Nvidia-backed AI data center builder Firmus hits $5.5 billion valuation

Asian AI data center provider Firmus has raised $1.35 billion in just six months and reached a valuation of $5.5 billion. The company is backed by Nvidia, one of the biggest beneficiaries of the AI infrastructure boom. The industry has already nicknamed Firmus "Southgate" for its systematic approach to building data centers and dependable execution at every level.

Firmus operates in Asia, where demand for AI compute is growing faster than anywhere else. The region is becoming a key battleground for AI infrastructure: governments from Singapore to Japan are investing billions in sovereign compute capacity, while tech companies are actively looking for reliable partners to host GPU clusters. Firmus has carved out a niche as exactly that kind of partner: a specialized builder of data centers optimized for high-density AI workloads.

Nvidia's participation in the funding round is more than a financial investment. The GPU maker is actively putting money into infrastructure companies that speed up the rollout of its hardware. The partnership with Firmus gives Nvidia a direct channel into Asian markets, where demand for H100 and Blackwell accelerators far exceeds available supply. In effect, Nvidia is financing the construction of infrastructure that will consume its own products, a classic vertical integration strategy.

The pace of fundraising is impressive even against the backdrop of an overheated AI infrastructure market. Raising $1.35 billion in six months is a figure that used to be typical only of the largest American cloud providers. A $5.5 billion valuation puts Firmus on par with CoreWeave in its early stages. For comparison: in 2023 CoreWeave was valued at roughly $7 billion, before growing to $23 billion by the time of its IPO.

The "Southgate" nickname refers to Gareth Southgate, the former England national football team manager, who was valued for consistent results and methodical work rather than flashy tactical gambles. Applied to the data center business, it is the highest compliment: large customers prefer partners who build predictably, do not miss deadlines and keep their word on operational metrics. In a world where data center construction has become the bottleneck for the entire AI industry, a reputation as a reliable contractor translates directly into billion-dollar valuations.

The Asian AI data center market is undergoing a structural shift. American hyperscalers have historically dominated: Amazon Web Services, Microsoft Azure, Google Cloud. But data sovereignty requirements, energy constraints in Western countries and local governments' political desire to keep AI infrastructure under national control are creating lasting demand for regional players. Firmus has positioned itself squarely in this long-term trend.

Investment in AI infrastructure is reaching all-time highs in 2025–2026. According to analyst estimates, more than $300 billion was invested globally in building and upgrading data centers in 2025 alone. Asia is receiving a growing share of that spending, from 25 to 30% by various estimates, and competition for the role of regional leader in data center construction is only intensifying.

Firmus's rapid valuation growth and Nvidia's strategic backing are another signal to the market: the infrastructure layer of AI remains one of the most attractive sectors for capital. While the broader audience debates language models and applications, smart money is building data centers. And companies like Firmus will make money regardless of whose model ultimately wins the race for dominance.
