For the first nine months of 2025, The Trade Desk recorded 20% year-over-year revenue growth, down from 27% growth in the same period of 2024. This slowdown contributed directly to the 67.7% share-price decline over the year, according to S&P Global Market Intelligence data. Investors interpreted the reduced momentum in digital advertising spend on connected television as a sign that The Trade Desk’s expansion into linear and programmatic channels was losing steam relative to previous years.

Two major competitive threats have eroded The Trade Desk’s market position. Amazon has launched its own demand-side platform for streaming television ads and signed agreements with leading video services to expand its inventory. Meanwhile, Google and Meta Platforms have integrated advanced AI targeting tools into their advertising suites, offering advertisers more granular audience segmentation. These developments have siphoned potential ad dollars away from The Trade Desk’s open-internet strategy.

Despite the stock’s dramatic pullback, The Trade Desk remains valued at a trailing price-to-earnings ratio of 43, based on its $439 million net income over the past twelve months and an $18 billion market capitalization. This multiple ranks among the highest in its history and stands well above the broader market average. Given the uncertain competitive landscape and high valuation, many analysts advise caution before deploying fresh capital into The Trade Desk stock.
