Three deals totaling 21.7 GW capacity closed June 9 as AI infrastructure consolidation accelerates; Cheyenne leads build markets at 69.5 excess power score
## Hyperscale Portfolio Sprint
Stack Infrastructure completed acquisition of a **20,000 MW data center portfolio** from Blackstone on June 9, 2026 — the largest single-day capacity transaction tracked by DC Hub since platform launch. The deal anchors a 48-hour M&A window that logged $5.5 billion in combined value across six transactions, including:
- **Meta**: 1,400 MW capacity acquisition (buyer, no seller disclosed)
- **Hut 8**: $4.25B portfolio for 352 MW (June 8)
- **Google / xAI**: $920M transaction (June 8)
- **Ares Management**: $295M capital deployment (June 9)
The Stack-Blackstone transfer alone exceeds the **combined MW capacity** of all facilities currently online in Northern Virginia's Ashburn market, DC Hub's most-tracked US colocation hub.
## Build vs. Buy Geography
While M&A targets existing assets, DC Hub's **DCPI Excess Power Index** shows where new construction pencils:
- **Cheyenne, WY** (WECC): 69.5 excess, 22.5 constraint — top US build market
- **Rural SPP, KS**: 67.2 excess, 22.5 constraint
- **Dublin, OH** (PJM): 22.4 excess, 72.5 constraint — avoid list
London (UK, NGESO) and Amsterdam (NL, ENTSOE-NL) remain Europe's tightest markets at 13.5 and 13.7 excess scores respectively, with constraint indices above 70.
## What It Means
The 20 GW Stack portfolio is **14× larger** than a typical hyperscale campus. At current AI training densities (50-100 MW per cluster), the transaction represents capacity for 200-400 frontier model training runs — or enough inference infrastructure to serve 2 billion daily API calls. Blackstone's exit and Meta's parallel 1.4 GW buy signal a capital rotation: financial sponsors harvesting, hyperscalers integrating.
