eBay’s May 2026 rejection of GameStop’s $55.5 billion unsolicited cash-and-stock bid, citing financing and credibility concerns, remains the dominant factor anchoring the 94.5% market-implied probability of “No.” GameStop has increased its eBay stake to nearly 10% and signaled proxy-fight intentions, yet months of stalled talks, skepticism over the $20 billion TD Securities commitment letter, and the vast size disparity—GameStop’s roughly $13 billion market cap versus eBay’s larger valuation—have reinforced trader consensus. Near-term catalysts such as the October 30 warrant expiration and any renewed shareholder pressure could test the odds, but sustained eBay board opposition and execution hurdles continue to support the strong “No” positioning.
