eBay Sues Amazon Over Seller Poaching

Executive Signal Summary

eBay has filed a California lawsuit against Amazon alleging a multi-year scheme to drive eBay sellers away. The court filing claims Amazon repeatedly infiltrated eBay’s internal member email system (M2M) to identify and recruit high-value sellers to Amazon since 2015. Dozens of Amazon sales representatives in the U.S. and abroad supposedly created eBay member accounts to access the M2M system and used it to solicit hundreds of eBay sellers to list on Amazon. The document describes a coordinated, global recruitment effort and notes that the conduct could reach the executive level of Amazon. eBay requests the court stop the practices and award damages for losses incurred. The case underscores intense competition between major marketplaces and could have wide-ranging implications for e-commerce practices if upheld.

FTC Sues Amazon Over Alleged Ad Auction Manipulation

The FTC and 22 state attorneys general have sued Amazon in the Western District of Washington, alleging that its Sponsored Products ad platform secretly used 'soft reserve prices' to inflate advertising costs, converting second-price auctions into de facto first-price ones. The FTC claims this overcharged over 1.2 million advertisers—including 500,000 small businesses—generating over $20 billion in excess revenue from Amazon's $68 billion ad business. By 2024, 80% of winning advertisers paid near their maximum bids, up from 30–40% in 2021. Amazon denies the allegations, asserting that soft reserve prices are standard industry practice, its auctions remain second-price, average winning bids fell 50%, and advertisers saved $8 billion from 2021–2025. The case applies only to Sponsored Products via Amazon Ad Console, not Amazon DSP. Retail media expert Kiri Masters suggests advertiser trust may be damaged but Amazon's ad revenue is unlikely to decline significantly, while competitors could leverage transparency as a differentiator. This landmark case could set precedents for digital ad marketplaces.

California AG: Amazon Pressured Brands to Raise Rival Prices

California Attorney General Rob Bonta says newly unsealed documents from a 2022 antitrust lawsuit show Amazon pressured vendors including Levi Strauss & Co. and Hanes to inflate prices on rival marketplaces. The filings include communications where Amazon flagged lower prices on Target and Walmart listings and vendors sought to have those prices raised; in one example Hanes contacted Target and Walmart to raise prices, and Allergan reported Amazon temporarily suppressed listings until competitors’ prices rose. Bonta's office has asked a San Francisco court for injunctive relief and an independent monitor; the case is scheduled for trial in 2027. Amazon disputes the claims and says it will respond in court. The filings sit alongside prior federal and state antitrust scrutiny of Amazon’s marketplace practices.
