Super Micro Computer, Inc. (NASDAQ:SMCI) is one of the fastest-growing AI infrastructure stocks to buy. On June 11, 2026, Supermicro priced equity and equity-linked financing transactions that, together with a planned at-the-market program, represented a total potential equity raise of $7.0 billion. Super Micro Computer said the capital would help fund component purchases tied to roughly $39 billion of advanced AI server orders received in recent weeks from more than 20 customers, including orders for its Data Center Building Block Solutions.

That order base underscores Supermicro’s position in rack-scale AI infrastructure, where server demand is expanding quickly but also requires heavy working-capital support. The same dynamic was visible in fiscal Q3 2026, when net sales rose to $10.2 billion from $4.6 billion a year earlier, while cash used in operations reached $6.6 billion and total bank debt plus convertible notes stood at $8.8 billion.

Super Micro Computer, Inc. (NASDAQ:SMCI) provides application-optimized servers, AI systems, storage, networking, liquid-cooling infrastructure, software, and support services for enterprise, cloud, data-center, 5G, edge, and embedded markets.
