OK I looked up and these seem to be the monthly reporting companies. Intel and AMD got out some years ago, but it seems they are somehow included in chip sales statistics that SIA then reports.

Somehow INTEL, AMD and NVIDIA sales get included it seems, so there is some "double-counting" somewhere perhaps?
Product Classification: NVIDIA's AI accelerators and GPUs are categorized under
Logic chips, which the SIA noted as the largest product category in 2025, reaching over $301 billion.
Market Influence: Recent SIA reports highlight that the "NVIDIA-led boom" in AI infrastructure is a primary driver behind global semiconductor sales nearing the
$1 trillion milestone projected for 2026.
Industry Representation: The SIA represents approximately 99% of the U.S. semiconductor industry by revenue; as a leading U.S. chip designer, NVIDIA's performance is central to the
SIA’s State of the Industry reports.
Executive Involvement: NVIDIA's founder and CEO,
Jensen Huang, has been recognized with the SIA’s highest honor, the
Robert N. Noyce Award, further cementing the company's role within the association.
Broadcom:
While the SIA focuses on its
Semiconductor Solutions revenue (which hit new highs in 2025 due to AI networking demand), it typically excludes Broadcom's non-semiconductor segments, such as its
Infrastructure Software (e.g., VMware).
