long-term structural risks, noting that “as OpenAI matures, we anticipate it will inevitably build a proprietary, in-house DSP,” potentially disintermediating The Trade Desk down the road .
What Comes Next?
The stock’s explosive reaction—on volume more than four times average—suggests large institutional investors are buying the narrative, not just retail traders . But the next leg higher depends on tangible milestones: formal partnership announcements, pilot programs, and ultimately revenue contribution visible in earnings reports .
For now, The Trade Desk sits at an inflection point. The OpenAI discussions, combined with a founder’s nine-figure bet, have transformed a beaten-down growth stock into a story about capturing the next wave of AI-native advertising.
