Market move
Wolfspeed shares surged +12.9% in pre-open trading after the company revealed it had signed a Memorandum of Understanding with GE Aerospace, a deal announced on June 8 intended to accelerate adoption of high-voltage silicon carbide in industrial, aerospace, and defense markets. The MOU specifically covers Wolfspeed's 10 kV MOSFET die supply and a joint effort to develop standard high-voltage SiC power module formats.
Why the partnership matters
The arrangement is notable because it stretches Wolfspeed's commercial reach into aerospace and defense, sectors that typically command higher margins, and thereby provides further diversification away from the electric vehicle market where demand has been softer. The GE Aerospace MOU positions aerospace and defense as an additional market vector alongside Wolfspeed's existing opportunities.
Momentum behind the stock
The GE Aerospace announcement comes on top of an extended period of positive momentum around Wolfspeed. A bullish note from Citrini Research characterized Wolfspeed as a beneficiary of the AI infrastructure re-rating and argued that the company's silicon carbide fabs are strategic, scarce assets unlikely to be quickly replicated by competitors. Wolfspeed has also introduced two new 3.3 kV silicon carbide power module families aimed at AI data centers and energy-transition infrastructure, formed a dedicated data center solutions team, and opened a regional office in the San Francisco Bay Area to engage more closely with hyperscalers and ecosystem partners.
Short interest and potential amplification
Short interest in Wolfspeed stands at 16.1 million shares, representing 33.4% of the float. With that level of short exposure, any positive catalyst can be amplified by short-covering activity, which helps explain the magnitude of the pre-market move following the GE Aerospace disclosure.
Broader market backdrop
The pre-market rally in Wolfspeed is occurring against a weak broader market environment. The S&P 500 is declining 2.6%, the Dow Jones is off 1.4%, and the NASDAQ is falling 4.2%, with AI-related semiconductor names generally under pressure. The S&P 500 is described in market commentary as seeing a significant wipeout while the Nasdaq records its biggest point drop on record, amid tumbling AI stocks and rising Fed rate-hike odds. The strength in Wolfspeed despite these headwinds highlights how specific the GE Aerospace catalyst is to the company.
Revenue and market vectors
Wolfspeed reported that AI datacenter revenue grew 30% sequentially in its most recent quarter. The GE Aerospace MOU brings aerospace and defense into the company's portfolio as a third major growth vector, joining data centers and renewables, and reinforcing the investment thesis that Wolfspeed's silicon carbide technology is addressing multiple large end markets at once.
Implications
The combination of a blue-chip strategic partner, an AI infrastructure re-rating thesis, and elevated short interest has created conditions conducive to the sharp upside move experienced in pre-market trading. The GE Aerospace MOU, product launches targeting high-voltage applications, and the company's regional presence to work with hyperscalers collectively underpin the recent investor enthusiasm.
