Elon Musk and President Donald Trump are fighting again. Now Musk’s business interests — and the billions in government contracts they enjoy — are once again in the crosshairs.

Investors were already punishing Tesla on Tuesday, sending shares in the electric carmaker more than 4% lower in afternoon trading. The stock has experienced a late-spring rally alongside the broader market but remains down some 20% so far this year. The shares have been pummeled by a global backlash to Musk’s alliance with Trump on the campaign trail and in the White House, where the multibillionaire led a sweeping program of government cuts

Musk acknowledged there had been “some blowback” to the actions taken by his Department of Government Efficiency project that may have affected Tesla sales. Yet investors remain largely bullish on the company and its efforts to pivot away from mass-market EVs and toward self-driving taxis and robotics, pushing its market valuation back toward $1 trillion.

Tesla remains Musk’s best-known business, but its fortunes are less directly tied to the government than SpaceX, his rocket-building company. SpaceX’s $350 billion valuation largely rests on the many government contracts that fuel it. SpaceX’s work for NASA has ramped up in recent years in support of the Artemis mission to return to the moon.

Meanwhile, SpaceX’s Dragon spacecraft is currently the only active vessel capable of carrying astronauts to and from the International Space Station. SpaceX has also become essential to the Department of Defense’s missions taking satellites into orbit and today is responsible for the majority of such missions, according to Ars Technica.

SpaceX is privately held, meaning its shares don’t trade on the open market. It is thus difficult to get a real-time gauge on how worsening relations could affect the company’s fortunes. But the impact could be substantial. Since fiscal year 2000, total revenue for SpaceX and Tesla from federal unclassified contracts sits at $22.5 billion, according to Bloomberg Government data — with most of those going to the former. The Washington Post has put the figure for SpaceX alone at close to $38 billion, with $6.3 billion alone coming in 2024 — the highest annual total to date.

The dispute with Trump has also taken a chunk out of Musk’s personal net worth. After soaring to an all-time high of nearly half a trillion dollars after Trump’s election win, Musk’s publicly available wealth tally now sits at $400 billion, though that still makes him the world’s wealthiest individual by nearly $150 billion ahead of Oracle founder Larry Ellison, another Trump ally.

The Musk-Trump tiff first exploded into public view last month, shortly after Musk formally stepped down from his special government employee role and criticized the massive spending and tax cut bill that Republican senators passed Tuesday. Trump responded at the time by threatening to “terminate Elon’s Governmental Subsidies and Contracts.”

Musk, in turn, said he would begin “decommissioning” the Dragon, only to reverse course hours later after an X user advised him and Trump to “cool off and take a step back for a couple of days.”

Before their initial flare-up subsided, Musk announced he would be reining in his political spending weeks after a candidate he had backed lost a key Wisconsin Supreme Court race. Some analysts believe the current relapse in tensions between the two men will be short-lived given Musk’s reliance on the government, and vice-versa.

Still, Musk is now discussing launching his own political party to address the U.S.’s fiscal imbalances, which he believes Trump’s bill will exacerbate — a contention supported by the nonpartisan Congressional Budget Office. While the South Africa-born executive is ineligible to run for office, any candidate he backed for national office would likely face immediate conflict-of-interest questions.

Apple has accused a former engineer for its Vision Pro headset computer of stealing company trade secrets before starting a new job at Snap, according to a lawsuit filed in California last week.

In the June 24 court filing, Apple accuses Di Liu, a senior design engineer, of downloading thousands of documents in his final days at the Cupertino company last year and saving them to his personal cloud accounts.

This lawsuit is the latest example of Apple publicly going after a former employee for leaking internal information. Apple is an intensely secretive company, and lawsuits like this one highlight how the iPhone maker exercises tight control over its internal information, even if it has to pursue legal action against former staff.

Apple alleges that Liu didn’t inform the company when he resigned late last year that he was headed to Snap, a competitor and maker of smart glasses. As a result, Apple did not shut off his access to accounts and allowed him a customary two-week transition period, which he used to download company files, according to the lawsuit.

