Key Highlights
- Treasury Secretary Scott Bessent has pressed Commerce Secretary Howard Lutnick over delays in blacklisting Megaspeed, which is accused of rerouting advanced Nvidia chips to China.
- U.S. export controls on Nvidia’s A100 and H100 processors began in August 2022 and have since expanded to newer models and China-specific variants.
- Estimates indicate that between 1 million and 1.2 million H100-equivalent chips had been smuggled into China by mid-2026, highlighting major enforcement challenges.
Bessent-Lutnick Dispute Highlights Nvidia Chip Export-Control Tensions
Treasury Secretary Scott Bessent’s position does not amount to a permanent call to shut China out of advanced Nvidia chips. Bessent has indicated some flexibility toward allowing older Nvidia processors into China as they lose their technological advantage.
That position came into sharper focus in November 2026, when Bessent confronted Commerce Secretary Howard Lutnick over delays in blacklisting Megaspeed. The company has been accused of rerouting advanced Nvidia chips to China. Estimates place the suspected flow at hundreds of thousands of H100-equivalent units, with a value in the billions of dollars.
Cabinet secretaries do not usually make their disagreements over entity-list decisions public. Bessent’s pressure on Lutnick over the enforcement timeline suggests that the dispute has moved beyond routine administrative processing and into a broader debate over how aggressively the United States should enforce restrictions on Nvidia’s artificial-intelligence chips.
The episode also reflects intelligence concerns involving Nvidia’s leadership and alleged connections to companies such as Megaspeed. Those connections remain allegations, but they have increased pressure in an already sensitive area of U.S. technology and national-security policy.
How U.S. Controls on Nvidia Chips Developed
U.S. export controls targeting Nvidia chips began in August 2022. The initial measures focused on the A100 and H100, cutting China off from the company’s most capable AI processors at the time.
Since then, Washington’s rules have become more complex. The United States introduced case-by-case licensing reviews for newer models, beginning with the H200. Nvidia also introduced China-specific chip variants from January 2026 that were designed to remain below regulatory thresholds.
Nvidia’s Blackwell chips continued to face strict export controls as of late 2025. However, restrictions on paper have not prevented advanced processors from reaching China through indirect channels. By mid-2026, estimates suggested that between 1 million and 1.2 million H100-equivalent chips had been smuggled into the country.
The Trump administration has sought to close those gaps. President Trump approved crackdowns on chip diversion in May, August, and November 2026, but implementation has faced resistance both within the U.S. government and outside it.
What the Megaspeed Dispute Means
The conflict between Scott Bessent and Howard Lutnick demonstrates that the disagreement over export controls is not merely theoretical. The Treasury Department appears focused on closing enforcement gaps quickly, while the Commerce Department, which is responsible for blacklisting companies, has moved more slowly on Megaspeed.
The next key question is whether Megaspeed is added to the U.S. blacklist and how quickly that decision is made. A prolonged delay would indicate that commercial considerations continue to influence Commerce Department decisions involving sensitive technology restrictions.
The future export ceiling is another issue to watch. Bessent’s willingness to consider older chips suggests that the H100 threshold may not be permanent. If Washington eventually permits H100-class hardware to move more freely, the next policy dispute could center on the H200 and more advanced processors.
Why This Matters
The estimated movement of 1 million to 1.2 million H100-equivalent chips into China indicates that the central problem is not simply whether the United States has rules in place. The larger challenge is enforcement: tracing chips through shipping routes, shell companies, and third countries while determining which companies should face restrictions.
The Megaspeed case also shows how export-control policy can create tensions across the U.S. government. Treasury pressure for faster enforcement, Commerce Department decisions on blacklisting, and concerns about the commercial impact of restrictions are converging around Nvidia’s advanced AI hardware and China’s access to it.
Frequently Asked Questions
What is Megaspeed accused of doing?
Megaspeed is accused of rerouting advanced Nvidia chips to China. Estimates suggest that the suspected volume involved hundreds of thousands of H100-equivalent units valued in the billions of dollars.
When did U.S. export controls on Nvidia chips begin?
The first U.S. export controls targeting Nvidia’s A100 and H100 processors began in August 2022.
What is the main enforcement challenge?
The main challenge is tracking chips through shipping routes, shell companies, and third countries. Estimates of 1 million to 1.2 million H100-equivalent chips reaching China by mid-2026 suggest that existing rules have not fully stopped the flow.
