GameStop is reportedly preparing an offer to acquire eBay as part of a plan to build a $100-billion plus company, with a potential offer arriving as early as this month. While GameStop is currently valued at $11 billion compared to eBay's $46 billion valuation, reports indicate GameStop has already been building a stake in eBay shares. The acquisition may involve strategic financing or a direct offer to eBay shareholders if the company is not receptive to the initial proposal.
