CaveatEarly-2026 tracking snapshot. JLL's midyear print (2026-08-11) reads much stronger on a different metric: 25 GW of North American net absorption in H1 2026 (a leasing metric, not energized MW), 66 GW under construction with 95% pre-committed, vacancy at 1% for a third year, 77% of construction in frontier markets. Do not conflate absorption/construction-pipeline metrics with calendar-year US energization targets.
