Who owns Stateline Power, LLC

Stateline Power, LLC - Profile

Stateline Power, LLC is a United States power generation venture formed in April 2025 to supply off grid electricity to a large artificial intelligence data centre campus, the COLOSSUS II site on Stateline Road in Southaven, Mississippi, which sits outside the reach of timely utility interconnection. It owns a fleet of natural gas fired mobile turbines and related equipment that it rents to the data centre operator under a master equipment rental agreement, originally sized at about 500 megawatts and upsized to roughly 900 megawatts on a seven year initial term, with up to 550 million dollars of senior secured term debt arranged to fund the build. Solaris Energy Infrastructure holds the majority interest and contributed turbine progress payments and prefunded costs valued at about 86 million dollars, and it also operates and maintains the fleet, while the data centre owner contributed a matching 86 million dollars in cash for the remainder. The turbines are the subject of a Clean Air Act suit filed in April 2026 by the NAACP over their permitting in Mississippi.

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.

• SpaceX, as of 31 Dec 2025. Value is the carrying value of the equity method investment at 31 Dec 2025, which equals SpaceX's initial $86 million cash contribution. Stateline is a variable interest entity in which SpaceX is not the primary beneficiary, so it is not consolidated: SpaceX accounts for it under the equity method. The Q2 2026 10-Q does not restate the Stateline carrying value separately, so no 30 Jun 2026 figure is available. source
