Supermicro Stock Soars 24% as Margin Guidance and a Record $60B Backlog Reignite the AI Trade

Supermicro (SMCI) shares rocketed roughly 24% in early Wednesday trading after the AI server maker told investors it expects its gross margins to nearly double while it works through a record order backlog. The move immediately pushed SMCI to the top of the day’s most-active and trending lists.
What Sparked the Rally
The catalyst landed after Tuesday’s closing bell. In a business update, Supermicro said it now expects gross margins between 15% and 17% — a dramatic jump from its prior guidance of just 8.2% to 8.4%. Management credited the improvement to “a favorable customer and product mix,” and investors wasted no time rewarding the sharply better profitability outlook.
A Record-Breaking Backlog
Just as importantly, Supermicro revealed that demand is piling up faster than ever. The company reported that total new orders topped $60 billion during the fourth quarter of fiscal 2026, driving its backlog to record levels. As a result, the guidance raise looks less like a one-off and more like the early payoff from a surging pipeline of AI infrastructure orders.
Powering the AI Buildout
To understand why the numbers matter, it helps to know what Supermicro actually builds. The company designs servers and data center systems packed with chips from Nvidia (NVDA), Intel (INTC), and AMD (AMD) — placing it squarely at the center of the AI hardware boom. Underscoring that positioning, CEO Charles Liang recently said the company is co-building “another new Gigawatt AI datacenter” for SpaceX and xAI within the year.
A Volatile Road to Get Here
Even so, the path hasn’t been smooth. Despite the broader AI tailwind, SMCI shares still sit down nearly 13% year to date. The stock tumbled back in June after the company announced an equity raise to buy components for roughly $39 billion in AI server orders. Consequently, Wednesday’s surge marks a sharp reversal in sentiment rather than a straight-line climb.
The Bottom Line
Ultimately, Supermicro’s guidance raise reframes the story for investors. A margin outlook that nearly doubles, paired with a record $60 billion in fresh orders, signals that the company is converting AI demand into real profitability. If Supermicro can execute against that backlog, this morning’s rally may prove to be more than a one-day pop.
