Dexcom on Tuesday announced that its new over-the-counter continuous glucose monitor called Stelo has been cleared for use by the U.S. Food and Drug Administration, and it will be available for purchase online this summer.
Continuous glucose monitors, or CGMs, are small sensors that poke through the skin to track glucose levels in real time. They are primarily used by patients with diabetes since the information is wirelessly sent to a smartphone, which can help alert users, their families and their doctors to emergencies.
Dexcom’s new CGM is designed for patients with Type 2 diabetes who do not use insulin, and it is the first glucose biosensor that does not require a prescription, according to a release Tuesday. This means Stelo will be accessible to people who do not have insurance coverage for CGMs, Dexcom said.
There are more than 25 million Type 2 diabetes patients in the U.S. that do not use insulin, according to the release from Dexcom. While Dexcom’s existing G7 CGM system is available to this population, patients have to get a prescription for it. As a result, it’s not easily accessible to all Type 2 patients.
“CGMs can be a powerful tool to help monitor blood glucose. Today’s clearance expands access to these devices by allowing individuals to purchase a CGM without the involvement of a health care provider,” Dr. Jeff Shuren, director of the FDA’s Center for Devices and Radiological Health, said in a release.
Shares of Dexcom popped more than 2% in extended trading Tuesday.
Dexcom shared Stelo’s name, as well as the fact that the device had been submitted to the FDA for review in February. The sensor will be worn on the upper arm, and it lasts for up to 15 days before it needs to be replaced, according to Dexcom’s website.
Jake Leach, chief operating officer at Dexcom, told CNBC in February that Stelo will have its own unique platform and branding. The platform will be tailored for the needs of these Type 2 patients, he said, which means it will not include many of the alerts and notifications meant for diabetes patients at risk of experiencing more serious emergencies.
“It’s designed to be a simpler experience,” Leach said in an interview. “There’s a lot of people who could benefit.”
Leach said as Dexcom is able to demonstrate the benefits of Stelo, the company believes insurance companies will eventually pay for it. He said Dexcom decided to get the product out to the market at an “approachable” cash pay price first to help get it into users’ hands quickly.
“I think it’s important for people to have that insight — it’s like a mirror into their body,” he said. “It’s very personal.”

Amazon plans to close all of its Fresh supermarkets in the U.K., in the latest recalibration of its grocery strategy.
The company said in a Tuesday blog that it’s preparing to close all 19 of its Fresh U.K. stores, “following a thorough evaluation of business operations and the very substantial growth opportunities in online delivery.” Five of the Fresh locations are expected to be converted into Whole Foods stores, Amazon said.
Amazon opened its first Fresh location outside the U.S. in London in 2021, about a year after it debuted the store concept in the Woodland Hills neighborhood of Los Angeles. Fresh stores offer cheaper prices and more mass-market items compared to Whole Foods, the upscale supermarket chain Amazon acquired for $13.7 billion in 2017. Many of the stores also feature Amazon’s cashierless “Just Walk Out” technology.
The Fresh store pullback in the U.K. comes as Amazon has continued to adjust its grocery ambitions. The company has slowed expansion of its Fresh grocery chain and Go cashierless stores in the U.S. It still maintains 500 Whole Foods locations and has opened mini “daily shop” Whole Foods stores in New York City.

At the same time, Amazon CEO Andy Jassy and other company executives have touted the success of sales of “everyday essentials” within its online grocery business, which refers to items like canned goods, paper towels, dish soap and snacks.
Jassy told investors at the company’s annual shareholder meeting in May that he remains “bullish” on grocery, calling it a “significant business” for Amazon.
The company on Tuesday also said that it plans to offer same-day delivery of groceries, including perishable items, in the U.K. beginning next year.

