IBM supply chain risk

As of 2026-09-05, IBM depends on 6 tracked suppliers headquartered in 2 countries (4 of them in the United States). 5 of those suppliers hold a monopoly or leader position in their own segment, led by NVIDIA, TSMC and Broadcom. IBM itself carries a supply-chain criticality score of 68/100, with 235 tracked companies downstream of it.

Data as of 2026-09-05 · suppliers are the curated key_supplier edges in the wafergraph dataset (researched or segment-inferred — see /methodology) · criticality is the graph-derived chokepoint score, 0–100

Dominant and single-source suppliers

  • NVIDIA — leader in GPU & AI Accelerators, United States criticality 81/100
  • TSMC — leader in Pure-Play Foundry, Taiwan criticality 81/100
  • Broadcom — leader in Networking Silicon, United States criticality 81/100
  • CoreWeave — leader in GPU Clouds (Neoclouds), United States criticality 81/100
  • ASPEED Technology — leader in Edge & IoT SoC, Taiwan criticality 81/100

A monopoly or leader supplier is the hardest to replace. These are the edges to watch first.
