In 2012, Amazon founder Jeff Bezos was asked by TV host Charlie Rose whether his e-commerce company would ever venture into brick-and-mortar stores. Bezos said shoppers were well-served by existing physical retailers and that Amazon wasn’t interested in launching a “me-too” product.
“We want to do something that’s uniquely Amazon,” Bezos said. “If we can find that idea, and we haven’t found it yet, but if we can find that idea, we would love to open physical stores.”
Six years later, Amazon landed on a revolutionary retail concept that it hoped would transform how people shop in brick-and-mortar stores. The company launched its first Amazon Go convenience store featuring a new kind of technology, called “Just Walk Out.”
In practice, customers would be able to load up their cart and exit the store without standing in a checkout line. Amazon soon brought cashierless checkout to its Fresh supermarkets and two Whole Foods locations. In 2020, the company began licensing Just Walk Out technology to third parties, signing on retailers in stadiums, airports and hospitals.
But the company has since taken a sideways turn.
In April, Amazon announced it was removing cashierless checkout from its U.S. Fresh stores and Whole Foods locations, a move that coincided with CEO Andy Jassy’s efforts to rein in costs to meet rapidly changing macro conditions.
In place of Just Walk Out, which typically requires ceiling-mounted cameras, shelf sensors and gated entry points, Amazon Fresh stores and Whole Foods supermarkets will feature Dash Carts. The carts track and tally up items as shoppers place them in bags, enabling people to skip the checkout line. Amazon continues to use Just Walk Out in its grab-and-go marts and UK Fresh stores.

The main challenge for Amazon and other startups working on autonomous checkout is the need to scale it to enough locations and retail categories that it becomes a natural part of in-store shopping, said Jordan Berke, founder and CEO of retail consulting firm Tomorrow.
“Until that’s the case, it’s an uphill battle,” Berke said. “These technology providers, Amazon included, are going to have to subsidize and continue to invest to train the retailer, train the consumer, train the market, that this is a mainstream experience that we can all trust and not need to think about as we walk in and out of a store.”
‘The hardest problem to solve’
At one point Amazon saw Just Walk Out becoming a core part of the experience of shopping in its physical stores. The company in 2018 planned to open as many as 3,000 Amazon Go stores within a few years, Bloomberg reported at the time, citing people familiar with the plans.
Bezos had assigned top talent from across the company, including a longtime Amazon executive who built the original Kindle e-reader, to work on cashierless checkout. The technology was considered a key ingredient in Amazon’s long-running pursuit to become a giant in the $1.6 trillion U.S. grocery market.
When Amazon debuted Just Walk Out in January 2018, it was a “quake moment” for the industry, causing Walmart and “almost every other retailer” to leap into action and consider developing their own vision-based checkout systems, said Berke, who previously led Walmart’s e-commerce business in China.
Amazon and other retailers soon learned that automating the checkout process is “the hardest problem to solve,” Berke said. Cashierless checkout systems require a hefty upfront investment to blanket a store with overhead cameras and hire staff to label and review shopping data.
“It meant a store had to dramatically increase its sales in order to pay off that investment,” Berke said.
Walmart teams found as part of a cost analysis in early 2019 that it would run a retailer between $10 million and $15 million to create a similar computer vision-based checkout system for a 40,000 square foot supermarket, Berke said.
Just Walk Out became an expensive project for Amazon, too. In 2019 and 2020, the company shelled out roughly $1 billion per year, including research and development costs and capital expenditures, to “learn and scale” the technology, Berke said. He said those figures are based on discussions with a former Just Walk Out executive who left Amazon to join Walmart.Amazon didn’t provide a comment on the figures.
Many retailers have since moved on from computer vision in favor of simpler methods like mobile checkout through an app, Berke said.
While it’s no longer featuring Just Walk Out as prominently in its own stores, Amazon says it has inked deals with a growing list of customers. More than 200 third-party stores have paid Amazon to install the cashierless system. The company expects to double the number of third-party Just Walk Out stores this year, Jon Jenkins, who previously served as vice president of Amazon’s Just Walk Out technology, said in a recent interview. Jenkins departed Amazon in late September to become technology chief of electric bike and scooter startup Lime, according to his LinkedIn page.

