Wireless tower and data center REIT, 49% U.S. Read October 20, 2026 from the annual report for the period ending December 31, 2025, filed February 24, 2026. Ranked 7 of the 17 Real Estate companies read so far, by the share within reach now.

The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.

What follows from the reading

Share of working time within reach of AI, on the long-run pace at four in five: 25% now, 40% at the end of 2027, 45% at the end of 2028, 46% at the end of 2030. By the patterns, the work is about 46% desk work, 24% people work and 29% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 54% of the working time stays with people (conversation, in-person and hands-on work), 35% becomes checking a model's work and 9% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
