The feud between Anthropic and the Department of Defense ratcheted up on Friday after President Trump ordered all government agencies to immediately cease using the artificial intelligence startup's technology.

"We don’t need it, we don’t want it, and will not do business with them again!" Trump posted on Truth Social.

The president weighed in on the standoff after Anthropic CEO, Dario Amodei, said on Thursday that the company would cut ties with the government rather than lift restrictions on its AI model's usage.

"We cannot in good conscience accede to their request," Amodei wrote in response to the Defense Department's demands to use the AI model for "all lawful purposes." The government has given Anthropic until 5:01 p.m. on Friday to answer its request to use models as it sees fit.

OpenAI (OPAI.PVT) also joined the fray, with the Wall Street Journal reporting that CEO Sam Altman told his staff that the ChatGPT maker was working on a deal to help resolve the feud between the startup's rival Anthropic (ANTH.PVT) and the Department of Defense. “We would like to try to help de-escalate things,” Altman wrote in a note to employees.

OpenAI (OPAI.PVT) also announced on Friday that it raised $110 billion in a record-breaking funding round and counted SoftBank (SFTBY), Nvidia (NVDA), and Amazon (AMZN) among its backers. The startup's latest fundraising round values the company at $730 billion pre-money.

President Trump on Friday ordered the federal government to cease all use of Anthropic's technology, amid the ongoing standoff between the AI company and the Department of Defense (DOD).

In a post on Truth Social, Trump wrote, \\"I am directing EVERY Federal Agency in the United States Government to IMMEDIATELY CEASE all use of Anthropic’s technology. We don’t need it, we don’t want it, and will not do business with them again!\\"

THE UNITED STATES OF AMERICA WILL NEVER ALLOW A RADICAL LEFT, WOKE COMPANY TO DICTATE HOW OUR GREAT MILITARY FIGHTS AND WINS WARS! That decision belongs to YOUR COMMANDER-IN-CHIEF, and the tremendous leaders I appoint to run our Military.

The Leftwing nut jobs at Anthropic…

Anthropic is seeking to put guardrails in place that would prevent the DOD from using its models for the mass surveillance of Americans or to develop fully autonomous weapons. The DOD has pushed back, saying it should have access to Anthropic's technology for all lawful purposes.

In his post, Trump said there will be a six-month phase-down period for agencies such as the DOD that use Anthropic's products. He also threatened that if the company doesn't \\"get their act together, and be helpful\\" during the phase-out period, he will \\"use the Full Power of the Presidency to make them comply, with major civil and criminal consequences to follow.\\"

Anthropic (ANTH.PVT) CEO Dario Amodei issued a statement Thursday evening, saying his company won't submit to the Department of Defense’s demands that it be allowed to use its AI technology as it sees fit, within the law.

The Defense Department and Secretary of Defense Pete Hegseth have threatened to force Anthropic to give the Pentagon full use of its models under the Defense Production Act — or, conversely, declare it a supply chain threat and force other Pentagon vendors who work with the AI company to stop using its software.

“These threats do not change our position: we cannot in good conscience accede to their request,” Amodei said in his statement.

Anthropic and the Pentagon have been in an ongoing standoff about how the DOD will use its Claude AI. The company says that while it already works with the Defense Department, including within the government's classified networks and by advocating for strong chip export controls to China, it wants assurances that the DOD will not use its models for the mass surveillance of Americans or for fully autonomous weapons.

Earlier Thursday, chief Pentagon spokesman Sean Parnell said the DOD had no desire to surveil Americans or develop fully autonomous weapons.

\\"This is a simple, common-sense request that will prevent Anthropic from jeopardizing critical military operations and potentially putting our warfighters at risk. We will not let ANY company dictate the terms regarding how we make operational decisions. They have until 5:01 PM ET on Friday to decide,\\" Parnell wrote in a post on X.

In a separate statement, an Anthropic spokesperson said the DOD's latest contract language doesn't address the company's concerns.

\\"The contract language we received overnight from the Department of War made virtually no progress on preventing Claude's use for mass surveillance of Americans or in fully autonomous weapons,\\" the spokesperson said.

