AI cloud gross billings reached RMB 1.0 billion in Q1 2026, up 90.1% year over year.
AI crossed 50.1% of public cloud revenue for the first time in Q1 2026.
Xiaomi and Kingsoft ecosystem revenue was RMB 838 million, or 31.0% of total revenue, in Q1 2026.
Adjusted gross margin fell to 13% in Q1 2026 as server costs and upfront customer costs rose.
Management now points to RMB 15-20 billion of 2026 CapEx, with supply chain capacity as a key limit.

01 Running thesis

AI demand, hard math

Kingsoft Cloud is trying to become an AI cloud company, not a plain cloud and CDN seller. The shift is working on revenue. In Q1 2026, AI cloud gross billings reached RMB 1.0 billion, up 90.1% year over year, and AI made up 50.1% of public cloud revenue.

The catch is that this growth needs expensive servers. Adjusted gross margin fell to 13% in Q1 2026. Management blamed higher server costs and upfront costs for future customer revenue, and said margins should return to normal as it passes upstream cost pressure to customers.

The biggest open question is funding. 2026 CapEx is guided at RMB 15-20 billion, and management says supply chain capacity is the main limit. The company wants customer prepayments to cover about half of CapEx, but investors still need proof that this can scale without heavy dilution or leverage.

The bull case is simple: AI inference, token services, model APIs, and agent tools keep growing, while margins recover. The bear case is just as clear: the revenue is too tied to Xiaomi and Kingsoft, the hardware bill stays too high, and chip supply blocks the buildout.

May 2026→Q1 2026 strengthened both sides of the thesis. AI cloud billings rose 90.1% year over year and crossed 50.1% of public cloud revenue, but adjusted gross margin fell to 13% and 2026 CapEx guidance rose to RMB 15-20 billion.

Apr 2026▼The 2025 Form 20-F showed full-year revenue up 22.8%, helped by AI and enterprise cloud demand. It also showed gross margin falling from 17.2% to 15.7% because of depreciation from newly acquired AI servers.

Mar 2026▲Q4 2025 showed AI billings at 49% of public cloud and two straight quarters of adjusted operating profit. Management also said 2026 CapEx would exceed RMB 10 billion, with about half targeted for customer prepayment coverage.

Nov 2025▲Q3 2025 showed AI staying at 45% of public cloud revenue and the first adjusted operating profit. Management also described using CapEx for larger ecosystem customers and leasing for riskier mid-market customers.

Aug 2025→Q2 2025 kept the AI pivot on track, with AI gross billings at 45% of public cloud revenue. The update also raised the long-term risk that domestic chip supply may not meet a future surge in inference demand.

May 2025→Q1 2025 showed AI gross billings at 39% of public cloud and ecosystem revenue at 25% of total revenue. Non-GAAP operating profit still moved back to a loss, showing that the growth mix had not yet fixed margins.

Apr 2025▲The 2024 Form 20-F confirmed the move away from lower-margin CDN toward AI and enterprise cloud. It also added a capital-raising risk if KC were ever treated as a Covered Foreign Person under the U.S. Outbound Investment Rule.

02 Business model

Renting scarce AI compute

Kingsoft Cloud makes money by selling cloud capacity and services to companies and public-sector customers. Public cloud includes compute, storage, AI cloud, and CDN. Enterprise cloud includes private and hybrid cloud projects for areas such as e-government and healthcare.

The newer model is built around AI compute. Customers need large amounts of processing power to train models, run inference, call model APIs, and deploy AI agents. Kingsoft Cloud buys, leases, or helps procure the infrastructure, then charges customers for using it.

Xiaomi and Kingsoft are central to this plan. Their ecosystem revenue reached RMB 838 million in Q1 2026 and was 31.0% of total revenue. That demand gives Kingsoft Cloud a clear base of customers, but it also creates concentration risk.

To reduce the cash strain, management is using a dual-track procurement model. It tends to use CapEx for large ecosystem customers and leasing or agent-style arrangements for riskier customers. It also targets customer prepayments for about half of CapEx, which matters because AI infrastructure spending is very large.

03 Product portfolio

What KC sells

Growth engine

AI cloud compute

This is the main growth driver. AI cloud gross billings reached RMB 1.0 billion in Q1 2026 and crossed half of public cloud revenue.

Option

Model API services

These services let customers call and manage AI models through software interfaces. The goal is to capture higher-margin inference and token usage over time.

Option

Agent Engine

Agent Engine helps customers build, deploy, and manage AI agents. It was launched to address growing demand for agent-based AI tools.

Growth engine

Public cloud

Public cloud generated RMB 2.0 billion in Q1 2026, up 47.5% year over year. AI demand is now the key reason this segment is growing.

Steady

Enterprise cloud

Enterprise cloud serves public services, e-government cloud, healthcare, and similar projects. It generated RMB 710 million in Q1 2026, up 14.7% year over year.

Cash cow

CDN

KC has been reducing lower-margin standard CDN exposure. It has split the product into standard CDN and higher-margin advanced CDN for live broadcasting and dynamic acceleration.

Enterprise Cloud26%modest

The segment mix uses Q1 2026 revenue: RMB 2.0 billion from Public Cloud and RMB 710 million from Enterprise Cloud. Xiaomi and Kingsoft are not a separate segment, but they contributed 31.0% of total revenue in the quarter.

05 Risk factors

What could break

Margins do not recover

High impact · Medium odds

Adjusted gross margin fell to 13% in Q1 2026. Management says this was temporary and tied to higher server costs plus upfront costs for future customer revenue. If cost pass-throughs fail, AI revenue growth may not translate into better profit.

We watchAdjusted gross margin in the next two quarters, especially whether it moves back toward prior normal levels.

CapEx funding gap

High impact · Medium odds

Management guided 2026 CapEx at RMB 15-20 billion. It wants customer prepayments to cover about half of CapEx, but that still leaves a large financing need. If prepayments fall short, shareholders could face dilution or the balance sheet could take on more risk.

We watchCustomer prepayment levels, cash flow, new debt, and any equity issuance.

Ecosystem concentration

High impact · Medium odds

Xiaomi and Kingsoft ecosystem revenue was RMB 838 million in Q1 2026, equal to 31.0% of total revenue. That demand helps growth, but it also means KC is heavily tied to related parties. A slowdown or contract change inside that ecosystem would hit the story fast.

We watchXiaomi and Kingsoft ecosystem revenue as a percent of total revenue.

Chip and server supply squeeze

High impact · High odds

AI cloud needs advanced servers, and management has cited supply chain capacity as the main limit on 2026 CapEx. U.S. chip export restrictions and domestic chip limits add risk. Management has also warned that a future surge in inference demand could outstrip domestic chip supply.

We watchManagement comments on server availability, chip substitution, and delays in AI capacity delivery.

AI demand stays low-margin

Medium impact · Medium odds

The company is betting that token services, model APIs, and MaaS can raise margins. But much of the current growth still needs heavy hardware spending. If customers mainly buy raw compute at low spreads, the business may stay capital-heavy.

We watchMix of token, model API, MaaS, and agent revenue versus raw AI compute billings.
