AI demand is remaking VNET
- Wholesale data centers passed retail revenue for the first time in Q1 2026.
- Capacity in service reached 907 MW, and wholesale utilization improved to 75.7%.
- VNET secured 519 MW of new orders year-to-date 2026, with delivery planned through 2028.
- CATL affiliates agreed to buy up to about 38.1% of VNET shares from Shandong Hi-Speed affiliates.
- The main catch is funding: 2026 CapEx guidance is still RMB 10 billion to RMB 12 billion.
AI orders meet a funding test
VNET is becoming more of an AI data center company. In Q1 2026, wholesale IDC revenue passed retail revenue for the first time. Wholesale capacity in service reached 907 MW, and utilization rose to 75.7%, which means more of the built capacity is being used by customers.
The bull case is simple: AI customers need huge amounts of power, space, cooling, and fast delivery. VNET says it has secured 519 MW of orders year-to-date 2026, with delivery planned from 2026 through 2028. CATL's planned investment also matters because CATL may help with energy storage, power systems, and supply chain support for large AI data centers.
The bear case is also simple: this buildout costs a lot. Management guides to RMB 10 billion to RMB 12 billion of CapEx in 2026, after RMB 8.24 billion in 2025. VNET has made real progress by listing two private REIT projects in March 2026 with a total offer size of about RMB 6.36 billion, but the company still needs capital markets, partners, and customer move-ins to work on time.
The key question is not whether AI demand exists. The question is whether VNET can turn signed demand into used capacity and cash flow before debt and construction needs squeeze the company.
Renting power, space, and uptime
VNET makes money by selling data center capacity and related computing services. Customers pay for space, power, cooling, network links, and uptime. The company says about 90% of revenue is recurring, and core IDC churn has stayed below 1%, which gives the business better visibility than many project-based tech companies.
There are two main IDC models. Wholesale customers take large blocks of capacity, often measured in megawatts. Retail customers rent smaller amounts of capacity, often measured by cabinets. Retail is steadier, while wholesale is now the faster growth engine because AI workloads need large sites.
The company is trying to fund growth without owning every asset forever. It uses joint ventures, pre-REIT funds, private REITs, and public REIT structures to recycle capital. In plain English, VNET can sell or finance mature data center assets, then use the cash to build more capacity.
The weak spot is timing. If new capacity is built before customers move in, cash leaves before cash comes back. That is why the low financial health profile matters even while the growth story has improved.
From cabinets to AI campuses
Wholesale IDC
This is the large-customer data center business. It reached RMB 1.06 billion of revenue in Q1 2026 and is now VNET's biggest segment.
Retail IDC
Retail IDC serves customers that need cabinets rather than whole megawatts. It had 51,770 cabinets in service and 64.1% utilization in Q1 2026.
AI data center solutions
VNET is upgrading sites for AI workloads and moving from simple capacity delivery toward a broader AIDC platform. The Hyperscale 2.0 framework uses modular construction to cut build cycles by one-third.
Hybrid IT services
Hybrid IT bundles retail IDC rental with extra GPUs and software support. This gives VNET a way to serve AI inference demand from smaller or mixed-use customers.
Cloud and VPN services
These non-IDC services add revenue around the core data center base. Growth is slower, with non-IDC revenue up 0.3% year over year in Q1 2026.
Wholesale takes the lead
The segment mix uses Q1 2026 net revenue from the earnings call: RMB 1.06 billion wholesale, RMB 1.02 billion retail, and RMB 606.6 million non-IDC. Wholesale capacity is concentrated in the Greater Beijing Area and Yangtze River Delta, with more resources being secured in Ulanqab and other compute hubs.
What could break
CapEx outruns funding
High impact · High oddsVNET expects RMB 10 billion to RMB 12 billion of CapEx in 2026. That is a heavy bill for a company already carrying a weak financial health profile. REIT listings help, but they need to keep working.
Signed orders move in too slowly
High impact · Medium oddsVNET has big orders, including 519 MW year-to-date 2026, but orders only pay off when customers move in and use capacity. At year-end 2025, wholesale commitment was 95.3% while utilization was 70.1%, showing that signed demand can lead actual use by a wide gap.
Power and land constraints delay sites
Medium impact · Medium oddsAI data centers need power, cooling, land, and permits. VNET is acquiring large resources in Ulanqab, the Yangtze River Delta, and East Data West Compute hubs, but resource control does not remove execution risk.
Chip controls hit customer demand
Medium impact · Medium oddsManagement said earlier disruption from the U.S. H20 chip embargo had stabilized, and later noted NVIDIA had regained shipping permission for new chipsets to China. That risk has eased, but export controls can change fast.
Competition weakens pricing
Medium impact · Medium oddsChina's data center market has strong local competitors. If too much capacity is built in the same regions, customers may demand lower prices or better terms. Retail utilization near the mid-60% range also leaves room for pricing pressure.
In one breath
What does VNET Group do?
VNET runs data centers and related cloud, VPN, and computing services in China. Its biggest growth area is wholesale data center capacity for large AI and internet customers.
Why is AI important to VNET?
AI workloads need large amounts of power, cooling, and reliable data center space. VNET is using wholesale campuses and its Hyperscale 2.0 framework to deliver that capacity faster.
Why is VNET financially risky?
Building AI data centers requires very high upfront spending. VNET guides to RMB 10 billion to RMB 12 billion of CapEx in 2026, so it depends on customer move-ins and capital recycling to keep the balance sheet from getting stretched.
What is CATL's role in the VNET story?
CATL affiliates agreed to acquire up to about 38.1% of VNET shares from Shandong Hi-Speed affiliates. The strategic idea is to help VNET with energy storage, power management, technology, and supply chain support for AI data centers.
