China's State-Owned Enterprises Audit Broadcom Switch Chips, Domestic Substitution Accelerates
nashnova research
China's SASAC found Broadcom switch chips power up to 90% of state-owned data centers and is now drafting informal guidance to cut procurement — making Broadcom the next US chip giant pushed toward domestic substitution, after Nvidia.
What exactly is SASAC investigating?
SASAC — the body overseeing China's state-owned enterprises — surveyed how widely Broadcom switch chips (the core component that lets thousands of AI accelerators talk to each other inside a data center) are used across state-controlled facilities.
The finding: Broadcom's penetration may reach 90%. This means → with Nvidia already banned from state data centers, Broadcom is the last major US supplier embedded in China's national AI buildout.
The preliminary results may prompt SASAC to issue "informal guidance" directing state data centers to cut Broadcom purchases. In plain terms = "informal" in China's policy context carries almost the same force as a formal order.
What is the antitrust angle?
SASAC is also examining Broadcom's sales practices — specifically whether it leverages market dominance to bundle products or lock buyers into commitments of tens of thousands of chips.
This means → bundling squeezes out domestic preferred vendors like H3C and Ruijie Networks, limiting their room to source from Huawei and other alternative suppliers. H3C and Ruijie sit on public-sector IT procurement lists worth billions of dollars annually.
The playbook mirrors last year's ruling that Nvidia violated antitrust law in its acquisition of Mellanox — itself a networking company. Investigate sales conduct first, then push policy-driven substitution.
Who is exempt? Where are the policy boundaries?
Two important limits: private operators are not covered. ByteDance, Alibaba, and other companies doing the bulk of China's frontier model training are unaffected.
Existing equipment will not be forcibly removed. The policy targets the replacement cycle, not a rip-and-replace. In plain terms = nobody is pulling Broadcom chips out today — they switch to domestic chips next time they upgrade.
A rack-manufacturer sales representative described the policy as "part of a broader push to nationalize the supply chain." This reflects Beijing's step-by-step effort to bring every layer of AI infrastructure — from accelerators to network chips — under domestic control.
How big is Broadcom's financial exposure?
About 17% of Broadcom's FY2025 revenue — roughly $10.9 billion out of $63.9 billion — came from shipments to China (including Hong Kong), down from 20% the prior year.
But the headline number overstates actual Chinese end-demand. A significant share is "ship-to" revenue — chips sent to contract manufacturers in China that assemble equipment for non-Chinese customers. In plain terms = the chips land in China, but the finished products may ship worldwide. Broadcom's real China end-demand is smaller than $10.9 billion.
On the day the news broke, Broadcom's stock rose only about 0.5%. This means → the market sees limited near-term profit impact — after all, the policy covers only state-owned enterprises, not private cloud operators.
How large is the domestic-replacement market?
Goldman Sachs data: China's domestic AI chip market is growing at a 69% compound annual rate toward 2030.
Chinese semiconductor capex is forecast to rise 13–15% annually from 2026 through 2028, driven mainly by memory and advanced-node capacity.
SMIC posted 20% quarter-on-quarter revenue growth in Q2 2026 — the fastest among the world's top ten foundries — with utilization expected to stay above 95% in 2H 2026. This reflects that domestic substitution is no longer just a policy slogan: capital and capacity are already following through.
What to watch next?
The switch-chip market is becoming the next major battleground in China's push to localize AI infrastructure.
Whether Broadcom can hold onto private cloud operators — ByteDance, Alibaba, and peers — is the key validation point for its China business trajectory.
In plain terms = losing the state-enterprise market may already be a foregone conclusion. What truly decides Broadcom's China fate is whether private giants "voluntarily" follow the domestic-substitution trend.
