The $40bn takeover of Aligned Data Centers by MGX, AI Infrastructure Partnership (AIP) and BlackRock's GIP has officially closed, marking the largest-ever transaction in the data centre sector. UK buyers weighing colocation, cloud, or on-prem AI builds should read the deal as a signal of where global capital — and GPU allocation power — is now concentrating.

What actually closed this week
Macquarie Asset Management has sold 100 percent of Aligned Data Centers to a consortium made up of AIP, BlackRock's Global Infrastructure Partners (GIP), and Abu Dhabi's MGX, in a deal worth $40bn — with a further $5bn committed specifically for Aligned's expansion pipeline. Aligned, founded in 2013 and headquartered in Dallas, Texas, operates 51 campuses across North and South America with more than 6.4GW of operational and planned capacity. CEO Andrew Schaap and the existing management team stay in place, and the Dallas HQ remains unchanged.
Macquarie's Anton Moldan framed the sale as positioning Aligned to keep meeting "surging demand for AI and cloud capacity" — language that underlines why hyperscale-adjacent capital is chasing platforms like this rather than building from scratch.
Why this is the biggest deal the sector has seen
The $40bn price tag dwarfs the previous record — Blackstone's $16.6bn purchase of AirTrunk in 2024 — and lands in a market that was already running hot. Data centre M&A topped $69bn across 113 deals in 2025 alone, according to S&P Global Market Intelligence figures cited by DCD. Aligned's deal alone represents more than half that entire annual total, in a single transaction.
That scale matters for UK buyers because it confirms AI-ready capacity is now being priced and acquired at infrastructure-fund scale, not conventional real-estate scale. AIP itself was reported to have raised over $12.5bn towards an eventual $30bn equity target, with debt financing potentially pushing total firepower into the tens of billions more — capital depth that smaller UK and European operators simply cannot match when competing for land, power connections, or GPU supply contracts.
What it means for UK AI infrastructure pricing
Aligned's footprint sits entirely across North and South America — the deal doesn't add or remove UK capacity directly. But the pricing implication for UK buyers is indirect and real: when consortiums this large lock up multi-gigawatt platforms, they gain outsized leverage over GPU allocation, chip supply agreements, and power procurement globally, which can tighten availability and firm up pricing everywhere capacity is scarce, the UK included.
Buyers negotiating 2026–2027 contracts should assume less room to haggle on wholesale colocation and GPU-cloud rates than in previous cycles. It's worth using tools to calculate your AI GPU requirements before committing to long-dated agreements, and to track AI server pricing trends as consolidation ripples through the supply chain.
Capacity and availability: the UK constraint doesn't disappear
Because Aligned's assets are entirely in the Americas, UK-specific vacancy and build-out timelines aren't addressed by this deal directly — the binding constraint for UK buyers remains grid connection queues and power availability, not this transaction. Still, the broader consolidation trend it exemplifies means the largest, best-connected sites globally are increasingly held by a small number of capital-rich consortiums, which can crowd out mid-tier developers competing for the same construction crews, transformers, and cooling equipment supply chains that UK sites also depend on.
Buyers should factor this into site selection now. Reviewing guidance on choosing a UK colocation data centre and understanding UK data centre power costs is more important in 2026 than in prior years, given how tight global equipment and power markets have become.
Vendor lock-in risk from a concentrated ownership map
The consortium behind AIP brings together an unusually dense set of technology and capital names — reported to include Microsoft, Nvidia, xAI, MGX, BlackRock/GIP, the Kuwait Investment Authority and Temasek. That concentration matters for procurement strategy: when the same capital pool sits behind the infrastructure, the chips, and in some cases the AI model providers, UK enterprises risk finding fewer genuinely independent options across the stack.
This is a moment to stress-test vendor diversification rather than assume it. Businesses should optimise their IT procurement strategy to avoid single-consortium dependency, and revisit cloud vs. on-premise TCO assumptions given how ownership concentration could shape future pricing power.
Practical steps for UK buyers in 2026
None of Aligned's capacity is in the UK, so there's no direct capacity unlock for British buyers from this deal — the effect is entirely upstream, through capital concentration and global demand pressure. Firms locking in 2026–2027 capacity commitments should benchmark GPU-cloud pricing now, since it's cheaper to compare UK GPU cloud rental prices before larger consortiums reprice the market than after.
For those weighing capital versus lease structures on new hardware, it's also worth reviewing options to explore IT infrastructure financing given how much capital is now flowing into infrastructure ownership rather than pure hardware sales — a dynamic that could shift how vendors structure UK server and colocation deals over the next 12–18 months.