“Worse still, the review of Mr. Liu’s Apple-issued work laptop also shows that while maintaining access to Apple’s Proprietary Information under false pretenses, he used his Apple credentials to exfiltrate thousands of documents containing Proprietary Information from Apple’s secure file storage systems,” the iPhone maker’s lawyers said in the filing.

Many of the files downloaded by Liu had codenames for Apple projects and described the company’s technology, product design and supply chain, according to the lawsuit. Apple says that all employees agree to keep Apple files confidential and that Liu broke confidentiality agreements he made when he joined. Liu worked for Apple between 2017 and 2024, according to the lawsuit.

Liu worked on Apple’s Vision Pro headset as a system product design engineer, per the filing. Liu did not respond to a request for comment from CNBC.

Apple lawyers wrote that Liu could use the trade secrets in his work at Snap. Apple is not suing Snap, and the social media company did not respond to a request for comment.

“The overlap between Apple’s Proprietary Information that Mr. Liu retained and Snap’s AR products (for which Mr. Liu is a ‘product design engineer’) suggests that Mr. Liu intends to use Apple’s Proprietary Information at Snap,” according to the filing.

Apple is seeking damages and for Liu to have his devices inspected by a forensic examiner to make sure all the trade secrets are deleted.

The iPhone maker has sued several former employees in recent years for taking files when they left the company.

Apple settled with former engineer Simon Lancaster in 2022 over providing information to a journalist. Apple also sued a former employee, Andrew Aude, in 2024 over leaking details to the media. That lawsuit was dismissed after Aude apologized.

The Cupertino company sued Rivos, a chip startup staffed by former Apple semiconductor employees, over its intellectual property, and settled in 2024.

Additionally at least three former Apple employees have also been arrested and accused by the government of taking company secrets and giving them to China-linked organizations. One pled guilty and was sentenced to four months in prison, and two are still in proceedings.

Microsoft said Wednesday that it will lay off about 9,000 employees. The move will affect less than 4% of its global workforce across different teams, geographies and levels of experience, a person familiar with the matter told CNBC.

The announcement comes on the second day of Microsoft’s 2026 fiscal year. Executives at the Redmond, Washington-based company typically unveil reorganizations at the time of the new fiscal year.

“We continue to implement organizational changes necessary to best position the company and teams for success in a dynamic marketplace,” a Microsoft spokesperson said in an email.

Microsoft has held several rounds of layoffs already this calendar year. In January, it cut less than 1% of headcount based on performance. The 50-year-old software company slashed more than 6,000 jobs in May and then at least 300 more in June. As of June 2024 it employed 228,000 people. In 2023, it laid off 10,000.

Perhaps the largest culling of Microsoft workers came in 2014, when the company eliminated 18,000 after acquiring Nokia’s devices and services business.

As was the case with the May layoffs, Microsoft is looking to reduce the number of layers of managers that stand between individual contributors and top executives, said the person who asked not to be named while discussing internal matters.

“To position Gaming for enduring success and allow us to focus on strategic growth areas, we will end or decrease work in certain areas of the business and follow Microsoft’s lead in removing layers of management to increase agility and effectiveness,” Phil Spencer, Microsoft’s CEO of gaming, wrote in a Wednesday memo to employees in that division.

Microsoft reported nearly $26 billion in net income on $70 billion in revenue for the March quarter. The numbers were well ahead of Wall Street’s consensus, keeping Microsoft ranked as one of the most profitable companies in the S&P 500 index, according to data compiled by FactSet.

Executives called for about 14% year-over-year revenue growth in the June quarter, thanks to expected expansion in Azure cloud services and corporate productivity software subscriptions

Microsoft stock closed at a record high of $497.45 per share on June 26. At the start of Wednesday’s trading session, the shares were down about 0.6%, while the S&P 500 was roughly flat.

Autodesk, Chegg and CrowdStrike are among the other software providers that have slimmed down in 2025. Earlier on Wednesday, payroll processing company ADP said the U.S. private sector lost 33,000 jobs in June. Economists polled by Dow Jones had predicted an increase of 100,000.
