Dexcom on Tuesday announced an artificial intelligence feature for its Stelo continuous glucose monitor that gives users a personalized look into how meals, sleep and activity impact their glucose levels. It’s the first iteration of a new generative AI platform that the company has been building with Google Cloud. 

Stelo is an over-the-counter CGM that pokes through the skin to measure real-time blood sugar levels. The sensor launched in August and can be used by any adult who doesn’t take insulin. 

The report reflects Dexcom’s effort to make Stelo more personalized and engaging for consumers as it works to penetrate a new market. 

“The No. 1 feedback we get is users want to see more,” Jake Leach, chief operating officer at Dexcom, told CNBC in an interview. “They’re making an investment and wearing the product, and they want to be able to take the most advantage of all the data that they’re generating.”

Dexcom is using Google’s Gemini models and its Vertex AI platform as the foundation for its new AI offering. Vertex AI allows developers to build applications that synthesize different types of data, which can be notoriously challenging in health care. 

Leach said Dexcom is also exploring how its generative AI platform can be used across its other CGM products, but the company is proceeding extra carefully since patients rely on them to prevent medical emergencies. 

“It really felt like Stelo was the right place to do this for the first time,” he said.

An existing insights report has already been available to users within the Stelo app, but it followed a more standard template format each week. Dexcom believes the AI-generated report will be more valuable to users since it’s personalized, Leach said. 

If there’s a week where a user is not moving enough after meals, for instance, the report would include relevant tips and educational materials to help. 

Stelo’s AI reports don’t give users medical advice, though Dexcom has been using an AI framework from the U.S. Food and Drug Administration to help guide the feature’s development, Leach said. The FDA approved Stelo in March. 

Eventually, Dexcom wants to use its generative AI platform to deliver real-time feedback to users instead of just weekly reports. The company is also exploring how the technology could act as a predictive indicator for potential problems, much like a check engine light on a car. 

“It gives you a sense for what could be going on, and recommendations of where you might want to go to seek more advice,” Chris Sakalosky, vice president of strategic industries for Google Cloud, told CNBC in an interview.   

Dexcom’s updated weekly report began rolling out to Stelo users this week.

Joby lawsuit accuses air taxi rival Archer of using stolen information to ‘one-up’ deal

Joby lawsuit accuses air taxi rival Archer of using stolen information to 'one-up' deal

Air taxi maker Joby Aviation in a new lawsuit accused competitor Archer Aviation of using stolen information by a former employee to “one-up” a partnership deal with a real estate developer.

“This is corporate espionage, planned and premeditated,” Joby said in the lawsuit filed Wednesday in a California Superior Court in Santa Cruz, where the company is based.

Archer and Joby did not immediately respond to CNBC’s request for comment.

The lawsuit alleges that former U.S. state and local policy lead, George Kivork, downloaded dozens of files and sent some content to his personal email two days before he resigned in July to take a job at Archer, which had recruited him.

By August, Joby said a partner that worked with Kivork said it had been approached by Archer with a “more lucrative deal.” Joby alleges that the eVTOL rival’s understanding of “highly confidential” details helped it leverage negotiations.

Joby also said the developer attempted to terminate the agreement, citing a breach of confidentiality.

Kivork refused to return the files when Joby approached him after conducting an investigation, according to the suit. The company also said Archer denied wrongdoing, and would not disclose how it learned about the terms of the agreement or provide results from an internal investigation it allegedly undertook.

The lawsuit comes during a busy period for electric vertical takeoff and landing (eVTOL) technology as companies race to gain Federal Aviation Administration certification to start flying commercially. ‘

The sector has also benefitted from President Donald Trump‘s newly minted eVTOL pilot program.

Joby argued in the complaint that it’s “imperative” to protect Joby’s work “from this type of espionage” to promote the sector’s success and ensure fair competition.

Last week, Joby said it completed its first test flight for a hybrid aircraft it’s working on with defense contractor L3Harris. This month, Amazon-backed Beta Technologies, another electric flight company, also went public on the New York Stock Exchange.

Joby shares have more than doubled over the last year, while Archer is up about 68%.

In August 2023, Archer settled a previous legal dispute with Boeing-owned Wisk Aero over the alleged theft of trade secrets. As part of the deal, Archer agreed to use Wisk as its autonomous tech partner.

A hearing is scheduled for March 20, 2026.

Bitcoin falls to lowest level since April

Bitcoin dropped on Thursday to levels not seen in more than six months, as investors appeared to pull back exposure to riskier assets and weighed the prospects of another Federal Reserve rate cut next month.

The flagship digital currency fell to as low as $86,325.81, its lowest level since April 21. It last traded at $86,690.11.

The release of stronger-than-expected U.S. jobs data raised questions about whether the central bank would lower its benchmark overnight rate. The U.S. economy added 119,000 in September, well above the 50,000 economists polled by Dow Jones expected.

That report sent the probability of a December rate cut to around 40%, according to the CME Group’s FedWatch tool.

Bitcoin’s pullback formed part of a broader cryptocurrency market decline. XRP was last down 2.3% on the day, and is below $2.00, while ether shed more than 3% to trade well below $3,000. Dogecoin was unchanged.

The world’s oldest crypto also led stocks lower, even after a blockbuster Nvidia earnings report. Traders who are heavily invested in AI-related stocks tend to also hold bitcoin, linking the two trades.

Bitcoin’s price has largely slid since a rash of cascading liquidations of highly leveraged crypto positions in early October.
