OpenAI becomes anchor customer of Firmus, which crosses 900 MW of contracted capacity before IPO

Two Malaysian sites of the Nvidia-backed Australian operator are reserved for OpenAI in an undisclosed multi-year deal, just months before an expected IPO in Sydney.

The agreement announced on 8 September 2026 concerns dedicated computing capacity, taken from two AI Facts that Firmus operates in Malaysia. OpenAI takes on the status of anchor client, which is not only a symbolic value in this business: it is the long-term commitment of a reference lessee that allows to finance and trigger the construction of the following tranches. Financial terms have not been communicated.

For the Australian operator, the effect on the carnet is immediate: the combined capacity of all customers now exceeds 900 megawatts, spread over seven sites in four countries — Australia, Singapore, Indonesia and Malaysia. Firmus has Nvidia as one of its supporters, and its last release has valued it at over $10.5 billion.

The timetable is not indifferent. The agreement is signed prior to an introduction to the stock exchange deemed likely in the year, which could be one of the largest Australian operations of the recent period. It also illustrates the geography of the race to calculate: instead of concentrating everything in the United States, OpenAI reserves power in Southeast Asia, where land, electricity and connection times are less tense.
