Ranked exposures

  1. ▼ NVDA Nvidia — impact -85 · confidence high · horizon quarters · 1st order
    Nvidia loses Azure accelerator demand and pricing power as Microsoft shifts inference workloads to proprietary Maia chips.
    Chain: Microsoft launches Maia inference accelerator in Azure → Azure shifts internal inference workloads to in-house silicon → Nvidia loses a top-three customer's accelerator volume → GPU pricing power and data center revenue growth slow
    What would break the call: Microsoft raises its Nvidia purchase commitments for training clusters while Maia stays limited to narrow internal workloads.
  2. ▲ MSFT Microsoft — impact +80 · confidence high · horizon quarters · 1st order
    Microsoft lowers Azure and Copilot inference costs by deploying proprietary Maia chips instead of purchasing Nvidia accelerators.
    Chain: Microsoft deploys proprietary Maia accelerators across Azure → cost per inference token falls versus merchant GPUs → Copilot and Azure AI gross margin improves → capital spending mix shifts away from vendor markup
    What would break the call: Maia yields or software maturity disappoint, forcing Microsoft to keep buying Nvidia systems at prior volumes.
  3. ▲ AVGO Broadcom — impact +66 · confidence low · horizon quarters · 2nd order
