The Trade Desk is going through it.
The company reported Q1 earnings after the market closed today, posting revenue of $689 million, up 12% year over year and slightly ahead of analyst expectations. However, softer-than-expected guidance sent the stock tumbling more than 15% in after-hours trading.
For Q2, TTD is guiding to at least $750 million in revenue, well below Wall Street expectations of roughly $772 million.
On top of that, the company revealed that its Chief Strategy Officer is leaving for OpenAI. On the bright side, there’s probably some kind of integration in the cards, as she’ll reportedly oversee adtech partnerships there while remaining on TTD’s board.

Why This Matters:
TTD is clearly on the back foot. Beyond perception, the challenges are real: the company’s revenue grew 12% year over year in Q1, one of its slowest growth rates in years, while adjusted EBITDA margins fell from the low‑40s in 2025 to about 30% this quarter.
When you combine that performance with the reality that competition is only intensifying — from Amazon DSP to a growing number of AI-driven buying and optimization platforms — the company suddenly looks far less untouchable than it once did.
Ultimately, TTD has also felt slow to evolve. For years, the company benefited from being the independent DSP leader while much of the market played catch-up. But as AI, automation, curation, and performance-driven media buying reshaped the ecosystem, TTD arguably moved more cautiously than it should have. Only recently has the company more aggressively leaned into AI, for example, and broader platform evolution, and investors may be questioning whether that shift came later than it should have.

Our Take:
Jeff Green previously questioned why more adtech reporters and industry observers weren’t loudly discussing his personal $150 million bet on the company. But moments like this help explain the skepticism. Investors appear less interested in confidence signals right now and more focused on slowing growth, margin pressure, and whether TTD can maintain its position as the market evolves around it.
The company is still enormously important in adtech. But for perhaps the first time in years, it genuinely feels vulnerable.
