What Happened

Firmus, a Singapore-headquartered AI data centre developer founded in 2019, is seeking up to $5bn in its listing on the Australian Securities Exchange, according to Bloomberg. The raise would rank among the ASX's largest floats.

The valuation trajectory is steep: $5.5bn in April 2026, climbing past $10.5bn by August. Investor meetings reportedly began in mid-September, with Australian roadshows to follow. No pricing, listing date, or free float percentage has been announced.

The catalyst for the valuation jump appears to be a multi-year OpenAI compute contract signed last week across two Malaysian sites. The contract value was not disclosed, but it made OpenAI the anchor customer and pushed Firmus past 900MW of contracted capacity. In June, the company also committed to a 360MW site in Batam, Indonesia, with access to 170,000 Nvidia accelerators through 2028 and an expected $25bn to $30bn in committed offtake over its first six years. That site is scheduled to go live in Q1 2027.

Firmus's flagship Australian project, Project Southgate, plans 1.6GW across five locations by 2028, starting in Launceston, Tasmania. The initial build is costed at $4.5bn against a full programme estimated at $73.3bn. A $10bn debt facility led by Blackstone in February is funding the early stages.

Why It Matters

The critical detail: only two of seven planned AI factories are currently operational. Everything else — the OpenAI contract, the Batam site, Project Southgate — is contracted, committed, or announced. The distance between a signed offtake agreement and a delivered megawatt is where data centre developers historically encounter execution risk, supply chain delays, and cost overruns.

Firmus is asking public markets to fund that crossing. The $10.5bn valuation is effectively a judgement on 900MW of contracts rather than on the two sites currently drawing power. Whether that valuation holds through the roadshow will set a benchmark for how public markets price contracted-but-undelivered AI infrastructure.

The broader context matters too. Firmus is building into a Southeast Asian region planning four times its current data centre capacity, with Malaysia carrying most of a 6GW pipeline. Australia has also tightened rules: since July 2026, AI data centres are expected to put back more power than they draw, funding new renewable generation. Firmus's liquid-cooled design — marketed as using a third less energy and almost no water — positions it better than most to meet that requirement.

This float also fits a pattern. AI infrastructure companies are racing to public markets: Lambda is raising pre-IPO capital, Crusoe reportedly sought $3bn at a $30bn valuation, and OpenAI's revenue run rate has topped $40bn ahead of its own IPO. Firmus is the Southeast Asian entry in that wave.

Who Is Affected

AI startups and enterprises sourcing compute in Asia-Pacific should track Firmus's buildout timeline. New capacity in Malaysia and Indonesia could diversify GPU availability beyond US-based providers, but only two sites are live today.

GPU cloud customers and infrastructure investors will be watching the ASX pricing closely. If the $10.5bn valuation holds, it signals that public markets are willing to pay for contracted capacity, not just operational assets. If it gets repriced downward, it could cool the broader AI infrastructure IPO window.

Competitors building data centres in Australia and Southeast Asia face a new publicly traded comparable for valuation and capacity claims. The disclosure requirements of a public listing will also reveal margins, customer concentration, and execution timelines that private competitors have been able to keep opaque.

Strategic Implications

AI startup founder: If you're sourcing compute in Asia-Pacific, Firmus's Malaysia and Indonesia sites could offer an alternative to US-based GPU cloud providers — but plan around the Q1 2027 Batam go-live at the earliest. Don't build dependencies on capacity that isn't operational.

Developer/operator building with AI APIs: The OpenAI anchor contract suggests Firmus's infrastructure meets hyperscaler standards. If you operate inference workloads in the region, the 170,000 Nvidia accelerators planned for Batam through 2028 could be a meaningful backend — once delivered.

Non-technical business owner evaluating AI tools: This float signals accelerating AI infrastructure investment in Southeast Asia, which could eventually reduce latency and costs for AI services in the region. No immediate action needed, but it's a directional signal on where compute capacity is heading.

What to Watch Next

Monitor the ASX listing pricing and free float percentage when announced — that will reveal whether the $10.5bn valuation survives public market scrutiny. Also watch for any disclosure of the OpenAI contract value, which has been conspicuously absent and would materially affect how the market prices Firmus's revenue visibility.

Frequently Asked Questions

Q: What is Firmus and why is its ASX float significant?

A: Firmus is an AI data centre developer building infrastructure across Southeast Asia and Australia. Its $5bn ASX float at a $10.5bn valuation would be one of the largest in the exchange's history and tests whether public markets will pay premium valuations for contracted-but-not-yet-operational AI compute capacity.

Q: How much of Firmus's planned capacity is actually operational?

A: According to The Next Web, only two of seven planned AI factories are currently running. The remaining capacity — including the OpenAI-contracted Malaysian sites and the Batam, Indonesia facility — is contracted, committed, or announced but not yet operational.

Q: Who are Firmus's main backers and customers?

A: Firmus's backers include Nvidia and Blackstone, with Blackstone leading a $10bn debt facility in February 2026. OpenAI is the anchor customer following a multi-year compute contract signed in September 2026.
