The Samsung Galaxy Ring has various sensors to track things like heart rate.

BARCELONA — Samsung’s Galaxy Ring, its latest wearable, is launching with health-tracking features including heart rate and sleep monitoring while also giving users a score of their readiness for the day, a top executive told CNBC.

In a wide-ranging interview, Hon Pak, the head of the digital health team at Samsung Electronics, discussed the company’s first foray into the product category of rings, considerations for a subscription model for the Samsung Health app, and his vision for an artificial intelligence “coach.”

Samsung teased the Galaxy Ring in January during the press conference when it launched the S24 smartphone. The South Korean tech giant is putting it on display for the first time at Mobile World Congress in Barcelona, which kicks off on Monday.

Samsung Galaxy Ring features

Pak said the ring, which is fitted with sensors, will be able to give readings on heart rate, respiratory rate, the amount of movement made during sleep, and the time it takes a person to fall asleep once in bed.

He also said the ring will be able to give a user a “vitality score” which “collects data about physical and mental readiness to see how productive you can be.”

All of that will be accessible through the Samsung Health app.

The ring is set to go on sale this year, but Pak did not give a timeline or the pricing.

Pak also said the company is considering adding a feature that would allow the Galaxy Ring to do contactless payments, as with smartphones.

“We have a whole … team that is looking at that. But I think clearly looking at multiple different use cases for the Ring beyond just health, for sure,” Pak said.

The Samsung executive also said the company is working on non-invasive glucose monitoring as well as a blood pressure sensing through its wearable devices.

“I think we have some ways to go,” Pak said of non-invasive glucose monitoring. Currently, people use devices that pierce the skin to check glucose levels. A non-invasive way to do that would be a huge step.

Samsung ecosystem play

Samsung is hoping that various devices will boost its positioning in health, an area it has been working on for several years.

Samsung has its smartphones and smartwatches. The Galaxy Ring is the newest product category in health. Samsung said the decision to launch a “smart ring” was driven by its customers.

“Our own customers told us, I want choice. I want the ability to have other forms of wearables to measure health,” Pak said. “And some want to wear the watch, some want to wear the watch and the ring and get benefit from both. Some just want more simplicity.”

The Samsung Galaxy Ring will work in conjunction with Samsung’s smartwatches.

Pak confirmed that when the smartwatch and Ring are worn together, users will be able to get different health insights.

Samsung is not the first company to launch smart rings. There are a handful of other players such as Oura.

Previous generations of Samsung’s flagship smartphone, such as the S7, have sensors that track things like heart rate. Users could put their finger on the sensor and it would give a reading. Samsung has done away with those sensors on its phones, especially since it has smartwatches that offer these features.

However, Pak did not rule out the possibility that future smartphones would have health sensors on them.

“Mobile is still very pervasive and so I think there are reasons why we may want to put a sensor on a mobile versus having it on a wearable,” Pak said.

AI ‘coach’

Pak discussed how artificial intelligence will play a role in Samsung’s health services. AI can help make sense of all of the data these devices are collecting. And ultimately, Pak’s goal is to get the AI to give deeper insights into a person’s health.

He said large language models, which are AI models trained on huge amounts of data and that underpin applications like chatbots, can help to give greater insights.

“Imagine that large language model, acting as my digital assistant, while looking at the context of my medical records, my physiological data, my engagement with a mobile device, the wearables during all of that … begins to bring greater insights and personalization opportunities,” Pak said.

“There’s a digital assistant coach in the future, because we think that’s absolutely needed,” the Samsung executive said.

Pak described a scenario in which a digital assistant offers health advice in the right tone and context, saying “our ability to change our behavior becomes much greater.”

Bixby, Samsung’s digital assistant, could have a part to play, Pak said.

“So we are exploring various different ways in which the human computer interface will change over time … And so we think Bixby with speech represents a significant part of that option. But we don’t think it’s the only option. But Bixby potentially combined with large language models can be a phenomenal game changer. And we’re obviously having that conversation,” Pak said.

The executive also said the company is “considering” a subscription service for its Samsung Health app, but that the capabilities and insights it offers need to be improved before that can happen. AI assistants can help.

“If you’re gonna really make me pay for something, you better give me something that’s more end to end that’s more comprehensive” in terms of health insights, Pak said.

Google and Nvidia VC arms back vibe coding startup Lovable at $6.6 billion valuation

Google and Nvidia VC arms back vibe coding startup Lovable at .6 billion valuation

The VC arms of Google and Nvidia have invested in Swedish vibe coding startup Lovable’s $330 million Series B at a $6.6 billion valuation, the company announced on Thursday.

The news confirms an earlier story from CNBC, which reported on Tuesday that Lovable had raised at that valuation, trebling its valuation from its previous round in July, and that the investors included U.S. VC firms Accel and Khosla Ventures.

CapitalG, one of Google’s VC divisions, and Menlo Ventures led the round. Alongside Accel and Khosla, Nvidia venture arm NVentures, actor Gwyneth Paltrow’s VC firm Kinship Ventures, Salesforce Ventures, Databricks Ventures, Atlassian Ventures, T.Capital, Hubspot Ventures, DST Global, EQT Global, Creandum and Evantic also participated.

The fresh funds take Lovable’s total raised in 2025 to over $500 million.

"Everyone can be a developer of software," says Lovable CEO

“Lovable has done something rare: built a product that enterprises and founders both love,” said Laela Sturdy, managing partner at CapitalG in a statement accompanying the announcement.

“The demand we’re seeing from Fortune 500 companies signals a fundamental shift in how software gets built.”

Lovable’s platform uses AI models from providers like OpenAI and Anthropic to help users build apps and websites using text prompts, without technical knowledge of coding.

