GameStop doesn't have (even close to) $55.5B. Their offer from the letter is literally impossible:
> Our offer is $125.00 per share, comprising 50% cash and 50% GameStop common stock
Even if you magically included all existing GameStop stock in the offer, it still would not comprise 50% of $55.5B.
EDIT: looks like it's not impossible and I misunderstood. It's a proposed change of leadership with a $25B injection of cash to sweeten the deal. GameStop would issue shares which would capture the original eBay value (since GameStop would own eBay after the trade), making that part a wash. At least assuming people owning eBay stock currently would value the combined company at at least the sum of their parts, which is a big if.
