EBAY vs CCI Comparison

Founded in 1995, eBay operates one of the world's largest online marketplaces, connecting buyers and sellers across more than 190 markets. In 2025, the firm generated $11.1 billion in revenue on nearly $80 billion of gross merchandise volume, serving 135 million active buyers and 18 million active sellers (users who closed at least one transaction in the past year). The firm monetizes its marketplace primarily through transaction fees and advertising, with 52% of revenue derived from the US and the remainder from international markets. In a bid to expand its reach among Generation Z and in the recommerce sector, eBay announced the $1.2 billion acquisition of fashion resale app Depop from Etsy in early 2026.

Crown Castle owns or manages roughly 40,000 wireless towers in the United States. It leases space on its towers to wireless service providers, which install equipment to support their wireless networks. The company has a very concentrated customer base, with about 90% of its revenue from the Big Three US mobile carriers: Verizon, T-Mobile, and AT&T. Crown Castle has plans to divest its fiber business, which is expected to be finalized in the first half of 2026. After that, it will be a stand-alone tower operator. Crown Castle operates as a real estate investment trust.
