Will GameStop acquire eBay?

Platform comparison

Market context

The real-world event driving this market is GameStop’s surprise non-binding proposal to acquire eBay for approximately $55.5 billion, a deal structured as a 50% cash and 50% stock offer at $125 per share. In prediction markets, a YES share pays out if the official announcement of an acquisition or merger occurs before the settlement deadline, while a NO share pays out if it does not; here, the crowd currently assigns only a 13% probability to the deal being announced by December 2026.

Historically, hostile or unsolicited bids of this magnitude rarely succeed without board cooperation, especially when the target’s leadership has not yet endorsed the offer. eBay’s board has stated it will carefully review the proposal, and past cases like eBay’s 2005 acquisition of Skype for $2.6 billion show that even large tech firms can be acquired, but only after lengthy negotiations and shareholder approval. The current low probability reflects the uncertainty of whether eBay’s directors will accept GameStop’s terms or reject the bid outright.

Traders should monitor eBay’s board’s formal response, any shareholder meetings, and updates on GameStop’s financing from TD Securities, which has committed up to $20 billion in debt. A recent report from the BBC confirms the offer details and notes that eBay’s board has not yet decided on a course of action, making their next statement the most immediate catalyst. If eBay’s board rejects the bid or if financing falls through, the YES probability will likely drop further; conversely, any sign of board interest could sharply increase it.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
