China says Nvidia violated anti-monopoly laws, significantly escalating trade tensions with US

China significantly escalated its trade standoff with the United States by announcing a preliminary antitrust finding against Nvidia, citing violations of its conditional approval for the Mellanox acquisition, which caused Nvidia's stock to drop 1.4% premarket. This aggressive action, taken amidst ongoing US-China trade talks and recent US efforts to control AI chip exports, signals potential rejection of a Trump administration deal allowing Nvidia to sell 'stripped-down' H20 chips to China. The move underscores the intensifying geopolitical competition over critical AI technology, which both nations deem essential for national security, further complicating market access for key providers like Nvidia, whose China sales constituted 13% of 2024 revenue.

Analysis

China's preliminary antitrust finding against Nvidia, citing violations related to the 2020 Mellanox acquisition, represents a significant escalation in the US-China technology trade war. The announcement, which prompted a 1.4% premarket drop in NVDA shares, coincides with high-stakes trade negotiations and appears to be a direct response to recent US actions, including placing Chinese chipmakers on the Entity List. This move casts considerable doubt on a recent deal brokered by the Trump administration that would permit Nvidia and AMD to export stripped-down AI chips, such as the H20, to China in exchange for 15% of the related revenue. With the Chinese market accounting for 13% of Nvidia's 2024 sales, this regulatory pressure introduces a new layer of risk beyond US export controls. The situation remains fluid as the Chinese investigation is ongoing, but the action signals Beijing's potential rejection of the US-led chip deal, complicating market access for a key revenue stream that may already be partially circumvented by black market channels.

Key Decisions for Investors

• Investors in Nvidia should closely monitor the Chinese antitrust investigation, as any definitive punitive action would directly threaten the 13% of revenue derived from China and likely trigger a downward revision of earnings forecasts.
• The viability of the US-brokered deal for limited AI chip exports to China is now in serious jeopardy, requiring a reassessment of growth assumptions for both Nvidia and AMD's China-related revenues.
• This event serves as a critical indicator of escalating geopolitical risk for all US tech firms with significant operations in China, suggesting that antitrust and regulatory tools are being increasingly weaponized in trade disputes.
