How Market Researchers Use Telecom Tower REITs Data

A researcher covering this vertical runs three loops: sizing the installed base, ranking the owners, and tracking the listed vehicles. Sizing means a defensible national tower count for a deck footnote; ranking means an ownership league table showing how concentrated the market is; tracking means following American Tower (AMT), Crown Castle (CCI) and SBA Communications (SBAC) as the listed proxies for private-market infrastructure values. Unlike a quant, you need quotable figures with named sources and stated as-of dates more than you need tick-level feeds. Datadory catalogs 13 primary Telecom Tower REITs datasets plus 9 related records from adjacent industries, and 9 of the 13 primaries are free. They split into three layers: regulatory infrastructure records (FCC), industry aggregates (WIA, Wireless Estimator) and equity feeds (Nasdaq, Polygon.io, Yahoo Finance). The persona page market researchers collects these sources ranked for research workflows; this page walks through how each one feeds a specific deliverable.

Two independent counts anchor the sizing chapter, and citing both is stronger than citing either. The Wireless Infrastructure Association's annual 'Wireless Infrastructure By the Numbers' report, published through its Resource Library, counts 158,500 purpose-built US towers and 254,850 macrocell sites at end-2025; the series covers four consecutive year-end editions, so a multi-year trend line is available. The full PDF sits behind a HubSpot lead-capture form at go.wia.org, but headline statistics are freely readable in library posts and press releases. Wireless Estimator independently compiles a ranked list of 276 US tower-owning companies totaling about 149,196 towers, each company's count individually timestamped with a dataset-level verification stamp of 7/1/2026. That list explicitly excludes foreign-owned portfolios, which explains part of the gap against WIA's figure - a methodological distinction worth stating in your methodology note rather than papering over. For context across the wider catalog: of the 1,744 datasets Datadory catalogs, 82.4% are free to access, and government and public sources make up 781 records (44.8%) - this industry leans on that public-data backbone heavily.

Start with the telecom-tower-reits data guide for the full 22-dataset landscape and a stack-building walkthrough, then go deeper on this page's two signature workflows: the sizing chapter rests on Wireless Infrastructure Association Resource Library and Wireless Estimator — Tower Industry News and Database. The ranked source list lives on our market researchers page, the best telecom-tower-reits datasets shortlist ranks every record, the free telecom-tower-reits datasets list covers the no-budget route, and the telecom-tower-reits data hub indexes each dataset, API and source profile in the vertical.
