TTD vs. AMZN: Which Ad-Tech Stock Is the Smarter Pick Now?

Zacks compares Amazon (AMZN.OQ) and The Trade Desk as beneficiaries of rising digital advertising and CTV momentum, concluding Amazon is the smarter pick today. Amazon’s ad business generated $21.3B in Q4 2025 (up 22% YoY), driven by full‑funnel DSP capabilities, AI tools and expanding Prime Video ad inventory. The Trade Desk benefits from CTV, retail media and its Kokai AI DSP, but faces softer demand in key verticals, higher execution risk and intense competition from walled gardens. AMZN’s diversified revenue base (retail, AWS, advertising) and large cash balance provide scale advantages. Valuation and recent performance contrast: AMZN has outperformed over the past month and trades at a higher forward P/E versus TTD, supporting Zacks’ view favoring Amazon for risk‑adjusted exposure to ad‑tech growth.
