Samsung on Wednesday launched three new folding smartphones — including thinner top-end devices and a cheaper version of its flip phone — as the tech giant looks to entice buyers to make the switch to foldables.

The main new additions to Samsung’s foldable phone range are the Galaxy Z Fold 7, which folds like a book, and the Galaxy Z Flip 7, which takes on the form of the classic clamshell-style flip phones. Samsung also announced a cheaper version of its latest flip phone, the Galaxy Z Flip 7 SE.

The South Korean consumer electronics giant is refreshing its foldable phone lineup at a time when the company faces increased competition from Chinese rivals, such as Honor and Oppo. Last week, Honor — which spun off from Chinese tech giant Huawei in 2020 — launched the new ultra-thin Magic V5 folding phone, while Oppo introduced its own slim foldable device, the Find N5, earlier this year.

Samsung’s share of the global foldable phone market slipped to 45% in 2024 from 54% a year earlier, according to Counterpoint Research. China also accounts for a significant share of the foldables market — although 17.2 million of these devices were sold last year globally, this drops to 9.4 million when excluding mainland China.

Thinner and bigger — but there’s a catch

The Galaxy Z Fold 7 is super thin at a thickness of 8.9 millimeters (0.35 inches) closed and only 4.2 millimeters open. It’s also much lighter than its predecessor, weighing 215 grams (7.62 ounces). These stats put the phone on par with both Honor’s Magic V5 and the Oppo Find N5.

The new Fold device has a 6.5-inch cover screen and an 8-inch main display when opened, making it bigger than its predecessor.

It’s also decked out with premium new cameras, featuring a 200-megapixel main lens, as well as a 10-megapixel telephoto sensor, 12-megapixel ultra-wide and two 10-megapixel front cameras on both the cover screen and on the main display.

Samsung’s new Fold generation is, nevertheless, much more limited than other devices in the market when it comes to battery capacity. The Galaxy Z Fold 7 has a 4,400 milliampere-hour (mAh) battery — far less than the 6,100 mAh power pack in Honor’s Magic V5’s or the Oppo Find N5’s 5,600 mAh battery.

Samsung says its device is capable of 24 hours of video playback.

The Galaxy Z Fold 7 will retail in the U.K. at a starting price of £1,799 ($2,434).

Samsung’s Galaxy Z Flip 7 is also thinner than its predecessor, coming in at 6.5 millimeters when opened flat. By contrast, the Galaxy Z Flip 6 has a depth of 6.9 millimeters when unfolded.

The new phone has a 4.1-inch cover screen and a 6.9-inch main display. It comes with a 50-megapixel main camera and 12-megapixel ultra-wide sensor on the back and a 10-megapixel lens on the main display.

It also has a bigger 4,300 mAh battery, which Samsung says supports 31 hours of video playtime on a single charge.

In addition to Flip 7, Samsung is also introducing a cheaper version of the phone, called the Galaxy Z Flip 7 FE, which is slightly smaller and thicker than its more premium counterpart.

The Galaxy Z Flip 7 will retail from £1,049 in the U.K., while the Galaxy Z Flip 7 FE starts at £849.

It also has new AI-powered camera features, including one that automatically suggests people and objects to erase from photos — for example, if you’ve been photobombed by someone — and an audio eraser tool that proactively detects and removes unwanted background noise from videos.

The Galaxy Z Flip 7, meanwhile, lets you pull up Google’s AI assistant app, Gemini Live, on top of the camera app when taking a live video of yourself. Samsung says one use case this offers is the ability to ask the AI for tips on the outfit you’re wearing.

Sheng Win Chow, senior analyst at Counterpoint Research, said that physical design alone won’t be enough to convince users to convert to foldable phones from the touchscreen slabs we’re all used to.

“Lasting leadership depends on redefining what foldables do, not just how they look,” he said in an emailed note. “The next wave of competition will come from software — how vendors use the foldable form factor to deliver truly differentiated experiences.”

Musk says Tesla is expanding Austin robotaxi service, adding Grok to cars

Tesla CEO Elon Musk said the company is expanding its robotaxi service area and bringing xAI’s Grok to vehicles as it rolled out a new iteration of the artificial intelligence chatbot.

Shares gained about 3%.

Musk said on X that Grok, his AI chatbot that praised Adolf Hitler and posted a barrage of antisemitic comments recently, will be available in Tesla vehicles “next week at the latest.”

xAI officially launched the Grok 4 update overnight as the company continued to face backlash for the vitriol written by the chatbot.

In response to a user post on his social media platform X, Musk said the company is expanding its Austin, Texas robotaxi service area this weekend. He also said Tesla is awaiting regulatory approval for a launch in the Bay Area “probably in a month or two.”

