Atop a newly-completed, 3.5-million-square-foot building that stands on 1,100 acres in the Arizona desert north of Phoenix is a giant logo of a microchip wafer and the letters TSMC.
CNBC first visited the fab in 2021, not long after TSMC broke ground. TSMC initially announced the plant would cost $12 billion and pump out 5-nanometer chips by the end of 2024. Three years later, that price tag has soared to $20 billion and full production is delayed until 2025.
Instead, the fab is in pilot production, making sample wafers and sending them to customers for verification. TSMC has committed to building two more fabs on the site by the end of the decade, for a total investment of $65 billion.
The project is “dang near back on the original schedule,” TSMC Chariman Rick Cassidy told CNBC during an exclusive first look at the completed fab in November.
“When we came to the U.S., we knew we were going to go through a learning process,” Cassidy said. “Whether it was permitting, learning how to work with the trades, learning how to work with the unions, local labor laws. Lots of learnings that went on. Now we’ve overcome those.”

With the help of some 2,000 employees, the fab is set to make more advanced chips than originally planned. It will produce 4-nanometer chips, at a rate of 20,000 wafers per month, TSMC said.
“We’ve seen TSMC be able to kind of name its price, and everyone’s going to pay it because right now it’s the dependability and the quality that is needed,” said Daniel Newman, CEO of The Futurum Group.
‘On par with our Taiwan compatriots’
The fab’s yields are anticipated to be “right on par with our Taiwanese compatriots,” Cassidy said. Still, some 92% of the world’s most advanced chips are currently made by TSMC’s Taiwan fabs, so the U.S. is far from self-reliant.
“It’s difficult or impossible for the U.S. or any country to be fully self-sufficient in everything that they need to build semiconductors,” said Stacy Rasgon of Bernstein Research. “That’s a pipe dream.”
Despite being the birthplace of microchips in the 1950s and remaining a top chip design hub, the U.S. now manufactures only 10% of the world’s chips and none of the most advanced ones. When supply chain chaos collided with booming demand for consumer electronics during the pandemic, the resulting chip shortage exposed the big risks of relying on outsiders for such a critical technology.
In the event of aggression between China and Taiwan, an earthquake or some other event that impacts Taiwan for a period of time, “the entire market, the entire world could suffer from lack of availability of leading edge nodes,” Newman said.

Other fears surfaced when President-elect Donald Trump expressed opposition to the $52 billion CHIPS Act in October during his campaign. Weeks later, the U.S. Commerce Department finalized TSMC’s allotted $6.6 billion from the bipartisan bill.
“Repealing the CHIPS Act would make Americans less safe,” Commerce Secretary Gina Raimondo told CNBC in an interview, adding that she doesn’t think the incoming administration would repeal it.
“I just don’t think they’ll do that,” Raimondo said.
Talks with TSMC about bringing advanced chip production to the U.S. began in 2018, during Trump’s first term.
“I set up a phone call between the chairman of TSMC and the head of Apple,” said Wilbur Ross, who was commerce secretary at the time. “Apple became very strongly supportive of the idea of TSMC coming.”
Rose Castanares, a 26-year company veteran and now president of TSMC Arizona, was also involved with the early conversations. Customers “wanted supply resilience,” Castanares said.
Relying on chips from Asia has also complicated the U.S. drive for technological dominance. That’s why President Joe Biden hit the chip industry with a complex web of export controls meant to keep China from pulling ahead with advanced tech.
In October, some TSMC chips were spotted in Huawei devices, despite bans on selling to the Chinese company.
“This problem is as old as time,” Newman said. “There’s a lot of complex rerouting of goods to get gray market to different countries that have limited access to leading edge or the most advanced technology.”

Workers, water and power
Nearby in Chandler, Arizona, Intel is also building two huge fabs.
The U.S. company has a far different business model, designing and manufacturing its own chips, while TSMC only makes chips for others. The relationship between the two companies is solid, Cassidy said.
“We meet with [Intel] weekly and the feedback is we’re helping them increase their ranks,” Cassidy said. “We’re helping them train on the most advanced stuff, so I think they’re pretty happy with what we’re doing.”
Both companies have delayed the timelines for full production at their new Arizona fabs. But where TSMC has remained the uncontested leader in advanced chips, Intel has stumbled time and again.
The two will also be competing for a scarce resource in the U.S. chip industry: workers.
“When we finished the construction of this fab, it was really the first advanced manufacturing fab that had been built in the United States for at least 10 years. Semiconductors is a very, very tough technology,” TSMC’s Castanares said. “The experience is just not here in the United States.”
At the beginning of the project, TSMC sent some 600 engineers to train in Taiwan. Process integration engineer Jeff Patz spent 18 months there starting in 2021.
“The purpose was to go and actually make things, right? And learn how they’re made,” Patz said. “You have to have a kitchen to cook.”
TSMC has also brought experts over from Taiwan on 3-year temporary assignments. TSMC plans to hire at least 6,000 workers by the time all three fabs are completed.
“For engineers, we are actively recruiting at universities in Arizona and all across the U.S.,” Castanares said. Arizona State University “even has what they call a TSMC day.”
Water is another scarce resource needed in abundance.
With Taiwan recently facing its worst drought in nearly a century, TSMC is no stranger to recycling the massive amount of water it needs to make chips. TSMC will take 4.7 million gallons of water daily to run the first Arizona fab, but it will bring that demand down to 1 million gallons a day, in part by recycling some 65% of that, the company said.
It also takes a massive amount of power to make chips.
TSMC built solar on site, but it’s not nearly enough to cover the 2.85 gigawatt-hours per day needed to run the first fab. That’s equivalent to the power used by roughly 100,000 U.S. homes. TSMC said it’s purchasing renewable energy credits to offset that. But amid the AI-fueled data center boom, Arizona’s largest utility warned that it could run out of transmission capacity before the end of the decade.
That’s also when TSMC plans to start production at its third Arizona fab, which Cassidy said is “probably going to be 2 nanometer and more advanced.”
TSMC is also broadening its global footprint. It opened its first fab in Japan in February and broke ground on an $11 billion fab in Germany in August.
Within the U.S., Cassidy said TSMC is also likely to keep expanding.
“There’s room for lots of fabs,” Cassidy 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.
