The U.S. Food and Drug Administration on Monday cleared Apple‘s new sleep apnea detection feature for use, which means it will come to the Apple Watch Series 9, Series 10 and Ultra 2 later this month.
Sleep apnea is a sleep disorder that causes a person’s breathing to repeatedly stop and start throughout the night. The condition affects more than 30 million people in the U.S., but only around 6 million are diagnosed, according to the American Medical Association. If it goes untreated, sleep apnea can cause fatigue and lead to more serious health issues like heart problems, hypertension and Type 2 diabetes.
“We are so excited about the incredible impact this feature can make for the millions of people living with undiagnosed sleep apnea,” Dr. Sumbul Desai, vice president of health at Apple, said in the feature’s launch video.
Apple’s sleep apnea detection feature marks the company’s latest attempt to position its wearables as a cheaper, simpler alternative to many existing health-care tests and devices. And the sleep disorder market could prove to be lucrative.
To get evaluated for sleep apnea, for instance, patients typically participate in an at-home test or an in-lab test where they’re monitored overnight. Prices vary depending on insurance coverage, but the average in-lab test costs $3,000, according to a 2022 study in the Journal of Primary Care & Community Health.
At-home tests are often less expensive, but they can still cost hundreds of dollars. The at-home sleep apnea test from Sleep Doctor costs $189, for example. Apple’s newest watch, the Series 10, starts at $399.
Apple’s sleep apnea detection feature is “potentially a game changer” for patients who have been reluctant to seek out testing, said Dr. David Kuhlmann, a physician who has treated sleep disorders for nearly two decades in Missouri. Kuhlmann also serves on the board of the American Academy of Sleep Medicine, which is a professional society for sleep medicine clinicians.
Kuhlmann said the feature could be especially helpful for patients who sleep alone, and he thinks a lot of people will be surprised to find out they’re showing signs of sleep apnea.
Even so, Kuhlmann said users should approach Apple’s sleep apnea data with some caution, as readings could be erroneous. He said it is unlikely that insurance companies will begin paying for sleep apnea therapies like CPAP machines based on Apple Watch data alone, which is why it is important for patients to follow up with their health-care providers to get an official diagnosis.
“People do need to be diagnosed in order to be treated,” Kuhlmann told CNBC in an interview.
Kuhlmann said the feature will likely cause an increase in visits to health-care providers, which could ultimately reduce costs for the U.S. health-care system overall. Ideally, if patients catch sleep apnea earlier, they can avoid paying for treatments for more serious conditions down the line.
“By finding out that they have these underlying sleep disorders and getting them treated, it could potentially actually help save expenses and help improve quality of life.”
How it works

Apple Inc.
Apple’s sleep apnea detection feature works by analyzing a new metric that the company calls “breathing disturbances.” The Apple Watch identifies breathing disturbances by using an accelerometer to measure movements at the wrist that indicate disruptions to normal breathing patterns.
Users can view their nightly metrics in the Health app, where they’ll be classified as either “elevated” or “not elevated,” i.e., normal. Apple will analyze this breathing disturbance data once a month and notify people if they show “consistent signs” of severe or moderate sleep apnea. Users can view their data over a one-month, six-month or one-year period.
The Apple Watch Series 10 supports an 18-hour battery life, so people who are interested in using this feature will likely need to charge their device during the day.
Apple can also generate a report that users can bring to their doctors to discuss next steps. The report includes three months’ worth of breathing disturbance data as well as some additional information, the company said. Users can access educational materials within the Health app as well.
Apple said that the notification algorithm was developed with “an extensive data set of clinical-grade sleep apnea tests,” and that the feature was validated in a clinical study.
“Now I’m jonesing to get an Apple [Watch] so I can try it out on myself,” Kuhlmann said.

