The record, newest first

  1. DCD tied the purchase to 1001 Third Ave. S., bought from Legacy Investing, and reported a $7 million investment by RealVantage. (DatacenterDynamics, March 25, 2026)

  2. Cloud Capital and its partner Arcapita announced they had bought a 21 MW Minneapolis data center with plans to expand it to 31 MW. (Cloud Capital, Jan. 13, 2026; Cloud Capital, Oct. 23, 2026)

Conflicts and open questions

  • Cloud Capital's release does not give the address; the link to 1001 Third Ave. S. comes from DCD.
  • Floor area: 47,000 sq ft in 2021 (DCD); Cloud Capital's investments page lists 327,844 sq ft for its Minneapolis site, likely the whole building. Left blank.
  • Cloud Capital's investments page says the Minneapolis site was acquired in 2025; the release is dated Jan. 13, 2026.

The full record

Status note
Cloud Capital and Arcapita bought the site from Legacy Investing; most current capacity is leased long term to an unnamed AI and cloud provider. RealVantage later put in $7 million.
Power note
Cloud Capital states 21 MW now, with a 10 MW expansion planned to 31 MW. In 2021 DCD reported 3.9 MW, expandable to 10.4 MW; the gap reflects growth since then, not a dispute between current sources.
