Firmus Lands Multi-Billion Deal for 18,400 Nvidia GB300 Chips

Australian AI infrastructure startup Firmus Technologies just locked in a multi-billion-dollar agreement to construct a massive data center in Melbourne. The facility will house 18,400 Nvidia GB300 chips — serious GPU firepower.

The customer? An unnamed global technology company. Firmus isn't saying who, but a deal this size narrows the field considerably.

The GB300 is Nvidia's next-generation AI accelerator, and stacking over 18,000 of them in a single facility signals enormous compute ambitions. That's not a training cluster you build for casual workloads.

For Firmus, this is a landmark moment. The company is positioning Australia as a legitimate player in global AI infrastructure — a market long dominated by US and European operators. Melbourne just became a very interesting dot on the global data center map.
