The Trade Desk guides its first revenue decline, 12%, and Netflix ad data goes live without measurement

The Trade Desk▲+0.64% — The Trade Desk, up 0.64 percent today built its business as the buy-side pipe: agencies run self-service campaigns through its platform and the company takes a fee on every advertising dollar that flows. On November 9, after the close, that fee engine reports third-quarter numbers it has already guided down↗ ¹. The floor is at least $650 million against $739.4 million in the same quarter last year, the first guided revenue decline in the company's history, roughly a 12% fall ²⁴.

The slide is not one bad quarter. Second-quarter revenue of $715.06 million grew just 3%↗, missing the $752.41 million consensus, with adjusted earnings of $0.34 against $0.40 expected ². Trailing growth of 11.6% has halved from 23.2%, and each quarter since June 2025 decelerated on the one before it ².

Tariffs, trading down and 500 job cuts

Management blamed autos and consumer-packaged-goods advertisers, about a quarter of the business, cutting budgets over tariffs, and others trading down to cheap media. In September it cut 15% of its workforce, more than 500 people ²⁸. The stock closed November 2 at $12.55, down 75.4% over a year, a $6.1 billion company at 14.1 times trailing earnings ²⁴.

The Netflix door opens without a measuring stick

The untold mechanism is timing. This month, The Trade Desk's Kokai platform starts pointing advertisers' own customer data and third-party segments at Netflix inventory, where programmatic already moves nearly half of non-live ad space across more than 250 million monthly users ³.

The toolkit is broad: over 4 million audience segments and 300 data providers connected ³. But TTD's conversion attribution on Netflix is still in development↗, behind Yahoo DSP, where native measurement already runs ³. Budgets renew on proof, and the proof tool is unfinished. Meanwhile its Mumbai data-partnerships director left for WPP Media in November ⁵.

The bargain case has receipts too

The bulls have numbers, not just hope. Free cash flow hit $136 million in the June quarter, up from $117 million, most of the top 100 accounts still grew double digits as of the August call, and Vanguard filed a 13G showing 22.6 million shares, 5.3% of the class↗, as of September 30 ²⁷. A fallen growth story with cash flow is a different animal from a dying one.

What the print decides

Two questions on November 9: does revenue clear the $650 million floor, and does management show the Netflix▲+0.63% — Netflix, up 0.63 percent today pipe converting spend, not just carrying it ⁸? One competitor already took the crown while TTD stumbled: Reddit's▲+4.29% — Reddit, up 4.29 percent today quarterly revenue of $895 million, up 53%, passed The Trade Desk's↗ for the first time in the September quarter ⁸. The company that was going to unlock the open internet now has to prove it can still bill it.
