Redwood Materials, the battery-recycling startup founded by Tesla board member JB Straubel, recently nabbed Tesla’s vice president of powertrain engineering, Colin Campbell, to serve as chief technology officer.
Based in Carson City, Nevada, Redwood was founded by Straubel in 2017 while he was still serving as Tesla’s CTO. Straubel resigned from Tesla in 2019 to focus on Redwood.
Campbell announced the move on LinkedIn on Monday, capping a 17-year tenure working for Elon Musk’s electric vehicle company in a variety of engineering and leadership roles. He thanked his former colleagues at Tesla for a “once-in-a-lifetime experience.”
“At Redwood, I will continue to work on electrification — but this time, ensuring broad EV and clean energy adoption by solving problems further upstream!” Campbell wrote. “Redwood’s mission is to create a circular battery supply chain, localizing the current fragmented system by creating critical battery components at scale in the US for the first time — and from an ever-increasing amount of recycled content.”
Redwood turns end-of-life electric vehicle batteries and scrap from car factories into raw materials and components to make new battery cells. Straubel told CNBC in February that the company also blends “sustainably mined material” in its manufacturing processes.
Campbell’s departure from Tesla follows an announcement earlier this month that the company’s finance chief, Zach Kirkhorn, was stepping down, to be replaced by Tesla accounting chief Vaibhav Taneja, who now holds both the chief financial officer and accounting role, according to Tesla’s shareholder disclosure.
Redwood has lured top talent away from Tesla for years. Another executive at Redwood, operating chief Kevin Kassekert, previously served as vice president of people and places at Tesla. More than 120 people currently work at Straubel’s company after previously working for Tesla, according to LinkedIn data.
Straubel, who is credited as a co-founder of Tesla, was elected by the automaker’s shareholders earlier this year to serve as an independent director on the board.
Tesla did not immediately respond to CNBC’s request for comment.
President Trump’s new tariffs on goods that the U.S. imports from over 100 countries will have an effect on consumers, former Microsoft CEO Steve Ballmer told CNBC on Friday. Investors will feel the pain, too.
Microsoft’s stock dropped almost 6% in the past two days, as the Nasdaq wrapped up its worst week in five years.
“As a Microsoft shareholder, this kind of thing is not good,” Ballmer said, in an interview with Andrew Ross Sorkin that was tied to Microsoft’s 50th anniversary celebration. “It creates opportunity to be a serious, long-term player.”
Ballmer was sandwiched in between Microsoft co-founder Bill Gates and current CEO Satya Nadella for the interview.
“I took just enough economics in college — that tariffs are actually going to bring some turmoil,” said Ballmer, who was succeeded by Nadella in 2014. Gates, Microsoft’s first CEO, convinced Ballmer to join the company in 1980.
Gates, Ballmer and Nadella attended proceedings at Microsoft’s Redmond, Washington, campus on Friday to celebrate its first half-century.
Between the tariffs and weak quarterly revenue guidance announced in January, Microsoft’s stock is on track for its fifth straight month of declines, which would be the worst stretch since 2009. But the company remains a leader in the PC operating system and productivity software markets, and its partnership with startup OpenAI has led to gains in cloud computing.
“I think that disruption is very hard on people, and so the decision to do something for which disruption was inevitable, that needs a lot of popular support, and nobody could game theorize exactly who is going to do what in response,” Ballmer said, regarding the tariffs. “So, I think citizens really like stability a lot. And I hope people — individuals who will feel this, because people are feeling it, not just the stock market, people are going to feel it.”
Ballmer, who owns the Los Angeles Clippers, is among Microsoft’s biggest fans. He said he’s the company’s largest investor. In 2014, shortly after he bought the basketball team for $2 billion, he held over 333 million shares of the stock, according to a regulatory filing.
“I’m not going to probably have 50 more years on the planet,” he said. “But whatever minutes I have, I’m gonna be a large Microsoft shareholder.” He said there’s a bright future for computing, storage and intelligence. Microsoft launched the first Azure services while Ballmer was CEO.
Earlier this week Bloomberg reported that Microsoft, which pledged to spend $80 billion on AI-enabled data center infrastructure in the current fiscal year, has stopped discussions or pushed back the opening of facilities in the U.S. and abroad.
JPMorgan Chase’s chief economist, Bruce Kasman, said in a Thursday note that the chance of a global recession will be 60% if Trump’s tariffs kick in as described. His previous estimate was 40%.
