The Trade Desk Is Up 23.7% and the Debate Is Just Starting

When it comes to putting money where your mouth is, Jeff Green has put ~$148 million of his own money into The Trade Desk (NASDAQ:TTD | TTD Price Prediction) as a personal share purchase. Shares are up 24.43% over the past week, trading at $29.83 as of March 5, 2026. Reddit sentiment on TTD has climbed to 62 out of 100 (Bullish), up from 59 in the early morning hours. The catalyst is real, but the structural questions have not gone away.

The CEO Bet That Has r/stocks Talking

The dominant thread driving TTD discussion comes from r/stocks, where user Tachiiderp posted about Green’s purchase:

“Insider buys usually mark a bottom, but when several CEOs are doing it, is it a sign of desperation?” The post had accumulated 434 upvotes and 79 comments by noon ET. The community is split on what the signal means. TTD is down 55.48% over the past year and 21.96% year-to-date. Three reasons retail investors remain cautiously optimistic:

• Q4 2025 EPS came in at $0.59 against a $0.50 estimate, and adjusted EBITDA margin reached 47%, the highest in recent quarters, demonstrating real operating leverage
• Q1 2026 revenue guidance of $678 million implies only 10.1% year-over-year growth, a sharp deceleration from 14.27% in Q4 and 25% in Q1 2025 , citing AI scale deficits and structural disadvantages versus walled gardens like Google and Meta
• Morningstar cut its fair value estimate from $60 to $35, citing AI scale deficits and structural disadvantages versus walled gardens like Google and Meta

The Trade Desk’s OpenAI Angle Deserves Scrutiny

Reports that The Trade Desk is in early discussions with OpenAI to manage advertising sales for its platforms have added fuel to the rally. Green’s argument is that TTD’s lack of owned inventory makes it the right partner in an AI-mediated advertising world. “The complexity of the global advertising market is not a weakness for The Trade Desk. It is a moat,” he said on the Q4 earnings call. The OpenAI discussions remain unconfirmed, and CPG and auto verticals, which represent over a quarter of TTD’s business, continued to weaken into Q1 2026.

Supply-side peer Magnite (NASDAQ:MGNI) posted net income growth of 535% with a $200 million buyback last week, suggesting real tailwinds across ad tech. Whether The Trade Desk can convert its open-internet thesis into reaccelerating revenue is the question heading into Q1 results.
