What is NVIDIA’s Vera Rubin platform?

Vera Rubin is NVIDIA’s next-generation AI factory platform, confirmed in full production at GTC Taipei on 31 May 2026. It is the third generation of NVIDIA’s MGX rack-scale design, built as five purpose-built racks operating as a single system for agentic AI workloads, and NVIDIA states it delivers 10x agent throughput at scale over the previous Grace Blackwell platform. The launch also brought Spectrum-X Ethernet Photonics, a co-packaged-optics switching generation, into production. Production shipments begin from the northern autumn of 2026, placing it one step behind the GB300 systems being deployed now.

Which Australian companies are in NVIDIA’s Vera Rubin launch cohort?

NVIDIA named eleven cloud providers as adopters of Confidential Computing on Vera Rubin, and two of them, Firmus and IREN, were founded in Australia. Firmus is building AI factories on Australian soil through Project Southgate and is an NVIDIA equity investee. IREN was founded in Sydney in 2018 but runs most of its compute in the United States and Canada, with Australian operations targeted from 2028. The other nine named adopters are CoreWeave, GMI Cloud, IBM Cloud, Lambda, Microsoft Azure, Nebius, Nscale, SpaceXAI and Vultr.

Is Firmus listing on the ASX?

Firmus is preparing an ASX initial public offering in mid-2026, reportedly seeking around A$2 billion. The company reached a US$5.5 billion valuation in its April 2026 equity raise and holds a US$10 billion debt facility led by Blackstone and Coatue. A successful float would rank among the larger technology listings in Australian market history and would give domestic investors a pure-play position in AI infrastructure. Firmus is building Project Southgate with CDC Data Centres and NVIDIA, targeting 1.6GW of capacity by 2028. Timing and final raise size should be confirmed against the company’s prospectus when lodged.

What does NVIDIA GTC Taipei mean for Australian data centres?

GTC Taipei confirmed an annual platform cadence that raises both the opportunity and the cost for Australian operators. Australia sits on the deployment side of the Vera Rubin supply chain rather than the manufacturing side, so the local advantage is in renewable power, land and sovereign hosting rather than silicon fabrication. The annual refresh from GB300 to Vera Rubin raises the capital bar, which is part of why Firmus and Sharon AI are listing in 2026. NVIDIA building Confidential Computing into the platform also aligns the global roadmap with Australia’s regulated-workload and sovereignty agenda.

A frontier launch cohort with two Australian names in it

NVIDIA used GTC Taipei to confirm that Vera Rubin is ramping into full production. The 31 May announcement was a supply-chain and platform story first, with 150 Taiwanese partners and more than 350 factories named as building Vera Rubin systems.

Within the platform’s security section, NVIDIA listed eleven cloud providers as adopters of Confidential Computing on Vera Rubin: CoreWeave, Firmus, GMI Cloud, IBM Cloud, IREN, Lambda, Microsoft Azure, Nebius, Nscale, SpaceXAI and Vultr. Two of those eleven, Firmus and IREN, were founded in Australia. Confidential Computing is the hardware layer that encrypts data in use and provides tamper-proof attestation across a rack, and it is aimed at regulated, government and mission-critical workloads. That is the segment Australia’s sovereign AI agenda is built around, and the segment local operators have been positioning for since the government published its data centre expectations in March.

Sitting in that cohort next to CoreWeave and Azure tells the market that Australian-founded operators are inside the first wave for the platform that follows GB300, not a cycle behind it. For Firmus, it compounds an existing relationship: NVIDIA is an equity investor, and a DGX Cloud region is committed at the company’s Melbourne campus. We covered the broader platform shift in our NVIDIA GTC 2026 recap, and the rise of this operator class in our neocloud market report.

What Vera Rubin is, and when it lands

Vera Rubin is NVIDIA’s third generation of MGX rack-scale systems and its largest POD-scale design to date, built as five purpose-built racks operating as one machine for agentic workloads. NVIDIA puts agent throughput at 10x the Grace Blackwell platform at scale. The launch also brought Spectrum-X Ethernet Photonics into production, a co-packaged-optics switch generation NVIDIA credits with 5x better power efficiency, which is the kind of figure that carries weight in a grid-constrained market like Australia’s.

