Looking at the list of the top 20 fastest-growing AI infrastructure companies, a few names really stand out.
$Lumentum(LITE)$ (Lumentum) is up 56%, $Applied Optoelectronics(AAOI)$ (Applied Optoelectronics) is up 111%, $SanDisk Corp.(SNDK)$ (Sandisk) is up 110%, $IREN Ltd(IREN)$ is up 95%, and $SUPER MICRO COMPUTER INC(SMCI)$ (Super Micro Computer) is up 82%.
This list shows the AI era is about much more than just GPU chips. Optical fabrics and ultra-fast storage are the real unsung heroes.
The massive growth of AAOI (111%) and LITE (56%) highlights the sheer desperation for high-speed optical components to prevent bandwidth bottlenecks. Meanwhile, the freshly independent memory giant SNDK, pulling in 110% growth—especially after its official inclusion in the Nasdaq-100 index this April—proves that enterprise SSDs are breaking massive AI training bottlenecks. Add in the power play IREN (95%) and a stabilizing liquid-cooling leader SMCI (82%), and you have an incredibly solid infrastructure thesis.
During this macro pullback, hard assets backed by secured megawatts and concrete backlogs are bound to hold up much better than pure speculative beta.
