Stripe has hit a $159bn valuation, according to a recent letter from company founders.

Irish fintech giant Stripe is considering acquiring some or all of PayPal, reports Bloomberg, citing insiders.

According to the publication, Stripe has already expressed preliminary interest in a potential acquisition of the US payments company or some of its assets. Stripe declined to respond to queries put forth by SiliconRepublic.com. PayPal has not yet responded.

PayPal share prices shot up by around 6.74pc since Bloomberg first reported the story yesterday (24 February).

The US company, which went public in 2002, has a market capitalisation of $43.2bn. The 2010-founded Stripe was valued at $159bn earlier this week. Stripe’s co-founders are seemingly in no rush to take the company public.

Founded in the late 1990s, PayPal has struggled to modernise against emerging rivals in the payments space such as Apple and Google.

Earlier this month, PayPal snatched HP’s CEO Enrique Lores to replace Alex Chriss, who struggled to revitalise the company after being hired during the post-pandemic period when faced with low trading volume and newer fintech rivals.

However, the executive switch-up did not sway investor confidence after the company missed revenue expectations in the quarter past, sending share prices down by 20pc. Company shares have dropped more than 80pc over the last five years.

Stripe, however, has remained “robustly profitable”, according to a letter from the founding brother-duo Patrick and John Collison. The company is investing heavily in product development and making strategic acquisitions that include programmable wallet company Privy, stablecoin orchestration platform Bridge and Metronome, which “powers the intricate usage-based billing models used by companies like OpenAI, Anthropic, Confluent and Nvidia”.

In September, Stripe launched a joint crypto venture called Tempo, which reportedly raised $500m at a $5bn valuation just weeks after coming out from stealth. In November, Swedish fintech giant Klarna become the first bank to launch a stablecoin on Tempo with KlarnaUSD. The coin is set to launch this year.

• Sam Altman describes current proposals for orbiting data centers as entirely unrealistic for this decade
• Modern AI chips cannot survive space radiation, making orbital data centers currently unfeasible
• Radiation-hardened semiconductor nodes lag behind advanced fabrication processes required for AI workloads

Sam Altman has publicly dismissed proposals to place large-scale data centers in orbit, describing the idea as unrealistic under current technological and economic conditions.

The OpenAI chief executive argued space-based computing infrastructure will not operate at a meaningful scale within this decade.

There has never been a “casual” way into Nagra. The Swiss manufacturer’s components are engineered like laboratory instruments and priced accordingly, which has historically placed the brand well beyond the reach of anyone not prepared to treat audio as a long term capital investment. Even so called entry level and mid-tier offerings such as the Compact Phono and PREAMP II-S demand serious financial commitment.

With the $7,500 Compact Player, Audio Technology Switzerland SA is addressing a long standing reality: for many listeners, Nagra has been admired from a distance. This model appears designed to narrow that gap without diluting the formula.

It is also important not to confuse it with the Compact Streamer. That unit relies on an external DAC, while the Compact Player is a complete digital front-end with its own internal conversion stage and analog output section. In practical terms, this makes it a far more self contained solution for systems that are not already built around a separate Nagra DAC.

What the Compact range does not yet include is a dedicated Compact preamplifier or power amplifier. Whether those arrive later remains to be seen. For now, the direction seems clear: these components function as a gateway. They allow owners to introduce a more attainable slice of Nagra into an existing system rather than requiring a full top to bottom commitment from day one.

But make no mistake, should a complete Nagra Compact Series emerge, the final system price is likely to be in the $25,000 to $30,000 range and that’s before adding loudspeakers, cables, and a turntable or CD player.

The Compact Player, however, is not positioned as a compromise piece. It is a deliberate entry point into the ecosystem, and from personal experience, Nagra components tend to reward those who keep things in the family; which is unlikely to make your accountant very happy.

Lower Barrier to Entry, Full Swiss Engineering Inside

The Nagra Compact Player is a fully integrated network player and DAC built around the company’s established engineering priorities rather than feature chasing. It combines a modern streaming platform with a dedicated D/A conversion stage and a true dual mono analog output section, with separate circuitry for each channel to improve separation and reduce crosstalk.

