Will GameStop acquire eBay?

Platform comparison

Market context

GameStop has just escalated its bid for eBay with a fresh $55.5 billion cash-and-stock offer, directly challenging eBay’s board after their initial rejection of a similar proposal. This renewed aggression, announced within the last 48 hours, shifts the narrative from a stalled negotiation to an active, high-stakes corporate raid, explaining the current 13% crowd-implied probability despite eBay’s firm dismissal of the deal as “neither credible nor appealing”[1][5].

Historically, such disproportionate takeover attempts by meme-stock entities against established e-commerce giants rarely succeed without a shareholder revolt or a strategic pivot by the target. Comparable cases, like the failed attempts by smaller retailers to acquire Amazon competitors, show that financing uncertainty and valuation gaps are the primary barriers; here, GameStop’s market cap of roughly $10 billion versus eBay’s four-times-larger size creates a credibility deficit that analysts have consistently highlighted[3][4].

Traders must now monitor whether CEO Ryan Cohen will bypass eBay’s board and launch a tender offer directly to shareholders, a tactic he hinted at after the initial rejection[4]. Key catalysts include any announcement of a special shareholder meeting, updates on the $20 billion debt financing commitment from TD Securities, or public pressure campaigns that could force eBay’s directors to reconsider[1][2]. The next significant move is likely to be a formal tender offer or a shareholder meeting application, as Cohen has reiterated his determination to acquire eBay despite the board’s stance[3].
