China Weighs Letting Alibaba Buy Nvidia Chips; Cambricon Falls 5.7%

On Sunday a report said Beijing had asked its companies a question about an Nvidia chip.

On Monday morning, chip stocks fell in Shanghai.

The question has no answer yet. It already has a price.

What Beijing Actually Did

According to The Information's report on Sept. 27, China's Ministry of Industry and Information Technology put a question to several companies, including Alibaba and ByteDance. How many RTX Pro 5500s, which Nvidia released in September, do you plan to buy, and what will you use them for?

The report said the inquiry signaled an intent to eventually approve the sales. ByteDance is reportedly weighing an order of about 1 million units.

This is not an approval. It is a survey.

Reuters said it could not independently verify the report. The ministry, Alibaba and ByteDance did not comment.

Why This Chip

The RTX Pro 5500 is not a data center accelerator. It is a rack-mounted workstation card on the Blackwell architecture, with 84 GB of GDDR7 memory.

The distinction matters. What the U.S. has blocked from China since October 2022 is data center accelerators. Some industry executives believe the 5500 falls outside those controls; that has not been confirmed.

For Nvidia, the picture is this. Its finance chief was blunt on the August earnings call.

"There is no China data center compute revenue in our forward outlook."

So any sale in China would be revenue on top of guidance.

The Second Headline, From Washington

The news that hit optical stocks over the same weekend came from elsewhere.

On Sept. 25, Senators Dave McCormick, Ruben Gallego, John Cornyn and John Fetterman introduced a bill. It would bar federal purchases of optical transceivers from Zhongji Innolight and Eoptolink for U.S. national security systems. Transceivers are the hardware that turns light in fiber cable into data.

The bill's scope is narrow. It covers only purchases for the federal government's national security systems, and the ban starts only after a five-year transition. It is not law.

Billy Leung of Global X put it briefly: "The direct earnings impact is limited."

Neither Headline Is a Decision

In one, a ministry asked a question. In the other, four senators introduced a bill.

The market priced both as decisions.

The reason lies in what investors pay for in domestic chipmakers. A company like Cambricon is valued less on today's profit than on future guaranteed demand. What guarantees that demand is Beijing keeping Nvidia out.

For Nvidia, that is a large addition but it does not change the whole picture on its own. For a Chinese chipmaker, the lost order changes category: projected demand becomes demand going to a rival.

That is where the asymmetry comes from. The same headline lands with different weight on each side.

What Fell on Monday

According to closing figures compiled by Investing.com, the losses split into two groups. Chipmakers took the hit from the Nvidia report. Optical firms took the hit from the Senate bill.

The optical selloff spread beyond the two companies the bill names. Hengtong Optic-Electric and Fiberhome fell 10%, and Accelink 9.9%.

Nvidia shares closed at $225.07 on Sept. 25. Monday's session will be the first U.S. test of the report.

The chart is only a frame; it shows the price before Monday's U.S. open, not the report's effect.

The Part That Does Not Fit

Pinning the whole decline on two headlines would go beyond what the sources say.

The Hang Seng rose 0.7% the same day. Brent approached $107, and global bond yields averaged above 4% for the first time since 2007. Marvin Chen of Bloomberg Intelligence said investors were reluctant to enter the market ahead of the National Day holiday.

There is also a precedent. In January 2026, Beijing encouraged its companies to prepare H200 orders, and the U.S. granted licenses to seven Chinese firms. Beijing then discouraged the purchases; as of May, not a single H200 had reportedly been delivered to China.

Between a question and a delivery sit three separate approvals: Beijing's, Washington's and Chinese customs'.

What Is Left

Export controls were not discussed at the summit; U.S. Trade Representative Jamieson Greer said the topic was taken off the table. We covered the summit's tariff side earlier.

Leung said tech restrictions are running on a separate track from diplomacy. Monday showed it from both directions. Beijing is opening one door while Washington tries to close another.

This story draws on reports of The Information's Sept. 27 article by Reuters, Investing.com and Seoul Economic Daily; Senator McCormick's Sept. 25 press release; Nvidia's August earnings disclosures (our second-quarter analysis); and Caixin's exchange-rate data. ByteDance's order size and the China selling price appear only in secondary reports; the Chinese government and the companies involved have not confirmed the report.
