Top 10: Investors Funding Data Centre Expansion​

Growing AI workloads, sovereign cloud demands and latency‑sensitive edge services are reshaping how capital is deployed into digital infrastructure. 

The firms in this week's Top 10 have moved beyond opportunistic deals to build specialist teams, multibillion‑dollar funds and repeat platforms focused on data centres, GPUs and critical power. Their portfolios span hyperscale campuses, sustainable colocation and high‑performance computing sites that underpin today’s cloud and tomorrow’s AI‑native applications. 

For data centre operators, vendors and hyperscalers, these investors are leading the field: backing management teams, funding M&A roll‑ups and underwriting gigawatt‑scale development pipelines in key regions. 

Collectively, they illustrate how infrastructure, private equity and hedge funds are converging around data centres as a core, long‑duration asset class.​

10. Magnetar Capital​

• Headquarters: Evanston, Illinois, United States​
• CEO: Alec Litowitz (Founder; Managing Partner and CEO)​
• Year founded: 2005

Magnetar Capital has emerged as a quiet but powerful backer of AI‑focused digital infrastructure through its stake in GPU cloud specialist CoreWeave. By leading multiple funding rounds and convertible structures, Magnetar helped transform CoreWeave from a niche cloud player into a multi‑campus platform rapidly expanding its data centre footprint in North America and Europe. For data centre stakeholders, Magnetar’s playbook shows how sophisticated credit and growth equity structures can unlock accelerated build‑outs for GPU‑dense facilities serving hyperscale AI workloads.​

9. The Carlyle Group​

• Headquarters: Washington, D.C., United States​
• CEO: Harvey Schwartz​
• Year founded: 1987

Carlyle has positioned digital infrastructure as a core theme across its global private equity and infrastructure platforms. Its backing of ark data centres (formerly Involta) underlines a strategy of scaling regional colocation and hybrid cloud platforms that can follow enterprise and public sector demand into second‑tier markets. For operators, Carlyle’s approach blends brownfield expansion with M&A, using its capital and relationships to grow footprint, interconnection density and managed services around high‑value customers. This makes Carlyle a key partner for mid‑market platforms looking to professionalise and expand.​

• CEO: Marc Ganzi​
• Year founded: 2013 as Digital Bridge (heritage platform dates to 1991 under predecessor entities)

DigitalBridge is one of the pure‑play specialists in digital infrastructure, spanning towers, fibre, edge and large‑scale data centres. Its acquisition of DataBank created a platform for aggressive regional data centre growth and industry consolidation across the US. With a bench of executives boasting decades of data centre experience, DigitalBridge focuses on scaling platforms via both organic development and bolt‑on acquisitions. For the Data Centre Magazine audience, DigitalBridge exemplifies the trend toward sector‑dedicated capital that understands power density, connectivity and SLAs as well as it understands IRR.​

• CEO: Dominique Senequier​
• Year founded: 1996 (as AXA Private Equity; rebranded Ardian in 2013)​

Ardian has built a sizeable infrastructure franchise with a strong focus on digital and energy‑transition‑aligned assets. Its acquisition of Verne (formerly Verne Global) and commitment of up to US$1.2bn to expand its Nordic data centre platform highlight a strategy centred on renewables‑rich, cool‑climate locations ideal for AI workloads. For data centre leaders, Ardian’s plan to almost quadruple Verne’s sold capacity demonstrates how long‑term infrastructure capital is enabling sustainable, grid‑integrated campuses in power‑constrained Europe. This approach directly addresses hyperscaler and enterprise ESG requirements.​

• CEO: (Managing partners lead the firm; founded by Mitt Romney, T. Coleman Andrews III and Eric Kriss)​
• Year founded: 1984

Bain Capital has leveraged its private equity and infrastructure expertise to back large‑scale data centre platforms, particularly across Asia. The merger of ChinData with Bridge Data Centres created a powerhouse focused on hyperscale IT infrastructure across China, India and Southeast Asia, targeting more than 300MW of capacity. That strategy aligns with hyperscalers’ need for trusted local partners capable of delivering build‑to‑suit campuses, renewable integration and lifecycle operations at scale. For industry players, Bain’s activity underlines Asia’s role as a growth frontier for third‑party data centre platforms.​

5. Stonepeak Infrastructure Partners​

• Headquarters: New York, United States​

EQT Infrastructure has emerged as a key owner of global data centre platforms, with a strong sustainability and “future‑proofing” thesis. Its acquisition of EdgeConneX provided firepower to accelerate expansion from edge locations into larger hyperscale deployments worldwide. EQT brings a hands‑on ownership model, supporting management teams on energy efficiency, renewable procurement and digital transformation, while deploying significant capex for new builds. For data centre operators, EQT illustrates how infrastructure investors can partner for long‑term growth rather than short‑cycle financial engineering.​

1. Blackstone​

• Headquarters: New York, United States​
• CEO: Stephen A. Schwarzman (Chairman and CEO)​
• Year founded: 1985

Blackstone sits at the top of this list due to the sheer scale and ambition of its data centre bets, led by its 2021 acquisition of QTS in a US$10bn take‑private. Under Blackstone’s ownership, QTS has grown from around 400 MW to roughly 3GW of capacity, with its development pipeline surging from US$1 to about US$25bn as AI and cloud demand exploded. Alongside this, Blackstone has helped finance CoreWeave’s rapid expansion, with multi‑billion‑dollar debt facilities enabling the GPU cloud specialist to build out dozens of highly specialised AI data centres. For the global ecosystem, Blackstone’s activity underscores that large‑scale private capital is now a primary driver of new capacity, influencing everything from site selection and power procurement to long‑term customer contracting.
