KKR, Nvidia and Vistra Launch $10 Billion AI Infrastructure Platform Helix

KKR has launched a new AI infrastructure company with more than $10 billion in long-duration capital commitments, joining with the Kuwait Investment Authority, Nvidia and Vistra (NYSE: VST) to finance and coordinate the data centers, power and connectivity needed by hyperscalers.

The new company, Helix Digital Infrastructure, is designed to act as a single coordination point for large technology customers as they race to add capacity for artificial intelligence workloads. The platform will seek to invest in and manage hyperscale data centers, power generation, transmission and distribution infrastructure, and fiber and connectivity assets, KKR said Thursday.

Helix will be led by Adam Selipsky, the former chief executive officer of Amazon Web Services. Waldemar Szlezak, KKR’s global head of digital infrastructure, will serve as Helix’s chief investment officer.

The launch underscores how AI infrastructure development is increasingly becoming a power and financing challenge, rather than only a data-center construction cycle. Training and deploying large AI models requires large campuses with access to reliable electricity, grid interconnections, cooling, network connectivity and long-term capital. Those requirements have created bottlenecks for hyperscalers and cloud providers trying to bring new capacity online quickly.

Nvidia will serve as a strategic partner to Helix, supporting deployment of infrastructure aligned with its DSX AI factory platform. KKR said the partnership is intended to improve tokens per watt, lower total cost of ownership and accelerate “time to first token” for Helix-backed projects.

Vistra will be the preferred power provider for Helix investments. The Texas-based power company operates across 18 states and Washington, D.C., and has become one of the most visible beneficiaries of the AI-driven power demand theme. Vistra said its existing generation fleet could help Helix deliver near-term power solutions while also supporting new generation development and grid expertise.

Jim Burke, Vistra’s president and CEO, said power generation and grid interconnections are “critical gating factors” for AI infrastructure deployments. He added that Vistra has executed more than 5,000 megawatts of power purchase agreements with hyperscalers.

For KKR, Helix extends a broader push into digital and power infrastructure. The firm said its global infrastructure platform includes more than $100 billion in infrastructure assets under management and more than $70 billion invested across digital and power assets. KKR’s anchor investment in Helix will be funded through its balance sheet and other managed vehicles.

The structure also reflects a broader shift in the AI infrastructure market. Large cloud and AI companies are increasingly looking for repeatable development models that combine capital, site control, power procurement and execution capability, as the size of AI campuses moves from hundreds of megawatts toward gigawatt-scale projects.

KKR said Helix will be open to additional eligible institutional investors after the founding commitments close.

“Large users of digital infrastructure have an urgent need to reduce complexity and unlock new capacity,” Selipsky said. “Helix combines significant long-term capital with the capabilities and expertise to deliver holistic AI infrastructure solutions with speed and scale.”

The launch comes as private capital managers, power companies and chip suppliers are moving deeper into the AI infrastructure supply chain. The rapid growth of AI workloads has increased demand for not only GPUs and cloud capacity, but also power plants, transmission access, substations and fiber networks — assets that historically sat outside the core business of many hyperscalers but are now central to their expansion plans.
