Why the Firmus stock market listing might not add up

AU Edition - Today's top story: Can data centre company Firmus live up to its blockbuster $43 billion listing value? Why some investors doubt it

October 8, 2026

AU Edition

 

It’s not often a new company listing on the stock exchange makes headlines. But data centre builder Firmus, which is about to launch the largest new listing since Telstra in the late 1990s, is attracting attention for all the wrong reasons.

First, there’s the eye-watering valuation of up to $43 billion, which has almost tripled in a matter of months despite a lack of financial information. We should get details about revenues and debt levels later today, but so far Firmus has built only 5% of its promised data centre capacity.

More importantly, Firmus encapsulates the deep divide between AI true believers and those who worry about a potential bubble, fuelled by the close relationships between investors, suppliers and customers. As Marta Khomyn explains, who’s right will matter for all of us with savings in Australia’s super funds.

Why most health apps are biased even before their first lines of code are written

Beige tones and knit throws? No, we’ve got Scandinavian design all wrong

Nina Hillenberg, Torrens University Australia

Scandinavian design is rooted in a philosophy that seems to make life easier. But it’s been turned into a bland colour palette.

Your Say

Thank you for the informative story on what’s happening in everyday retail and service transactions following the banning of card surcharge fees. What I find strange is that no business factors the cost of using cash into its pricing. Requiring employees to handle cash means less safety for them – our local café was held up a few years ago, to the great distress of its young employees, and went cash-free as a result. But cash also adds transaction time: the time taken for the customer to produce and count out the money, for the employee to count out the change, to count the cash in the till at the end of the day, to take the day’s cash to the bank, and to fill the till each morning with the cash float. On top of that, most banks charge fees for depositing cash. With wages making up the bulk of most business costs, why should those paying by card, which usually takes only a few seconds per transaction, have to subsidise all these daily costs?

Thanks for traveling to Turkey for the [UN climate] summit, and for asking what I’d like to know about the meeting. With Australia a main negotiator I’m wondering how we will be explaining the fact that we’re not only not meeting any climate goals but instead keep allowing new fossil fuel projects. The government approved more than 35 new or extensions of coal, oil and gas developments and we’re not even sorry about this. Keeps me guessing what the Australian government actually fails to understand in the simple calculations of cause and effect. Best regards and good luck for Turkey.