BYD has a backup plan if it gets cut off from the Nvidia chips it currently uses in its cars, a top executive at the Chinese electric carmaker told CNBC on Tuesday.
Stella Li, executive vice president at BYD, said the company had not received any directive from the Chinese government to stop using Nvidia chips — but if it did, it has a plan B.
“Everybody has a backup. BYD has [a] backup,” Li told CNBC’s Dan Murphy.
Li declined to expand on what the plan is, but she pointed to the Covid-19 pandemic during which there was a global shortage of semiconductors which badly affected the auto sector. BYD had “no issue” at the time because it developed a lot of its technology in-house, he said, so it was able to source alternatives quickly.
Indeed, BYD has sought to have control over large parts of its supply chain, from manufacturing its own cars to developing its own batteries.
“We have a lot of strong … even deeper technology in-house, so we always have backup,” Li said.
Nvidia, whose chips underpin much of the world’s artificial intelligence development, has been caught in the crossfire amid U.S.-China tensions. The company’s H20 AI chip — designed specifically to comply with U.S. export restrictions to China — was first banned, then permitted to be sold in China this year after a revenue-share deal between Washington and Nvidia.
Nvidia designs an entirely different set of semiconductors for cars, however.
One of Nvidia’s systems, Nvidia Drive AGX Orin, is designed to enable cars to carry out some driving tasks autonomously. BYD is a customer of this product.
There is no indication so far that the Chinese government is looking to ban this Nvidia system.
Li said BYD had not been told to stop using any Nvidia products, adding it was unlikely that Beijing would ban the U.S. firm’s auto chips.
“I don’t think any country will do that, because this automatic will kill Nvidia,” Li said. “So Nvidia now is the highest market value company, so if they lose the big market from China … nobody wants to see this.”
Amazon and the Federal Trade Commission are squaring off in a long-awaited trial over whether the company duped users into paying for Prime memberships.
The lawsuit, filed by the FTC in June 2023 under the Biden administration, alleges that Amazon deceived tens of millions of customers into signing up for its Prime subscription program and sabotaged their attempts to cancel it. Amazon has denied any wrongdoing.
The trial is being held in a federal court in Seattle, Amazon’s backyard. Jury selection began Monday and opening arguments are slated for Tuesday, with the trial expected to last about a month.
Launched in 2005, Amazon’s Prime program has grown to become one of the most popular subscription services in the world, with more than 200 million members globally, and it has generated billions of dollars for the company. Membership costs $139 a year and includes perks like free shipping and access to streaming content. Data has shown that Prime members spend more and shop more often than non-Prime members.
Amazon founder and executive chairman Jeff Bezos famously said the company wanted Prime “to be such a good value, you’d be irresponsible not to be a member.”
Regulators argue that Amazon broke competition and consumer protection laws by tricking customers into subscribing to Prime. They pointed to examples like a button on its site that instructed users to complete their transaction and did not clearly state they were also agreeing to join Prime for a recurring subscription.
“Millions of consumers accidentally enrolled in Prime without knowledge or consent, but Amazon refused to fix this known problem, described internally by employees as an ‘unspoken cancer’ because clarity adjustments would lead to a drop in subscribers,” the agency wrote in a court filing last week.
The FTC says that the cancellation process is equally confusing, requiring users to navigate four webpages and choose from 15 options — a “labyrinthian mechanism” that the company referred to internally as “Iliad,” referencing Homer’s epic poem about the Trojan War.
Amazon has argued that the Prime sign up and cancellation processes are “clear and simple,” adding that the company has “always been transparent about Prime’s terms.”
“Occasional customer frustrations and mistakes are inevitable — especially for a program as popular as Amazon Prime,” the company wrote in a recent court filing. “Evidence that a small percentage of customers misunderstood Prime enrollment or cancellation does not prove that Amazon violated the law.”
A crackdown on ‘dark patterns’
The FTC notched an early win in the case last week when U.S. District Court Judge John Chun ruled Amazon and two senior executives violated the Restore Online Shoppers’ Confidence Act by gathering Prime members’ billing information before disclosing the terms of the service.
Chun also said that the two senior Amazon executives would be individually liable if a jury sides with the FTC due to the level of oversight they maintained over the Prime enrollment and cancellation process.
Amazon’s Prime boss Jamil Ghani and Neil Lindsay, a senior vice president in its health division who previously oversaw Prime’s technology and business operations, are named defendants in the complaint.
Russell Grandinetti, Amazon senior vice president of international consumer, is also named in the suit, but Chun argued he had “less involvement in the operation of the Prime organization” compared to Ghani and Lindsay.
Chun also scolded attorneys for Amazon in July for withholding thousands of documents from the FTC and abusing a legal privilege to shield them from scrutiny. Among the documents was a 2020 email where Amazon’s retail chief Doug Herrington said “subscription driving” was a “shady” practice and referred to Bezos as the company’s “chief dark arts officer.”
Representatives from Amazon didn’t immediately respond to a request for comment.
Amazon also faces a separate lawsuit brought by the FTC in 2023 accusing it of wielding an illegal monopoly. That case is set to go to trial in February 2027.
The Prime case is part of the FTC’s broader crackdown on so-called “dark patterns,” which it began examining in 2022. The phrase refers to deceptive design tactics meant to steer users toward buying products or services or giving up their privacy.
The agency brought a similar dark patterns lawsuit against Uber in April, accusing the ride-hailing and delivery company of deceptive billing and cancellation practices tied to its Uber One subscription service. Uber has disputed the FTC’s allegations.
Earlier this year, it reached settlements with online dating service Match and online education firm Chegg over claims that their subscription practices were deceptive or hard to cancel.
