KKR has launched Helix Digital Infrastructure, a standalone company backed by more than $10bn in committed capital, to design, build, own and operate the physical infrastructure that AI depends on.
The company will be led by Adam Selipsky, who ran Amazon Web Services from 2021 to 2024, during which time he doubled the business past $100bn in annual revenue and oversaw the early surge in GPU-driven computing demand. He joined KKR as a senior adviser in September 2025. Now he runs the thing.
Waldemar Szlezak, KKR's global head of digital infrastructure, will serve as chief investment officer.
What Helix does
Helix is not positioning itself as a data centre operator. It is positioning itself as the single counterparty for hyperscalers that need everything: land, power generation, transmission, networking, cooling and data centre space delivered as one integrated package.
The pitch addresses a specific bottleneck. Hyperscalers can design AI systems. They struggle to secure the physical prerequisites, power connections, planning approvals, cooling infrastructure and fibre connectivity, fast enough to match their deployment timelines. Two thirds of tracked US data centre projects are not yet under construction. The constraint is not capital. It is execution.
Helix is designed to solve the execution problem by owning the full stack of physical infrastructure rather than brokering individual components.
Capital behind it
KKR has secured commitments from a sovereign wealth fund and strategic partners, with additional fundraising planned. The $10bn is the starting point, not the ceiling.
The firm has been building towards this for years. KKR co-owns data centre operator CyrusOne with BlackRock's Global Infrastructure Partners. It has a $50bn AI data centre joint venture with Energy Capital Partners. It backed a co-located power generation and data centre facility in Bosque County, Texas, with CyrusOne and Calpine.
Helix consolidates those threads into a single operating platform. KKR's broader real assets business manages $179bn, and digital infrastructure is now the fastest-growing segment within it.
Why Selipsky matters
Hiring a former AWS CEO to run an infrastructure company is a statement about who the customer is. Selipsky understands hyperscaler procurement, lease economics and the political reality of permitting power-hungry sites. He spent years on the demand side. Now he is building the supply.
The appointment also signals that Helix intends to operate as a technology company with financial backing, not a financial company with technology assets. The distinction matters for how hyperscalers evaluate partners.
Tens of billions of dollars
Private equity has committed tens of billions to data centre infrastructure in the past 18 months. Blackstone, Apollo, Brookfield and KKR are all competing for the same assets: land with power, sites with permits, operators with hyperscaler relationships.
Helix's differentiation is vertical integration. Rather than buying existing data centres and extracting rent, it plans to build the entire infrastructure stack from scratch, matched to hyperscaler specifications.
Whether $10bn is enough to compete with hyperscalers that are collectively spending $800bn a year on capex is the obvious question. The answer is that Helix is not competing with them. It is building what they need and cannot build fast enough themselves.
