Chinese chip firms hit record revenue amid AI boom and U.S. curbs

Chinese semiconductor companies have reported record revenue levels in 2025, driven by surging domestic demand for AI hardware and the secondary effects of tightened U.S. export controls that have encouraged customers to turn to local suppliers.

Notably, Beijing-listed AI chip designer Cambricon reported a dramatic year‑on‑year rise in sales and returned to profitability in the first half of 2025, a development that underlined how domestic accelerators have moved from niche projects to commercial scale. At the same time, startups such as Moore Threads and MetaX filed prospectuses for large initial public offerings, explicitly citing U.S. export restrictions as both a risk and an opportunity that could speed domestic substitution.

Market reaction reflected the revenue surprise: shares of leading domestic AI‑chip names and technology‑focused indices outperformed broader benchmarks in short bursts as investors re‑weighted portfolios toward companies seen as beneficiaries of on‑shore demand. Higher order books from cloud providers and increased prepayments for accelerator cards pointed to near‑term revenue visibility for several suppliers.

The backdrop is a tightening of U.S. export policy on advanced AI accelerators, which has at times restricted shipments of tailored products to China and prompted firms like NVIDIA to take material charges related to affected inventory and contracts. Those measures have reshaped procurement strategies among Chinese hyperscalers and telco operators, who are increasingly signing up for domestically produced solutions while Beijing amplifies industrial support for semiconductor self‑reliance.

Looking ahead, analysts expect a bifurcated market: aggressive capacity expansion and M&A in China to scale local champions, alongside potential margin pressure as suppliers invest heavily in fabs and packaging to meet AI demand. For investors, the key variables will be technology roadmaps, access to critical manufacturing equipment, and the durability of policy‑driven demand — factors that will determine which domestic players can convert rapid revenue growth into sustainable profits.
