A tiny semiconductor company is more than doubling after becoming an Nvidia supplier

The seal of approval is sending shares of Navitas Semiconductor soaring.

A tiny semiconductor company with fewer than 300 employees is mooning after receiving the biggest blessing any firm in the industry could dream of: earning a place in Nvidia’s supply chain.

“We are proud to be selected by NVIDIA to collaborate on their 800 HVDC architecture initiative,” Navitas Semiconductor CEO and cofounder Gene Sheridan said in a press release on Wednesday evening. “We appreciate that NVIDIA recognizes our technology and commitment to driving the next generation of data center power delivery.”

Shares are up about 170% as of 8:00 a.m. ET.

A post on Nvidia’s technical blog on Tuesday called Navitas a key silicon provider in its new data center infrastructure push.

“Today’s racks in AI factories rely on 54 V DC power distribution, where bulky copper busbars shuttle electricity from rack-mounted power shelves to compute trays. As racks exceed 200 kilowatts, this approach begins to hit physical limits,” like space constraints, massive amounts of copper, and inefficient power conversions, per the post.

Nvidia’s looking to leverage Navitas’ integrated circuits and silicon carbide semiconductors to help improve on these fronts.

Two musings on this:

1) How in the world isn’t some algorithm scraping all of Nvidia’s corporate sites for mentions of companies and taking positions in stocks that had no previously disclosed relationship with the semi designer giant?!?! That developer blog, again, was published on Tuesday. Shares of Navitas were down on Tuesday and down again on Wednesday before Thursday’s surge. Navitas had never been mentioned on any of Nvidia’s technical or corporate blogs, or anywhere else on its site for that matter, before the Tuesday post.

2) More of an aside, on how fickle success can be: take a peek at Wolfspeed. The company cratered this week after filing for bankruptcy, and its fall from grace was certainly exacerbated by Tesla’s decision a couple years ago to use less silicon carbide semiconductors in manufacturing electric vehicles. Now, silicon carbide chips are playing a key role in another company more than doubling.

The Torrance, California-based Navitas went public in 2021 via the SPAC boom.

Traders are pricing in a big swing in AI chip market share to Broadcom from Nvidia

The story within the AI trade lately has been: Google’s a winner, and OpenAI is a... well, to be kind, non-winner.

Companies closely tied to the former, like Broadcom, which codesigns the TPUs that Gemini 3 was trained on, have benefited from their relationship with the hyperscaling search giant. Conversely, Nvidia, which sells to both Google and OpenAI but is besieged with worries about how custom chips might impact its AI market share (and profitability), has been selling off.

“NVDA stock is now trading at its widest ever ~40% discount to AVGO’s current 42x forward PE versus historical -10%/+7% discount/premium over the past 1/2 yrs, respectively,” Bank of America analyst Vivek Arya wrote. “In other words, consensus has already implicitly shifted at least 10+ points of (2H26E/27E) AI market share towards AVGO, conceptually.”

The abrupt shift in valuation amid this divergent price action is reversing course on Monday: Nvidia’s up about 1.5% as of 10:55 a.m. ET, while Broadcom is off 2.6%.

Air taxi companies are in the red as Goldman initiates coverage on Archer, Joby, and Beta

Goldman Sachs initiated coverage of the major US air taxi companies on Monday, including Joby Aviation, Archer Aviation, and Beta Technologies. All three are trading down as the bank’s first notes hit investor inboxes.

Though Joby “appears to be in pole position” on certification, analyst Anthony Valentini gave the stock a “sell” rating and a $10 price target — 30% below the value of Joby’s stock at Friday’s close. Valentini wrote that it’s unclear where competitors stand in the process.

Goldman gave Archer a “neutral” rating and an $11 price target, highlighting the company’s ability to cut spending. Beta Technologies, which went public last month, received a “buy” rating and a $47 price target.

Crypto-adjacent stocks drop to start the week

Crypto-adjacent shares slid in early trading along with unprofitable tech company shares, as animal spirits ebbed to start the US trading week.

Goldman Sachs’ basket of bitcoin-sensitive stocks — heavily weighted toward Coinbase and treasury companies like MARA Holdings and Strategy — was down more than 3% early, reflecting another tumble in bitcoin overnight, though bitcoin prices stabilized a bit in early US trading. Robinhood Markets — shares of which have at times taken cues from the price of crypto, which is traded on the brokerage app — was also down.

(Robinhood Markets Inc. is the parent company of Sherwood Media, an independently operated media company.)

It would take a talented druid and a flock’s worth of bird entrails to the divine precisely what’s driving the downdraft. But S&P’s recent assessment of the vulnerability of Tether’s stablecoin, USDT — the world’s largest of these supposedly safer forms of crypto — to the bitcoin sell-off might be playing a role.
