✦ Helix and Being the Preferred PartnerThin moat

Alongside the Meta power purchase agreements, Vistra agreed to be the preferred power partner for Helix Digital Infrastructure, a newly formed company designed to develop infrastructure for AI-oriented hyperscalers¹.

That is a different kind of arrangement from everything else on these pages. It is not a contract for a quantity of power at a price; it is a position in a company being built to develop the data centres that will need power. Preferred means first call, not obligation.

The strategic reasoning is easy to follow. Vistra's problem is not that it lacks generation; it is that the number of counterparties able to sign a twenty-year agreement for a gigawatt of firm power is very small, and they are being courted by every generator in America. Being embedded in the entity that develops the sites is a route to the next contract that does not depend on winning a competitive process.

It also hedges the behind-the-meter risk the Major Clients pages describe. If the hyperscalers' preferred structure becomes generation co-located with compute rather than grid supply, a preferred partnership with a developer is a way to be inside that structure rather than displaced by it.

The honest assessment is that this is optionality, not earnings. There is no disclosed volume, price or term, Helix is newly formed, and preferred-partner status is worth exactly what the partner decides it is worth.

The measure is whether a second wave of contracts arrives through this channel rather than through the open market — which would say the relationship works, and which nothing yet demonstrates.