\\"New language framed as compromise was paired with legalese that would allow those safeguards to be disregarded at will. Despite DOW's recent public statements, these narrow safeguards have been the crux of our negotiations for months.\\"

SpaceX (SPAX.PVT) is looking at confidentially filing paperwork for an initial public offering as early as next month, according to Bloomberg.

The move to file with the SEC in March would keep Elon Musk's rocketry company on track for a June offering, ahead of other potential mega-IPOs this year from frontier AI developers OpenAI (OPAI.PVT) and Anthropic (ANTH.PVT).

After acquiring Musk's xAI company in February, SpaceX is now valued at $1.25 trillion. Through the IPO process, the company may look for a valuation of more than $1.75 trillion. Such an offering would immediately place SpaceX among the \\"Magnificent Seven\\" and other Big Tech giants as among the largest companies in the world.

The SpaceX IPO would raise as much as $50 billion, outstripping Saudi Aramco's record $29 billion IPO, according to Bloomberg.

In December, Bloomberg reported that SpaceX had told employees the company was entering the regulatory \\"quiet period\\" required ahead of a public offering, and that the IPO would be aimed at funding an “insane flight rate” for its developmental Starship rocket, a base on the moon, and data centers in space.

Microsoft (MSFT) and OpenAI (OPAI.PVT) jointly reaffirmed that their partnership hasn't changed despite the ChatGPT maker's new agreement with Amazon (AMZN).

\\"The partnership remains strong and central,\\" a statement on the Microsoft blog read. \\"Microsoft and OpenAI continue to work closely across research, engineering, and product development, building on years of deep collaboration and shared success.\\"

The companies reasserted that their IP relationship, commercial and revenue-sharing relationship, and AGI processes remain unchanged.

Azure remains the exclusive cloud provider for stateless OpenAI APIs, Microsoft said, following Amazon's announcement on Friday that it will be the exclusive third-party cloud distribution provider for OpenAI Frontier.

The clarification was intended to reassure Microsoft shareholders and enterprise customers of the partnership as OpenAI's complicated web of investors and deals expands.

OpenAI is entering the fray. In a note to employees, CEO Sam Altman said the company is working toward establishing a contract with the Department of Defense that would give the DOD access to its AI models, according to The Wall Street Journal.

The catch? Altman says he wants to institute the same guardrails that have put the department and its rival Anthropic at loggerheads: no using models for mass surveillance of Americans and no using them to develop fully autonomous weapons.

The news comes just hours before a 5:01 p.m. ET deadline set by the DOD for Anthropic to agree to allow the Pentagon to use its models as it sees fit or face the consequences. The department has said it will either label Anthropic a supply chain threat, which would force vendors that work with the DOD to stop using its models, or institute the Defense Production Act, which would force Anthropic to give the Pentagon full access to its models.

Thursday evening, Anthropic CEO Dario Amodei wrote in a blog post that while the company is still working to negotiate with the DOD, he and his company \\"cannot in good conscience accede to their request.\\"

OpenAI (OPAI.PVT) said on Friday that it has received $110 billion in new investments, including $30 billion from SoftBank (SFTBY), $30 billion from Nvidia (NVDA), and $50 billion from Amazon (AMZN), to help scale its artificial intelligence products.

As part of the announcement, OpenAI and Amazon announced a strategic partnership to co-create a system for AWS customers to build generative AI applications and agents using OpenAI models. AWS will be the exclusive third-party cloud distribution provider for OpenAI Frontier, Amazon said in a statement.

OpenAI also expanded its partnership with Nvidia, receiving 3 gigawatts of dedicated inference capacity and 2 gigawatts of training on Vera Rubin systems. Nvidia and Amazon stocks fell in premarket trading.

The close of the fundraising round valued OpenAI at $730 billion pre-money, a good step up from the $500 billion valuation reported in October that demonstrates how high expectations have run for the AI startup's technology.

Markets have become jumpy in recent weeks as spending on AI technology has continued to ramp up, companies have entered complex webs of financing with one another, and competition among OpenAI, Anthropic, and Alphabet has increased.

