Nvidia Backed Firmus IPO Tests Income as Yields Hit 5.1%
The AI buildout split in public this week. Nvidia backed Firmus Grid started marketing an ASX listing of about A$7 billion, while several US data center and power names delayed their own floats. The same session sent the 10 year Treasury yield up about 15 basis points to 5.11%, the highest close since 2007, and knocked the Nasdaq down 1.13%.
Firmus still wants an ASX listing
Firmus Grid, a data center operator backed by Nvidia (NVDA), began marketing a float on the Australian Securities Exchange. Reports put the raise near A$7 billion, which would rank among the largest Australian listings on record, behind only the Telstra sale in 1997.
The timetable in circulation is tight. Institutional books are slated to open around 6 October and close the next day. Retail bidding is sketched for mid October, with trading aimed at 22 October. None of that is a filed prospectus yet.
The business case is a 360 megawatt AI campus in Batam, Indonesia, using up to 170,000 Nvidia accelerators. Offtake talk has run as high as US$25 billion to US$30 billion of revenue over the first six years of the Nvidia partnership. Firmus has also been linked to a separate financing package of about US$10 billion, split between debt and equity, to buy more chips.
Public markets will not pay private round prices just because the chips are scarce. Nvidia is investor, supplier, and customer in this story. That loop can fund growth. It can also make the equity look circular once the shares have to clear a real book.
US data center floats stepped back
The contrast is the US calendar. SB Energy, the SoftBank unit behind a giant Ohio campus with OpenAI as the named tenant, pushed a planned September listing into later October after buyers balked at a valuation of US$50 billion or more. Holtec, a nuclear name pitching power for AI sites, paused its float. Aggreko, a power supplier that had leaned on data center demand, slowed its process too.
The spend plan is still huge. Big tech has already flagged more than US$1 trillion of infrastructure outlays, and some asset managers still talk about more than US$5 trillion of AI build cost by 2030. The money is not gone. The bid for unproven public vehicles is thinner.
Frontier labs are in the same queue. Anthropic has been discussed as a fall candidate. OpenAI has looked more like a 2027 story if it insists on a trillion dollar print. Infrastructure groups were supposed to be the simpler cash flow trade. This week they looked harder to list than the labs.
Yields jumped and the tape followed
Stocks opened as if they might drift. The S&P 500 (SPX) had been almost unchanged the prior session even as the Nasdaq 100 (NDX) caught a tech bid. Bond desks did not play along.
The 10 year yield rose about 15 basis points to 5.11%. Some prints tagged 5.12% and 5.14% before the close. That is the highest level since July 2007 and the largest one day jump since the April 2025 tariff shock. The 30 year yield added about 11 basis points to 5.40%. Five year notes cleared 5% for the first time since 2007 after a weak auction.
The tape mapped the rates move. The S&P 500 fell 0.75% to 7706. The Nasdaq dropped 1.13% to 26936. The Dow lost 0.68% to 51512. Energy was the only S&P sector in the green, up about 1%. Utilities fell about 2%. Travel names such as Expedia and Airbnb slid as much as 8%.
The spark was a fat activity print. US private sector output ran at a more than five year high in September, and oil snapped a five day slide with Brent up about 4% and crude back above US$100. Fed Governor Michael Barr said further policy adjustments are likely. October hike odds jumped from about 55% into the high 60s. Mortgage rates printed 7.12%.
Oil and storms hit the same tape
A five day oil drop ending on a 4% bounce is not a weather story, but the storm track is now in the same session. Prediction markets on 23 September put a major hurricane landfall in Mexico near 24% for Polo and a Hawaii landfall near 13% for future storm Nolo. Energy cash flow likes a bid in crude. Insurers and coastal REITs do not like landfall odds that high this late in the season.
Gold did not hedge the move. It dropped about 1.5% as real yields ripped and the dollar firmed. Growth data hot, oil up, bonds sold, duration assets marked down. Income stocks live in duration.
Alphabet and Amazon led the index lower. Nvidia can fund a private partner and still watch listed multiples compress when the risk free rate jumps 15 basis points before lunch.
What this means for income investors
Utilities just showed their beta to a 15 basis point yield shock. A 2% sector drop in one session is a reminder that defensive is a word, not a duration profile. REIT and other rate sensitive payers will reprice off the 10 year until that 5.11% print looks like a spike rather than a floor.
Energy was the cash flow sleeve that worked. A 4% bounce in Brent after five down days, plus a 1% sector gain, is the simple offset when the rest of the income book is fighting higher discount rates.
The Firmus listing tests whether public capital still wants AI infrastructure at private prices. If the ASX book fills at a full number while US floats wait, the message is local bid, not a green light for every data center equity. Income investors do not need to own the IPO. They need to watch whether the same yield that stalled those listings keeps lifting the hurdle rate on every utility, REIT, and pipeline payout already in the market.
