Why Chinese AI company DeepSeek is spooking investors on U.S. tech
Major U.S. tech stocks, including Nvidia, Oracle and Broadcom, plummeted Monday after Chinese artificial intelligence startup DeepSeek unveiled a new system that it says can compete against OpenAI’s ChatGPT model at a much lower cost.
The stock of chipmakers Nvidia and Broadcom plunged about 17%, while the stock price for Oracle declined 14%. The tech sell-off brought the broader stock market down with it. The Standard & Poor’s 500 index dropped 1.5% and the tech-focused Nasdaq 100 sank 3%.
“Companies are worried that DeepSeek will crush the profit capabilities of U.S. AI giants,” said Ray Wang, chief executive of Constellation Research, a research and advisory firm in Silicon Valley.
Despite its market-moving clout, DeepSeek is hardly a household name in the U.S. Here’s a primer.
What is DeepSeek and who is behind it?
DeepSeek is a Chinese startup that develops open-source AI models, similar to ChatGPT, which helped bring generative artificial intelligence to the mainstream.
Its mobile app surged to the top of Apple’s download charts in the U.S. after its release in early January. The DeepSeek mobile app was downloaded 1.6 million times by Jan. 25 and ranked No. 1 in iPhone app stores in Australia, Canada, China, Singapore, the U.S. and the United Kingdom, according to data from market tracker App Figures.
The app distinguishes itself from other chatbots such as OpenAI’s ChatGPT by articulating its reasoning before delivering a response to a prompt. The company claims its latest model, DeepSeek-R1, offers performance on par with OpenAI’s latest system, and lets individuals interested in developing chatbots on the technology build on its software.
DeepSeek caught the attention of Silicon Valley by saying it could compete with OpenAI at lower costs. DeepSeek said it needed only roughly 2,000 specialized computer chips from Nvidia to train its chatbots, according to the New York Times. U.S. companies, by comparison, use supercomputers with as many as 16,000 chips and sometimes more, the newspaper reported.
Hedge fund manager Liang Wenfeng founded DeepSeek in 2023. Liang co-founded the hedge fund High-Flyer with college friends in 2015 shortly after graduating, according to the Wall Street Journal.
Why did U.S. tech stocks take such a hit?
On Monday, Nvidia lost roughly $600 billion in market value, the biggest single day drop for a company in U.S. history, according to CNBC.
Investors worry that if DeepSeek can build a model that requires fewer chips, that would reduce the demand for the types of semiconductors Nvidia and other firms supply. It also could reduce the competitive edge of U.S. tech giants that have invested billions in AI technology.
Washington has banned the export of high-end technologies such as graphics processing unit semiconductors (or GPUs, which are crucial for AI technology) to China, in a bid to stall the country’s advances. But DeepSeek’s progress suggests Chinese AI engineers have worked their way around the restrictions, focusing on greater efficiency with limited resources.
“The DeepSeek model is … very impressive, especially since DeepSeek had to navigate strict chip restrictions from the U.S.,” wrote Wedbush Securities analyst Daniel Ives in a Monday research note. “It remains to be seen if DeepSeek found a way to work around these chip restrictions rules and what chips they ultimately used, as there will be many skeptics around this issue given the information is coming from China.”
How much of a threat does China pose to U.S. dominance in the AI market?
The U.S. is still a major leader in the artificial intelligence sector, capturing 68% of the global venture capital funding in AI companies in the third quarter of last year, according to CB Insights. The Silicon Valley geographic area took up roughly half that amount.
Some of the leaders in the space including San Francisco-based startups such as ChatGPT maker OpenAI and Anthropic, as well as blue chip tech giants including Google’s parent company, Alphabet, and Meta. Alphabet’s stock fell 4% on Monday, while Meta’s rose slightly.
Some analysts were skeptical about the veracity of DeepSeek and what the model can actually accomplish. After all, other companies probably would try to match DeepSeek’s savings.
“What DeepSeek showed is that there are lots of efficiency gains that every AI company can achieve,” Wang said. “However, we haven’t verified if this is true or not and what problems are being solved.”
He said China is a “strong competitor,” but “the psychological operations warfare as we saw today is more powerful than what they really can deliver.”
How will the Trump administration respond?
Trump has emphasized the importance of America being a leader in AI technology and innovation.
After Trump started his second term as president, he rescinded an executive order signed by President Biden in 2023 that required AI companies to share their safety test results with the U.S. government.