CoreWeave (CRWV), an AI cloud-computing company that counts hyperscalers like Google parent Alphabet (GOOG, GOOGL) and Microsoft (MSFT) as both clients and competitors, saw its shares slump as much as 10% in after-hours trading after the company announced a slight earnings beat but predicted a massive jump in spending for 2026.

On an earnings call with analysts, CEO Michael Intrator said capital expenditures would increase from $15.4 billion in 2025 to at least $30 billion in 2026. The company also said that its net loss in the fourth quarter surged to $284 million from $36 million last year and noted issues with its revenue backlog.

From Reuters:

CoreWeave has positioned itself as a more specialized and cost-effective alternative to the big tech companies, attracting clients ​ranging from ​AI labs to large enterprises.

But it ​still relies heavily on large ‌clients such as Microsoft and OpenAI, which remain critical to its growth trajectory, and faces significant revenue backlog risk.

CoreWeave faces lingering concerns regarding its backlog risk, debt and cost of capital, D.A. Davidson analyst Alexander Platt noted.

Revenue backlog was $66.8 billion as of December 31, CoreWeave said, up from $15.1 ‌billion a year earlier.

CoreWeave has fielded criticism for being part of a web of circular AI funding between companies like Nvidia (NVDA), Microsoft (MSFT), Alphabet (GOOG, GOOGL), and the still-private OpenAI (OPAI.PVT).

Anthropic's deadline to respond to the Pentagon's demands to allow it to use the company's AI model for \\"all lawful purposes\\" expires at 5:01 p.m. ET on Friday.

The AI firm and its CEO, Dario Amodei, have been locked in a standoff with the Pentagon about whether the company will continue to limit the Department of Defense's use of the model. Specifically, Anthropic is asking for assurances that the Pentagon won't use its technology to perform mass surveillance of Americans and produce autonomous weapons.

According to The New York Times, Defense Secretary Pete Hegseth has threatened to invoke the Defense Production Act to force Anthropic to allow the Defense Department to use the AI models as it sees fit. He's also threatened to label the company a supply chain risk, which would prevent the Pentagon from using the company's models.

Labeling Anthropic as a supply chain risk would force the Pentagon's various vendors to cut ties with the company.

In a post on X, chief Pentagon spokesperson Sean Parnell pushed back against Anthropic's demands.

\\"The Department of War has no interest in using AI to conduct mass surveillance of Americans (which is illegal) nor do we want to use AI to develop autonomous weapons that operate without human involvement.\\"

Parnell claimed the assumption that the Pentagon will use Anthropic's tools for the mass surveillance of Americans or to develop autonomous weapons is a fake narrative \\"peddled by leftists in the media.\\"

The global memory shortage is set to impact everything from consumer electronics to enterprise devices, and the smartphone industry, in particular, will face serious headwinds from the dearth of chips.

According to the International Data Corporation (IDC), the smartphone market will see its largest year-over-year decline ever in 2026, plummeting 13% to its lowest levels in a decade.

\\"What we are witnessing is not a temporary squeeze, but a tsunami-like shock originating in the memory supply chain, with ripple effects spreading across the entire consumer electronics industry,” Francisco Jeronimo, vice president of worldwide client devices at IDC, said in a statement.

“The global smartphone market, particularly Android manufacturers, faces a significant threat,\\" he added.

Memory chips are a key component in data centers. But a small number of global manufacturers, including Micron (MU), Samsung (005930.KS), and SK Hynix (000660.KS), means there's only so many to go around. And because data center memory offers higher margins, chipmakers favor it over memory for consumer electronics.

The result: fewer available devices, higher prices, or degraded products with less memory. For consumer electronics companies, that translates to fewer sales.

Yahoo Finance's Francisco Velasquez reports:

The AI supercycle isn't just holding steady — it's getting a massive second wind.

In a new note to clients, Morgan Stanley research analyst Shane Brett raised his forecast for semiconductor capital equipment spending to $143 billion in 2026, up from a previous estimate of $136 billion. The new outlook would represent a 23% increase from the prior year.

