Will GameStop acquire eBay?

Platform comparison

Market context

GameStop has launched an unsolicited, non-binding proposal to acquire eBay for approximately $55.5 billion, offering $125 per share in a 50% cash and 50% stock mix, yet eBay’s board has advised shareholders to take no immediate action while reviewing the bid[1][4]. With the market currently pricing a 13% chance of a formal announcement by December 2026, the consensus leans heavily toward rejection, viewing the offer as a speculative gambit by Ryan Cohen rather than a credible transaction[2][6]. However, value may sit contrarian for those betting on the 13% spot, as Cohen has already secured a 5% stake in eBay and $20 billion in debt financing from TD Bank, positioning him to bypass the board and appeal directly to shareholders if the initial offer is rebuffed[2][3].

Historically, unsolicited bids from retail disruptors often fail unless backed by overwhelming shareholder pressure or regulatory shifts, yet Cohen’s strategy mirrors hostile takeover tactics that have occasionally succeeded when the acquirer holds significant equity and financing ready[2][6]. The critical catalysts for traders include eBay’s board’s definitive response, any shareholder vote Cohen might force, and regulatory approvals, all of which remain uncertain as the deal is non-binding and subject to financing hurdles[5][6]. Recent reporting confirms Cohen’s intent to escalate to shareholders if eBay rejects the offer, making the next board statement or shareholder filing the primary event to watch for a potential shift in probability[1][2]. Investors should monitor GME stock volatility, which has already risen 6.33% on deal speculation, as a proxy for market sentiment on the deal’s viability[6].