“Fifty years from now, or 25 years from now, what is the one thing you can be guaranteed of, is the world needs more compute,” Nadella said. “So I want to keep those two thoughts and then take one step at a time, and then whatever are the geopolitical or economic shifts, we’ll adjust to it.”
Gates, who along with co-founder Paul Allen, sought to build a software company rather than sell both software and hardware, said he wasn’t sure what the economic effects of the tariffs will be. Today, most of Microsoft’s revenue comes from software. It also sells Surface PCs and Xbox consoles.
“So far, it’s just on goods, but you know, will it eventually be on services? Who knows?” said Gates, who reportedly donated around $50 million to a nonprofit that supported Democratic nominee Kamala Harris’ losing campaign.
AppLovin CEO Adam Foroughi provided more clarity on the ad-tech company’s late-stage effort to acquire TikTok, calling his offer a “much stronger bid than others” on CNBC’s The Exchange Friday afternoon.
Foroughi said the company is proposing a merger between AppLovin and the entire global business of TikTok, characterizing the deal as a “partnership” where the Chinese could participate in the upside while AppLovin would run the app.
“If you pair our algorithm with the TikTok audience, the expansion on that platform for dollars spent will be through the roof,” Foroughi said.
The news comes as President Trump announced he would extend the deadline a second time for TikTok’s Chinese-owned parent company ByteDance to sell the U.S. subsidiary of TikTok to an American buyer or face an effective ban on U.S. app stores. The new deadline is now in June, which, as Foroughi described, “buys more time to put the pieces together” on AppLovin’s bid.
“The president’s a great dealmaker — we’re proposing, essentially an enhancement to the deal that they’ve been working on, but a bigger version of all the deals contemplated,” he added.
AppLovin faces a crowded field of other interested U.S. backers, including Amazon, Oracle, billionaire Frank McCourt and his Project Liberty consortium, and numerous private equity firms. Some proposals reportedly structure the deal to give a U.S. buyer 50% ownership of the company, rather than a complete acquisition. The Chinese government will still need to approve the deal, and AppLovin’s interest in purchasing TikTok in “all markets outside of China” is “preliminary,” according to an April 3 SEC filing.
Correction: A prior version of this story incorrectly characterized China’s ongoing role in TikTok should AppLovin acquire the app.

President Donald Trump announced an aggressive, far-reaching “reciprocal tariff” policy this week, leaving many economists and U.S. trade partners to question how the White House calculated its rates.
Trump’s plan established a 10% baseline tariff on almost every country, though many nations such as China, Vietnam and Taiwan are subject to much steeper rates. At a ceremony inthe Rose Garden on Wednesday, Trump held up a poster board that outlined the tariffs that it claims are “charged” to the U.S., as well as the “discounted” reciprocal tariffs that America would implement in response.
Those reciprocal tariffs are mostly about half of what the Trump administration said each country has charged the U.S. The poster suggests China charges a tariff of 67%, for instance, and that the U.S. will implement a 34% reciprocal tariff in response.
However, a report from the Cato Institute suggests the trade-weighted average tariff rates in most countries are much different than the figures touted by the Trump administration. The report is based on trade-weighted average duty rates from the World Trade Organization in 2023, the most recent year available.
The Cato Institute says the 2023 trade-weighted average tariff rate from China was 3%. Similarly, the administration says the EU charges the U.S. a tariff of 39%, while the 2023 trade-weighted average tariff rate was 2.7%, according to the report.
In India, the Trump administration claims that a 52% tariff is charged against the U.S., but Cato found that the 2023 trade-weighted average tariff rate was 12%.
Many users on social media this week were quick to notice that the U.S. appeared to have divided the trade deficit by imports from a given country to arrive at tariff rates for individual countries. It’s an unusual approach, as it suggests that the U.S. factored in the trade deficit in goods but ignored trade in services.
The Office of the U.S. Trade Representative briefly explained its approach in a release, and stated that computing the combined effects of tariff, regulatory, tax and other policies in various countries “can be proxied by computing the tariff level consistent with driving bilateral trade deficits to zero.”
“If trade deficits are persistent because of tariff and non-tariff policies and fundamentals, then the tariff rate consistent with offsetting these policies and fundamentals is reciprocal and fair,” the USTR said in the release.
