Analyst: Musk-Trump feud a major twist in Tesla’s stock market story

US President Donald Trump confirmed after the close on Monday that Nvidia will be allowed to ship its H200 chips to China, sending shares of the chip designer up more than 1% in the after-hours session.

Per the president, 25% of the proceeds will go to the US government. That’s a step up from the 15% that Nvidia and AMD had agreed to provide the government in exchange for receiving export licenses to sell their H20 and MI308 chips to China.

Earlier in the day, Semafor reported that the Department of Commerce would soon give the go-ahead to export these powerful chips produced by Nvidia to China, which has been a core priority of the chip juggernaut, citing a source with “knowledge of the plan.” Bloomberg reported on November 21 that such a move was being considered.

The chip designer’s stock surged on the news, while Advanced Micro Devices also caught a bid.

Over the past two trading days, Marvell Technology has faced vexing questions about its relationship with its top two custom chip hyperscaler customers.

Shares are tumbling, down 9% as of 10:21 a.m. ET.

Late last week, The Information reported that Microsoft, its second-biggest custom chip buyer, was in talks to shift that business from Marvell to Broadcom.

Now, Benchmark analyst Cody Acree thinks that Marvell’s largest custom chip customer, Amazon, has done the same, writing that “we now have a high degree of conviction that the company has lost both Amazon’s Trainium3 and 4 designs to its Taiwanese competitor, Alchip.”

Acree downgraded Marvell to “hold” from “buy,” recommending that investors take profit after its post-earnings bounce.

(Harlan Sur at JPMorgan, for what it’s worth, does not believe this is the case, pointing to Marvell’s acquisition of Celestial AI as providing key technology that aligns the company with Amazon’s future chip design needs.)

During the conference call that followed earnings, Sur asked Marvell CEO Matt Murphy about its role with Amazon chips going forward.

“What I would say, which is incorporated into our numbers, is that our product transition from where we are today with our lead XPU customer to the next one is baked into all the numbers I gave you. And yes, I got the backlog, and I got the orders, and we got great visibility there,” Murphy said.

Murphy’s answer was not quite definitive, according to Acree, who thinks that Marvell’s revenue forecast is being “driven by expected continued Trainium2 volumes and a Kuiper low-earth orbit engagement and not the successful transition to Trainium3 designs that many on the sell-side have concluded.”

Structure Therapeutics soared in early trading after it reported mid-stage results for its weight-loss pill that were roughly in line with Eli Lilly’s competing product.

The San Francisco-based biotech reported that patients lost roughly 11.3% of their body weight on a lower dose of the pill, aleniglipron, in a mid-stage study. That puts it roughly in line with Lilly’s competing pill, orforglipron, and slightly below Novo Nordisk’s oral Wegovy.

Both Lilly and Novo’s pills are awaiting regulatory approval and are expected to go to market next year. While the weight-loss numbers were encouraging, Structure’s pill did report higher rates of side effects like nausea and vomiting.

Investors have been closely watching drugmakers’ once-daily pills, which could replace the weekly injections currently on the market. While pills tend to be less effective than shots, they are less expensive to manufacture than prefilled injection pens and are more inviting to squeamish patients.
