Wolfspeed's $1.5B Pentagon Loan and Silicon Carbide AI Power

On October 7, 2026, Wolfspeed announced a conditional commitment from the US Department of War's Office of Strategic Capital (OSC) for a loan of up to $1.5 billion. The company makes silicon carbide (SiC) chips and materials, and it emerged from Chapter 11 bankruptcy only a year earlier. As Bloomberg reported, the government would also receive warrants to buy equity. The deal sits at the meeting point of three storylines: AI data center power, defense supply chains and the growing US habit of taking ownership positions in strategic companies.

What the Wolfspeed OSC loan actually says

The terms below come from Wolfspeed's Form 8-K press release, the primary source.

• Size and structure: up to $1.5 billion in a senior secured delayed-draw term loan facility, meaning money is drawn in tranches rather than all at once.
• Tenor: 30 years.
• Warrants: VWAP-based warrants for up to 7.5% of Wolfspeed's fully diluted equity, issuable pro rata as financing tranches are funded. VWAP is the volume-weighted average price, so the exercise price floats with the market rather than being fixed today.
• Not final: the release lists substantial due diligence, definitive agreements, government approvals and appropriations, third-party consents, amendments or waivers to certain existing debt, and compliance with expected covenants. It states there is no assurance the financing will be provided.
• Not disclosed: the interest rate.

The company says the money would support domestic silicon carbide materials and power devices, onshore low-voltage and high-voltage gallium nitride (GaN) power devices, GaN-on-SiC radio-frequency wafers, radiation-hardening capability, and GaN epitaxy for communications and electronic warfare systems. Its footprint is in North Carolina, New York and Arkansas.

Reuters, as carried by a local radio syndication, reported Wolfspeed shares rose 27% in extended trading.

What silicon carbide is and why it matters

Silicon carbide is a compound semiconductor used for power electronics, the chips that switch and convert electricity rather than process data. Its bandgap, the energy needed to make it conduct, is about 3.26 eV against 1.12 eV for silicon, according to an engineering explainer roundup. A wider bandgap lets a device withstand a much stronger electric field, so it can be thinner, lose less energy as heat and switch faster. Those figures are textbook-level and consistent across trade sources, but real efficiency gains vary by design, as the next section shows.

The trade-off is cost. SiC wafers are harder to grow and cut than silicon, so SiC tends to be used where voltage and efficiency justify the price.

Three markets pulling on the same material

EVs. SiC inverters help cut losses in the drivetrain, and the advantage grows at higher voltage. One analysis from a patent-research vendor puts drive-cycle efficiency gains over silicon IGBTs at roughly 3 to 5 percent, an indicative estimate rather than a benchmark. Weaker EV demand was one of the pressures Wolfspeed cited when it filed for bankruptcy.

AI data centers. This is the newer pull. Nvidia says in a developer blog that it is moving data center power to 800 VDC to support 1 MW racks and beyond, starting in 2027. Today's racks use 54 VDC distribution, and Nvidia argues that at megawatt scale power shelves would consume up to 64 U of rack space, leaving no room for compute. Higher voltage means lower current for the same power, which shrinks copper and conversion hardware. Its partner list includes Infineon, onsemi, STMicroelectronics, Navitas and Renesas, and Navitas said its GaN and SiC technologies were selected for the design. The 2027 timing dates from May 2025, and we did not verify whether it has changed.

Wolfspeed's own link is indirect. On August 6, 2026, it announced a partnership with LITEON, qualifying its SiC for LITEON's 800 VDC power sidecar and rack power supply platforms aimed at hyperscalers. We found no direct Nvidia supply agreement with Wolfspeed, and no source on how much of its revenue comes from Nvidia-linked designs.

Defense. The stated uses include radiation-hardened parts, GaN-on-SiC RF wafers and electronic warfare electronics. These are applications where the government has reasons to want a domestic source, which is the logic the OSC deal rests on.

Wolfspeed's road to October 2026

Founded in 1987 as Cree, Wolfspeed built its business on SiC and bet heavily on 200mm wafer production. In October 2024 it signed a non-binding preliminary memorandum with Commerce for up to $750 million of CHIPS Act funding, with Commerce saying the company needed to strengthen its balance sheet. We found no source confirming that award was ever finalized or formally terminated.

On June 22, 2025, it signed a restructuring support agreement, and it filed prepackaged Chapter 11 petitions on June 30, 2025. It cited production delays at its New York factory, Chinese competition, weaker EV demand and mounting debt. Reports put its emergence around September 29, 2025, with total debt cut by about 70% (reported as roughly $6.75 billion down to $2.12 billion), maturities extended to 2030 and cash interest down about 60%, per Financier Worldwide. Sources differ slightly on exact dates, so check the court docket for precision.

The OSC and the government-equity trend

The Office of Strategic Capital makes loans and loan guarantees to firms in critical technologies. It was created under the Biden administration and written into law in the fiscal 2024 NDAA. DefenseScoop reports that it covers 31 technology categories, including microelectronics, and that the fiscal 2027 request for the program it oversees is about $20.2 billion, more than ten times the current allotment. Its earlier headline deal was a $150 million loan to MP Materials for heavy rare earth separation.

Wolfspeed fits a pattern of public money arriving with an ownership stake attached:

• Intel (August 2025): the government took a 9.9% stake, 433.3 million shares at $20.47 for $8.9 billion, funded by converting previously awarded CHIPS and Secure Enclave money, per Yahoo Finance. Intel also reported a larger stock offering in 2026.
• MP Materials (July 2025): a $400 million Pentagon purchase of preferred shares for roughly 15%, with warrants, plus the OSC loan and a price floor.
• OpenAI: reported discussions, not a completed deal, about a roughly 5% US government stake, covered in our earlier analysis.

The structures differ. Intel and MP involved direct share purchases, while Wolfspeed's would be debt plus warrants, so the government is paid back with interest if the company succeeds and shares in upside through the warrants.

What to watch

• Conversion to a final deal: whether definitive agreements, approvals and appropriations arrive, and what the interest rate and covenants turn out to be.
• Draw schedule: warrants vest as tranches are funded, so the pace of drawdowns determines dilution.
• Demand proof: whether 800 VDC deployments in 2027 translate into SiC volume for Wolfspeed rather than competitors such as Infineon and STMicroelectronics.
• Policy durability: OSC funding depends on appropriations and is subject to congressional oversight.

AI infrastructure is increasingly constrained by electricity, not just chips, which is one reason model-agnostic tools such as Metir that let teams switch models as costs and capabilities shift can be useful while the physical stack catches up.