Although some people in the tech industry applauded Biden’s executive order as a way of establishing guardrails and guidelines for AI companies, others expressed concern that it could stifle innovation. Trump while a candidate warned that Biden’s policies, including that executive order, weren’t working.
On Monday, David Sacks, Trump’s White House AI and crypto czar, said DeepSeek has shown the AI race will be very competitive.
“President Trump was right to rescind the Biden EO, which hamstrung American AI companies without asking whether China would do the same. (Obviously not.),” Sacks wrote Monday on social media platform X. “I’m confident in the U.S. but we can’t be complacent.”
Trump last week announced that OpenAI, Oracle and Softbank are committing $100 billion to an initiative called the Stargate project, with plans to invest $500 billion in AI infrastructure over the next four years. Trump said it would help create more than 100,000 U.S. jobs.

California gas is pricey already. The Iran war could cost you even more
The U.S. attack on Iran is expected to have an unwelcome impact on California drivers — a jump in gas prices that could be felt at the pump in a week or two.
The outbreak of war in the Middle East, which virtually closed a key Persian Gulf shipping lane, spiked the price of a barrel of Brent crude oil by as much as $10, with prices rising as high as $82.37 on Monday before settling down.
The price of the international standard dictates what motorists pay for gas globally, including in California, with every dollar increase translating to 2.5 cents at the pump, said Severin Borenstein, faculty director of the Energy Institute at UC Berkeley’s Haas School of Business.
That would mean drivers could pay at least 20 cents more per gallon, though how much damage the conflict will do to wallets remains to be seen.
“The real issue though is the oil markets are just guessing right now at what is going to happen. It’s a time of extreme volatility,” Borenstein said. “We don’t know whether the war will widen or end quickly, and all of those things will drive the price of crude.”
President Trump has lauded the reduction of nationwide gas prices as a validation of his economic agenda despite worries about a weak job market and concerns of persistent inflation.
The upheaval in the Middle East could be more acutely felt in the state.
Californians already pay far more for gas than the rest of the country, with the average cost of a gallon of regular at $4.66, up 3 cents from a week ago and 30 cents from a month ago, according to AAA. The current nationwide average is about $3 per gallon.
The disruption in international crude markets also comes as refiners are switching to producing California’s summer-blend gas, which is less volatile during the state’s hot summers. The switch can drive up the price of a gallon of gas at least 15 cents.
The prices in California are largely driven by higher taxes and a cleaner, less polluting blend required year-round by regulators to combat pollution — and it’s long been a hot-button issue.
The politics were only exacerbated by recent refinery closures, including the Phillips 66 refinery in Wilmington in October and the idling and planned closure of the Valero refinery in Benicia, Calif., which reduced refining capacity in the state by about 18%.
California also has seen a steady reduction in its crude oil production, making it more reliant on international imports of oil and gasoline.
In 2024, only 23.3% of the crude oil refined in the state was pumped in California, with 13% from Alaska and 63% from elsewhere in the world, including about 30% from the Middle East, said Jim Stanley, a spokesperson for the Western States Petroleum Assn.
“We could see a supply crunch and real price volatility” if the Middle East supply is interrupted, he said.
The Strait of Hormuz in the Persian Gulf, through which about 20% of the world’s oil passes, was virtually closed Monday, according to reports. Though it produces only about 3% of global oil, Iran has considerable sway over energy markets because it controls the strait.
Also, in response to the U.S. attack, Iran has fired a barrage of missiles at neighboring Persian Gulf states. Saudi Arabia said it intercepted Iranian drones targeting one of its refinery complexes.
California Republicans and the California Fuels & Convenience Alliance, a trade group representing fuel marketers, gas station owners and others, have blamed Gov. Gavin Newsom’s policies for driving up the price of gas.
A landmark climate change law calls for California to become carbon neutral by 2045, and Newsom told regulators in 2021 to stop issuing fracking permits and to phase out oil extraction by 2045. He also signed a bill allowing local governments to block construction of oil and gas wells.
However, last year Newsom changed his stance and signed a bill that will allow up to 2,000 new oil wells per year through 2036 in Kern County despite legal challenges by environmental groups. The county produces about three-fourths of the state’s crude oil.
Borenstein said he didn’t expect that the new state oil production would do much to lower gas prices because it is only marginally cheaper than oil imported by ocean tankers.
Stanley said the aim of the law was to support the Kern County oil industry, which was facing pipeline closures without additional supplies to ship to state refineries.