The digital architecture centers on a high performance DAC followed by a carefully implemented analog stage. Nagra has paid close attention to clock design, power supply regulation, and PCB layout to keep jitter and noise low and preserve signal integrity through the entire conversion path. This is not unusual for the brand, but it matters in a product designed to serve as a primary source.

Format support is comprehensive. The Compact Player handles PCM up to 384 kHz 32 bit and DSD256, whether streaming from supported services or playing locally stored files via UPnP DLNA or USB storage. Measured performance includes a noise floor of -140 dB A weighted and a 14 ohm output impedance, which makes it easy to integrate with a wide range of preamplifiers and integrated amplifiers. It can also be connected directly to a power amplifier or active loudspeakers if system design calls for it.

Control is handled through the free mConnect app, available for iOS and Android phones and tablets. The app manages local file playback, network streaming, and firmware updates, keeping day to day operation centralized in a single interface.

Streaming support is comprehensive and current. The Compact Player supports Qobuz Connect, TIDAL Connect, and Spotify Connect for direct in app control, along with AirPlay 2 for Apple devices. It is both Roon Ready and Roon Tested, integrates with Audirvana, and provides access to thousands of internet radio stations via vTuner. Local music libraries can be accessed over UPnP DLNA or through attached USB storage.

It connects to your network via Ethernet and can also access music stored on a USB hard drive or memory stick. Analog output is via standard RCA connectors, so it will work with most preamplifiers and integrated amplifiers without any special requirements.

Power draw is modest. It runs on an external 12V DC supply and consumes about 10 watts, which is low enough for continuous operation without concern. That figure can rise slightly if a USB hard drive is attached, but not in a way that materially affects ownership.

Physically, it lives up to its name. Measuring 185 x 166 x 41 mm (7.2 x 6.5 x 1.6 inches) and weighing 1.9 kg (4.1 lbs), it is compact enough to fit easily on a standard shelf or rack without demanding extra space.

The chassis is CNC machined from solid aluminum, providing the rigidity and mechanical stability expected at this level. It is compact by Nagra standards, which makes it easier to integrate into real world systems without sacrificing build quality.

For those who want to take it further, the optional Compact PSU offers improved regulation and current delivery. Nagra also supports additional mechanical isolation and vibration control accessories aimed at refining resolution and spatial precision.

The Bottom Line

The Compact Player is for listeners who want an integrated network player and DAC built to Nagra’s standards, but who may not be ready to commit to a full reference stack. It makes the most sense for existing Nagra owners, or for serious two channel listeners looking to anchor a high performance system with a compact, all in one digital front end.

That said, context matters. Below $1,000, brands like WiiM, Bluesound, Eversolo, and Cambridge Audio offer network players and DACs with extensive feature sets and strong measured performance at a fraction of the cost. On the other end, companies such as Aurender and Innuos sit closer to this price tier with more elaborate server based solutions.

The Compact Player does not try to win on price or feature count. It competes on execution, integration, and long term system building within the Nagra ecosystem. For buyers who value that approach and are comfortable with the investment, it is a deliberate and logical entry point.

Samsung’s Galaxy S26 Ultra is here, packing a wealth of upgrades from the design to its fancy new Privacy Display, which aims to keep people from spying on whatever shady things you’re up to on your commute. But the Ultra range has always been where Samsung has unleashed its latest, greatest camera technology, so let’s take a closer look at what’s new for the photographers among you. 

In terms of hardware, not a lot has changed. The main camera has a 200-megapixel resolution, a 50-megapixel ultrawide-angle camera, and 10-megapixel 3x telephoto and 50-megapixel 5x telephoto cameras. Those specs are the same as the previous S25 Ultra, so those of you hoping for a wild overhaul of the cameras to keep pace with Xiaomi’s upcoming 17 Ultra may be disappointed.

But there have been some tweaks. The main and ultrawide cameras now have wider apertures, which should help capture more light and be especially useful in low-light situations. In fact, Samsung especially highlighted the improved performance of night mode imagery for both stills and video, with the night video mode employing more advanced software processing for noise reduction and improved colors. 