He also revised his 2027 forecast to $182 billion, up from $161 billion.

This revision paints a picture of an infrastructure race that is accelerating, even as skeptics wonder when these massive capital expenditures will yield a clear return on investment. And according to Brett, the spending increase is creating a new set of winners.

\\"The market is entering the phase of the cycle where [semiconductor process equipment] returns begin to rival those of memory stocks,\\" Brett said.

Yahoo Finance's Francisco Velasquez reports:

C3.ai (AI) is learning the hard way that \\"conviction\\" doesn't pay the bills.

\\"We did not deliver this quarter, full stop,\\" CEO Stephen Ehikian told Yahoo Finance's Opening Bid. \\"I'm not going to sugarcoat that ... that's on me.\\"

In a remarkably blunt post-earnings admission, Ehikian stated that \\"the reality is we were just burning too much money.\\"

To stop that burn, the company slashed 26% of its workforce, a calculated bid to \\"restructure our cost basis\\" and find the \\"maximum flexibility\\" that Ehikian said is required to capture AI scaling and survive the very market he claims is stronger than ever.

The market's verdict was swift and unforgiving. C3.ai stock cratered nearly 20% following the release as investors looked past the rhetoric and focused on a revenue miss that underscored a complete departure from previous guidance.

The company is expected to unveil new MacBooks, a new lower-cost iPhone, and potentially a new iPad Air, according to MacRumors.

Apple is not expected to livestream a rollout announcement like it typically does during its WWDC event, which is held in September and usually features the announcement of its latest iPhone lineup.

Nvidia (NVDA) made a fortune on its specialized graphics processing units (GPUs) used to power artificial intelligence servers. But on the earnings call Wednesday, CEO Jensen Huang said he's ready to push ahead into making the CPUs, or central processing units, that Intel (INTC) and AMD (AMD) are known for.

Reuters reports:

The CPU is now making a comeback — increasingly seen as an equivalent ​if not better option as AI companies shift from training their models to deploying them — a shift that Nvidia plans to be a big part of.

\\"We love CPUs as well as GPUs,\\" Huang said on a call with analysts on Wednesday for the company's fourth-quarter results.

He assured them that Nvidia was not only ready for the CPU's return to the spotlight but also that Nvidia's own CPU offerings for data centers, first released in 2023, would outcompete rivals.

Last month, at the Consumer Electronics Show in Las Vegas in January, Huang also said the ‌number of high-performance Nvidia CPUs being used in data centers ⁠would explode and that he wouldn't be surprised \\"if Nvidia becomes one of the largest CPU makers in the world.\\"

Meta (META), Microsoft (MSFT), and Amazon (AMZN) ticked modestly lower in the wake of Nvidia's earnings report, even as Nvidia CEO Jensen Huang expressed his vote of confidence in their future cash flows and, therefore, capex spending.

The three hyperscalers moved between 0.1% and 0.4% lower in extended trading, while Nvidia stock pared initial gains during the earnings call to rise 0.5%.

\\"I am confident in their cash flow growing,\\" Huang said of the hyperscalers on the earnings call. \\"The reason for that is very simple: We have now seen the inflection of agentic AI and the usefulness of agents across the world and enterprises everywhere. You're seeing incredible compute demand because of it in this new world of AI. ... In this new world of AI, compute equals revenues.\\"

Other chipmakers, including Intel (INTC) and AMD (AMD), also moved lower in extended trading.

Big Tech giants can't get enough of Nvidia's chips.

Nvidia (NVDA) on Wednesday reported fourth quarter results that topped forecasts and signaled demand for its most advanced chips remains insatiable.

And a growing portion of that demand is coming from the so-called hyperscalers like Microsoft, Amazon, and Meta, who now account for more than half of the company's sales in its data center segment.

\\"Data Center revenue for the fourth quarter was a record $62.3 billion, up 75% from a year ago and up 22% sequentially, driven by the major platform shifts – accelerated computing and AI,\\" Nvidia CFO Colette Kress said in a statement.

