Astera Labs
ALABcompute· NASDAQAstera Labs, connectivity silicon: PCIe and CXL retimers, smart cable modules, and fabric switches that move data inside and between AI servers.
Why it matters
As accelerators multiply, getting data between them without bottlenecking is its own constraint. Astera sells the connectivity (retimers, fabric) that scales GPU systems, a pure play on the interconnect problem.
The read
Levered to Connectivity inside the rack: moving data between multiplying accelerators without bottlenecking is its own constraint.
Bull case: A pure play on the interconnect problem: connectivity content per system rises with every GPU-count and speed increase, and design-ins compound.