Speaking of video, it’ll still shoot in 8K and supports Log codecs with built-in LUTs (which is what cinema pros call filters, essentially), which should make the phones more appealing to serious video creators. To show the phone means business, Samsung took a leaf out of Apple’s playbook and filmed and livestreamed its San Francisco launch event using the S26 Ultra.

There’s also a feature called Horizon Lock, which aims to keep the horizon level while shooting video, no matter how you twist and turn your phone. This kind of stabilization exists in action cameras already, and it can be helpful for filming intense action, like if you’re running to keep up as you’re filming your friend skateboarding. 

But because it’s 2026 and AI is the word on every tech company’s lips, many of the major updates come in the form of generative AI. It’s built deep into the camera experience, allowing you to use natural language prompts to edit images, including compositing one element of an image onto another, or even changing the outfit someone in your image is wearing. 

During its Unpacked event, Samsung demoed the features, showing how its AI tools can take a picture of a dog and place it in the arms of a girl in another image. The company also showed how the phone can instantly change a woman’s outfit from a simple shirt to a cosy sweater, and then to a more grungy skater aesthetic.

To be fair, the images looked photo-realistic — at least as far as I could see on the YouTube livestream — though how these tools actually work in everyday use remains to be seen until we spend some time with them. The bigger question is whether you actually need them. I won’t answer that for you, but I will say that I’m disappointed that Samsung is following the trend of using AI gimmicks as the main upgrades for its cameras rather than focusing on taking better pictures in the real world. 

I’ll reserve judgment until I’ve had some time to take images around my beautiful home city of Edinburgh, Scotland. There, I’ll focus on finding out how well the phone can capture photographs I’d want to share with family and friends, not just how easily I can put on a fake sweater. 

Tecno just unveiled a rather intriguing at MWC 2026. The standout feature here is likely the size. Most modular smartphone concepts start bulky and only get bulkier once attaching accessories. Tecno’s base smartphone is just 4.9mm thin, which is significantly thinner than a pencil .

Of course, the size increases with each attached module. However, snapping on the power bank module makes the thickness comparable to a standard modern smartphone. Another key feature here is how these various modular components stick together. Tecno has developed new interconnection technology that uses both magnets and pin connectors. This should make it easy to both attach and remove components.

The company says this phone has been designed to grow with the user through hardware expansion. To that end, Tecno has developed 10 modules. There are various camera lenses and something that looks like a dedicated gaming controller.

While the magnets are for attaching, the pin connectors assist with power delivery. Data transmission between the phone and the modules is handled wirelessly, with the ability to switch between Wi-Fi, Bluetooth and mmWave depending on where the user is located.

There are two colorways for both the phone and the ecosystem of accessories. There’s a silver-aluminum edition and a nifty-looking grey version. This doesn’t matter to actual consumers because, well, it’s just a concept design. It does look like the company’s magnetic attachment technology could make it to some actual products down the line.

Tecno has always been a company that marched to the beat of its own drummer. It has developed a , a model with a and a foldable with a .

The industry hasn’t quite embraced modular smartphones just yet, even though there have been some nifty concept designs. Google’s goes back more than a decade, and the same can be said of that never saw the light of day.

There have been some modular phones released to the real world, but they weren’t nearly as ambitious as Tecno’s concept. LG launched a semi-modular phone , but it . Moto has also released a , but they didn’t set the world on fire.

The Sea-Scan research team from Trinity College Dublin has been awarded the Defence Innovation Challenge top prize, for its AI-enhanced real-time vessel detection system.

Given the growing threats to subsea communications and energy infrastructure, the need for continuous, reliable monitoring of Ireland’s maritime environment has come to the fore in recent years. This was reflected in the winning project at today’s announcement.

This morning (25 February), Irish Minister for Further and Higher Education, Research, Innovation and Science James Lawless, TD and Minister for Defence Helen McEntee, TD announced more than €1.8m in prize phase funding under the co-funded Research Ireland – Defence Innovation Challenge, with Trinity College Dublin-based project Sea-Scan winning the top award.