The startup reported $200 million in annual recurring revenue (ARR) in November, just under a year after achieving $1 million in ARR for the first time. It was founded in 2023 by Anton Osika and Fabian Hedin.

Vibe coding startups have seen big interest from VCs in recent times, as investors bet on their promise of drastically reducing the time it takes to create software and apps.

In the U.S., Anysphere, which created coding tool Cursor, raised $2.3 billion at a $29.3 billion valuation in November. In September, Replit hit a $3 billion price tag after picking up $250 million and Vercel closed a $300 million round at a $9.3 billion valuation.

Micron Technology‘s stock jumped 15% after the company signaled robust demand for its memory chips and blew away fiscal first-quarter estimates.

During an earnings call with analysts, Micron, which makes memory storage used for computers and artificial intelligence servers, said data center needs have fueled greater demand for its products.

Micron said it expects the total addressable market for high-bandwidth memory to hit $100 billion by 2028, growing at a 40% compounded annual growth rate. Management also upped its capital expenditures guidance to $20 billion from $18 billion.

“We are more than sold out,” said business chief Sumit Sadana. “We have a significant amount of unmet demand in our models and this is just consistent with an environment where the demand is substantially higher than supply for the foreseeable future.

Micron topped Wall Street estimates for the fiscal first quarter and issued blowout guidance.

The company reported adjusted earnings of $4.78 per share on $13.64 billion in revenue, surpassing LSEG estimates for earnings of $3.95 per share and $12.84 billion in sales.

Revenues in the current quarter are expected to hit about $18.70 billion, blowing past the $14.20 billion expected by LSEG. Adjusted earnings are forecast to reach $8.42, versus expectations of $4.78 per share.

JPMorgan upped its price target on the stock following the results, citing the favorable pricing setup, while Bank of America upgraded shares to a buy rating.

Morgan Stanley called the results the best revenue and net income upside in the “history of the U.S. semis industry” outside of Nvidia.

“If AI keeps growing as we expect, we believe that the next 12 months are going to have broader coat tails to the AI trade than just the processor names and memory would be the biggest beneficiary,” analysts wrote.

Here are five key things investors need to know to start the trading day:

1. Trump on defense

President Donald Trump, with approval ratings sagging, touted his economic and other policies in a White House address, taking jabs at his predecessor, former President Joe Biden. “I inherited a mess,” Trump said, referring to when he returned to the White House last January. “And I am fixing it.”

Here’s what to know:

  • Trump projected “the largest tax refund season of all time” thanks to the tax and spending package he signed into law over the summer.
  • The president also announced a “warrior dividend” of $1,776 for 1,450,000 U.S. military members, that’s set to cost about $2.5 billion.
  • The address came as Trump’s approval ratings are sagging across the board, on issues ranging from immigration to inflation, and as Republicans seek to hold on to majorities in the House and Senate in the 2026 midterms.
  • Obamacare subsidies extension will go to a vote after 4 Republicans bucked leadership.
  • Meanwhile, FBI Deputy Director Dan Bongino said he will step down in January.
  • The U.S. government admitted fault, citing missteps by members of the U.S. Army and the FAA, in the fatal collision of an Army Black Hawk Helicopter with an arriving American Airlines regional jet in January that took 67 lives.

2. Return of the CPI

The November consumer price index report, the first since the record government shutdown ended last month, is due out at 8:30 a.m. ET.

Economists surveyed by Dow Jones expect it to show a 12-month inflation rate of 3.1%. When excluding food and energy, core CPI is forecast to post an annual rate of 3.0%.

The Bureau of Labor Statistics has said the release “will not include 1-month percent changes for November 2025 where the October 2025 data are missing,” because the agency canceled the October inflation report in late November, weeks before the Federal Reserve’s final meeting of the year.

3. Time for a rebound?

Stock futures were ticking up ahead of the return of the monthly inflation report.

Micron Technology jumped 10% in premarket trading after its latest results and forecast topped Wall Street estimates. Shares of Olive Garden parent Darden rose premarket on an improved sales outlook.

The S&P 500 and Dow Jones Industrial Average ended the previous session lower for the fourth day in a row. Oracle had dropped more than 5% after the Financial Times reported that the cloud infrastructure company’s primary investor pulled out of its $10 billion Michigan data center.

Trump Media and Technology Group on Thursday announced a merger agreement valued at more than $6 billion with TAE Technologies, a fusion power company, showing the company that operates President Donald Trump‘s Truth Social platform is branching out even further.

4. Healthy IPO market

Shares of medical supply giant Medline, which makes everything from hospital beds to scrubs, jumped 41% in their Nasdaq debut Wednesday as the world’s biggest IPO of the year. The stock opened at $35, up from its $29 IPO price, and ended its first trading day at $41 a share, bringing Medline’s market capitalization to roughly $54 billion.

Just over 200 IPOs have priced this year despite market volatility in the spring, driven by President Donald Trump’s sweeping tariffs and the longest U.S. government shutdown in history in the fall. It is the largest U.S. listing since Rivian‘s $13.7 billion deal in November 2021, according to data compiled by CNBC.

Delta Air Lines President Glen Hauenstein, who helped shape Delta into the industry’s profit leader, will retire at the end of February. Hauenstein, who joined Delta 20 years ago, led the airline’s lucrative embrace of travelers willing to spend more for a more luxurious trip, or at least a few more inches of legroom on board.

Some of Delta’s strategies became too successful for customers’ tastes, such as its popular airport SkyClubs, which Delta recently raised the entry bar.

The Daily Dividend

And the winner is…YouTube. In a major shift away from traditional television, the Academy of Motion Picture Arts and Sciences announced Wednesday it’s signed a multiyear deal with the Google-owned service to stream the Oscars starting in 2029 and running through 2033, red carpet coverage included.
