Amazon has discontinued a secretive effort to develop an at-home fertility tracker, according to internal documents and people familiar with the matter.
The company had been working to launch a fertility monitoring device and companion smartphone app for the past four years as part of a project codenamed “Encore,” said the people, who asked not to be named because they weren’t authorized to speak to the press. The team sat within Amazon’s Grand Challenge, also known as its Special Projects division, the sources said.
Last month, Amazon told people working on the tracker that it was disbanding the team. Those being laid off will remain on Amazon’s payroll until Dec. 27, but won’t be expected to work during that time, according to documents reviewed by CNBC.
If staffers don’t secure another job by that date, Amazon will provide them with a “lump sum” severance payment equal to one week of salary for every six months of tenure at the company, the documents said.
Amazon CEO Andy Jassy has been reeling in costs companywide since late 2022, when inflationary pressures and rising interest rates led to a slowdown across the tech and consumer markets. In addition to slashing more than 27,000 jobs, Jassy has shuttered several projects, ranging from a roving sidewalk robot to a telehealth offering and a rapid delivery service.
The wave of frugality marks a distinct departure from the approach taken by Amazon founder Jeff Bezos, Jassy’s predecessor, who was known for greenlighting experimental projects and giving employees extended runway to develop them, even if they burned cash along the way. Grand Challenge was one of the hallmarks of that era.
Bezos launched Grand Challenge in 2014 as a way for Amazon to tinker with riskier projects that may or may not see the light of day. Grand Challenge was the brains behind a pair of connected eyeglasses equipped with Amazon’s Alexa voice assistant and a machine learning tool for analyzing medical records.
On the morning of Oct. 28, employees working on the fertility tracker were told to join a videoconference where a director of the team informed them that the project was ending. The call lasted about two minutes, one of the people said.
A layoff notice viewed by CNBC was signed by Doug Weibel, who took over as the head of Grand Challenge after its founding leader, Babak Parviz, left in 2022 and joined Madrona Venture Group.
Margaret Callahan, an Amazon spokesperson, confirmed the layoffs and the existence of the project in a statement to CNBC. Roughly 100 employees will be laid off, Callahan confirmed.
“Following a recent review, we’ve decided to discontinue this project within Grand Challenge, and we’re working directly with employees whose roles are impacted to support them through the transition and help them find other opportunities within Amazon,” Callahan said.
Predicting fertility with saliva
The project was born out of the company’s 2020 acquisition of Wisconsin-based startup bluDiagnostics, the sources said.
BluDiagnostics was founded in 2015 by Weibel, Katie Brenner and Jodi Schroll, all of whom joined Grand Challenge following the purchase. The startup had developed a thermometer-like device, called FertilityFinder, to help women track their fertility from home by testing their saliva and measuring two key hormones, estradiol and progesterone. The results of the test were viewable through a corresponding app.
Business Insider reported on aspects of the fertility device in 2022, when its codename was Project Tiberius.
The team was working to develop its own saliva collection device and mobile app, which could predict when a user might be in the fertile window. Users could also log their period symptoms, sexual activity and other data to assist with tracking their fertility.There are similar offerings on the market from companies including Inne, Oova, Ava and Mira, along with fertility and ovulation tracking apps like Flo, Clue and Max Levchin’s Glow.
Amazon initially aimed to release the product this year, but the timing was pushed out after the team encountered technical issues with the device, one of the people said. It was a costly endeavor and required significant upfront investments for lab research and development, in addition to the high salaries for scientists and engineers, the sources said, adding that the team’s weekly overhead was roughly $1.5 million. Amazon didn’t comment on the figure.
Only one project now remains active within Grand Challenge. Its focus is on health tech, the people 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.”

Alphabet‘s stock gained 3% Friday after signaling strong growth in its search and advertising businesses amid a competitive artificial intelligence environment and uncertain macro backdrop.
“GOOGL‘s pace of GenAI product roll-out is accelerating with multiple encouraging signals,” wrote Morgan Stanley‘s Brian Nowak. “Macro uncertainty still exists but we remain [overweight] given GOOGL’s still strong relative position and improving pace of GenAI enabled product roll-out.”
The search giant posted earnings of $2.81 per share on $90.23 billion in revenues. That topped the $89.12 billion in sales and $2.01 in EPS expected by LSEG analysts. Revenues grew 12% year-over-year and ahead of the 10% anticipated by Wall Street.
Net income rose 46% to $34.54 billion, or $2.81 per share. That’s up from $23.66 billion, or $1.89 per share, in the year-ago period. Alphabet said the figure included $8 billion in unrealized gains on its nonmarketable equity securities connected to its investment in a private company.
Adjusted earnings, excluding that gain, were $2.27 per share, according to LSEG, and topped analyst expectations.

Alphabet shares have pulled back about 16% this year as it battles volatility spurred by mounting trade war fears and worries that President Donald Trump‘s tariffs could crush the global economy. That would make it more difficult for Alphabet to potentially acquire infrastructure for data centers powering AI models as it faces off against competitors such as OpenAI and Anthropic to develop largely language models.
During Thursday’s call with investors, Alphabet suggested that it’s too soon to tally the total impact of tariffs. However, Google’s business chief Philipp Schindler said that ending the de minimis trade exemption in May, which created a loophole benefitting many Chinese e-commerce retailers, could create a “slight headwind” for the company’s ads business, specifically in the Asia-Pacific region. The loophole allows shipments under $800 to come into the U.S. duty-free.
Despite this backdrop, Alphabet showed steady growth in its advertising and search business, reporting $66.89 billion in revenues for its advertising unit. That reflected 8.5% growth from the year-ago period. The company reported $8.93 billion in advertising revenue for its YouTube business, shy of an $8.97 billion estimate from StreetAccount.
Alphabet’s “Search and other” unit rose 9.8% to $50.7 billion, up from $46.16 billion last year. The company said that its AI Overviews tool used in its Google search results page has accumulated 1.5 billion monthly users from a billion in October.
Bank of America analyst Justin Post said that Wall Street is underestimating the upside potential and “monetization ramp” from this tool and cloud demand fueled by AI.
“The strong 1Q search performance, along with constructive comments on Gemini [large language model] performance and [AI Overviews] adoption could help alleviate some investor concerns on AI competition,” Post wrote in a note.