Statewide, the industry supports more than 535,000 jobs, $166 billion in economic activity and $48 billion in local and state taxes, according to a report last year by the Los Angeles County Economic Development Corp.

Block to cut more than 4,000 jobs amid AI disruption of the workplace
Fintech company Block said Thursday that it’s cutting more than 4,000 workers or nearly half of its workforce as artificial intelligence disrupts the way people work.
The Oakland parent company of payment services Square and Cash App saw its stock surge by more than 23% in after-hours trading after making the layoff announcement.
Jack Dorsey, the co-founder and head of Block, said in a post on social media site X that the company didn’t make the decision because the company is in financial trouble.
“We’re already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company,” he said.
Block is the latest tech company to announce massive cuts as employers push workers to use more AI tools to do more with fewer people. Amazon in January said it was laying off 16,000 people as part of effort to remove layers within the company.
Block has laid off workers in previous years. In 2025, Block said it planned to slash 931 jobs, or 8% of its workforce, citing performance and strategic issues but Dorsey said at the time that the company wasn’t trying to replace workers with AI.
As tech companies embrace AI tools that can code, generate text and do other tasks, worker anxiety about whether their jobs will be automated have heightened.
In his note to employees Dorsey said that he was weighing whether to make cuts gradually throughout months or years but chose to act immediately.
“Repeated rounds of cuts are destructive to morale, to focus, and to the trust that customers and shareholders place in our ability to lead,” he told workers. “I’d rather take a hard, clear action now and build from a position we believe in than manage a slow reduction of people toward the same outcome.”
Dorsey is also the co-founder of Twitter, which was later renamed to X after billionaire Elon Musk purchased the company in 2022.
As of December, Block had 10,205 full-time employees globally, according to the company’s annual report. The company said it plans to reduce its workforce by the end of the second quarter of fiscal year 2026.
The company’s gross profit in 2025 reached more than $10 billion, up 17% compared to the previous year.
Dorsey said he plans to address employees in a live video session and noted that their emails and Slack will remain open until Thursday evening so they can say goodbye to colleagues.
“I know doing it this way might feel awkward,” he said. “I’d rather it feel awkward and human than efficient and cold.”

WGA cancels Los Angeles awards show amid labor strike
The Writers Guild of America West has canceled its awards ceremony scheduled to take place March 8 as its staff union members continue to strike, demanding higher pay and protections against artificial intelligence.
In a letter sent to members on Sunday, WGA West’s board of directors, including President Michele Mulroney, wrote, “The non-supervisory staff of the WGAW are currently on strike and the Guild would not ask our members or guests to cross a picket line to attend the awards show. The WGAW staff have a right to strike and our exceptional nominees and honorees deserve an uncomplicated celebration of their achievements.”
The New York ceremony, scheduled on the same day, is expected go forward while an alternative celebration for Los Angeles-based nominees will take place at a later date, according to the letter.
Comedian and actor Atsuko Okatsuka was set to host the L.A. show, while filmmaker James Cameron was to receive the WGA West Laurel Award.
WGA union staffers have been striking outside the guild’s Los Angeles headquarters on Fairfax Avenue since Feb. 17. The union alleged that management did not intend to reach an agreement on the pending contract. Further, it claimed that guild management had “surveilled workers for union activity, terminated union supporters, and engaged in bad faith surface bargaining.”
On Tuesday, the labor organization said that management had raised the specter of canceling the ceremony during a call about contraction negotiations.
“Make no mistake: this is an attempt by WGAW management to drive a wedge between WGSU and WGA membership when we should be building unity ahead of MBA [Minimum Basic Agreement] negotiations with the AMPTP [Alliance of Motion Picture and Television Producers],” wrote the staff union. “We urge Guild management to end this strike now,” the union wrote on Instagram.
The union, made up of more than 100 employees who work in areas including legal, communications and residuals, was formed last spring and first authorized a strike in January with 82% of its members. Contract negotiations, which began in September, have focused on the use of artificial intelligence, pay raises and “basic protections” including grievance procedures.
The WGA has said that it offered “comprehensive proposals with numerous union protections and improvements to compensation and benefits.”
The ceremony’s cancellation, coming just weeks before the Academy Awards, casts a shadow over the upcoming contraction negotiations between the WGA and the Alliance of Motion Picture and Television Producers, which represents the studios and streamers.
In 2023, the WGA went on a strike lasting 148 days, the second-longest strike in the union’s history.
