CBRS Dips In Premarket: CEO Reportedly Says Working With All AI Component Makers Except Nvidia

• Cerebras shares have declined gradually after sharp gains on the opening day on Nasdaq on May 14.
• Cerebras positions itself as a simpler, high-speed alternative to Nvidia by using a single massive chip rather than many smaller ones.
• Stocktwits sentiment for CBRS turned ‘bearish.’

Cerebras Systems shares fell nearly 1% in premarket trading Thursday, extending their pullback since the company’s market debut last month, while retail investor interest in the stock also showed signs of easing.

On Wednesday, CEO Andrew Feldman said Cerebras is engaged with multiple players that supply components for data centers, except Nvidia. Speaking at the Bloomberg Tech conference in San Francisco, Feldman indicated plans to cooperate with a wide variety of suppliers, opening the way for further partnerships that mirror its agreement with Amazon.

Amazon is using Cerebras’ chips alongside its own in AWS data centers as part of a partnership between the two companies. The maker of the so-called wafer-scale processors also has a similar deal with OpenAI.

CBRS Stock Move

Cerebras, which develops giant AI chips designed to train and run AI models much faster than traditional GPUs, listed its stock on the Nasdaq Global Select Market on May 14 and gained 68% over its IPO price on the opening day. The listing was the biggest in 2026 so far.

However, CBRS stock has faced a downward trend since and is down 31% from the opening day closing price, contrasting gains in the broader semiconductor market sector.

Cathie Wood Accumulates CBRS

Notably, Cathie Wood’s ARK Investment has been loading up on CBRS stock. The investor picked up a $32.8 million lot on Cerebras' listing day and a $14.85 million lot earlier this week.

Still, retail investors appear to be turning out for now. On Stocktwits, the retail sentiment has remained ‘bearish’ since the start of last week.

Retail View On CBRS

$CBRS So basically this is another one of those "it's a zero or it's a hero" stocks,” remarked a trader. “The technology is either superior to GPU's, or it isn't. And if it isn't, it's a goner. And if it is, well then $NVDIA, $AMD and maybe $INTC are goners”

Some still remained optimistic. “$CBRS accumulated heavily in the 150s. If you actually do some due diligence on this wafer style chip and how much faster it is and more energy efficient with memory storage built in than $NVDA GPU’s you would be buying to,” said a trader.

As of the market close on Wednesday, Cerebras’ market capitalization was $47.2 billion.