Amazon shipped another batch of internet-beaming satellites into orbit on Monday atop a SpaceX Falcon 9 rocket, after four previous launch attempts were interrupted by weather issues.
Monday’s launch is the fourth Kuiper mission, and Amazon now has 102 satellites in orbit.
The Falcon 9 rocket lifted off from Cape Canaveral, Florida, at 8:35 a.m. ET. Roughly an hour after launch, SpaceX confirmed all 24 of Amazon’s Kuiper satellites were successfully deployed.
The mission was originally scheduled for last Thursday, but SpaceX was forced to scrub the launch, along with three more attempts over the past few days due to rainfall.
For the second time, Amazon turned to Elon Musk‘s SpaceX, its chief competitor in the low-earth orbit satellite market, for help building out its constellation.
SpaceX’s Starlink is currently the dominant provider of low-earth orbit satellite internet, with a constellation of roughly 8,000 satellites and about 5 million customers worldwide.
Amazon is racing to get more of its Kuiper satellites into space to meet a deadline set by the Federal Communications Commission.
The FCC requires that Amazon have about 1,600 satellites in orbit by the end of July 2026, with the full 3,236-satellite constellation launched by July 2029.
Amazon has booked up to 83 launches, including three rides with SpaceX.
While the company is still in the early stages of building out its constellation, Amazon has already inked deals with governments as it hopes to begin commercial service later this year.

Michael Moritz, Sequoia Capital

Renowned venture capitalist Mike Moritz called on Intel to stand by CEO Lip-Bu Tan after President Donald Trump demanded his resignation last week.
“Trump’s assault has no modern precedent,” Moritz wrote, calling the attack a “vindictive political sideshow.”
Moritz, who spent decades at Sequoia Capital and has known Tan for nearly four decades, highlighted the CEO’s previous turnaround of Cadence Design Systems. Moritz said there is “no one better equipped to transform Intel’s fortunes.”
“Now the Intel board must decide whether to march to the beat of so many other corporate leaders and capitulate to the president’s artless bullying or to set an example for other companies and display some backbone,” he wrote in a piece published in the Financial Times Sunday. “Early signs of defiance are encouraging.”
Tan is set to visit the White House on Monday to assuage concerns about his background and discuss ways that Intel can work with the U.S. government.
Intel shares were up nearly 5% Monday. The Wall Street Journal was first to report Tan’s White House visit.
In a post to Truth Social last week, Trump called for Tan’s resignation and said the 65-year-old was “highly CONFLICTED.” Sen. Tom Cotton, R-Ark. has also raised questions over Tan’s ties to Chinese companies and the potential national security risks.
Tan later addressed the “misinformation” in a letter to employees, saying that he has “always operated within the highest legal and ethical standards.”
Moritz joined Sequoia Capital in 1986 and stepped down in 2023. During his tenure, he made successful early bets on the likes of Google and PayPal.

C3 AI stock falls 20% as CEO Siebel calls preliminary sales numbers ‘completely unacceptable’

Shares of the enterprise artificial intelligence company C3 AI tumbled more than 20% Monday after it announced preliminary financial results and a restructuring of its global sales and services organization.
C3 AI said Friday that it expects to report revenue between $70.2 million and $70.4 million for its fiscal first quarter 2026, though those figures are unaudited, preliminary estimates. The company reported $87.2 million in revenue during the same period a year earlier.
Thomas Siebel, C3 AI’s CEO, said in a statement that sales results during the quarter were “completely unacceptable.” He attributed the performance to the “disruptive effect” of the reorganization, as well as his ongoing health issues.
The company expects to report a GAAP loss from operations for the quarter between $124.7 million and $124.9 million, a much wider loss than a year ago, when C3 AI had a loss of $72.59 million.
“Unfortunately, dealing with these health issues prevented me from participating in the sales process as actively as I have in the past,” Siebel said in a statement. “With the benefit of hindsight, it is now apparent that my active participation in the sales process may have had a greater impact than I previously thought.”
Siebel announced in July that he was diagnosed with an autoimmune disease earlier this year, resulting in “significant visual impairment.” C3 AI’s board and Siebel have kicked off a search for the company’s next chief executive.
C3 AI said its sales and services restructuring is complete, and Siebel said his health has “improved dramatically” except for his vision impairment. He said he is feeling strong and fully engaged, and will work to quickly identify “excellent” CEO candidates.
“I am confident the company is positioned to accelerate going forward,” Siebel said.
The company is scheduled to hold a conference call for first quarter results on Sept. 3 at 5 p.m. ET.
