The Trade Desk vs. Amazon: Which Ad-Tech Stock Is the Smarter Pick?

Amazon and The Trade Desk are increasingly competing in the rapidly expanding digital advertising and connected TV (CTV) ecosystem. While Trade Desk faces revenue growth deceleration due to macroeconomic softness across consumer-packaged goods and automotive verticals, Amazon continues to show robust operational strength. In the second quarter of 2026, Amazon reported a 26% year-over-year surge in advertising revenues to $19.8 billion, driven primarily by Sponsored Products and expanding Prime Video ad inventory. Amazon's overall financial performance remains solid, with total quarterly revenues rising 20% to $200.6 billion and operating income growing 43% to $27.5 billion. Its cloud computing unit, AWS, accelerated 36.7% to $42.2 billion in revenue. Furthermore, consensus earnings estimates for Amazon have been revised upward by 46.4% over the past 60 days. Although Amazon plans approximately $220 billion in capital expenditures for 2026 to support AI and AWS infrastructure—potentially pressuring short-term free cash flow—its diversified revenue streams and retail media scale position it favorably in the ad-tech market.
