The Trade Desk, Inc. (US88339J1051) closed at USD 13.92 on Nasdaq on September 18, 2026, down 2.4 percent from the previous session. The move followed the company’s removal from the S&P 500, while second-quarter revenue growth of 3 percent to USD 715 million had already raised questions about the advertising platform’s near-term pace.

Index removal adds selling pressure

According to Ad-hoc-news on September 21, 2026, index funds sold an estimated USD 680 million of shares linked to the S&P 500 change. The same report placed The Trade Desk market capitalization at about USD 6.6 billion as of September 18, 2026, far below its roughly USD 65 billion peak in December 2024.

The index change is therefore more than a technical label. A smaller market capitalization reduces the pool of passive funds required to hold the stock, while the 90 percent decline from the December 2024 peak shows how sharply the market has repriced the company over that period.

Q2 growth missed expectations

The Trade Desk generated USD 715 million of revenue in the second quarter of 2026, up 3 percent year over year, according to TIKR on September 22, 2026. The figure was below the approximately USD 751 million expected by analysts, while adjusted earnings per share of USD 0.34 missed the USD 0.40 estimate.

Management guided third-quarter 2026 revenue to at least USD 650 million, a level that implies an approximately 12 percent decline from the prior-year quarter, according to Yahoo Finance on September 21, 2026. That guidance makes the November report the next concrete test of whether cost reductions can protect profitability while revenue contracts.

Targets remain close to market price

On September 18, 2026, Guggenheim raised its price target to USD 13 from USD 12 and kept a Neutral rating, according to TIKR. The target remains below the September 18 closing price of USD 13.92, while the Street mean target was reported near USD 13.60, also below that close.

The principal counter-factor is the company’s planned workforce reduction. About 575 roles, or roughly 15 percent of staff, were affected in September 2026, with charges of USD 39 million to USD 51 million expected in the third quarter, according to TIKR. The savings may support margins, but the restructuring also highlights the pressure created by slower advertising demand and competition from vertically integrated platforms.

November report sets next checkpoint

The third-quarter 2026 report is due on November 5, 2026, and management’s USD 650 million revenue guide provides the clearest numerical checkpoint for the stock. Until then, the gap between the USD 715 million second-quarter result and the USD 650 million third-quarter guide keeps revenue direction and adjusted EBITDA at the center of the valuation debate.

The Trade Desk stock closed at USD 13.92 on Nasdaq on September 18, 2026, down 2.4 percent on the day. The reported market capitalization was USD 6.60 billion at that snapshot.
