Together the three companies GameStop, Ebay, and PSA form a natural ecosystem flywheel:

PSA authenticates/grades ➡️ GameStop drives new supply (Power Packs + retail) and accessibility ➡️ eBay provides the big secondary marketplace for resale. Volume in one boosts the others, with zero head-to-head competition. Recent results show this is working well for all three.

Just Speculation: Think Japanese keiretsu or tech partnerships where companies take stakes to lock in long-term cooperation. It signals commitment without a full merger. PowerPacks are new and generating hype/buzz, and the partnerships are already delivering results. A cross-holding could accelerate that flywheel. Rumors are swirling about GameStop eyeing a bigger play on eBay. A mutual investment could be a lower-drama stepping stone.
