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.

AeroVironment shares fell 7% Tuesday after the defense contractor said it plans to offer $750 million in common stock and $600 million in convertible senior notes due in 2030 to repay debt.
The drone maker said it would use leftover funding for general purposes such as boosting manufacturing capacity.
AeroVironment shares have soared 85% this year, ballooning its market value to about $13 billion.
Last week, shares of the Arlington, Virginia-based company rallied on strong fourth-quarter results, lifting higher as CNBC’s Jim Cramer called it the “next Palantir of hardware.”
Last month, the company also closed its $4.1 billion acquisition of space-related defense tech company Blue Halo.
Earlier this month, President Donald Trump signed an executive order intended to boost drone production in the U.S. and crack down on unauthorized uses.
The company also has a high short interest level, which may have contributed to some of the recent gains, creating a short squeeze. This phenomenon occurs when a stock price surges, forcing those shorting the stock to purchase shares to cover their positions and prevent losses.

Internet firm Cloudflare will start blocking artificial intelligence crawlers from accessing content without website owners’ permission or compensation by default, in a move that could significantly impact AI developers’ ability to train their models.
Starting Tuesday, every new web domain that signs up to Cloudflare will be asked if they want to allow AI crawlers, effectively giving them the ability to prevent bots from scraping data from their websites.
Cloudflare is what’s called a content delivery network, or CDN. It helps businesses deliver online content and applications faster by caching the data closer to end-users. They play a significant role in making sure people can access web content seamlessly every day.
Roughly 16% of global internet traffic goes directly through Cloudflare’s CDN, the firm estimated in a 2023 report.
“AI crawlers have been scraping content without limits. Our goal is to put the power back in the hands of creators, while still helping AI companies innovate,” said Matthew Prince, co-founder and CEO of Cloudflare, in a statement Tuesday.
“This is about safeguarding the future of a free and vibrant Internet with a new model that works for everyone,” he added.
What are AI crawlers?
AI crawlers are automated bots designed to extract large quantities of data from websites, databases and other sources of information to train large language models from the likes of OpenAI and Google.
Whereas the internet previously rewarded creators by directing users to original websites, according to Cloudflare, today AI crawlers are breaking that model by collecting text, articles and images to generate responses to queries in a way that users don’t need to visit the original source.
This, the company adds, is depriving publishers of vital traffic and, in turn, revenue from online advertising.
Tuesday’s move builds on a tool Cloudflare launched in September last year that gave publishers the ability to block AI crawlers with a single click. Now, the company is going a step further by making this the default for all websites it provides services for.
OpenAI says it declined to participate when Cloudflare previewed its plan to block AI crawlers by default on the grounds that the content delivery network is adding a middleman to the system.
The Microsoft-backed AI lab stressed its role as a pioneer of using robots.txt, a set of code that prevents automated scraping of web data, and said its crawlers respect publisher preferences.
“AI crawlers are typically seen as more invasive and selective when it comes to the data they consumer. They have been accused of overwhelming websites and significantly impacting user experience,” Matthew Holman, a partner at U.K. law firm Cripps, told CNBC.
“If effective, the development would hinder AI chatbots’ ability to harvest data for training and search purposes,” he added. “This is likely to lead to a short term impact on AI model training and could, over the long term, affect the viability of models.”