The expansion of robotaxi and Grok integration comes at a fraught time for Musk and his empire.

Tesla set its annual shareholder meeting for Nov. 6, a Thursday filing showed. A group of investors recently called on the electric vehicle company to schedule the meeting.

Its last shareholder meeting was in June 2024, as Musk established himself as a major backer of President Donald Trump‘s reelection campaign. Musk later led the Trump administration’s Department of Government Efficiency, known as DOGE.

After stepping down from DOGE at the end of May, Musk has openly feuded with Trump on social media over the major tax bill, with the president suggesting the government look at cutting contracts for Musk’s companies.

Shares have tanked from their post-election high over investor concerns that the public fight could hamper Tesla. Slowing sales and rising competition also stifled some investor appetite.

Tesla shares fell Monday, with the company losing $68 billion in value after Musk continued to blast Trump’s “Big Beautiful Bill” and said he was establishing his own political party, the “America Party.”

The world’s richest man suffered another blow Wednesday when Linda Yaccarino stepped down as CEO of his social media platform X, leaving the role after a turbulent two years for the company.

Amazon Web Services is building equipment to cool Nvidia GPUs as AI boom accelerates

Amazon said Wednesday that its cloud division has developed hardware to cool down next-generation Nvidia graphics processing units that are used for artificial intelligence workloads.

Nvidia’s GPUs, which have powered the generative AI boom, require massive amounts of energy. That means companies using the processors need additional equipment to cool them down.

Amazon considered erecting data centers that could accommodate widespread liquid cooling to make the most of these power-hungry Nvidia GPUs. But that process would have taken too long, and commercially available equipment wouldn’t have worked, Dave Brown, vice president of compute and machine learning services at Amazon Web Services, said in a video posted to YouTube.

“They would take up too much data center floor space or increase water usage substantially,” Brown said. “And while some of these solutions could work for lower volumes at other providers, they simply wouldn’t be enough liquid-cooling capacity to support our scale.”

Rather, Amazon engineers conceived of the In-Row Heat Exchanger, or IRHX, that can be plugged into existing and new data centers. More traditional air cooling was sufficient for previous generations of Nvidia chips.

Customers can now access the AWS service as computing instances that go by the name P6e, Brown wrote in a blog post. The new systems accompany Nvidia’s design for dense computing power. Nvidia’s GB200 NVL72 packs a single rack with 72 Nvidia Blackwell GPUs that are wired together to train and run large AI models.

Computing clusters based on Nvidia’s GB200 NVL72 have previously been available through Microsoft or CoreWeave. AWS is the world’s largest supplier of cloud infrastructure.

Amazon has rolled out its own infrastructure hardware in the past. The company has custom chips for general-purpose computing and for AI, and designed its own storage servers and networking routers. In running homegrown hardware, Amazon depends less on third-party suppliers, which can benefit the company’s bottom line. In the first quarter, AWS delivered the widest operating margin since at least 2014, and the unit is responsible for most of Amazon’s net income.

Microsoft, the second largest cloud provider, has followed Amazon’s lead and made strides in chip development. In 2023, the company designed its own systems called Sidekicks to cool the Maia AI chips it developed.

Bitcoin hit a fresh record on Wednesday afternoon as an Nvidia-led rally in equities helped push the price of the cryptocurrency higher into the stock market close.

The price of bitcoin was last up 1.9%, trading at $110,947.49, according to Coin Metrics. Just before 4:00 p.m. ET, it hit a high of $112,052.24, surpassing its May 22 record of $111,999.

The flagship cryptocurrency has been trading in a tight range for several weeks despite billions of dollars flowing into bitcoin exchange traded funds. Bitcoin purchases by public companies outpaced ETF inflows in the second quarter. Still, bitcoin is up just 2% in the past month.

Bitcoin climbs above $112,000

On Wednesday, tech stocks rallied as Nvidia became the first company to briefly touch $4 trillion in market capitalization. In the same session, investors appeared to shrug off the latest tariff developments from President Donald Trump. The tech-heavy Nasdaq Composite notched a record close.

While institutions broadly have embraced bitcoin’s “digital gold” narrative, it is still a risk asset that rises and falls alongside stocks depending on what’s driving investor sentiment. When the market is in risk-on mode and investors buy growth-oriented assets like tech stocks, bitcoin and crypto tend to rally with them.

Investors have been expecting bitcoin to reach new records in the second half of the year as corporate treasuries accelerate their bitcoin buying sprees and Congress gets closer to passing crypto legislation.
