China’s chip stocks rallied on Monday morning following Beijing’s announcement to bar some purchases of products from U.S. memory chipmaker Micron.
China’s Cyberspace Administration barred operators of “critical information infrastructure” in China from buying products from the U.S. chip giant following a security review conducted by the Cyberspace Administration of China.
Chinese authorities said Micron products have failed its network security review, and cited “serious potential network security issues.” The firm poses a “major security risk” to China’s critical information infrastructure supply chain and affects [its] national security,” a statement said.
Shares of Chinese chipmakers largely rose on Monday following the move: Hong Kong-listed Hua Hong Semiconductor rose as much as 3.14% on Monday, while SMIC rose 2.64%.
Other memory chip producers in mainland China such as GigaDevice Semiconductor and Ingenic semiconductor jumped 3.74% and 8.08% respectively.
In response to Beijing’s announcement, the U.S. Commerce Department’s spokesperson said, “We firmly oppose restrictions that have no basis in fact.” The department will engage with the Chinese government to “detail” its position and seek further clarity, they added.
The spokesperson added that the U.S. will engage with its key allies to address Beijing’s actions, and that such measures will cause “distortions of the memory chip market.”
This comes as the U.S. reportedly urged South Korean chipmakers not to fill the shortfalls in China if Beijing’s ban comes into effect, the Financial Times reported.
Shares of South Korean chipmakers SK Hynix and Samsung Electronics, both Micron rivals, rose on Monday morning.

OpenAI’s new artificial intelligence video app Sora has already grabbed the top spot in Apple‘s App Store as its number one free app, despite being invite-only.
Sora, which was launched on Tuesday, allows users to create short-form AI videos and share them in a feed. The app is available to iPhone users but requires an invite code to access.
Here’s how to snag a Sora app invite code:
- First, download the app from the iOS App Store. Note that Sora requires iOS 18.0 or later to be downloaded.
- Login using your OpenAI account.
- Click “Notify me when access opens.”
A screen will then appear asking for an access code.
Currently, OpenAI has said that it is prioritizing paying ChatGPT Pro users for Sora access. The app is only available in the U.S. and Canada, but is expected to roll out to additional countries soon, the company said.
If you do not know someone who can provide an access code, several people are sharing invite codes on the official OpenAI Discord server, as well as on X and Reddit threads.
Once you input your access, you will be able to start generating AI videos using text or images. Users are also able to cameo as characters in their videos as well as “remix” other posts.
The app is powered by the new Sora 2.0 model, an updated version of the original Sora model from last year. The video generation model is “physically accurate, realistic, and more controllable” than prior systems, the company said in a blog post.

OpenAI now has two of the top three free apps in Apple’s App Store, and its new video generation app Sora has snagged the coveted No. 1 spot.
The artificial intelligence startup launched Sora on Tuesday, and it allows users to generate short-form AI videos, remix videos created by other users and post them to a shared feed. Sora is only available on iOS devices and is invite-based, which means users need a code to access it.
Despite these restrictions, Sora has secured the top spot in the App Store, ahead of Google‘s Gemini and OpenAI’s generative chatbot ChatGPT.
“It’s been epic to see what the collective creativity of humanity is capable of so far,” Bill Peebles, head of Sora at OpenAI, wrote in a post on X on Friday. “Team is iterating fast and listening to feedback.”
Sora is powered by OpenAI’s latest video and audio generation model called Sora 2. OpenAI said the model is capable of creating scenes and sounds with “a high degree of realism,” according to a blog post. The startup’s first video and audio generation model, Sora, was announced in February 2024.
OpenAI said it has taken steps to address potential safety concerns around the Sora app, including giving users explicit control over how their likeness is used on the platform. But some of the initial videos posted to the app, including one that depicts OpenAI CEO Sam Altman shoplifting, have sparked debates about its utility, potential for harm and legality.
“It is easy to imagine the degenerate case of AI video generation that ends up with us all being sucked into an RL-optimized slop feed,” Altman wrote in a post on X on Tuesday. “The team has put great care and thought into trying to figure out how to make a delightful product that doesn’t fall into that trap, and has come up with a number of promising ideas.”
