Citizens downgraded Trade Desk from Market Outperform to Market Perform, citing rising competition from Amazon. Generative AI has lowered switching costs, eroding the platform’s historical edge. Amazon’s access to the largest retail media data set now offers tighter ad targeting and closed‑loop measurement, squeezing Trade Desk’s take‑rate upside for investors.

Open‑web ad spend, excluding connected TV and audio, slows as walled gardens capture more budget. Citizens warns that AI‑driven search and ad‑overviews pressure publisher traffic, dampening impression growth. Amazon’s lower fees and the upcoming Audience Unlimited tiered pricing could further erode Trade Desk’s margins by 2026 for the broader market view.

Trade Desk trades at roughly 11.2× 2027 EBITDA, matching peers. With limited near‑term catalysts, Citizens sees a balanced risk‑reward profile. Investors should monitor Amazon’s fee strategy, the 2025 launch of Audience Unlimited, and any shifts in open‑web spend that could alter the competitive balance in programmatic advertising for the industry.
