Musk, the world’s richest person, started going after Navarro over the weekend, posting on X that a “PhD in econ from Harvard is a bad thing, not a good thing,” a reference to Navarro’s degree. Whatever subtlety remained at the beginning of the week has since vanished.
On Tuesday, Musk wrote that “Navarro is truly a moron,” noting that his comments about Tesla being a “car assembler,” as much are “demonstrably false.” Musk called Navarro “dumber than a sack of bricks,” before later apologizing to bricks. Musk also called Navarro “dangerously dumb.”
Musk’s attacks on Navarro represent the most public spat between members of President Trump’s inner circle since the term began in January, and show that the steep tariffs announced last week on more than 180 countries and territories don’t have universal approval in the administration.
When asked about the feud in a briefing on Tuesday, White House press secretary Karoline Leavitt said, “Look, these are obviously two individuals who have very different views on trade and on tariffs.”
“Boys will be boys, and we will let their public sparring continue,” she said.
For Musk, whose younger brother Kimbal — a restaurant owner, entrepreneur and Tesla board member — has joined in on the action, the name-calling appears to be tied to business conditions.
Tesla’s stock is down 22% in the past four trading sessions and 45% for the year. Tesla has lost more tha $585 billion in value since the calendar turned, equaling tens of billions of dollars in paper losses for Musk, who is also CEO of SpaceX and the owner of xAI and social network X.
Even before President Trump detailed his plan for widespread tariffs, he’d already placed a 25% tariff on vehicles not assembled in the U.S. Many analysts said Tesla could withstand those tariffs better than competitors because its vehicles sold in the U.S. are assembled domestically.
But the company’s production costs are poised to increase because of the tariffs on materials and parts from foreign suppliers. Canada and Mexico are among the leading sources of U.S. steel imports, and Canada is the nation’s largest supplier of aluminum, while China and Mexico are home to major suppliers of printed circuit boards to the automotive industry.
At a recent an event hosted by right-wing Italian Deputy Prime Minister Matteo Salvini, Musk said, “Both Europe and the United States should move, ideally, in my view, to a zero-tariff situation, effectively creating a free trade zone between Europe and North America.”
Musk, whose view on trade relations with Europe stands in stark contrast to the policies implemented by the president, has a vested interest in the region. Tesla has a large car factory outside of Berlin, and the European Commission previously turned to SpaceX for launches.
Even before the tariffs, Tesla’s business was faltering. Last week, the company reported a 13% year-over-year decline in first-quarter deliveries, missing analysts’ estimates. That report that landed days after Tesla’s stock price wrapped up its worst quarter since 2022.
Musk, who spent roughly $290 billion to help return Trump to the White House, is now leading the Department of Government Efficiency, or DOGE, which has slashed costs, eliminated regulations and cut tens of thousands of federal jobs. In the first quarter, Tesla was hit with waves of protests, boycotts and some criminal activity that targeted vehicles and facilities in response to Musk’s political rhetoric and his work in the White House.
TikTok CEO Shou Zi Chew told employees on Thursday that the company’s U.S. operations will be housed in a new joint venture.
The entity is named TikTok USDS Joint Venture LLC, according to a memo sent by Chew and obtained by CNBC. As part of the joint venture, Chew said the company has signed agreements with the three managing investors: Oracle, Silver Lake, and Abu Dhabi-based MGX. He said that the deal’s “closing date” is Jan. 22.
Under a national security law, which the Supreme Court upheld in January, China-based ByteDance was required to divest TikTok’s U.S. operations or face an effective ban in the country. In September, President Donald Trump signed an executive order approving a proposed deal that would keep TikTok operational in the U.S. by meeting the requirements of a law originally signed by former President Joe Biden.
Chew noted that the new TikTok joint venture would be “majority owned by American investors, governed by a new seven-member majority-American board of directors, and subject to terms that protect Americans’ data and U.S. national security.”
The U.S. joint venture will be 50% held by a consortium of new investors, including Oracle, Silver Lake and MGX with 15% each. Just over 30% will be held by affiliates of certain existing investors of ByteDance, and 19.9% will be retained by ByteDance, the memo said.
The TikTok chief said the entity will be responsible for protecting U.S. data, ensuring the security of its prized algorithm, content moderation and “software assurance.” He added that the joint venture will “have the exclusive right and authority to provide assurances that content, software, and data for American users is secure.”
In addition to being an investor, Oracle will serve as the “trusted security partner” in charge of auditing and validating that it complies with “agreed upon National Security Terms,” the memo said. Sensitive U.S. data will be stored in Oracle’s U.S.-based cloud computing data centers, Chew wrote.
The new TikTok entity will also be tasked with retraining the video app’s core content recommendation algorithm “on U.S. user data to ensure the content feed is free from outside manipulation,” the memo said.
Chew noted that TikTok global U.S. entities “will manage global product interoperability and certain commercial activities, including e-commerce, advertising, and marketing.”
Under Trump’s executive order in September, the attorney general was blocked from enforcing the national security law for a 120-day period in order to “permit the contemplated divestiture to be completed,” allowing the deal to finalize by Jan 23.
The VC arms of Google and Nvidia have invested in Swedish vibe coding startup Lovable’s $330 million Series B at a $6.6 billion valuation, the company announced on Thursday.
The news confirms an earlier story from CNBC, which reported on Tuesday that Lovable had raised at that valuation, trebling its valuation from its previous round in July, and that the investors included U.S. VC firms Accel and Khosla Ventures.
CapitalG, one of Google’s VC divisions, and Menlo Ventures led the round. Alongside Accel and Khosla, Nvidia venture arm NVentures, actor Gwyneth Paltrow’s VC firm Kinship Ventures, Salesforce Ventures, Databricks Ventures, Atlassian Ventures, T.Capital, Hubspot Ventures, DST Global, EQT Global, Creandum and Evantic also participated.
The fresh funds take Lovable’s total raised in 2025 to over $500 million.
“Lovable has done something rare: built a product that enterprises and founders both love,” said Laela Sturdy, managing partner at CapitalG in a statement accompanying the announcement.
“The demand we’re seeing from Fortune 500 companies signals a fundamental shift in how software gets built.”
Lovable’s platform uses AI models from providers like OpenAI and Anthropic to help users build apps and websites using text prompts, without technical knowledge of coding.
The startup reported $200 million in annual recurring revenue (ARR) in November, just under a year after achieving $1 million in ARR for the first time. It was founded in 2023 by Anton Osika and Fabian Hedin.
Vibe coding startups have seen big interest from VCs in recent times, as investors bet on their promise of drastically reducing the time it takes to create software and apps.
In the U.S., Anysphere, which created coding tool Cursor, raised $2.3 billion at a $29.3 billion valuation in November. In September, Replit hit a $3 billion price tag after picking up $250 million and Vercel closed a $300 million round at a $9.3 billion valuation.
During an earnings call with analysts, Micron, which makes memory storage used for computers and artificial intelligence servers, said data center needs have fueled greater demand for its products.
Micron said it expects the total addressable market for high-bandwidth memory to hit $100 billion by 2028, growing at a 40% compounded annual growth rate. Management also upped its capital expenditures guidance to $20 billion from $18 billion.
“We are more than sold out,” said business chief Sumit Sadana. “We have a significant amount of unmet demand in our models and this is just consistent with an environment where the demand is substantially higher than supply for the foreseeable future.
Micron topped Wall Street estimates for the fiscal first quarter and issued blowout guidance.
