The Trade Desk, which runs a self-service platform where ad agencies buy display, video, audio and connected-television inventory across the open web, spent its August earnings call explaining a market rather than a company. Roughly a quarter of the spending on its platform comes from consumer-goods and automotive advertisers, and those advertisers are pulling back: carmakers and retailers are both cutting budgets as tariffs squeeze margins. Management added that some large brands had moved to cheaper programmatic-guaranteed buying instead of paying for premium decisioning, and acknowledged execution gaps of its own. Second-quarter revenue grew 3.0% to $715.1m. The third quarter was guided to at least $650m — about a 12% fall from a year earlier, and some 19% below what analysts expected.

Three smaller companies selling into the same marketing budget reported the opposite quarter.

The quarter the challengers had

Viant Technology, an independent buying platform worth $847m — roughly a seventh of The Trade Desk — grew second-quarter revenue 33.9% to $104.3m, with customer spending on connected TV up about half. Its Direct Access product, which buys inventory straight from publishers rather than through exchanges, went from about 50% of connected-TV spending on the platform to more than 80%, and Viant says the route cut the cost per thousand impressions by 35%. Management said friction between agencies and its largest competitor was pushing budgets its way.

The more telling number sits elsewhere in Viant's disclosure. Outcomes, an autonomous buying tool launched six months ago and positioned explicitly against Google's Performance Max and Meta's Advantage+, already accounts for 5% of all advertising spend on the platform. Model-native buying is taking share inside the open internet, not only outside it.

Digital Turbine, which places apps and in-app advertising directly onto Android handsets through carrier and manufacturer deals, grew fiscal first-quarter revenue 26.8% to $166.0m. Gross margin improved to 49.4% from 47.3%, full-year guidance went up to $650m-$670m, and net leverage fell to 2.5x from above 5.0x. Its account of where the money is going is blunt: open-web traffic is down roughly 10% year on year as AI answers displace clicks, with some categories off 20% to 40%, while app releases grew 60% and the average person now spends about five hours a day inside apps.

Zeta Global, a marketing cloud that predicts consumer intent from opted-in identity data, grew revenue 43.5% to $442.8m — 28% of that organic — at a 59.1% gross margin, and raised full-year guidance to $1.818bn. It is the group's follower rather than its argument: Zeta sells software into marketing departments and makes no autonomous-bidding claim, and its growth suggests marketing budgets are being redirected rather than cancelled.

What The Trade Desk still has

The deceleration is not one bad quarter. Revenue growth ran 17.7%, then 14.3%, then 11.8%, then 3.0% across four quarters, and second-quarter operating income of $101.6m was 13% lower than a year earlier. Customer retention is not the problem — it has stayed above 95% for more than a decade — but revenue per retained customer is. Connected TV still grows double digits and is now more than half of revenue; audio has been the fastest-growing channel for four straight quarters; joint business plans with large advertisers rose 38%.

The pressure is on price. The Trade Desk's take rate has sat between 19% and 21% since 2017, and Amazon's demand-side platform charges nothing on its own inventory and about 1% on some streaming deals. Where the reallocated dollars land is visible in the largest sellers' results: Amazon's advertising segment grew 26% to $19.8bn and Meta's grew 27% to $59.4bn in the same quarter, against a forecast 5.0% for total ad spending in 2026. Five times the market is not a cycle.

The price

The Trade Desk's 15.7x trailing earnings looks cheap and is an artifact: the forward multiple is higher, at 32.8x, because consensus has 2026 earnings per share at $0.40 against $0.91 last year, and 2027 lower again at $0.24. Price paid per dollar of trailing gross profit has fallen from about 5.3x in February to 2.50x, and free cash flow now runs at 13.9% of the market value. Among the challengers, Digital Turbine trades at 16.7x forward earnings — its trailing figure is negative — and Zeta at 29.2x forward, or 7.3x trailing gross profit.

The shares have followed the results. The Trade Desk's 50-day average has sat below its 200-day since 13 November 2025, an unbroken nine-month downtrend, and the stock lost 21.9% on 7 August on nine times its normal volume. Over the past month Zeta rose 38.9%, Digital Turbine 25.4% and Viant 11.0%, while Criteo fell 17.0% — advertising technology is sorting by result, not moving as a block. Two apparent gainers in the group are not re-ratings at all: Semrush is frozen at $12.00 after Adobe's cash takeout closed in April, and DoubleVerify, an ad-verification business that grew 2.5% last quarter, jumped because Nielsen agreed on 6 August to buy it for $13.60 a share.

The setup

Where it stands — The Trade Desk guides to its first revenue decline while three smaller platforms selling the same budget grew 27% to 44%. Would confirm — Viant's third-quarter revenue growth holds above 25% while The Trade Desk lands at or below its $650m guide. Would invalidate — The Trade Desk returning to double-digit growth in the fourth quarter with consumer-goods and auto spending recovering. Watch next — Third-quarter results in early November from The Trade Desk, Viant, Zeta and Digital Turbine. Valuation — The Trade Desk: 15.7x trailing earnings but 32.8x forward; 2.50x trailing gross profit against 5.3x in February.