Jenkins disputed characterizations that Amazon’s phasing out of Just Walk Out from its own supermarkets represents a setback or a sign of the technology’s demise. He said Amazon proved through tests in its own grocery stores that the technology is “incredibly capable,” noting it deployed the system in large supermarkets with “600 people in the store at the same time.”
Other startups such as AiFi and Grabango have developed autonomous systems for supermarkets, convenience stores and other retailers, but widespread adoption has been slow, as the technology remains costly and challenging to operate in large store formats.
Inside the lab
Amazon is still fine-tuning its Just Walk Out technology.
In August, CNBC got the first on-camera look at a mock convenience store where Amazon tests the system before deploying it in third party retailers and its own stores.
The testing lab, which it calls “beverage base camp,” is located in Amazon’s Seattle headquarters. It has faux gates that mimic the experience of scanning your smartphone or credit card to enter a Just Walk Out store. The walls are lined with shelves of typical grab-and-go products like Milky Way bars, pita chips and gum, and there are coolers stocked with Coke cans and other beverages.
Amazon sets up Just Walk Out stores by first creating a 3D scan using LiDAR machines or iPads that help it determine where to place cameras so they have the clearest view.
“The goal is to have the fewest number of cameras possible, so we optimize the camera placement so that we can get enough coverage on each fixture to see what is happening in the store,” Jenkins said.
The system determines what shoppers purchased using several inputs, including the 3D scans, a catalog of product images, the video footage, and weight sensors on the shelves. Amazon in July updated the AI system behind its Just Walk Out technology to handle all the inputs in a store simultaneously.
The new “multi-modal” system can generate receipts faster by more accurately predicting which items shoppers have picked up and put back on shelves. The company said these changes should make it “faster, easier to deploy and more efficient” for retailers who install the system in their stores.
Amazon’s “primary focus” is selling the technology to third-party businesses and deploying it in small to medium-sized store formats, where the system “tends to generate a little better [return on investment],” Jenkins said. Earlier this year, Amazon also began selling its connected grocery carts to third parties.
Amazon in September announced several new third-party Just Walk Out stores at universities and sports stadiums.
CNBC
At one Just Walk Out store, inside Seattle’s Lumen Field, home to the NFL’s Seahawks, the company said it boosted sales by 112% last season, with 85% more transactions during the course of a game.
“It was awesome that we had our own stores as the laboratory to sort of build and launch this,” Jenkins said. “But over time, like many things at Amazon, the success of this project and the product will depend on third parties adopting the technology. There will always be more third-party stores in the world than there will be first-party stores.”
Amazon has used a similar playbook in in the past. Amazon Web Services, the company’s wildly successful cloud-computing unit, originated from the company’s need for IT infrastructure to support its fast-growing online retail business. And in recent years, Amazon has leveraged its logistics and fulfillment network to provide services for third parties.
With Just Walk Out, Amazon faces the challenge of convincing retailers that they can trust one of their biggest competitors with handling valuable shopper data.
In 2022, Amazon moved the team behind Just Walk Out from its retail organization to AWS. It marked one of the clearest signals yet that Amazon is serious about selling the technology to other retailers, and could help ease some fears among rivals.
“They’re clearly in sales mode,” said Sucharita Kodali, retail analyst at Forrester Research, in an interview.
Kodali said Amazon still has a “long way to go” before the technology is ubiquitous. Getting there will require patience from Amazon investors and data that shows both retailers and shoppers are embracing the technology.
“There’s almost a viral effect that will occur over time,” she said. “It’s just going to take a long time because you’ve got to cycle through everybody in America having this experience, and for the most part, it’s just Amazon fighting this fight right now.”
Meta CEO Mark Zuckerberg looks on before the luncheon on the inauguration day of U.S. President Donald Trump’s second Presidential term in Washington, U.S., Jan. 20, 2025.

