VNET Group, a Beijing carrier-neutral data-center operator that rents cabinets and whole wholesale halls to Chinese cloud providers, delivered the kind of quarter its buildout thesis requires. Wholesale colocation revenue rose 29.3% year on year to RMB1.10bn, total net revenue rose 14.2% to RMB2.78bn — about $409.5m — and the company disclosed a 345-megawatt order from a single cloud provider, taking wholesale wins for the year to 862 megawatts. It also announced a strategic agreement with the battery maker CATL to build gigawatt-scale compute-and-energy facilities.

The stock fell roughly 17% on the session.

The rate, not the rent

It did not fall alone. Applied Digital lost 8.2%, Keel Infrastructure 15.5%, WhiteFiber 11.1%, SharonAI 10.6% and GDS Holdings 4.6% on the same day. The common event sat outside the buildings: the 30-year Treasury yield topped 5.33%, a 19-year high, on inflation and federal-spending worries. For companies that fund halls with project debt before a tenant pays rent, the discount rate is the business. Alphabet's recent 30-year paper priced near 6.4%, and hyperscalers have issued $159bn of bonds this year, up 47%.

The rest of the month tells the same story in reverse. Over 30 days the six averaged a 6.8% gain. Strip each name's two best sessions and all six turn negative — an average of -19.3%. One of those sessions is shared: on 30 July every one of them rose between 8% and 28%, the day Microsoft's cloud guidance lifted the Nasdaq 100 by 3.36% and the Philadelphia semiconductor index by 8.2%. Stretch the window to three months and the group is already down 6.7%.

Six businesses, one slogan

What they share is a customer story — the four largest cloud buyers plan up to $630bn of capital spending in 2026, against $388bn last year. What they do not share is an end market.

GDS, China's largest carrier-neutral operator, is the leading contract story and the lagging income statement. It booked a record 260 megawatts in the June quarter, doubled its full-year target to 1 gigawatt and grew backlog to 757 megawatts. Reported revenue growth nonetheless slowed from 23.6% to 6.2%, gross margin fell from 33.6% to 19.5%, and management guided monthly revenue per cabinet down about 3% by year-end as legacy contracts reprice. It trades at 14.4 times trailing EV/EBITDA and 1.44 times book.

VNET is the diverging one. At 9.4 times trailing EV/EBITDA it carries the cheapest anchor in the group, guides to 2026 revenue growth of 15.6% to 18.6%, and has 516 megawatts scheduled for delivery over twelve months. It is still loss-making, and its cash gross margin slipped to 41.8% from 43.6%. It is down 24.7% over three months.

Applied Digital, the former bitcoin miner leasing AI halls in Ellendale, North Dakota, grew fiscal-2026 revenue 183.7% to $611.3m and still lost $236.4m at the operating line. The mix matters: of $258.7m in the May quarter, only $44.1m was base rent, while $152.4m was one-time tenant fit-out work. Gross margin fell from 42.5% to 15.7%, and diluted shares rose 42%. Against roughly $36bn of contracted lease revenue, its own filings schedule $451m as due in the coming year, versus $5.0bn of debt. It trades at 64.0 times trailing gross profit, 44.8 times forward.

Keel Infrastructure, the renamed Bitfarms, has switched off mining before switching on leasing. Revenue fell 60.9% to $30.4m, gross profit was minus $86.8m, and not one high-performance-computing lease has been signed; management targets three this year. It is the only name here whose forward price-to-sales multiple, 17.1 times, sits above its trailing 12.6 times — it gets more expensive as it falls, because consensus has revenue dropping another 59.1%.

SharonAI, a two-year-old graphics-processing-unit cloud with 25 employees, reported $1.93m of quarterly revenue against a $2.41bn market value — 780 times trailing sales. Its case rests on 212 megawatts secured, $8.8bn of announced contract value and a six-year NVIDIA agreement worth up to $4.88bn. Material revenue is not expected before the fourth quarter.

WhiteFiber, spun out of miner Bit Digital, is the smallest and the plainest: revenue of $28.8m, up 54%, adjusted EBITDA of $5.5m, half of its 40-megawatt North Carolina site billing, and $540m of new multiyear cloud contracts. At 25.5 times trailing and 13.3 times forward gross profit it is the least demanding of the American names.

So the group's leasing momentum is real at three of six, absent at two, and financially unproven at one. The price action across all six has been moving as one — which is what a rate shock looks like, not a leasing cycle.

The setup

Where it stands — Six leased-compute developers fell together on a 19-year high in long-term Treasury yields, days after each reported separately and divergently. Would confirm — VNET converting its 862 megawatts of orders into delivered capacity at the guided 516 megawatts over twelve months. Would invalidate — GDS revenue per cabinet falling more than the guided 3% while backlog stalls below 757 megawatts. Watch next — Applied Digital's fiscal first-quarter report in October, the first period with 175 megawatts live at Polaris Forge. Valuation — VNET 9.4x trailing EV/EBITDA and GDS 14.4x, against Applied Digital at 64.0x trailing and 44.8x forward gross profit.
