Trade Desk stock fell sharply on Wednesday, extending losses from the previous session, after reports that French advertising giant Publicis Groupe advised clients against using the company’s platform following an audit dispute.
The stock dropped 5% on the day, adding to a 7.4% decline on Tuesday, as investor sentiment weakened amid concerns over client retention and potential structural shifts in the digital advertising market.
Publicis audit triggers concerns over business practices
The selloff was driven by a report that a recent audit commissioned by Publicis found The Trade Desk had violated multiple clauses of its agreement, prompting the agency to recommend against the platform.
According to the report, The Trade Desk charged fees exceeding agreed limits and enrolled clients into additional features without their consent.
The Trade Desk, however, pushed back against the claims.
“We’re aware of questions related to a Publicis audit process. Any notion that TTD failed an audit is not true,” the company said.
Separately, CEO Jeff Green also rejected the allegations, stating, “TTD has not ‘failed’ any audit ever.”
The company said it had proposed alternatives to address Publicis’ concerns while continuing to work with the agency.
The dispute highlights tensions between independent ad platforms and large agency groups, particularly around transparency and billing practices.
Analyst downgrades reflect uncertainty over client retention
Following the report, at least two brokerages downgraded The Trade Desk, while several others cut their price targets.
Stifel lowered its rating to “neutral” from “buy,” citing uncertainty around future revenue forecasts.
“We’re not quite sure how conservative current 2026 estimates might be if the company does, in fact, lose some of its client base as a result of this audit,” the brokerage said.
The downgrade reflects growing concerns that the dispute with Publicis could impact The Trade Desk’s ability to retain major clients, particularly if other agencies adopt a similar stance.
Despite the negative developments, some analysts remain more constructive.
RBC Capital reiterated its “Outperform” rating with a $40 price target, pointing to potential resolution and longer-term growth prospects.
Analyst sentiment remains mixed overall.
According to available data, 19 of 38 analysts rate the stock a Buy or higher, while 16 recommend Hold, with expectations of potential upside over the next 12 months.
Competitive pressures and revenue outlook weigh on shares
The Trade Desk is already facing headwinds beyond the audit dispute.
The company’s first-quarter revenue forecast fell short of analyst expectations last month, adding to concerns about slowing growth.
Shares have declined nearly 37% this year, following a steep 68% drop in 2025.
Competition is intensifying from so-called “walled gardens,” including Alphabet’s Google, Meta’s Facebook, and Amazon’s advertising platform, which benefit from integrated ecosystems and access to extensive user data.
Amazon’s platform, in particular, has emerged as a strong competitor due to its access to shopper data, making it increasingly attractive to advertisers.
Rosenblatt Securities analyst Barton Crockett suggested that broader industry dynamics may be shifting.
“We see potential that this could be emblematic of a structural change,” Crockett said.
He added that declining revenues may be pushing advertising agencies toward a more confrontational stance with platforms like The Trade Desk.
Despite the current pressures, The Trade Desk remains a key independent player in the digital advertising ecosystem, offering brands the flexibility to run campaigns across multiple platforms outside of closed ecosystems.
However, the combination of audit-related uncertainty, competitive pressures, and weaker revenue outlook has raised questions about near-term growth and investor confidence.
