What if… China Blockades Taiwan

◇ Hypothetical scenario. What if… China Blockades Taiwan? The analysis positions INTC, LMT and RTX to benefit and TSM, AAPL and NVDA under pressure; confidence medium.

Hypothetical scenario — this analysis maps conditional exposure (“if this happens, who is exposed”). It is not graded against market prices unless the event occurs.

Analyzed 2026-08-25 — point-in-time, never revised. A hypothetical scenario is never graded.

Ranked exposures

1. ▼ TSM Taiwan Semiconductor Manufacturing Company Limited — impact -97 · confidence medium · horizon immediate
   A blockade would directly threaten TSMC's Taiwan fabs, workforce access, logistics, operations, exports, and customer deliveries of advanced chips.
2. ▲ INTC Intel Corporation — impact +90 · confidence low · horizon immediate
   As the primary US-based semiconductor manufacturer with leading-edge foundry ambitions, Intel would see massive demand shift away from TSMC.
3. ▼ AAPL Apple Inc. — impact -89 · confidence high · horizon immediate
   A Taiwan disruption would severely impair Apple's TSMC-based chip supply, Asian assembly and logistics, hardware availability, and regional consumer demand.
4. ▼ NVDA NVIDIA Corporation — impact -88 · confidence high · horizon immediate
   NVIDIA's heavy reliance on Taiwan-based advanced foundry and packaging capacity makes a blockade a severe, potentially immediate supply shock for AI and gaming chips.
5. ▼ AMD Advanced Micro Devices, Inc. — impact -85 · confidence high · horizon immediate
   AMD's CPUs, GPUs, and accelerators depend substantially on TSMC's advanced Taiwan fabrication, exposing its entire supply pipeline to an abrupt shutdown.
6. ▲ LMT Lockheed Martin Corporation — impact +82 · confidence high · horizon immediate
   A Taiwan blockade would drive urgent U.S. and allied procurement of missile defense, fighters, naval systems, and other Indo-Pacific deterrence capabilities, benefiting Lockheed Martin.
7. ▼ MRVL Marvell Technology, Inc. — impact -80 · confidence low · horizon weeks
   Fabless business model relies heavily on Taiwan foundries for producing custom data center, cloud, and carrier infrastructure chips.
8. ▲ RTX RTX Corporation — impact +80 · confidence high · horizon immediate
   An Indo-Pacific crisis would increase demand for Raytheon's naval defense, radar, air-defense, interceptor, precision-weapon, and sensor systems.
9. ▲ GFS GlobalFoundries Inc. — impact +80 · confidence low · horizon weeks
   Pure-play US-headquartered semiconductor foundry would experience an immediate surge in chip manufacturing orders seeking non-Taiwan capacity.
10. ▼ AVGO Broadcom Inc. — impact -77 · confidence high · horizon immediate
    Broadcom could face Taiwan-dependent manufacturing disruptions, shortages of custom AI and networking silicon, delayed customer shipments, and weaker Asian electronics demand.
11. ▼ QCOM QUALCOMM Incorporated — impact -75 · confidence high · horizon immediate
    Qualcomm faces major exposure to disrupted TSMC production, Taiwan-linked supply chains, and weaker Asian smartphone demand for its premium chipsets.
12. ▼ LRCX Lam Research Corporation — impact -75 · confidence low · horizon weeks
    A significant portion of wafer fab equipment revenue and servicing comes from Taiwan foundries and memory makers that would be inaccessible.
13. ▲ NOC Northrop Grumman Corporation — impact +70 · confidence high · horizon weeks
    A blockade would increase demand for Northrop Grumman's surveillance, command-and-control, unmanned maritime, long-range strike, stealth, and missile-defense platforms.
14. ▼ AMAT Applied Materials, Inc. — impact -69 · confidence medium · horizon weeks
    A blockade would halt Applied Materials' Taiwan equipment deliveries, installations, servicing, and fab-expansion spending, particularly affecting its major customer TSMC.
15. ▲ GD General Dynamics Corporation — impact +66 · confidence high · horizon weeks
    Expanded naval readiness and allied defense spending would boost demand for General Dynamics' submarines, ships, munitions, communications, and combat systems.
16. ▼ KLAC KLA Corporation — impact -65 · confidence medium · horizon weeks
    Trade embargoes and reduced Taiwan fab utilization would sharply delay KLA's semiconductor inspection, process-control, and yield-management equipment demand.
17. ▼ TSLA Tesla, Inc. — impact -65 · confidence low · horizon weeks
    Severe automotive chip shortages and immediate shipping and production bottlenecks throughout its Asian manufacturing and component footprint.
18. ▲ HII Huntington Ingalls Industries, Inc. — impact +64 · confidence high · horizon weeks
    A prolonged Taiwan crisis would accelerate U.S. naval construction, maintenance, fleet-capacity spending, and appropriations benefiting Huntington Ingalls' carrier and destroyer businesses.
19. ▲ TXN Texas Instruments Incorporated — impact +60 · confidence low · horizon quarters
    Possesses extensive internal US-based manufacturing capacity for analog and embedded processing chips, insulating it from Taiwan supply shocks.
20. ▼ MU Micron Technology, Inc. — impact -59 · confidence medium · horizon weeks
    Micron would face disrupted regional semiconductor supply chains, higher logistics costs, weaker electronics demand, and related pressure despite its non-Taiwan production.
21. ▼ WDC Western Digital Corporation — impact -59 · confidence low · horizon weeks
    Western Digital is exposed to Asian electronics manufacturing networks and would face supply-chain and end-market disruptions from a Taiwan crisis.
22. ▲ PLTR Palantir Technologies Inc. — impact +58 · confidence medium · horizon immediate
    Military escalation would increase demand for Palantir's defense intelligence, battlefield data integration, operational planning, artificial intelligence, and real-time situational-awareness software.
23. ▼ STX Seagate Technology Holdings plc — impact -56 · confidence low · horizon weeks
    Seagate's storage-device production and customer supply chain depend on Asian manufacturing and shipping routes vulnerable to blockade-related disruption.
24. ▼ HPQ HP Inc. — impact -54 · confidence low · horizon immediate
    HP's PC and printing hardware supply chains rely heavily on Taiwan-linked component ecosystems and Asian contract manufacturing.