The Sea-Scan research team is working on a next-generation maritime situational awareness project to strengthen Ireland’s naval security. The Mash – Mobile Adaptable Shelter – team, led by Dr Daniel McCrum and Dr Kevin Roche from University College Dublin and Defence Forces liaison Captain Dave McKenna, was awarded runner-up funding.

Ireland’s ability to monitor maritime activity, including the detection of so-called “dark” vessels, has been much in the headlines in recent year, with fears over our ability to adequately protect the subsea cables that are the backbone of our international communications.

Sea-Scan will develop an AI-enhanced real-time vessel detection system to support early warning and improved situational awareness, while it also offers potential applications in environmental monitoring. The Sea-Scan team is led by Prof Marco Ruffini and Dr John Kennedy from Trinity College Dublin and Defence Forces liaison Commander Cathal Power. The prize funding was awarded under the Maritime Situational Awareness Challenge.

“Challenge-based research funding encourages researchers to work directly with those most affected by the problems they seek to address,” said Dr Diarmuid O’Brien, CEO of Research Ireland. “The teams being funded today have developed their solutions through close collaboration with Defence Forces personnel. The Sea-Scan team are developing a high-quality solution to a complex problem that will deliver a transformational capability for the Irish Defence Forces.”

“Maintaining strong awareness of activity in Ireland’s maritime domain is essential, particularly given the country’s role as an island nation and a key Atlantic gateway for digital connectivity,” said Ruffini.

“As subsea communications and energy infrastructure continue to grow in strategic importance, so too does the need for continuous, reliable monitoring of the surrounding maritime environment.”

Ruffini says the Sea-Scan team has demonstrated the potential to detect and characterise vessel activity using existing subsea fibre infrastructure, “showcasing a robust sensing capability embedded within operational communications assets and enabling effective vessel monitoring and subsea infrastructure protection”.

“The prize‑winning projects demonstrate how cutting‑edge research can deliver practical, real‑world solutions that strengthen national security while driving technological innovation,” said Lawless.

“Innovation is critical to ensuring our Defence Forces have the tools they need to operate effectively in an increasingly complex environment,” said McEntee. “This investment reflects our commitment to modernising defence capabilities and embracing innovative solutions for the future.”

When Alan Cole saw Elon Musk fans eagerly bidding up a contract on the prediction market Kalshi that the Department of Government Efficiency (DOGE) could effectively reduce federal spending in a year, he knew he had to take the bet, according to a story about Cole’s winnings in the Wall Street Journal.

If Cole, an international tax accountant, knew anything in life it was this: federal spending couldn’t be quickly whacked, he told the WSJ. Even if DOGE nixed some federal contracts and laid off workers (which it did), plenty of remaining obligations and the skyrocketing federal debt would remain.

So, he wagered his entire life savings — over $342,000 — to take the counter bet that the U.S. federal budget wouldn’t insta-shrink. He slowly amassed 3% of a Kalshi prediction market that had grown to $12 million (making a few hedging bets along the way), he told the WSJ.

When the government released the 2025 year-end spending report on February 20, showing increases compared to 2024, Cole walked away with $470,300 and a handsome $128,000 profit.

Japan’s SoftBank will be the first to deploy the new SN50 chips, while Intel is partnering with SambaNova to roll out its Intel-powered AI cloud.

Intel-backed Nvidia rival SambaNova has raised $350m in a Series E round led by Vista Equity Partners and Cambium Capital, with strong participation from Intel Capital.

Reuters was first to report the planned raise earlier this month. While details of the investment were not disclosed at the time, sources had told the publication that Intel Capital’s contribution would be around $100m, with potential commitments of up to $150m.

Other participants in the round included Gulf Development, Assam Ventures, Battery Ventures, Atlantic Bridge, GV and BlackRock.

According to SambaNova, proceeds from the raise will be used to expand the production of the company’s newly introduced SN50 chip – touted to deliver “the best tokens per watt” – as well as to scale ‘SambaCloud’ and deepen enterprise software integrations.

SoftBank will be the first to deploy SN50 within its AI data centres in Japan, powering inference services for sovereign and enterprise customers across the Asia-Pacific.

