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

The Trade Desk and Amazon are both major players in the digital advertising space, but they have different business models and growth prospects.

The global digital advertising market is expected to grow at a CAGR of 13.2% from 2026 to 2035, according to Precedence Research.

The Trade Desk operates a pure-play demand-side platform that helps advertisers focus on data-driven ads, while Amazon's advertising business has emerged as a strong contender in the digital advertising space, leveraging its first-party data.

The Trade Desk faces challenges from intense competition and slowing revenue growth, but it also has several encouraging trends that could drive long-term growth prospects, including increasing digital spending in CTV and retail media.

Amazon's advertising business is growing rapidly, with revenues jumping 26% year over year to $19.8 billion in the second quarter of 2026, and its position in CTV and premium video advertising is strengthening.
