SoftBank agrees $4bn DigitalBridge acquisition; close 2H 2026 Hut 8’s $10bn Louisiana data centre: Jacobs EPCM; Vertiv; up to 85% financing underwritten US federal push to centralize data-centre grid connection authority raises legal risk Interconnection studies targeted to be 5x faster via Open Power AI Consortium Power scarcity signals: utilities restarting older plants amid AI load growth; PPAs/transmission take years

Market overview (Global) — 30 Dec 2025 (UTC)

Strategic and capital-market activity continues to accelerate around AI-driven digital infrastructure, with a major prospective platform acquisition and multiple signals of tightening power/grid constraints. On the supply side, developers are pushing large, high-density builds (100+ kW racks) and pursuing project finance structures; on the demand-enablement side, policy and utility processes (interconnection studies, permitting, and grid connection authority) are emerging as key swing factors for delivery timelines.

Risks and watchpoints (near-term)

  • Regulatory/legal uncertainty on grid connections (US): A reported federal push to fast‑track rules that would give Washington new authority over large data-centre grid interconnections could trigger legal challenges from states and regulators, potentially delaying rulemaking and creating near-term execution risk for projects dependent on interconnection outcomes (Federal push for control of data‑center grid connections sparks backlash).
  • Power availability and emissions backlash: Utilities restarting older, inefficient plants to meet AI-driven load growth raises cost, emissions, and reputational risk; it also signals that “bridging” thermal capacity may persist while PPAs, on‑site generation, and transmission take years (AI data center boom forces revival of old power plants).
  • Financing/execution concentration risk in mega-projects: Large builds relying on high leverage and complex delivery stacks (EPCM + OEM partners) face schedule/cost overrun risk, counterparty risk, and refinancing risk (notably where underwriting is up to a high share of project-level capital) (Woodside signs LNG deal with Turkey; Hut 8 names construction partner).
  • M&A close timing and approvals: SoftBank’s planned acquisition of DigitalBridge is not expected to close until 2H 2026 and is subject to regulatory approvals—creating uncertainty for portfolio strategy and potential interim asset rotation at DigitalBridge (SoftBank to acquire DigitalBridge for approximately $4.0 billion).
  • Upside catalyst—faster interconnection studies: The Open Power AI Consortium’s target of 5x faster interconnection studies could shorten queues and improve project IRRs if adopted at scale (Plano’s KYRO AI joins Open Power AI energy consortium).

Power, fuel, grid & interconnection highlights

LNG and “bridge” thermal capacity signals

  • Woodside Energy signed a binding agreement to supply Turkey’s BOTAS with ~5.8 bcm of LNG over up to nine years starting in 2030, mainly sourced from Woodside’s Louisiana LNG project (deliveries expected to begin 2029)—underscoring the longer-dated fuel infrastructure build that may be relevant to power adequacy planning in gas-linked markets (Woodside signs LNG deal with Turkey; Hut 8 names construction partner).
  • Separately, utilities are reported to be restarting decade-old, inefficient power plants to meet hyperscale/AI data centre demand growth, while operators pursue long-term PPAs, on-site generation, and dedicated transmission that take years to deliver (AI data center boom forces revival of old power plants).

Interconnection process as an investable bottleneck

Policy and regulation

  • The Trump administration reportedly directed federal regulators to fast‑track rules granting Washington new authority over how large data centers connect to the grid; Energy Secretary Chris Wright said the move would speed connections and allow operators to build their own power, while state regulators and officials warn of potential violations of the Federal Power Act and expect legal challenges (Federal push for control of data‑center grid connections sparks backlash).

Networks & enabling infrastructure (fiber)

Technology & operations notes (select)

  • Liquid cooling reliability/efficiency: a proof‑of‑concept IoT monitoring system combining LSTM forecasting and Random Forest detection targets coolant leaks in liquid‑cooled GPU-centric AI data centers; it reports 96.5% detection and 87% forecasting accuracy, with leak forecasts 2–4 hours ahead and sudden event detection within 1 minute (ASHRAE-aligned synthetic data). The authors estimate ~1,500 kWh/year energy waste avoidance for a 47‑rack facility (Smart IoT Leak Forecasting for Energy-Efficient Liquid-Cooled AI Data Centers).
  • Siting/embedded generation optimization (distribution networks): a mixed-integer nonlinear optimization plus genetic algorithm framework in an IEEE 33‑bus case study selected bus 14 with 1.10 MW DG, reducing losses (reported 202.67 kW → 129.37 kW) at an investment cost of $1.33m (Optimal Data Center Placement for Distribution Networks Using Intelligent Algorithms).