\\"For the fourth quarter, hyperscaler revenue increased and remained our largest customer category at slightly over 50% of Data Center revenue, while growth was led by the rest of our Data Center customers as revenue diversified.\\"

The last time the company specified was portion of its data center sales were to these customers, the company said it was \\"approximately\\" 50%.

And while these are small percentage moves, the dollars at this scale are notable, and the increasing portion of sales going to these customers shows where these companies' massive capex plans show up.

Nvidia (NVDA) earnings and revenue both topped Wall Street estimates, sending the stock higher in after-hours trading.

The company also offered Q1 guidance between $76.44 billion and $79.56 billion, above Wall Street's estimates of $72.8 billion without factoring in revenue from China.

Nvidia stock (NVDA) climbed 1.4% on Wednesday as investors eagerly awaited (or braced for) the AI giant's fourth quarter report.

While Nvidia is widely expected to clear expectations, markets have been jumpy around artificial intelligence lately, making the report critical for sentiment across a host of other AI companies and the broader market.

Bloomberg reports:

After powering the market higher for much of the past few years, Nvidia shares have gone cold in recent months, rising about 5% since the start of the fourth quarter — including a more than 2% intraday gain Wednesday — as investors question the hundreds of billions of dollars customers like Alphabet Inc. and Microsoft Corp. are spending on AI. Meanwhile, investors have been fleeing sectors seen as potentially under threat from AI disruption.

“Even if they have tremendous numbers, we know the markets are really fickle,” said Ken Mahoney, president of Mahoney Asset Management.

Samsung's (005930.KS) latest line of Galaxy S26 smartphones features a variety of new AI features as the company seeks to expand its lead in artificial intelligence over Apple (AAPL).

Yahoo Finance's Daniel Howley reports:

The Android-powered Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra, available for preorder Feb. 25, are the latest examples of Samsung’s push to use its AI know-how, powered by its Galaxy AI and Google’s (GOOG, GOOGL) Gemini, as a key differentiator versus Apple’s (AAPL) iPhone.

Smartphone and PC companies are leaning into AI to appeal to shoppers as they look to upgrade their devices, following explosive sales growth in the early days of the pandemic.

“The [smartphone] market is still growing, it's quite healthy, but it's not exploding like it has in the past,” Gartner analyst Tuong Nguyen explained.

“So the key here is moving beyond a technology offering, and more toward ... a lifestyle offering,” Nguyen added.

Yahoo Finance's Jake Conley reports:

In his State of the Union address on Tuesday night, President Trump laid out new guidelines for Big Tech's AI developers: Bring your own power, and pay your own way.

Under a new \\"ratepayer protection pledge,\\" companies building out AI data centers — which consume enormous amounts of energy — will be required to fund their own electricity usage going forward, Trump said.

“We have an old grid, it could never handle the kind of numbers — the amount of electricity — that’s needed,” Trump said. “So I’m telling [companies] they can build their own plant; they’re going to produce their own electricity.”

Details of the new agreement remain sparse, but Energy Secretary Chris Wright said after the State of the Union address that \\"all of the brand-name hyperscalers\\" have signed onto the deal, according to Politico. That category would presumably include companies like Alphabet (GOOG), Meta (META), and Amazon (AMZN).

Bloomberg reports:

Anthropic PBC, which has pledged to make artificial intelligence guardrails a priority, has loosened its central safety policy, saying the move is necessary to keep pace in a rapidly changing field.

The company in 2023 said in its Responsible Scaling Policy that it would delay AI development that might be dangerous. In a Tuesday blog post, Anthropic said it was updating its rules to say it would no longer do so if it believes it lacks a significant lead over a competitor.

“The policy environment has shifted toward prioritizing AI competitiveness and economic growth, while safety-oriented discussions have yet to gain meaningful traction at the federal level,” Anthropic said in its post.

The move is surprising because Anthropic has consistently tried to distinguish itself through its safety stance as it races with OpenAI, Alphabet Inc.’s Google and Elon Musk’s xAI Corp. for dominance in what many view as a revolutionary new technology. Dario Amodei, chief executive officer of Anthropic, used to work at OpenAI and left in part because of his concerns that the startup was prioritizing commercialization and speed over safety.
