Super Micro surges 15% on $60B order blitz; margin guidance raised to 15–17% on SpaceX XAI gigawatt build
Super Micro Computer stock jumped 15% in Tuesday trading after the server maker disclosed record momentum in fiscal Q4 (ended June 30, 2026). In a preliminary business update, the company reported gross margin and adjusted gross margin guidance of 15–17%, a sharp revision upward from the 8.2–8.4% range provided in May. The revision was driven by favorable customer and product mix, and the company disclosed receiving over $60 billion in new orders during the fourth fiscal quarter alone.
The order surge is directly tethered to infrastructure buildouts for training and inference at scale. CEO Charles Liang confirmed the company is co-building a gigawatt AI datacenter for SpaceX and XAI within a year—a project that requires thousands of custom server chassis, networking, and thermal systems. The backlog hit record levels at the end of FY2026, with customers' expected to receive the announced $60B in orders over future quarters, signaling multi-quarter revenue visibility into H2 2026 and beyond.
Rivals Dell and Hewlett Packard Enterprise rose in extended trading on the same update—Dell +5%, HPE +4%—as Street attention pivots to data center capacity constraints and the capital equipment cycle. For fiscal Q4, Super Micro now expects revenue to land at the low end of guidance ($11.0B–$12.5B), suggesting the margin beat reflects mix-shift, not volume outperformance.
The move underscores architecture capital's shift: GPU counts are no longer the binding constraint; cooling, power delivery, and interconnect fabric are. Super Micro's margin expansion on $60B+ order backlog signals customers' willingness to pay for integrated solutions rather than assemble components in-house, a secular tailwind for the ODM model in the AI infrastructure arms race.
