China Probes Nvidia for Anti-Monopoly Violations Amid Rising Tech Tensions

China’s market regulator announced on Monday that its preliminary investigation found Nvidia in violation of the country’s anti-monopoly law. The statement, issued by the State Administration for Market Regulation (SAMR), did not specify the details of the alleged violations. However, it marks the latest setback for the U.S. chip giant, which has become a central player in the global artificial intelligence (AI) chip market.

SAMR had opened the probe in December 2024, saying the company was suspected of breaching antitrust rules. Analysts viewed the move as a retaliatory response to Washington’s restrictions on advanced chip exports to China.

Nvidia Under Scrutiny Over Mellanox Deal Commitments

The Chinese regulator said Nvidia may have failed to honour commitments made during its 2020 acquisition of Israeli chip designer Mellanox Technologies. At that time, Beijing granted conditional approval for the $6.9 billion deal, imposing requirements to ensure fair competition in China.

SAMR stated it would continue its investigation but offered no timeline for its conclusion. Nvidia has yet to respond publicly to the regulator’s announcement.

Heavy Fines Possible Under Chinese Law

China’s anti-monopoly law allows fines ranging from 1% to 10% of a company’s previous year’s revenue. According to Nvidia’s latest annual report, China generated $17 billion in revenue for the firm during the fiscal year ending January 26, 2025—about 13% of its global sales. This exposure puts the company at risk of significant financial penalties if SAMR upholds the violations.

Shares of Nvidia fell about 2% in pre-market trading on Monday following the news. Market watchers said the probe adds a new layer of uncertainty for the chipmaker already grappling with U.S.-China tech tensions.

Trade Talks Cast a Shadow Over Chip War

The regulator’s announcement coincides with trade discussions between the U.S. and China in Madrid, where semiconductors are expected to be a key agenda item. Access to cutting-edge AI chips such as those made by Nvidia has emerged as one of the biggest flashpoints in the race for technological dominance between the two nations.

While Washington has tightened export controls on advanced chips, Beijing has accelerated efforts to reduce reliance on U.S. technology. The Chinese government has summoned domestic firms—including Tencent and ByteDance—to explain their purchases of Nvidia’s H20 chip. Authorities expressed concerns over information risks tied to the U.S.-designed product.

Security Questions Over Nvidia’s China-Tailored Chips

Last month, China’s Cyberspace Administration summoned Nvidia representatives to answer questions about whether the H20 chip posed potential backdoor security risks to Chinese data and privacy. The H20 was designed to comply with U.S. export restrictions while still serving the Chinese market.

Industry analysts say the investigation reflects China’s dual strategy: maintaining leverage over U.S. firms operating domestically while building up its own chip ecosystem. For Nvidia, this means balancing compliance with U.S. export rules and China’s regulatory demands without losing a market that has long been one of its most lucrative.

Nvidia at the Center of U.S.-China Tech Rivalry

As the world’s leading producer of AI chips, Nvidia has seen its fortunes soar with the rise of generative AI. But the same dominance that drives its profits has made it a political and regulatory target. Under former U.S. President Donald Trump and continuing into the current administration, Washington imposed—and later partially eased—restrictions on the sale of high-performance chips to China.

Now, China’s investigation signals that the contest over technology supremacy is far from over. If SAMR ultimately imposes a fine or further conditions on Nvidia, the decision could reshape how U.S. tech companies operate in the Chinese market.

What Lies Ahead

With investigations ongoing, Nvidia faces an uncertain road in its second-largest market. Its response to SAMR’s findings will be closely watched by investors, industry players, and governments on both sides of the Pacific. Analysts say the probe underscores how intertwined global tech supply chains have become—and how quickly they can be disrupted by geopolitics.

For now, Nvidia stands at the center of a high-stakes battle between the world’s two largest economies, with the outcome likely to influence the next phase of the global AI and semiconductor race.
