CoreWeave, a rapidly scaling artificial intelligence infrastructure company, announced on October 15, 2025, a significant expansion of its Washington, D.C. office. The company has leased an additional 22,590 square feet at 1001 Pennsylvania Avenue NW, increasing its total presence in the building by 79 percent. This expansion occurs within a soft D.C. office market that has a 20.4 percent vacancy rate, highlighting a trend where 68 percent of tenants signing leases over 10,000 square feet in the third quarter of 2025 grew their footprint. The move solidifies CoreWeave's presence in a strategic location, six blocks from the White House and adjacent to the FBI headquarters, as it continues to scale its business and operations.
