Nvidia's China Share Falls to 34% as Huawei Gains, IDC Says

This update is a roundup of same-day reporting from the linked sources below, with editorial context from the CPJ Stock Desk.

Nvidia’s share of China’s data-centre AI chip market fell to 34% in the first half of 2026, according to an IDC report seen by Reuters. Separately, SpaceX faces new scrutiny and lock-up questions, while Oracle and Palantir drew investor attention.

Key points

Nvidia’s China data-centre AI chip share was 34% in H1 2026 as export controls limited supply and domestic rivals led by Huawei gained ground, per IDC via Reuters.
DeepSeek and Huawei are working together on software and hardware built around Huawei’s Ascend chips, which could reduce reliance on Nvidia’s CUDA ecosystem.
SpaceX has agreed to testify to the New York City Council on AI safety after receiving a subpoena.
Oracle closed up 1.1% near $138.90 on October 13 amid elevated options activity.
One analysis argues Palantir would need a sharp rise in profits, not only a larger AI market, to justify $300.

The IDC figure is the most concrete data point of the day. Nvidia held 34% of China’s data-centre AI chip market in the first half of 2026. The report attributes the decline to two factors: US export controls that restricted supplies of Nvidia products, and domestic competitors, led by Huawei, gaining ground. The summary does not give prior-period shares or Huawei’s exact number, so the size of the shift cannot be measured from the material provided.

A short video explainer covers the software angle. It says DeepSeek and Huawei are collaborating on AI software and hardware around Ascend chips, potentially lessening dependence on CUDA. It also says Nvidia remains central to the global AI industry and that China still faces hurdles in advanced chip manufacturing and production capacity. That is commentary rather than hard data, but it frames the debate: share loss in China is real, while Huawei’s ability to scale output is still an open question.

For investors, the practical takeaway is that China exposure is shrinking for Nvidia because of policy and local competition. How much that matters depends on demand elsewhere, which today’s sources do not address.

What is going on with SpaceX?

SpaceX appears across several items. CNBC reports the company agreed to testify before the New York City Council in an investigation into AI safety risks, after receiving a subpoena. No details on the testimony date or content were provided in the summary.

On supply of shares, FinanceFeeds says the lock-up releases pre-IPO shares in nine steps. Four day-count windows have passed, and the largest tranche depends on an unannounced Q3 date. Until that date is set, the timing of the biggest potential supply overhang is uncertain.

A RealClearMarkets opinion piece argues the company’s IPO obscured a quieter breakthrough that could transform satellite communications. The summary offers no specifics, so treat it as a viewpoint.

What about Oracle and Palantir?

Oracle rose $1.51, or 1.1%, to close near $138.90 on October 13, according to GuruFocus, which also cites rising implied volatility and options data from Cboe. Higher implied volatility signals traders expect larger price swings, not a direction on its own.

On Palantir, GuruFocus says reaching $300 by year-end would take a sharp increase in profits rather than just a bigger AI market. The framing is a scenario analysis, not a forecast.
