What Changed For Trade Desk Stock, And What Did Not?
Trade Desk (TTD) shares fell 76.3% in the year to October 13, 2026, while the S&P 500 returned about 18%. The advertising technology company reported slower revenue growth in each of the past four quarters. In the August 6, 2026 report, growth had fallen short of management’s own expectations. How far did Trade Desk’s growth fall, and what reasons did management give?

Trade Desk Blamed The Economy And Itself
Revenue at Trade Desk grew 17.7% from a year earlier in the third quarter of 2025. By the second quarter of 2026, that expansion had slowed to just 3.0%. During the August 6 call, management pointed to two factors behind the miss. Executives said economic conditions had made it harder for some of the world’s largest brands to grow, and they acknowledged that Trade Desk had not executed as well as it could have.
Part of the decline occurred in August. The Motley Fool linked the stock’s 24% loss that month to the second-quarter report missing estimates and the analyst downgrades that followed. Trade Desk’s peers didn’t share the slump: Alphabet stock, for one, rose about 50% over the same twelve months.
Where Is Trade Desk Losing Growth?
The current slowdown centers on some of Trade Desk’s largest advertisers. For the year to date, advertisers outside the top 500 had grown over 50% year over year, according to management. Executives also pointed to cyclical pressure on two specific groups of advertisers: consumer goods makers and carmakers. These two categories generate around 25% of the company’s business. Even so, about half of those advertisers were still growing very well with Trade Desk.
In August, management assumed no meaningful improvement in conditions for the third quarter of 2026, with results for that period still to come. The company guided revenue for that quarter to at least $650 million. This compares to $715 million in the second quarter and about $739 million a year earlier. That guidance implies revenue about 12% lower than in the same quarter of 2025, which would be Trade Desk’s first year-over-year quarterly decline in at least three years.
What Has And Has Not Changed At Trade Desk?
Bottom-line profit has slipped. Over the past twelve months, Trade Desk’s net margin was 13.6%, down from 15.6% a year before. In August, management guided to less profit for the third quarter. Adjusted EBITDA, a profit measure that leaves out several costs, was guided to about $160 million. The company reported $241 million for this metric in the second quarter.
Yet Trade Desk still sells more than it did a year ago. Revenue over the same twelve months was $3.0 billion, an increase from $2.7 billion a year earlier. The company also holds more cash than debt, maintaining net cash of $1.1 billion. Revenue remains the measure to watch when Trade Desk reports its third quarter of 2026.
