Poolside Data Center Capex and Sites
Poolside partnered with CoreWeave in October 2025 on Project Horizon, a 2GW West Texas campus at Longfellow Ranch structured in eight 250MW phases with a 15-year lease on the initial 250MW phase and a 500MW expansion option. CoreWeave subsequently ended the 2GW deal, leaving a $2 billion funding gap, with power procurement challenges cited. Poolside was reported raising $2 billion at a $14 billion valuation after $500 million at $3 billion in 2024, and Nvidia separately agreed to invest up to $1 billion.

The figure beside each provider is its count of named sites in the atlas.
Part of the North American Data Center Capital Atlas, refreshed every Tuesday, Thursday and Saturday. Site commitments overlap reported capital expenditure and overlap one another, so this page shows each figure as its source states it and never adds them 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.
