Ultimately, the filing highlights a tension between eBay's ability to generate cash and the increasing cost of maintaining its global marketplace. The success of the investment thesis now depends on whether AI-driven efficiencies can offset the rising cost of revenue and the potential for multi-billion dollar regulatory penalties in international markets.
