NEW YORK, June 18, 2026, 18:05 EDT
- Wolfspeed ended the session at $57.41, gaining 17.91%. The stock hit an intraday high of $57.50.
- Wolfspeed after the bell filed to register as much as 24.07 million shares for resale by selling stockholders. The company said it won’t get any proceeds from the sale.
- U.S. markets shut for Juneteenth on Friday. Investors will have to wait until Monday for the next regular session to get a look at the filing.
Wolfspeed Inc. climbed almost 18% Thursday, stretching its rebound. The silicon carbide chipmaker then posted an after-hours filing that brought up a new question about where future stock supply might come from.
The stock finished at $57.41 for a 17.91% gain, trading in a range from $47.82 to $57.50, Google Finance data showed. The jump happened as risk assets rallied. The Nasdaq Composite added 1.9%, while the Russell 2000 advanced 2.1%.
Timing is key. Traders have turned Wolfspeed into a hot play on silicon carbide, a chip material that can take on high-voltage energy with less loss than standard silicon. Now it’s about whether the Durham, North Carolina firm can use that edge to move beyond last year’s restructuring and get a bigger foothold in AI data centers, aerospace and industrial power.
Wolfspeed filed a shelf prospectus after the close, setting up a potential sale by existing shareholders. The registration statement covers 24,072,041 shares, which includes shares outstanding, stock from pre-funded warrants, and any shares from converting 3.5% convertible senior secured notes due 2031.
Wolfspeed said there’s no sale of securities by the company under the prospectus, and it isn’t getting any money from these sales. Selling stockholders pick the timing, the amount, and the price for any sales, the company said. Wolfspeed said just registering the shares doesn’t mean the holders will actually sell.
Monday’s overhang is traders watching that resale filing. It’s not an immediate stock sale, but those moves sometimes make the tape jittery if people figure more shares could hit after a quick rally. Wolfspeed listed 51.97 million shares outstanding as of May 31 in the filing, with 72.79 million shares outstanding if holders exercise all the pre-funded warrants and convert the 1.5-lien notes tied to this filing.
GE Aerospace and Wolfspeed said June 8 they signed a memorandum of understanding to develop high-voltage silicon carbide power modules for use in industrial, aerospace and defense sectors. Wolfspeed CEO Robert Feurle pointed to a “power-delivery crunch” in the market. Kris Shepherd at GE Aerospace said the companies want to build out a high-power silicon carbide value chain. The bull case is showing up in more headlines. Wolfspeed Investor Relations
Wolfspeed said last week its fifth-generation silicon carbide MOSFETs can hit up to 27% higher efficiency than rival 1,200-volt options currently on the market. Dr. Cengiz Balkas, chief business officer, said engineers get “the most current possible” from a 5 mm by 5 mm silicon carbide chip. Wolfspeed Investor Relations
Wolfspeed’s jump outpaced other power-chip stocks. Onsemi gained $8.64 to $121.62, Navitas Semiconductor rose $1.64 to $24.02, and STMicroelectronics was up $4.98 to $78.39. The trading action puts Wolfspeed in the spotlight for reasons beyond just the sector, with the stock stuck between hopes for AI-driven demand and worries about dilution and its performance since bankruptcy.
But the downside risk hasn’t gone away. Wolfspeed reported $150.2 million in revenue for the quarter and a net loss of $119.9 million. Gross margin was negative, and the company had an $84 million operating cash outflow. It expects revenue of $140 million to $160 million in the fiscal fourth quarter and says gross margins will still be negative.
AI and power are the pitch, but buyers still have to pay up even with losses on the books and resale shares hanging over the stock. The market held its ground at Thursday’s close. The filing confirms supply is still there.
