MGX sits at the intersection of the three largest structures in the atlas. It is one of the initial equity funders of Stargate alongside SoftBank, OpenAI and Oracle, a program targeting $500 billion of US AI infrastructure investment over four years with $100 billion deployed immediately, beginning in Texas. It is a founding partner of the AI Infrastructure Partnership ($30 billion equity, up to $100 billion with debt) and a co-acquirer of Aligned Data Centers at a $40 billion enterprise value, closed July 21, 2026, covering 51 campuses and 6.4GW. It also participated in xAI's $6 billion Series C.

Capital figures come from the [Capital Atlas](https://savrn.com/data-center-capital-atlas), refreshed every Tuesday, Thursday and Saturday. Site commitments overlap reported capital expenditure and overlap one another, so each figure appears as its source states it and none are added into a single deployment number. Informational, not investment advice.

The SAVRN reference set

## Seven references, one system

Capital, delay, policy, water, grid, permits and scarcity are one system seen from seven sides. Each reference is primary-sourced, refreshed on a schedule, and links into the others, so a project can be followed from the money committed to the docket that stopped it.
