KKR and a group of founding investors on Thursday launched Helix Digital Infrastructure, a new company capitalized with more than $10 billion to underwrite the build-out of AI-focused data centers. The initiative aims to provide funding and operational expertise for the rapid expansion in compute facilities required to support advanced AI workloads.
Anchor commitments to Helix come from the Kuwait Investment Authority, chipmaker Nvidia and power company Vistra. The platform will be led by Adam Selipsky, who stepped down as chief executive of Amazon Web Services in May 2024 after overseeing a period in which AWS doubled both sales and operating profit since his 2021 appointment.
KKR said Nvidia will lend its design expertise to Helix’s efforts to construct AI-optimized data centers, while Vistra will serve as the preferred electricity provider for the platform’s deployments. KKR also noted Helix can accept additional institutional investors after the founding commitments are finalized. The firm’s infrastructure division manages over $100 billion in assets, including more than $70 billion allocated to digital and power investments.
The announcement comes amid a surge in U.S. data-center construction that industry participants say has strained local power supplies and contributed to shortages in electronic components. Those supply constraints and rising project costs have slowed the pace at which companies can bring new facilities online - facilities that are seen as critical to major technology companies’ AI plans.
KKR framed Helix as a response to those pressures. As Selipsky put it: "Large users of digital infrastructure have an urgent need to reduce complexity and unlock new capacity."
Private equity interest in AI infrastructure has been increasing. In a separate development earlier in the week, Apollo and Blackstone announced plans to finance a $35 billion expansion of AI capacity for Anthropic, using custom chips from Broadcom as part of a new partnership. That deal was cited by market observers as another example of private capital stepping into large-scale AI infrastructure projects.
KKR’s statement indicated Helix will target the financing and development bottlenecks that have emerged as cloud and AI compute demand accelerates, with founding investors providing both capital and technical or utility partnerships. The long-term structure and specific allocation of completed investments will depend on the closing of the founding commitments and any additional institutional backers that Helix brings on board.
Key points
- Helix Digital Infrastructure launched with over $10 billion in committed capital to finance AI-focused data-center construction.
- Anchor investors include the Kuwait Investment Authority, Nvidia and Vistra; Nvidia will advise on data-center design and Vistra will be the preferred power provider.
- KKR’s infrastructure platform manages over $100 billion, including more than $70 billion in digital and power assets, and Helix may add more institutional investors post-closing.
Risks and uncertainties
- Power supply constraints in regions with concentrated data-center construction may slow project timelines - affecting the energy and infrastructure sectors.
- Shortages of electronic components could delay facility build-outs and increase costs - impacting hardware suppliers and construction timelines.
- Rising project costs may require continued private capital involvement; the scale and terms of future financings are uncertain and could influence returns for investors in infrastructure and digital assets.
