Elon Musk’s startup Neuralink streamed a live video on Wednesday that showed a patient using the company’s brain implant to move a mouse and play chess on a computer.
Noland Arbaugh, 29, is the first human patient to ever get implanted with Neuralink’s device. The company is developing a brain-computer interface, or a BCI, that aims to help patients with severe paralysis control external technologies using only neural signals. Neuralink’s first product is called Telepathy, Musk said in a post on his social media site X in January.
In the video Wednesday, which was streamed on X, Arbaugh said he became a quadriplegic after suffering a diving accident around eight years ago. He said the surgery to get Neuralink’s implant, which requires patients to remove a portion of their skull to insert electrodes into the brain tissue, was “super easy.” He was released from the hospital the next day, he said.
“It’s not perfect, I would say that we have run into some issues,” Arbaugh said. “I don’t want people to think that this is the end of the journey, there’s still a lot of work to be done, but it has already changed my life.”
A BCI is a system that deciphers brain signals and translates them into commands for external technologies. If the system functions properly, patients with severe degenerative diseases like ALS could eventually text or scroll through social media with their minds.
Several companies like Paradromics, Synchron, Blackrock Neurotech and Precision Neuroscience have developed BCI systems with these capabilities, and many of them have also implanted devices in human patients. Neuralink is particularly well known in the field due to the high profile of Musk, who is also the CEO of Tesla and SpaceX.
In many ways, the capabilities Neuralink demonstrated in its video Wednesday are not new. Dr. Nader Pouratian, chair of the Department of Neurological Surgery at UT Southwestern Medical Center, said researchers have been developing and studying BCI technology for years.
“There are things that we’ve been able to do for decades, like control a cursor in two dimensions, which actually, for those of us who are in the field, is extremely simple to do as soon as you can get any brain signal,” he told CNBC in an interview earlier this month.
He said there is a lot of excitement around BCIs, but admitted there is a host of practical challenges to work out, like how to interpret and analyze brain signals and make them useful. Pouratian said he thinks transparency from both academia and the broader BCI industry about advancements will be key for progress.
Neuralink began recruiting patients for its first in-human clinical trial in the fall after it received approval from the U.S. Food and Drug Administration to conduct the study in May 2023, according to a blog post. In January, Musk said the company implanted its device in a human for the first time, and that the patient, now revealed to be Arbaugh, was “recovering well,” according to a post on X.
Aside from Musk’s posts, Neuralink has shared very few details about the scope or the nature of its trial. As of Wednesday, the trial is not listed on the website clinicaltrials.gov, which is where most medical device companies share information about their research to help inform the public and other health-care professionals about their ambitions.
It is not clear how many patients are participating in Neuralink’s trial, or what the trial is trying to demonstrate. The company will have to go through several rounds of safety and efficacy testing before it can get the FDA’s final seal of approval and go to market.
Neuralink did not respond to CNBC’s request for comment.
There is reason to be hopeful about Neuralink’s technology, said Dr. Marco Baptista, chief scientific officer of the Christopher & Dana Reeve Foundation, which provides resources to people who have become paralyzed. He told CNBC in early March that BCI technology could make a meaningful impact on patients, but like all emerging devices, Neuralink’s system should be regarded with skepticism.
He said he would like to see more traditional scientific reports from Neuralink to learn more about its technology, for instance. Neuralink is listed as an author on one white paper from 2019, according to PubMed.
“I’m hopeful that this information will start to come out through these mechanisms that are needed in science, and that is through peer reviewed publications,” Baptista said. “That hasn’t happened yet. Other companies are doing it.”
China’s Pony.ai on Thursday saw its shares drop over 12%, while rival WeRide fell nearly 8% as the autonomous driving companies began trading in Hong Kong.
Pony.ai and WeRide, which are already listed in the U.S., raised 6.71 billion Hong Kong dollars (about $860 million) and HK$2.39 billion, respectively in their initial public offerings.
The companies are striving to keep pace with larger competitors such as Baidu‘s Apollo Go in China and Alphabet‘s Waymo in the U.S. amid growing interest in autonomous technologies.
Pony.ai and WeRide, both headquartered in Guangzhou, China, stated that funds would go toward scaling efforts, and the development of Level 4 autonomous driving — a measure of driving automation that does not require human monitoring or intervention under specific environments.
WeRide CEO Tony Xu Han told CNBC that proceeds from the latest fundraising would also be used to boost the company’s artificial intelligence capabilities and data center capacity.
The listings in Hong Kong come as the companies seek to expand outside of China, where they have already begun operating fully autonomous robotaxis in some cities.
The new regions include the Middle East, Europe and Asian countries such as Singapore. They have yet to receive full approvals to operate their robotaxis in most of those regions.
In the U.S., both companies are aiming for a partnership with California-based Uber to allow them to deploy their robotaxis on the firm’s ride-hailing platform after receiving regulatory approval.
However, their U.S. plans face headwinds as earlier this year the government finalized a rule effectively banning Chinese technology in connected vehicles, including self-driving systems.
“With the uncertainty in the markets around the world and the fact that there would be intense scrutiny on a Pony or WeRide trying to enter the U.S. market, a dual listing is a lot about risk mitigation,” said Tu Le, founder and managing director at Sino Auto Insights.
He added that the listings were also an acknowledgement that it’s gonna take a lot of capital and an endorsement of a market outside the U.S. for Pony.ai and WeRide to succeed.
In U.S. trading on Wednesday, shares Pony.ai closed down about 2%, while WeRide fell 5.3%.
Hong Kong IPO shift
Pony.ai and WeRide’s competing listings highlight a recent trend of Chinese companies seeking dual listings in Hong Kong, which has been a bounce-back year for the city’s IPO market.
The companies received approval from Hong Kong regulators to dual list in mid-October.
“For the HK stock exchange, clustering the listing at the same time helps to reinforce investor perception of HK as a tech-hub for Asia-focused technology companies,” Rolf Bulk, equity research analyst at New Street Research told CNBC.
In May, Chinese battery manufacturer and technology company CATL completed a secondary listing in Hong Kong, raising $5.2 billion in the world’s largest IPO so far this year.
The growing trend emerges amid geopolitical tensions and regulatory uncertainty in the U.S.
According to New Street Research’s Bulk, the Hong Kong listings for Pony.ai and WeRide will help the companies gain access to Asia-based capital and expand their presence in China and the region.
“However, it will do nothing to advance the progress of their technology stack and regulatory approvals in Western markets. If anything, gaining approval in Western markets may be more challenging with a HK secondary listing,” he added.
The listings could also help the firms keep up with competitors such as Baidu‘s Apollo Go in China and Alphabet‘s Waymo in the U.S., which currently have larger fleets.
“Pony and WeRide are right up there among the global leaders,” said Sino Auto Insights’ Le. “WeRide has diversified their service portfolio a bit more but they both see Uber and the Middle East as two viable partners in their ability to get more pilots launched outside of China.”
“Investors should pay special attention to how their technology evolves with AI and other new tools becoming more mainstream,” Le said.
Microsoft President Brad Smith speaks at a press conference at the Representation of the State of North Rhine-Westphalia about future visions for the development and application of artificial intelligence in education in NRW in Berlin on June 4, 2025.