Intel has close ties with the 2017-founded SambaNova, with CEO Lip-Bu Tan serving as chairperson on SambaNova’s board. Alongside the raise, the two companies have also jointly announced a multi-year collaboration to deliver cost-efficient AI inference solutions for AI companies, model providers, enterprises and governments worldwide.

As part of the collaboration, Intel is making a strategic investment in SambaNova to accelerate the rollout of an Intel-powered AI cloud.

“AI is no longer a contest to build the biggest model,” said Rodrigo Liang, co‑founder and CEO of SambaNova.

“With the SN50 and our deep collaboration with Intel, the real race is about who can light up entire data centres with AI agents that answer instantly, never stall, and do it at a cost that turns AI from an experiment into the most profitable engine in the cloud.”

The company positions itself as a rising competitor looking to take some of Nvidia’s gigantic share in the AI chips market. Liang, who previously worked as an executive at cloud provider Oracle, said in 2024 that Nvidia had “lost some of its sheen” and that “rivals are biting at its heels”.

Kevork Kechichian, the executive vice-president and general manager for Intel’s data centre group, said: “Customers are asking for more choice and more efficient ways to scale AI.

“By combining Intel’s leadership in compute, networking and memory with SambaNova’s full-stack AI systems and inference cloud platform, we are delivering a compelling option for organisations looking for GPU alternatives to deploy advanced AI at scale.”

Other companies are also looking for alternatives to Nvidia. Meta yesterday (24 February) said that it would buy billions of dollars’ worth of AMD’s chips to develop AI tech and power new data centres. The deal could see Meta taking a stake of up to 10pc in AMD.

Earlier this month, Cerebras Systems, which also positions itself as a rival to Nvidia, raised $1bn in a Series H round led by Tiger Global with participation from AMD. In January, Cerebras and its early backer OpenAI announced a partnership to deploy 750MW of Cerebras’s wafer-scale systems to make OpenAI’s chatbots faster.

Positron, another Nvidia competitor that offers energy-efficient AI chips for inference, raised $230m from Arm Holdings and the Qatar Investment Authority in recent weeks, taking its valuation above $1bn.

Wearables startup CUDIS is launching its newest series of health rings this week. The updated ring comes equipped with a number of features, including an AI “agent coach” designed to keep users on track to attain their fitness goals.

CUDIS says it differentiates itself from other wearables by not just delivering health metrics but also incentivizing healthy behavior through a points system. Users garner digital “health points” for healthy behaviors — things like daily sleep, 10,000 steps every day, sports activities, and conversations with the ring’s AI coach — which can then be redeemed through an integrated marketplace for discounts on health supplements and other products.

The ring’s AI Agent Coach, meanwhile, is designed to leverage generative AI to aid with healthy programs for exercise and daily health. The company says that its agent generates tailored programs including “daily tasks, recovery protocols, supplement recommendations, and direct referrals to licensed medical professionals.”

The ring also tracks a host of body metrics and daily behaviors, such as sleep quality, stress management, movement, and recovery. This helps them see how these metrics affect their Pace of Aging (PoA), showing whether their body is aging faster or slower than their chronological age, the company explains.

CUDIS CEO and co-founder Edison Chen told TechCrunch that since his company’s first wearable was launched in 2024, the company has sold over 30,000 units across its first two models. The app’s user base has also grown to 250,000 users across 103 countries, he added.

“Our strongest markets so far have been North America, Europe, and Asia,” Chen said. “What we’re good at is pattern recognition for healthy people trying to optimize,” Chen told TechCrunch.

“The AI spots when you’re trending in the wrong direction, such as chronic poor sleep, declining HRV, elevated resting heart rate, and either suggests lifestyle changes or connects you to a professional. The control is in the escalation pathway to the right care access,” he said.

The company claims that it keeps user data encrypted and secure via the Solana blockchain. It has previously been described as a “web3 AI wellness company.” (TechCrunch was not able to test the smart ring directly to verify its security claims.)

CUDIS announced $5 million of seed funding in 2024. The round was led by Draper Associates and included a number of other investors, including a number of blockchain-associated investor groups like Skybridge, DraperDragon, Monke Ventures, and Foresight Ventures, among others. The company also plans to launch a Kickstarter soon.
