Auctions in the Crosshairs: Google and Amazon Face Scrutiny
Two major developments in ad tech antitrust enforcement occurred last week. A judge ruled that Google will not be forced to spin off its ad tech business despite a prior monopoly ruling, instead opting for behavioral remedies. Meanwhile, the FTC filed a lawsuit against Amazon, alleging its ad auctions for SMB advertisers involved a 'shadow participant' that inflated prices. The article discusses the implications for auction transparency and fairness in the ad tech industry, noting that while Google's case resulted in remedies like higher floors for certain buyers and more data sharing, the FTC's case against Amazon has more limited possible penalties.
Major platform antitrust rulings and lawsuits directly impact auction transparency and pricing dynamics across the ad tech ecosystem.

FTC Amazon Case Highlights Opacity in Ad Auctions
The FTC's lawsuit against Amazon's on-platform search advertising business has drawn attention to the lack of transparency in digital ad auctions. Agency executives note that advertisers are not panicking, as opaque auction dynamics have become common across platforms like Meta and Google. Amazon's shift away from second-price auctions and its use of 'soft reserve' pricing are central to the FTC's case, but advertisers are accustomed to such practices. The article discusses how platforms increasingly control auction mechanics, leaving advertisers with limited levers and a focus on performance outcomes rather than auction fairness. Google's recent bidding updates further centralize control, while Meta pushes creative optimization. The piece underscores the industry's acceptance of these dynamics, prioritizing results over transparency.
FTC Amazon Ad Tech Case Lessons from Google Ruling
The article discusses the implications of the recent antitrust rulings for the FTC's lawsuit against Amazon over its ad auction practices. The FTC sued Amazon on August 31, 2026, alleging hidden 'soft reserve prices' that overcharged advertisers for over seven years. On September 2, Judge Leonie Brinkema ruled in the DOJ's case against Google's ad tech, opting for behavioral remedies instead of a breakup. Industry leaders, including Arnaud Créput of Equativ, James Avery of Kevel, and Adam Heimlich of Chalice AI, offer their perspectives on the lessons for the FTC. Créput warns that behavioral remedies may not fix structural conflicts, citing France's 2021 fine of Google that failed to change market structure. Avery emphasizes the balance between proving harm and implementing fixes. Heimlich argues for strong enforcement to prevent future abuses.
Google Wins No Breakup; Amazon Faces FTC Ad Lawsuit
In a week of antitrust news, federal judge Leonie Brinkema ruled that Google will not be forced to break up its ad tech business, despite an earlier ruling that it operates a monopoly in the supply-side platform and ad server markets. Separately, Amazon faces a lawsuit from the FTC and 22 state attorneys general alleging that its 'soft reserve price' tactic in Sponsored Product auctions forced advertisers to pay billions more than necessary, netting the company an estimated $20 billion since 2019. The outcome for both platforms remains uncertain, but the cases highlight growing regulatory scrutiny and expectations for transparency and fairness from Big Tech. The podcast also touched on OpenAI's revenue announcement and The Trade Desk's Kokai Zuma update, signaling continued investment in agentic AI.
