Nvidia's Declining Dominance in China and the Rise of Cambricon: Strategic Asset Reallocation in the AI Semiconductor Sector

The AI semiconductor sector is undergoing a seismic shift in China, driven by geopolitical tensions, U.S. export restrictions, and a strategic pivot toward domestic self-sufficiency. For investors, this reallocation of capital and market share between global giants like Nvidia and emerging local champions like Cambricon represents a critical inflection point.

The Erosion of Nvidia’s Market Position

Nvidia, once the uncontested leader in AI chips, has seen its dominance in China erode rapidly. In 2024, it held a 66% share of the Chinese AI semiconductor market [4], but by mid-2025, U.S. export bans on advanced chips like the H20 have crippled its ability to serve this critical market [2]. The H20, a key product for AI training and inference, was previously a cornerstone of Nvidia’s revenue in China. With its sale now restricted, the company’s Q2 2025 earnings from the region remain unreported, while its global revenue hit $46.7 billion—a stark contrast to the explosive growth of local rivals [2].

Cambricon’s Meteoric Rise

Cambricon, often dubbed “China’s little Nvidia,” has capitalized on this vacuum with a 4,300% year-on-year revenue surge in H1 2025, reaching 2.88 billion yuan ($402.7 million) [1]. This growth is not merely a function of market share capture but a reflection of strategic alignment with Beijing’s push for technological sovereignty. The Chinese government’s emphasis on reducing reliance on foreign tech—coupled with nationalist sentiment stoked by U.S. rhetoric—has accelerated adoption of Cambricon’s Siyuan 590 AI chip, a direct competitor to Nvidia’s A100 [5].

Cambricon’s profitability has also turned a corner, posting a record net profit of 1.04 billion yuan in H1 2025, reversing a 530 million yuan loss in the same period in 2024 [3]. This turnaround is fueled by improved software compatibility, including tools that ease migration from Nvidia’s CUDA ecosystem [4], and a growing client base among Chinese tech giants.

Strategic Implications for Investors

The reallocation of assets in this sector is reshaping investment dynamics. While Cambricon’s market capitalization has surged to $80 billion [1], it still lags behind Nvidia’s $46.7 billion Q2 revenue. However, the gap is narrowing as China’s AI infrastructure increasingly prioritizes domestic solutions. For investors, this trend underscores the importance of hedging against geopolitical risks by diversifying exposure to both global leaders and regional innovators.

Cambricon’s rise is not without challenges. It remains constrained by U.S. export controls that limit access to advanced manufacturing tools and design software [3]. Additionally, competition from Huawei and other Chinese firms is intensifying [2]. Yet, its rapid innovation in software ecosystems and partnerships with state-backed entities position it as a long-term contender.

Conclusion

The AI semiconductor sector in China is a microcosm of broader geopolitical and economic shifts. For investors, the decline of Nvidia’s dominance and the ascent of Cambricon highlight the necessity of strategic asset reallocation. While Nvidia’s global leadership in AI remains intact, its China-specific vulnerabilities create opportunities for local players to redefine the market. As Beijing’s self-sufficiency agenda gains momentum, the sector will likely see further consolidation and innovation, rewarding those who adapt to the new paradigm.
