TLDR
- Omnicom announced a third-party audit of The Trade Desk’s fee structure, sending TTD stock down as much as 9.9% intraday
- An initial internal contract review by Omnicom found no issues; the full audit follows pressure from rival agency Publicis
- Publicis broke with The Trade Desk last week over alleged hidden fees, triggering the broader scrutiny
- A Big Four accounting firm will conduct the deep audit, which could clear TTD or uncover problems
- The Trade Desk CEO Jeff Green has been pushing to work directly with brands, creating friction with agency holding companies
The Trade Desk’s rough year just got rougher. TTD stock fell as much as 9.9% on Monday after Omnicom announced it is commissioning a third-party audit of the platform’s pricing and fee structure.
The move comes just one week after Publicis Groupe made a very public break with The Trade Desk, citing alleged hidden fees. Omnicom is now following suit — though the circumstances are a bit different.
Omnicom’s own initial contract review found no issues whatsoever. The full independent audit appears to be a precautionary response rather than one based on any discovered wrongdoing.
Still, markets didn’t wait for the details. TTD dropped sharply on the news, with the stock sitting around $22.22 as of Monday. That puts the stock down roughly 37% year-to-date, against a 52-week high of $91.45.
Two Agencies, Two Very Different Stories
The contrast between the two agency situations is worth noting. Publicis launched a very public dispute with The Trade Desk last week, framing the relationship as a breakdown over transparency. Omnicom’s tone has been notably calmer.
In correspondence with Ad Age, The Trade Desk described its relationship with Omnicom as going “from strength to strength.” That’s a very different picture from what’s playing out with Publicis.
The full Omnicom audit will be carried out by a Big Four accounting firm. Omnicom’s regular auditor is KPMG, though it’s not confirmed whether KPMG will handle the pricing review specifically.
Playwire CEO Jayson Dubin pushed back on the broader narrative, praising The Trade Desk for pushing the industry toward greater transparency. He described it as a “rising tide lifts all ships” dynamic from the publisher side.
The Trade Desk’s current market cap sits at roughly $11.4 billion, down from much higher levels earlier in the year.
CEO Jeff Green and the Agency Tension
Some of the friction with agency holding companies traces back to CEO Jeff Green’s strategy. Green has been openly pushing to work directly with brands, cutting agencies out of the middle.
He has also called out agencies for their own transparency issues — a move that hasn’t gone down well with the likes of Omnicom and Publicis.
That context matters when weighing how seriously to take the audit announcements. The agencies are not neutral observers; they have a direct interest in the outcome.
The Trade Desk has been reshaping how programmatic ad buying works, which has put it on a collision course with established agency players.
The stock has an average daily trading volume of around 17 million, and that volume has been elevated during recent sessions as the headlines pile up.
The technical sentiment signal on TTD is currently rated as Sell, reflecting the pressure the stock has been under.
The gross margin remains strong at 78.63%, pointing to a business that is still operationally healthy despite the stock’s drop.
The outcome of the Omnicom audit, expected to be thorough given the Big Four involvement, will likely be a key catalyst for the stock in the weeks ahead.
