Wolfspeed Is Down 25% in October: Stay the Course, or Just Stay Away?

October opened with federal support for Wolfspeed (NYSE:WOLF | WOLF Price Prediction), but the silicon carbide maker is ending the month lower. Wolfspeed stock is down 25% in October to $21.02 in late trading, after closing at $28.13 on September 30. That slide includes a 16% drop from the prior close. The decline shows how volatile the stock has been since the company emerged from bankruptcy protection on September 29, 2025.

At its core, Wolfspeed makes silicon carbide substrates and wafers, plus power chips used in electric vehicles, industrial equipment, artificial intelligence (AI) data centers and renewable energy. Larger power chipmakers fell this month too, though by less. ON Semiconductor (NASDAQ:ON) stock is down 8% over the past month to $69.97. Over the same stretch, STMicroelectronics (NYSE:STM) stock is down 14% to $45.69.

Bull Case: Washington and Infineon Line Up Behind Wolfspeed

For Wolfspeed, the bull case starts in Washington. On October 7, Wolfspeed said it had received a conditional commitment from the U.S. Department of War’s Office of Strategic Capital for up to $1.5 billion in long-term financing to support domestic silicon carbide production. That commitment is part of a wider federal push. The department’s fiscal 2027 budget request puts more than $100 billion toward defense supply chains, and the Office of Strategic Capital is among the programs it funds.

Government support could also help Wolfspeed win customers who are considering long-term supply contracts. Wolfspeed and Infineon expanded their wafer supply agreement on October 15, adding 200-millimeter wafers to the existing 150-millimeter supply. The deal fits Wolfspeed’s own shift, since the company closed its Durham 150mm device fab and moved production to its 200mm Mohawk Valley fab.

Wolfspeed’s data center business gives bulls another reason for optimism. The company’s AI data center revenue more than doubled in fiscal 2026 and grew approximately 20% from the prior quarter in Q4 FY2026. As supply chains move toward U.S. producers, a domestic source of a strategic material could become more valuable to Wolfspeed customers.

Bear Case: Fine Print, Dilution and Deep Losses at Wolfspeed

For Wolfspeed skeptics, the fine print comes first. Wolfspeed’s commitment letter still needs definitive agreements, due diligence, government approvals and appropriations, and the company warned that there’s no guarantee any funding will be provided. If the money flows, Wolfspeed would issue the government warrants for up to 7.5% of its fully diluted equity as each tranche is funded. A warrant is the right to buy stock at a set price. When those new shares are created, each existing share represents a smaller stake in the company, which is what dilution means.

Wolfspeed’s fundamentals are the bigger hurdle. On August 19, the company reported Q4 FY2026 revenue of $149.6 million, down 24.1% year over year, with an adjusted gross margin of negative 20%. Chief Financial Officer Gregor Van Issum estimated that gross margin breaks even at “an $800 million annual run rate,” and Wolfspeed expects its adjusted gross margin to stay negative in Q1 FY2027.

Paying for an expensive domestic factory build after the restructuring is still Wolfspeed’s job, and Van Issum noted that its first-lien debt carries “around 16% interest.” Competition adds pressure, because larger and more diversified chipmakers also sell silicon carbide. Susquehanna has kept a Hold rating on Wolfspeed with a $25 price target.

How Wolfspeed’s Pure-Play Model Differs From Larger Rivals

Wolfspeed is a silicon carbide specialist that makes its own substrates and builds its chips on them, so its results depend on one material. ON Semiconductor sells a much broader range of power and sensing chips, and silicon carbide is just one product line.

STMicroelectronics sells microcontrollers, analog chips and power products to auto and industrial customers, so it has more ways to absorb weakness in any single market. Owning the whole process gives Wolfspeed more upside if silicon carbide demand speeds up, and less protection if it doesn’t.

Wolfspeed’s Next Tests and Who Each Path Fits

The next test for Wolfspeed is its upcoming earnings report, which will show whether data center growth can make up for weaker automotive demand. Another milestone for Wolfspeed is the signing of definitive loan agreements. Readers can also watch for signs of customer demand for silicon carbide, including customers qualifying Wolfspeed’s 200-millimeter wafers.

For WOLF stock investors with a long time horizon and a high tolerance for price swings, the federal support and growing data center business are the key points in the bull case. For savers who need stable capital, a key milestone is evidence that the company can reach positive gross margins. Turnarounds after a restructuring can move sharply in either direction, so how much money is at stake matters as much as the decision itself. For traders, the resolution of Wolfspeed’s federal loan question is a key catalyst to monitor.
