Will GameStop acquire eBay?

Platform comparison

Market context

GameStop has formally submitted a non-binding $55.5 billion takeover bid for eBay, valuing the e-commerce giant at $125 per share in a 50/50 cash-and-stock mix, yet the market still prices a successful acquisition at only 13% YES. This low probability reflects the consensus view that the proposal is a hostile, leveraged buyout attempt by a video-game retailer with limited e-commerce experience, rather than a strategic merger. In comparable cases, such as eBay’s acquisition of Skype or Microsoft’s failed bid for Yahoo, non-binding offers from industry outsiders often stall during board reviews unless backed by overwhelming shareholder pressure or regulatory clearance. Here, eBay’s board has already advised shareholders to take no immediate action while reviewing the proposal, suggesting the path to a "Yes" resolution requires a significant shift in corporate governance or a surprise shareholder revolt.

The critical catalysts for traders are the board’s formal response timeline, GameStop’s ability to secure the remaining $35.5 billion in financing beyond its TD Bank commitment, and any potential hostile tender offer to eBay’s shareholders. Recent reporting from IGN confirms GameStop holds a 5% stake in eBay and has a $20 billion debt commitment, but the gap between this and the total bid remains a major dependency. Contrarian value may sit slightly above the 13% mark if GameStop escalates to a direct shareholder appeal, as Ryan Cohen has indicated he will do if eBay rejects the offer. However, the settlement window ending in 2026 allows ample time for regulatory hurdles or financing failures to derail the deal, making the current price a fair reflection of the high execution risk facing this underdog acquisition attempt.