Microsoft is giving employees a way to raise concerns about the uses of its technology after controversy emerged over the company’s work in the Middle East.
An internal portal for Microsoft’s 200,000-plus workers now includes an option to request a “Trusted Technology Review,” Brad Smith, the company’s president, wrote in a memo that was disclosed in a securities filing on Wednesday. It’s designed for bringing up misgivings about the ways Microsoft builds and uses technology, he said.
“Our standard non-retaliation policy applies, and you can raise concerns anonymously,” Smith wrote.
The move comes weeks after Microsoft stopped providing some services to an Israeli defense unit. In August, The Guardian said the Israeli Defense Forces’ Unit 8200 had built a system in Microsoft’s Azure cloud for tracking Palestinians’ phone calls as part of the country’s invasion of Gaza, leading Microsoft to investigate the newspaper’s assertions.
Employees protested the company’s work with Israel, leading to firings and resignations.
Microsoft’s business has been on a tear, with its stock reaching a record last week, as OpenAI and other companies have deepened their reliance on Azure for running artificial intelligence models. Yet there’s been internal stress due to layoffs, return-to-office mandates and controversy surrounding Microsoft’s contracts.
A media report in July also described the U.S. Defense Department’s dependence on Microsoft engineers located in China.
Microsoft, which celebrated its 50th birthday in April, now sees opportunities to boost its governance.
“We are working to strengthen our existing pre-contract review process for evaluating engagements that require additional human rights due diligence,” Smith wrote.

DoorDash reported third-quarter earnings that missed analyst expectations and said it expects to spend “several hundred million dollars” on new initiatives and development in 2026.
The stock sank 9% following the report.
Here’s how the company did compared to LSEG estimates:
Earnings: 55 cents per share vs 69 cents per share expected
Revenue: $3.45 billion vs $3.36 billion expected.
“We wish there was a way to grow a baby into an adult without investment, or to see the baby grow into an adult overnight, but we do not believe this is how life or business works,” the company wrote in its earnings release to explain the boosted spending.
DoorDash said it is developing a new global tech platform that progressed in 2025 but is expected to accelerate in 2026, noting the direct and opportunity costs in the near term. The company announced its Dot autonomous delivery robot in September.
The food delivery platform’s revenue increased 27% from a year earlier.
DoorDash posted net income of $244 million, or 55 cents per share, in Q3, up from $162 million, or 38 cents per share, a year ago.

Total orders grew 21% over the prior year to 776 million during the quarter that closed Sept. 30, just above the 770.13 million expected by FactSet.
The company expects Adjusted EBITDA for the fourth quarter in the range of $710 million to $810 million, a midpoint of $760 million. Analysts polled by FactSet expected $806.8 million for Q4.
DoorDash closed its acquisition of British food delivery company Deliveroo on Oct. 2, a deal that valued the UK company at about $3.9 billion.
The company expects a depreciation and amortization expense of $700 million for the fiscal year, exclusive of the acquisition. A stock-based compensation expense of $1.1 billion is also expected for fiscal 2025.
DoorDash expects Deliveroo to add $45 million to adjusted EBITDA in Q4 and about $200 million to adjusted EBITDA in 2026.
