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.
Altimeter Capital CEO Brad Gerstner said Thursday that he’s moving out of the “bomb shelter” with Nvidia and into a position of safety, expecting that the chipmaker is positioned to withstand President Donald Trump’s widespread tariffs.
“The growth and the demand for GPUs is off the charts,” he told CNBC’s “Fast Money Halftime Report,” referring to Nvidia’s graphics processing units that are powering the artificial intelligence boom. He said investors just need to listen to commentary from OpenAI, Google and Elon Musk.
President Trump announced an expansive and aggressive “reciprocal tariff” policy in a ceremony at the White House on Wednesday. The plan established a 10% baseline tariff, though many countries like China, Vietnam and Taiwan are subject to steeper rates. The announcement sent stocks tumbling on Thursday, with the tech-heavy Nasdaq down more than 5%, headed for its worst day since 2022.
The big reason Nvidia may be better positioned to withstand Trump’s tariff hikes is because semiconductors are on the list of exceptions, which Gerstner called a “wise exception” due to the importance of AI.
Nvidia’s business has exploded since the release of OpenAI’s ChatGPT in 2022, and annual revenue has more than doubled in each of the past two fiscal years. After a massive rally, Nvidia’s stock price has dropped by more than 20% this year and was down almost 7% on Thursday.
Gerstner is concerned about the potential of a recession due to the tariffs, but is relatively bullish on Nvidia, and said the “negative impact from tariffs will be much less than in other areas.”
He said it’s key for the U.S. to stay competitive in AI. And while the company’s chips are designed domestically, they’re manufactured in Taiwan “because they can’t be fabricated in the U.S.” Higher tariffs would punish companies like Meta and Microsoft, he said.
“We’re in a global race in AI,” Gerstner said. “We can’t hamper our ability to win that race.”
YouTube on Thursday announced new video creation tools for Shorts, its short-form video feed that competes against TikTok.
The features come at a time when TikTok, which is owned by Chinese company ByteDance, is at risk of an effective ban in the U.S. if it’s not sold to an American owner by April 5.
Among the new tools is an updated video editor that allows creators to make precise adjustments and edits, a feature that automatically syncs video cuts to the beat of a song and AI stickers.
The creator tools will become available later this spring, said YouTube, which is owned by Google.
Along with the new features, YouTube last week said it was changing the way view counts are tabulated on Shorts. Under the new guidelines, Shorts views will count the number of times the video is played or replayed with no minimum watch time requirement.
Previously, views were only counted if a video was played for a certain number of seconds. This new tabulation method is similar to how views are counted on TikTok and Meta’s Reels, and will likely inflate view counts.
“We got this feedback from creators that this is what they wanted. It’s a way for them to better understand when their Shorts have been seen,” YouTube Chief Product Officer Johanna Voolich said in a YouTube video. “It’s useful for creators who post across multiple platforms.”

Technology stocks plummeted Thursday after President Donald Trump’s new tariff policies sparked widespread market panic.
Apple led the declines among the so-called “Magnificent Seven” group, dropping nearly 9%. The iPhone maker makes its devices in China and other Asian countries. The stock is on pace for its steepest drop since 2020.
Other megacaps also felt the pressure. Meta Platforms and Amazon fell more than 7% each, while Nvidia and Tesla slumped more than 5%. Nvidia builds its new chips in Taiwan and relies on Mexico for assembling its artificial intelligence systems. Microsoft and Alphabet both fell about 2%.
The drop in technology stocks came amid a broader market selloff spurred by fears of a global trade war after Trump unveiled a blanket 10% tariff on all imported goods and a range of higher duties targeting specific countries after the bell Wednesday. He said the new tariffs would be a “declaration of economic independence” for the U.S.
Companies and countries worldwide have already begun responding to the wide-sweeping policy, which included a 34% tariff on China stacked on a previous 20% tax, a 46% duty on Vietnam and a 20% levy on imports from the European Union.
China’s Ministry of Commerce urged the U.S. to “immediately cancel” the unilateral tariff measures and said it would take “resolute counter-measures.”
The tariffs come on the heels of a rough quarter for the tech-heavy Nasdaq and the worst period for the index since 2022. Stocks across the board have come under pressure over concerns of a weakening U.S. economy. The Nasdaq Composite dropped nearly 5% on Thursday, bringing its year-to-date loss to 13%.
Trump applauded some megacap technology companies for investing money into the U.S. during his speech, calling attention to Apple’s plan to spend $500 billion over the next four years.
