GameStop’s May 2026 unsolicited $55.5 billion cash-and-stock bid for eBay was swiftly rejected by the target’s board as neither credible nor attractive, citing financing uncertainties, governance risks, and leverage concerns given GameStop’s roughly $12 billion market capitalization versus eBay’s larger scale. The much smaller acquirer’s reliance on a $20 billion TD Securities commitment letter and its own $9.4 billion cash reserves raised doubts about deliverability, while eBay has emphasized its standalone growth trajectory and capital returns. GameStop’s subsequent accumulation of a nearly 10% stake and Ryan Cohen’s personal purchases signal activist pressure rather than a completed transaction. With no binding agreement or regulatory approvals secured months later, trader consensus prices in near-certain failure. Tail risks include an escalated proxy contest or unexpected partnership, though both face substantial structural and shareholder hurdles.