Production shipments begin from this northern autumn, so 2026 is a two-platform year locally. GB300 is arriving now, with Firmus due to bring roughly 18,500 GB300 GPUs online at Southgate Melbourne, and Vera Rubin sits one step behind it on an annual cadence. That cadence is the structural point for Australian operators. Staying on frontier silicon now means refreshing roughly every year, and refreshing every year means raising capital at a pace only a handful of local balance sheets can sustain.

Firmus: the on-soil anchor

Firmus carries the weight of Australian capability that is physically built here. Project Southgate, run with CDC Data Centres and NVIDIA, targets 1.6GW of AI factory capacity across Tasmania, Melbourne, Sydney, Canberra and Perth through 2028. The alliance has set a A$4.5 billion first-stage investment, scaling to a headline A$73.3 billion, with first stages under construction in Tasmania and Melbourne and Southgate Melbourne anchored by roughly 18,500 GB300 GPUs. The design targets a PUE of 1.10 and more than 99% less water use than conventional builds, powered entirely by renewable energy.

Firmus has a US$10 billion debt facility led by Blackstone and Coatue, and reached a US$5.5 billion valuation in its April 2026 raise. It is preparing an ASX listing in mid-2026, reportedly seeking around A$2 billion, which would rank among the larger technology floats in Australian market history and would give domestic investors direct access to a pure-play AI infrastructure operator.

IREN: Australian-founded, compute mostly offshore

IREN was founded in Sydney in 2018 and keeps its headquarters at 55 Market Street, which is why it counts as Australian-founded on the Vera Rubin list. Its compute, though, runs largely in the United States and Canada, and its Australian operations are targeted from 2028. IREN is Nasdaq-listed and has scaled from bitcoin mining into AI cloud at speed.

So the platform credential is real, but the megawatts behind it are offshore for now. For an Australian audience the distinction is worth holding: IREN shows that an Australian-founded company can reach NVIDIA’s frontier cohort, while Firmus shows frontier capability landing on Australian soil.

Sharon AI and the race to the ASX

Sharon AI listed on the Nasdaq in February 2026 under the ticker SHAZ, and its board has since approved a dual listing on the ASX through CHESS Depositary Interests, which the company expects to complete before the end of June 2026, with Macquarie and Canaccord Genuity managing the float. On the infrastructure side, Sharon AI is deploying NVIDIA Blackwell Ultra capacity inside NEXTDC facilities, including a Cisco Secure AI Factory at NEXTDC’s S3 in Sydney, and has signed a 50MW expansion with NEXTDC targeting more than 20,000 GPUs.

Both Firmus and Sharon AI are set to trade on the ASX in 2026, which gives Australian institutions and retail a listed way to take a position on domestic AI infrastructure.

What GTC Taipei means for Australia

First, Australia sits on the absorption side of this roadmap, not the build side. The Vera Rubin supply chain is anchored in Taiwan across 150 partners and more than 350 factories, so the local opportunity is in deploying and operating frontier systems rather than manufacturing them. That is where Firmus, Sharon AI and a growing operator field are positioned, and it is why power and land, rather than fabrication, are the gating inputs locally.

Second, the platform cadence raises the capital bar each year. An annual refresh from GB300 to Vera Rubin and beyond means operators must keep funding new silicon to stay current, which favours the balance sheets that can reach billions at a time. Firmus answering with a US$10 billion debt facility, and Sharon AI stacking US$770 million in non-dilutive capital and billion-dollar offtake agreements, are both responses to the same pressure. The ASX listings are the next funding step in that sequence.

Third, the sovereignty layer is now a frontier feature rather than a local add-on. NVIDIA building Confidential Computing into Vera Rubin and naming sovereign-focused operators as early adopters aligns the global roadmap with Australia’s regulated-workload agenda. For operators chasing government and financial-services demand, the hardware now does part of the compliance argument for them. That sits alongside the question of whether Australia can convert this into share, which we examined in our analysis of the 12-to-18-month window to capture the AI infrastructure boom.

What to watch

The Firmus ASX listing is the near-term marker, with a mid-2026 timeline and a reported raise near A$2 billion. Sharon AI’s CDI admission to the ASX is expected before the end of June 2026. On the platform side, the first Australian Vera Rubin orders will show which local operators move from the GB300 generation to the next one without skipping a cycle, and shipments from this northern autumn will set the pace.
