The Trade Desk Posts $736M Quarter as Revenue Stalls for First Time

The Trade Desk cleared Wall Street's low bar in Q3 2026, but just barely: revenue came in at $736 million, down 0.5% year-over-year — the company's first stalled quarter after posting 18% growth in the same period a year earlier. Political ad spending, boosted by the midterms, kept the number from slipping further.

CEO Jeff Green opened the earnings call on a personal note, welcoming back co-founder Dave Pickles, whose expanded role ADWEEK reported the week before. From there, the story turned to numbers — and most of them point down.

Adjusted EBITDA fell to $266 million, a 36% margin, versus $317 million and a 43% margin a year earlier. Net income collapsed to $38 million from $116 million, a figure that includes $44 million in restructuring charges, primarily severance. That severance bill has a cause: The Trade Desk cut 15% of its workforce during the quarter.

For the first nine months of 2026, revenue reached $2.14 billion, up 4% year-over-year. The company guided to $755 million for Q4.

What does this change for marketing buyers?

Two developments on the call matter directly to brands and agencies working with the demand-side platform (the software marketers use to buy digital ad inventory programmatically).

First, the cost of running campaigns through The Trade Desk should keep falling — through layoffs, if not through technology. The company expects the 15% workforce reduction to generate more than $100 million in savings during 2027.

Second, and more concretely, the company's Koa AI model — the machine-learning layer that optimizes bids and targeting inside the platform — delivered measurable results during the quarter. Across 62 A/B tested campaigns (side-by-side trials comparing AI-assisted buying against standard workflows), Koa improved median cost per acquisition by 21%.

It also cut campaign setup time by up to 15%, according to figures shared on the call.

For a marketing leader, a 21% improvement in acquisition cost is not a rounding error. It's the difference between a channel that scales and one that gets cut in the next budget review. And The Trade Desk clearly wants buyers to hear that message as it defends its position in a consolidating programmatic market.

The political cushion

Green called the 2026 elections The Trade Desk's "biggest political cycle yet," a striking claim for a midterm rather than a presidential year. That spending cushioned the quarter's results — without it, the 0.5% decline would have looked considerably worse.

The framing matters beyond one quarter. Political dollars are cyclical, and 2027 won't have an election to lean on. A company that grew 18% a year ago and now shrinks slightly, even with a favorable political tailwind, faces a simple question: where does growth come from next?

The company's answer appears to rest on three legs: cost discipline through restructuring, AI-driven performance improvements like Koa's, and the return of trusted leadership, with Pickles back in an expanded role alongside Green.

The margin story

Margins tell the tighter version of the quarter's story. A drop from 43% to 36% in adjusted EBITDA margin, paired with net income falling by two-thirds, shows a company spending heavily while revenue plateaus. The $44 million in restructuring charges explains part of the net-income hit — but not the margin compression, which reflects the underlying cost base the layoffs are meant to fix.

Investors seemed to accept the trade-off. The results cleared the low expectations Wall Street had set heading into the report, and the Q4 guidance of $755 million implies at least a stabilization attempt before year-end.

For marketing-leadership readers, the practical read is this: The Trade Desk is getting cheaper to run campaigns on, both because its AI is genuinely improving acquisition economics and because the company is cutting its own costs aggressively. Whether that's enough to reignite growth absent election spending — that's the question 2027 will answer.
