Who owns KKR Helix C L.P. (the Helix Fund)

KKR Helix C L.P. (the Helix Fund) - Profile

KKR Helix C L.P., referred to as the Helix Fund, is a Delaware limited partnership formed in 2025 and managed by affiliates of KKR and Co. Inc., with its offices at 30 Hudson Yards in New York and KKR Helix C Associates L.P. as general partner. It is an open ended investment fund and one of the vehicles behind Helix Digital Infrastructure, the company launched in June 2026 to build integrated artificial intelligence infrastructure for hyperscale cloud customers. The fund invests in and manages assets that enable AI workloads: hyperscale data centre development and operations, baseload and flexible power generation, transmission and distribution infrastructure, and fibre and connectivity networks. Helix Digital Infrastructure is led by Adam Selipsky, the former chief executive of Amazon Web Services, with Waldemar Szlezak of KKR as chief investment officer, and launched with more than 10 billion dollars of long duration capital commitments, Nvidia as a cornerstone technology partner and Vistra as preferred power provider.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

• Vistra Corp., as of 30 Jun 2026. Q2 2026 10-Q Note 7 (Equity Method Investment): in June 2026 Vistra entered a limited partnership agreement governing KKR Helix C L.P., an open-ended fund managed by affiliates of KKR & Co. Inc. that invests in AI-enabling infrastructure including hyperscale data center development, baseload and flexible power generation, transmission/distribution and fiber. Vistra is a founding investor and committed up to $1.0 billion total: an initial $500 million commitment plus an additional $500 million contingent on the Helix Fund meeting commercial power supply milestones for Vistra's existing generation assets, or at Vistra's election. Vistra's interest meets the significant-influence criteria under GAAP and is accounted for under the equity method. As of June 30, 2026 the $500 million initial commitment 'remains callable by the fund's general partner' and had not yet been called or funded (10-Q Liquidity and Capital Resources section), so the carrying value and cash invested were both $0 as of the report date. Neither the 10-Q nor any other filing found discloses the Helix Fund's total size or Vistra's resulting percentage ownership interest in the fund, so shares and pct_of_target are null rather than estimated. This is a real, named, disclosed equity-method stake, just not yet funded or sized as a percentage. source
