Three operators announce $5.98B in transactions today while Dublin, London, and Amsterdam all score above 70 on the DCPI Constraint index
## Capital Acceleration
Three major data-center operators deployed $5.98 billion in capital today, with Hut 8 announcing a $4.25B, 352 MW expansion, Google committing $920M across two separate transactions (including an acquisition from xAI), and Stack acquiring assets from Amazon for $810M. The single-day capital deployment underscores the velocity of infrastructure investment as AI workloads scale — and the urgency to lock capacity before power constraints bind further.
## Constraint Reality
While capital flows freely, buildable land is shrinking. Dublin, OH scored 72.5 on today's DCPI Constraint index (PJM), with only 22.4 points of Excess Power headroom. London (NGESO) and Amsterdam (ENTSOE-NL) both broke 70 on the Constraint scale — 71.8 and 70.0 respectively — with Excess Power scores in the low teens. For context, anything above 65 signals meaningful interconnection delays, environmental review friction, or grid capacity limits.
Meanwhile, Cheyenne, WY (WECC) holds 69.5 Excess and just 22.5 Constraint — the inverse profile. Rural SPP markets in Kansas score 67.2 Excess. The gap between where capital *wants* to go (metro fiber + colo ecosystems) and where power *actually is* (rural WECC, SPP) has never been wider.
## What It Means
CyrusOne's 380 MW power purchase from Calpine (no disclosed price) is the tell: operators are buying generation assets directly rather than waiting in interconnection queues. The M&A and PPA announcement pace suggests 2026 will close as the highest-volume infrastructure year on record — and that the winners will be those who locked power early, not those who optimized for latency or legacy fiber.
