Kingsoft Cloud has quietly turned its Chinese cloud business into an AI compute toll road, and the second quarter of 2026 proved the model works on the top line. The investment case now hinges on whether the margin recovery keeps pace with the depreciation bill that the buildout keeps adding, and whether the equity can convert a growth inflection into a durable earnings inflection before the capital cycle turns against it.
The quarter is the story. AI cloud gross billings, the total value of AI workloads customers spend on the platform before revenue recognition timing, grew 82 percent year-over-year. AI billings accounted for 56 percent of public cloud revenue. Public cloud revenue itself rose 45 percent to RMB2,357.6 million. Total revenue set a record at RMB3,072.0 million, up 30.8 percent, for a company that three quarters earlier still looked like a loss-making infrastructure bet. GAAP operating margin turned positive for the first time in the company's history, even as depreciation on newly acquired and leased AI servers pushed that line to RMB963.8 million, nearly double the year-ago level. What the quarter did not show is how much of that growth is funded by capital that the company does not yet earn back from operations, and that gap is where the investment debate actually lives.
The tension sits below the operating line and on the balance sheet. The first positive GAAP operating quarter is real but razor thin. The net loss did not disappear, because interest expense ran RMB166.8 million against a far smaller interest income. Capex including leased assets hit RMB3.3 billion in the quarter alone, so the business is still spending more on metal than it collects, and the going-concern language in the annual report means management itself treats liquidity as an open question rather than a settled one.
The timing trigger is the third-quarter print and the second-half capex commentary, which management framed around continued AI investment and deepened use of the Xiaomi and Kingsoft ecosystems. If AI cloud billings hold above roughly 60 percent of public cloud revenue and gross margin stays near 15 percent, the current skepticism has legs. The sub-$3 billion ADS market cap is the price of that doubt. If billings decelerate while depreciation keeps compounding, the multiple compresses further.
