Market context
GameStop has formally submitted a non-binding proposal to acquire eBay for approximately $55.5 billion, a cash-and-stock deal valued at $125 per share, which eBay’s board has publicly rejected as “neither credible nor appealing” [5][7]. The market currently implies a 13% chance of a successful announcement by the end of 2026, reflecting the significant hurdle of overcoming eBay’s board resistance despite GameStop’s 5% stake in the target [2][4].
Historically, hostile bids or unsolicited offers from retailers to e-commerce giants rarely succeed without board cooperation, as seen when eBay’s own acquisition of Skype faced intense scrutiny and eventual divestiture, underscoring the difficulty of merging disparate business models [6]. Comparable cases, such as Amazon’s acquisition of Whole Foods, succeeded only after lengthy negotiations and board approval, whereas hostile attempts like Microsoft’s bid for Yahoo ultimately failed, framing the current low probability as a rational assessment of the board’s firm stance [7].
Traders should monitor for any shift in eBay’s board position, new financing confirmations beyond TD Securities’ $20 billion letter, or unexpected shareholder activism that could force a board reconsideration [4][5]. A catalyst would be an official announcement from either company, regardless of deal completion timing, so conditional orders programmed to trigger on press releases from GameStop’s investor relations or eBay’s corporate communications remain the most direct execution strategy [5]. Recent reporting confirms eBay’s rejection, making a reversal the primary variable to watch for a “Yes” resolution [7].
Methodology
We track Will GameStop acquire eBay? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
