GameStop, led by CEO Ryan Cohen, launched an unsolicited $56 billion bid for eBay that was rejected; Cohen is now reported to be exploring a commercial partnership that could include board seats. The developments stem from a Bloomberg report citing unnamed sources, with GameStop holding a 9.8 percent stake in eBay. eBay's market capitalization remains nearly five times larger than GameStop's, which operates roughly 1,600 U.S. retail locations.
