Prediction markets put the probability at 12%: Will GameStop acquire eBay. Currently, markets see this as unlikely (12% YES).
GameStop’s pursuit of eBay has entered a more aggressive phase, with the company’s stake in the online marketplace nearly doubling to **43.4 million shares**, or approximately **9.8%** of eBay, according to a **July 20, 2026** SEC filing. This escalation follows GameStop’s initial **$56 billion** takeover proposal in May, which eBay’s board publicly rejected as “neither credible nor attractive” after a thorough review. CEO Ryan Cohen has signaled he will not relent, telling Bloomberg that eBay has not reached out since the rejection, while separately withdrawing his own **$35 billion** compensation package to focus entirely on the acquisition effort. The proposal would fundamentally restructure eBay’s balance sheet, shifting it from minimal leverage to over **5x EBITDA** with **$25 billion** in new debt, a risk profile that analysts note eBay shareholders could replicate themselves without accepting Cohen’s leadership.

The strategic rationale behind the potential GameStop acquire eBay scenario hinges on Cohen’s view that the two businesses are “highly complementary,” a position he reiterated in a public interview with Piers Morgan in late June. GameStop has moved to bolster its firepower for the deal, filing with the SEC for approval to increase its Class A shares from **1 billion to 2.5 billion**, a move explicitly designed to support acquisitions, fundraising, and corporate changes. The company has also dropped its CEO pay package, a decision announced on **June 24, 2026**, to streamline focus on the takeover. Despite these maneuvers, eBay has maintained its stance that the offer undervalues its business and carries excessive financial risk, with the marketplace’s board deeming the leveraged structure unattractive for its shareholders.

Looking ahead, the central question is whether Cohen can force a deal without eBay’s cooperation, given his escalating ownership stake and public pressure campaign. GameStop’s increased holdings to nearly **10%** make it one of eBay’s largest active shareholders, giving Cohen a platform to push for board changes or a shareholder vote on the acquisition. However, eBay’s rejection and the structural concerns around the **$25 billion** debt load suggest the path to a friendly merger remains blocked. The market’s current assessment, reflected in a **12% YES / 88% NO** probability for a GameStop acquire eBay outcome, indicates skepticism about the deal’s completion, though Cohen’s history of aggressive activist tactics leaves room for further escalation, including potential proxy fights or hostile tender offers in the coming months.
