Anthropic's $150 Billion Data Centre Plan for Australia: 1.4GW of AI Compute Set to Redraw Global Infrastructure Map

AI giant Anthropic, the $1 trillion company behind Claude, is planning a massive $150 billion data centre buildout in Australia. The plan, which would nearly double Australia's entire data centre industry capacity, signals a major shift in the global AI arms race and could make Australia a second home for training AI models .

A $1 trillion AI company has its sights on Australia not just as a market, but as a base for its global AI infrastructure. Anthropic, the tech giant behind the Claude AI model is in advanced discussions to procure at least 1.4GW of data centre capacity across the country, representing an estimated investment of up to $150 billion.

The scale of the plan is staggering. 1.4GW of capacity is roughly equivalent to the entire Australian data centre industry's capacity at the end of 2025. The company wants at least 1GW operational by mid-2027, a timeline that has data centre developers rushing to secure financing and grid connections.

"We're exploring adding local capacity through our third-party partners in Australia, using infrastructure already in place," an Anthropic spokesperson confirmed. "This is among the most consistent requests we hear from Australian enterprises and government agencies, particularly those with data residency requirements."

The move comes as Anthropic prepares for a blockbuster IPO estimated at more than $1.3 trillion. CEO Dario Amodei, who visited Australia in March to meet with politicians, financiers, and developers, has revealed the company's revenue has grown fivefold in the past six months to an annualized rate of about $72 billion.

The tender documents, sent to Australian data centre operators including CDC Data Centres, AirTrunk, Iren, and NextDC, set out an aggressive timeline. First-round proposals were submitted in March, and Amodei met with Treasurer Jim Chalmers in Canberra in early April, with final decisions expected within weeks. Anthropic may split the capacity across four or five providers, rather than awarding a single contract, with CDC Data Centres reportedly in line for the largest share of about 500MW.

"What decides whether investment of that scale proceeds is practical: firmed energy supply, the speed of grid connections, and planning approvals," warned Belinda Dennett, chief executive of industry lobby group Data Centres Australia.

The plan comes as the Australian government has made clear its expectation that data centre operators supply their own power and contribute to the wider grid. But securing 1.4GW of reliable, clean energy in a stretched grid will be a critical challenge. In a memorandum of understanding signed with the government in April, Anthropic committed to helping plan energy infrastructure, including "firmed renewables.”

Here is the question this project raises. Anthropic is fleeing the US data centre crunch, where community opposition and power shortages are stalling projects. But Australia's energy grid is already under pressure. When a $150 billion AI infrastructure plan depends on 1.4GW of new power, is Australia ready to deliver or will the same problems that chased Anthropic from the US resurface here?

The proposal has also sparked debate about the broader economic benefits of hosting AI data centres. Former minister Ed Husic has warned that some demand for data centres is driven by investor valuations rather than genuine AI capacity needs, and he noted the "hot potato" of energy and water consumption in the US is driving tech companies to seek Australian capacity. The government has repeatedly ruled out a text and data mining copyright exemption that Anthropic reportedly sought, insisting it will not change copyright laws to suit AI companies.

As Anthropic's $150 billion data centre plan moves toward a decision, The Silicon Review asks a final question. When a $1 trillion company wants to make Australia its second home for training AI, and the energy grid is the only thing standing in the way, will the country seize the opportunity to become a global AI hub or watch the chips fall elsewhere?

FAQ:

Q: What is the Australia-India uranium deal about?
A: Australia and India have finalised administrative arrangements enabling uranium exports to India for peaceful nuclear energy purposes. The deal allows Australian uranium to fuel India's civilian nuclear power programme under IAEA safeguards.

Q: When was the Australia-India nuclear cooperation agreement signed?
A: The Australia-India Nuclear Cooperation Agreement was signed in 2015. The administrative arrangements finalised this week implement that agreement.

Q: Why is this uranium deal significant for India?
A: India aims to install 100 gigawatts of nuclear power by 2047, but nuclear currently accounts for just three per cent of its electricity. Australian uranium can help India expand its clean energy capacity.

Q: Will Australian uranium exports to India be under safeguards?
A: Yes, the uranium exports will be exclusively for peaceful purposes and under International Atomic Energy Agency safeguards.

Q: Did Australia ban uranium exports to India before?
A: Australia historically refused uranium exports to India because India is not a signatory to the Nuclear Non-Proliferation Treaty. The 2008 Nuclear Suppliers Group waiver opened the door, and the 2015 bilateral agreement established the framework.
