Power semiconductor stocks are pushing higher in Monday trading, with Wolfspeed (NYSE:WOLF) up 5.74% to $33.61, STMicroelectronics (NYSE:STM) up 4.17% to $56.56, and ON Semiconductor (NASDAQ:ON) up 2.96% to $85.11. The move follows a weekend Mizuho research note flagging a stronger and faster NVIDIA Vera Rubin ramp than the market had been positioned for.
Vera Rubin Ramp Signals Reset the Power Semi Setup
Mizuho, in a note published Sunday, August 16, 2026, told clients to expect strong VR200 NVL72 ramps in 2027, ramping in Q4 2026 led by xAI and Meta, with NVIDIA potentially pushing the four-die transition out to Feynman and running VR-Ultra on a two-die configuration. The firm also flagged 2027 CoWoS growing more than 75% with NVIDIA and Broadcom and cloud service provider RPO/backlog now at $2.3 trillion, up 3.5x year over year.
Mizuho’s named upside list covers Dell, Credo, NVIDIA, Broadcom and Lumentum, while the three power names moving here benefit indirectly. The connection is a read-through: Vera Rubin materially raises power management content per rack, so a bigger, on-schedule VR200 ramp means more power semiconductor content shipped across the rack, alongside more GPUs. Just as important, weeks of chatter about a Vera Rubin delay had weighed on the group. A supply chain check pointing to xAI and Meta anchoring a Q4 2026 ramp removes that overhang, and the removal is itself the catalyst.

Content Per Rack Is the Story
ON Semiconductor has been the loudest voice on this. Management said content per rack goes from $15,000 per rack today toward $115,000 per rack under 800V DC architecture, with AI data center revenue expected to more than double in 2026 and silicon carbide in data center applications projected to grow nearly 60% year-over-year. CEO Hassane El-Khoury framed the company as “the only broad-based U.S. power semiconductor supplier with technologies spanning the full AI power tree.”