Mark Zuckerberg’s plan is to make Meta the market leader in artificial intelligence. Investors will want to know how President Donald Trump’s tariffs-heavy trade policies will impact that strategy.
Those answers could start to come as soon as this week as Meta’s AI strategy takes center stage when the company hosts its first Llama-branded conference for AI developers on Tuesday then reports its latest quarterly earnings the next day.
Already, tech companies are starting to talk about the potential impact they’re bracing for as a result of the Trump tariffs.
Intel Chief Financial Officer David Zinsner said Thursday during the chip giant’s first-quarter earnings call that U.S. trade policies “have increased the chance of an economic slowdown, with the probability of a recession growing.” Meanwhile, Google CFO Anat Ashkenazi said that day during a first-quarter earnings call that the tech giant remains committed to its $75 billion investment in capital expenditures, or capex, this year, but also acknowledged that the “timing of deliveries and construction schedules” could cause some quarter-to-quarter spending fluctuation.
For now, analysts expect Meta to follow Alphabet’s lead and remain firm in its plan to spend as much as $65 billion in capex for AI infrastructure this year when it reports earnings Wednesday. Some analysts believe Meta could even raise the figure because AI is a core priority for the company.
“We do not expect META to cut its CapX guidance of $60B-$65B in 2025, for its GenAI infrastructure, because they see this as an important 10-year investment, we believe,” Needham analysts wrote in a research note published Wednesday. “However, tariffs add risks of upward cost revisions.”
Investors will also be monitoring Meta’s LlamaCon event at its Menlo Park, California, headquarters for any signs that its AI investments are having an immediate business impact. This will be the first time Meta hosts a developer conference specifically for its Llama family of AI models.
“Investors want to see ROI on all these AI investments, and while Meta has shown clear benefits from leveraging AI to improve its products and drive faster revenue growth, it’s been hard to quantify those benefits,” Truist Securities analyst Youssef Squali told CNBC.
Meta in April released a couple of its new Llama 4 models, which Meta Chief Product Officer Chris Cox previously said can help power so-called AI agents that can perform tasks for users via web browsers and other online interfaces.
It’s critical that Meta keep improving Llama to create a major business involving AI agents that companies can use to interact with their customers within apps like Facebook and WhatsApp, William Blair research analyst Ralph Schackart said.
“Meta has an early mover advantage at scale in a multi-trillion dollar market,” Schackart said in an email. “We believe Meta is very well positioned to leverage its billions of global users across multiple platforms.”
Meta is unlikely to curb its Llama investment any time soon, but should eventually consider doing so if it fails to generates enough money to justify its costs, said Ken Gawrelski, a Wells Fargo managing director of equity research.
“We do believe that over time Meta needs to continue to evaluate whether Llama needs to be competitive with the leading-edge models,” Gawrelski said. “This is a very expensive proposition and thus far, unlike Google, Meta does not directly monetize its model in any material way.”

Meta AI and the consumer
Analysts are also following the Meta AI digital assistant. That’s because the ChatGPT rival represents the second pillar of Zuckerberg‘s AI strategy.
Zuckerberg in January said he believes 2025 “is going to be the year when a highly intelligent and personalized AI assistant reaches more than 1 billion people, and I expect Meta AI to be that leading AI assistant.”
In February, CNBC reported that Meta was planning to debut a standalone Meta AI app during the second quarter and test a paid subscription service, in which users could pay monthly fees to access more powerful versions like users can with ChatGPT.
Although Meta’s enormous user base across its family of apps gives Meta AI an advantage over rivals like ChatGPT in terms of reach, they may not interact with Meta AI in the same way they do with rival chat apps, said Cantor Fitzgerald analyst Deepak Mathivanan.
Gawrelski said that people may not want to use Meta AI within Facebook and Instagram if all they want to do is passively watch the short videos that Meta algorithmically recommends to their feeds.
“This is why a separate Meta AI, where Meta could clearly articulate its use case and value proposition, could be helpful,” Gawrelski said.
