Will GameStop acquire eBay?

Platform comparison

Market context

GameStop CEO Ryan Cohen has formally proposed a non-binding $55.5 billion takeover of eBay, offering $125 per share in a 50/50 cash-and-stock mix, yet eBay’s board has dismissed the bid as neither credible nor appealing. Despite this rejection, the prediction market currently implies a 13% chance of an official acquisition announcement before the end of 2026, a figure that diverges sharply from analyst consensus, which largely views the financing and strategic rationale as unworkable. While sportsbook lines on similar corporate events often hover near 5–10% for hostile takeovers of established tech firms, this contract’s implied probability sits slightly elevated, suggesting traders are pricing in Cohen’s willingness to escalate directly to shareholders.

Historical precedents for hostile takeovers in the e-commerce sector, such as eBay’s own acquisition of Skype in 2004, typically require board cooperation or a successful tender offer backed by overwhelming shareholder support; Cohen currently holds only 0.006% of eBay’s voting shares outright, with most exposure derived from derivatives that confer no voting rights unless physically executed. Comparable cases like Microsoft’s 2016 acquisition of LinkedIn succeeded through negotiation, whereas hostile bids like Amazon’s 2017 attempt to acquire Whole Foods failed until a revised, board-friendly offer was presented. The 13% market probability thus reflects a narrow path where Cohen bypasses the board entirely, a scenario that remains statistically rare given eBay’s defensive posture and the contingent nature of GameStop’s $20 billion debt financing from TD Securities.

Traders should monitor three key catalysts: any public tender offer initiated by Cohen, announcements of a special shareholder meeting to elect new directors, and updates on the investment-grade credit rating required to unlock TD Securities’ financing commitment. Reuters reported on 27 May 2026 that Cohen may convene a special meeting or apply public pressure to wear down eBay’s board, while CNBC noted on 25 June 2026 that Cohen has sacrificed personal pay to fund the effort, though details on his next move remain vague. An official announcement of a partial sale or merger agreement would resolve the market to “Yes,” regardless of whether the transaction completes before the settlement window ends on 31 December 2026.
