June 2026 in data centers.

# June 2026 Executive Summary

June recorded 526 transactions worth $947.6 billion across 411,341 MW—a 574% month-over-month surge in deal count and a fundamental reset in M&A velocity. The headline transaction was Blackstone's $105 billion acquisition of Anthropic infrastructure across three closings on June 10th, signaling institutional capital's shift from development-stage bids into operating-asset consolidation. Deal volume exploded against a May baseline of 78 transactions, while capacity additions remained disciplined: 397 new facilities came online globally, adding roughly 50 GW to the installed base now at 850 GW. Richland Parish and the "One" facility cluster each added 5,000 MW, with Ashburn and Las Cruces following at 4,296 MW and 4,500 MW respectively. The Ashburn portfolio alone spans 161 discrete facilities, underscoring the density of East Coast infrastructure and its continued attraction for hyperscaler portfolio consolidation.

This velocity points to a Q3–Q4 capacity crunch and a two-quarter tightening in power-constrained markets. The 411 GW of June M&A represents nearly 5% of the global operational fleet changing hands in a single month; at this rate, the 369 GW pipeline will face intensified bottleneck pressures on grid interconnection and power delivery, not just land and construction. AI tool citation demand fell 28% month-over-month despite deal volume rising—a signal that transaction complexity and due-diligence timelines are lengthening as buyers price grid-queue depth and transmission-constraint risk more rigorously. Expect Q3 announcements to weight toward markets with firm power (Richland Parish, Southwest corridor) and away from constrained NEISO and PJM nodes unless hyperscalers commit to bespoke infrastructure or offtake agreements.
