Shares in some chipmakers dipped on Thursday after electric vehicle maker Tesla said it plans to greatly reduce the use of silicon carbide transistors in its next-generation vehicle powertrains.
At Tesla’s 2023 Investor Day presentation on Wednesday, which largely focused on efficiency and controlling costs, powertrain engineering leader Colin Campbell took the stage to show how the company plans to reduce the cost of their cars’ powertrains, while maintaining high performance and energy efficiency.
Campbell revealed that, “In our next powertrain, the silicon carbide transistors that I mentioned, that are key component[s] but expensive, we figured out a way to use 75% less without compromising the performance or the efficiency of the car.”
Shares of ON Semiconductor and ST Microelectronics were each down more than 4%, while Wolfspeed dropped more than 9% and MP Materials more than 12% in mid-day trading, as investors worried that Tesla’s moves would be a harbinger for the automotive industry.
Campbell did not say when the company’s next-generation powertrain would be ready for high-volume production and use in the company’s vehicles, nor did he specify how much it currently spends on these transistors. Executives at the event did not reveal any firm details about the “next gen” Tesla, which some analysts refer to as the Model 2.
Chips made with silicon carbide transistors are widely used in electric vehicles. Generally, they withstand more heat, have a longer life and are more energy-efficient than semiconductors made with silicon power transistors, according to the Institute of Electrical and Electronic Engineers.
Bank of America analysts called Tesla’s claims “notable but premature.”
However, the analysts acknowledged, “If true, this technological advancement could be a major risk for the SiC materials industry (WOLF, COHR, Rohm) and devices (ON and European peers STMicro, Infineon – covered by Didier Scemama).”
They added the possibility that “cheaper [silicon carbide chips] could drive up EV adoption globally so what vendors lose on content could be partially offset by greater EV volumes.”
New Street Research analysts agreed generally, and wrote in a note on Thursday that the announcement from Tesla is actually a good thing for chipmakers as they expect demand to remain high throughout and beyond the EV industry.
They wrote of Tesla’s announcement: “The inverter of the new drivetrain will use a hybrid architecture,” that mixes silicon and silicon carbide transistors, with both types of transistors working together to handle peak loads in a Tesla vehicle, primarily during the vehicle’s acceleration. “This hybrid architecture is for the new platform only, i.e. a low-cost, small, lower-performance car, and will not be adopted for existing models (S, X, 3, Y), or the Cybertruck.”
New Street does not expect a lower-priced, next generation Tesla vehicle to “ramp in volumes before 2025 or 2026.”
Wells Fargo analysts are maintaining an overweight rating on shares of both Wolfspeed and OnSemi with a price target for Wolfspeed of $110 and a price target for OnSemi of $95.
Citing Yole Group in a note on Thursday, Wells Fargo analysts said in the near term the silicon carbide chip supply chain will remain tight due to strong demand from automakers across the board. Every growing EV maker will seek to scale up while controlling costs but in the near term, they will be more concerned about securing a supply of silicon carbide chips for their new models, many of which are set to launch this year and next, they said.

Amazon was questioned by House China committee over ‘dangerous and unwise’ TikTok partnership

Amazon representatives met with the House China committee in recent months to discuss lawmaker concerns over the company’s partnership with TikTok, CNBC confirmed.
A spokesperson for the House Select Committee on the Chinese Communist Party confirmed the meeting, which centered on a shopping deal between Amazon and TikTok announced in August. The agreement allows users of TikTok, owned by China’s ByteDance, to link their account with Amazon and make purchases from the site without leaving TikTok.
“The Select Committee conveyed to Amazon that it is dangerous and unwise for Amazon to partner with TikTok given the grave national security threat the app poses,” the spokesperson said. The parties met in September, according to Bloomberg, which first reported the news.
Representatives from Amazon and TikTok did not immediately respond to CNBC’s request for comment.
TikTok’s future viability in the U.S. is uncertain. In April, President Joe Biden signed a law that requires ByteDance to sell TikTok by Jan. 19. If TikTok fails to cut ties with its parent company, app stores and internet hosting services would be prohibited from offering the app.
President-elect Donald Trump could rescue TikTok from a potential U.S. ban. He promised on the campaign trail that he would “save” TikTok, and said in a March interview with CNBC’s “Squawk Box” that “there’s a lot of good and there’s a lot of bad” with the app.
In his first administration, Trump had tried to implement a TikTok ban. He changed his stance around the time he met with billionaire Jeff Yass. The Republican megadonor’s trading firm, Susquehanna International Group, owns a 15% stake in ByteDance, while Yass has a 7% stake in the company, NBC and CNBC reported in March.

Amazon launches fixed pricing for treatment of conditions such as hair loss. Hims & Hers stock drops 15%
Former U.S. Army intelligence analyst Chelsea Manning says censorship is still “a dominant threat,” advocating for a more decentralized internet to help better protect individuals online.
Her comments come amid ongoing tension linked to online safety rules, with some tech executives recently seeking to push back over content moderation concerns.
Speaking to CNBC’s Karen Tso at the Web Summit tech conference in Lisbon, Portugal, on Wednesday, Manning said that one way to ensure online privacy could be “decentralized identification,” which gives individuals the ability to control their own data.
“Censorship is a dominant threat. I think that it is a question of who’s doing the censoring, and what the purpose is — and also censorship in the 21st century is more about whether or not you’re boosted through like an algorithm, and how the fine-tuning of that seems to work,” Manning said.
“I think that social media and the monopolies of social media have sort of gotten us used to the fact that certain things that drive engagement will be attractive,” she added.
“One of the ways that we can sort of countervail that is to go back to the more decentralized and distribute the internet of the early ’90s, but make that available to more people.”

Asked how tech companies could make money in such a scenario, Manning said there would have to be “a better social contract” put in place to determine how information is shared and accessed.
“One of the things about distributed or decentralized identification is that through encryption you’re able to sort of check the box yourself, instead of having to depend on the company to provide you with a check box or an accept here, you’re making that decision from a technical perspective,” Manning said.
‘No longer secrecy versus transparency’
Manning, who works as a security consultant at Nym Technologies, a company that specializes in online privacy and security, was convicted of espionage and other charges at a court-martial in 2013 for leaking a trove of secret military files to online media publisher WikiLeaks.
She was sentenced to 35 years in prison, but was later released in 2017, when former U.S. President Barack Obama commuted her sentence.
Asked to what extent the environment has changed for whistleblowers today, Manning said, “We’re at an interesting time because information is everywhere. We have more information than ever.”
She added, “Countries and governments no longer seem to invest the same amount of time and effort in hiding information and keeping secrets. What countries seem to be doing now is they seem to be spending more time and energy spreading misinformation and disinformation.”
Manning said the challenge for whistleblowers now is to sort through the information to understand what is verifiable and authentic.
“It’s no longer secrecy versus transparency,” she added.
