Firmus, the ‘Southgate’ AI data center builder backed by Nvidia, hits $5.5B valuation

April 7, 2026 · TechCrunch

An AI-focused infrastructure builder announced a higher valuation in the latest funding and planning cycle.

Firmus’ valuation update reflects how aggressively AI infrastructure firms are being capitalized as compute demand continues to rise.

The valuation also reflects market confidence in building power-forward data center projects around long-term AI growth assumptions.

Data center specialization around power, cooling, and location becomes increasingly tied to financing terms and execution credibility.

For AI operators, this strengthens the case that physical infrastructure now functions as a strategic moat and not merely a support function.
