The US Commerce Department determines which foreign buyers can access America's most advanced AI chips. At present, the department's own chief appears to be the one applying the brakes.

Commerce Secretary Howard Lutnick held back a package of curbs that President Donald Trump had floated on sales of Nvidia hardware into China, following a round of discussions in the Oval Office, according to a CryptoBriefing report published on November 11, 2026. The pause comes as Nvidia's market value has shed an estimated $700 billion as of mid-November 2026, with investors watching the export fight closely. The episode underscores a widening clash inside the administration over export controls, a Singapore-based chip buyer, and a blacklist that has been effectively frozen for more than a year.

A classified memo, a Singapore buyer, and a frozen blacklist

The decision did not happen in isolation. According to the report, Lutnick has faced significant pushback inside the administration over his handling of export controls on Nvidia's AI chips.

Before Trump's trip to China on May 13–15, 2026, Lutnick reportedly received a classified memo concerning Nvidia CEO Jensen Huang's ties to Alice Huang, a former executive linked to potential Chinese espionage.

Then there is Megaspeed. The Singapore-based company is an Nvidia customer accused of funneling billions of dollars' worth of chips into China. Megaspeed has reportedly bought more than $4.8 billion in Nvidia chips since mid-2024, and purchases on that scale have raised red flags over whether US export laws are being followed.

On November 5–6, 2026, Treasury Secretary Scott Bessent confronted Lutnick in a Situation Room meeting about why Megaspeed had not been placed on the Entity List. The Entity List is the Commerce Department's trade blacklist, and landing on it sharply restricts a foreign company's ability to receive sensitive US technology. Since October 2025, the department has not added a single new name to it, even though multiple applications have been under review.

Pressure building from Congress

The friction extends well beyond the cabinet. Democratic lawmakers are pushing for tighter limits on advanced AI chip exports, and they have set a deadline: Lutnick has until December 1, 2026, to provide accountability on the issue. Bessent's challenge in the Situation Room underscored frustrations that had already been building on Capitol Hill.

What it means for Nvidia and the chip sector

For Nvidia shareholders, the estimated $700 billion drop in market value is the clearest scoreboard. It reflects concerns over US-China trade relations and over how chip exports to China are being policed.

Several markers are worth tracking from here:

• The December 1 deadline. How Lutnick responds to the Democratic lawmakers will show whether congressional pressure can move the department.
• The Entity List. The first addition since October 2025 would be a meaningful signal. If Megaspeed is the name added, it would suggest Bessent's push landed.
• Trump's proposed curbs. Lutnick stalled them, but stalled is not the same as killed.
• The Huang memo. The reported classified warning about Jensen Huang's links to Alice Huang adds a layer of scrutiny around Nvidia's leadership.

For now, US chip-export policy toward China looks less like a single strategy and more like a negotiation among the people writing it. Commerce is holding back, Treasury is pushing, and Congress has circled a date on the calendar.