A standalone Meta AI app could help the company better market the digital assistant and distinguish it from rivals, said Debra Aho Williamson, founder and chief analyst for Sonata Insights.
“ChatGPT has such wide brand awareness, that it’s become a moat that is soon going to be very hard to overcome,” Williamson said.
TikTok’s grip on the short-form video market is tightening, and the world’s biggest tech platforms are racing to catch up.
Since launching globally in 2016, ByteDance-owned TikTok has amassed over 1.12 billion monthly active users worldwide, according to Backlinko. American users spend an average of 108 minutes per day on the app, according to Apptoptia.
TikTok’s success has reshaped the social media landscape, forcing competitors like Meta and Google to pivot their strategies around short-form video. But so far, experts say that none have matched TikTok’s algorithmic precision.
“It is the center of the internet for young people,” said Jasmine Enberg, vice president and principal analyst at Emarketer. “It’s where they go for entertainment, news, trends, even shopping. TikTok sets the tone for everyone else.”
Platforms like Meta‘s Instagram Reels and Google’s YouTube Shorts have expanded aggressively, launching new features, creator tools and even considering separate apps just to compete. Microsoft-owned LinkedIn, traditionally a professional networking site, is the latest to experiment with TikTok-style feeds. But with TikTok continuing to evolve, adding features like e-commerce integrations and longer videos, the question remains whether rivals can keep up.
“I’m scrolling every single day. I doom scroll all the time,” said TikTok content creator Alyssa McKay.
But there may a dark side to this growth.
As short-form content consumption soars, experts warn about shrinking attention spans and rising mental-health concerns, particularly among younger users. Researchers like Dr. Yann Poncin, associate professor at the Child Study Center at Yale University, point to disrupted sleep patterns and increased anxiety levels tied to endless scrolling habits.
“Infinite scrolling and short-form video are designed to capture your attention in short bursts,” Dr. Poncin said. “In the past, entertainment was about taking you on a journey through a show or story. Now, it’s about locking you in for just a few seconds, just enough to feed you the next thing the algorithm knows you’ll like.”
Despite sky-high engagement, monetizing short videos remains an uphill battle. Unlike long-form YouTube content, where ads can be inserted throughout, short clips offer limited space for advertisers. Creators, too, are feeling the squeeze.
“It’s never been easier to go viral,” said Enberg. “But it’s never been harder to turn that virality into a sustainable business.”
Last year, TikTok generated an estimated $23.6 billion in ad revenues, according to Oberlo, but even with this growth, many creators still make just a few dollars per million views. YouTube Shorts pays roughly four cents per 1,000 views, which is less than its long-form counterpart. Meanwhile, Instagram has leaned into brand partnerships and emerging tools like “Trial Reels,” which allow creators to experiment with content by initially sharing videos only with non-followers, giving them a low-risk way to test new formats or ideas before deciding whether to share with their full audience. But Meta told CNBC that monetizing Reels remains a work in progress.
While lawmakers scrutinize TikTok’s Chinese ownership and explore potential bans, competitors see a window of opportunity. Meta and YouTube are poised to capture up to 50% of reallocated ad dollars if TikTok faces restrictions in the U.S., according to eMarketer.

Elon Musk‘s xAI Holdings is in discussions with investors to raise about $20 billion, Bloomberg News reported Friday, citing people familiar with the matter.
The funding would value the company at over $120 billion, according to the report.
Musk was looking to assign “proper value” to xAI, sources told CNBC’s David Faber earlier this month. The remarks were made during a call with xAI investors, sources familiar with the matter told Faber. The Tesla CEO at that time didn’t explicitly mention any upcoming funding round, but the sources suggested xAI was preparing for a substantial capital raise in the near future.
The funding amount could be more than $20 billion as the exact figure had not been decided, the Bloomberg report added.
Artificial intelligence startup xAI didn’t immediately respond to a CNBC request for comment outside of U.S. business hours.
The AI firm last month acquired X in an all-stock deal that valued xAI at $80 billion and the social media platform at $33 billion.
“xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent,” Musk said on X, announcing the deal. “This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.”
