Nvidia shares tumbled in early Monday trading, extending the stock’s one-month decline to around 23%, amid a major pullback in global tech stocks and reports of a delay in the delivery of its newly-designed AI chips known as Blackwell.  

Nvidia  (NVDA) , which unveiled the Blackwell line of processors earlier this year, has said the flagship chips perform AI tasks at more than twice the speed of Nvidia’s current Hopper chips, while using less energy and providing more bespoke flexibility.

The tech giant said it would ramp production of the new processors over the second half of this year, while continuing to sell its H100 “Hopper” series to hyperscaler clients such as Microsoft  (MSFT) , Meta Platforms  (META)  and Google parent Alphabet  (GOOGL) .

Hyperscalers are in fact are poised to spend around half a trillion dollars over the next two years building out their massive computing infrastructure, according to estimates from Barclays, as they leverage their massive datasets to enhance sales of everything from drive-through dining to the most complicated pharmaceutical testing.

Nvidia CEO Jensen Huang has said Blackwell could be the “most successful product” in the history of the tech industry.

Tech-focused news outlet The Information, however, has reported the Nvidia had informed Microsoft, as well as an unnamed could service provider client, that a design flaw had been found in the Blackwell architecture that could delay its production ramp and delivery dates by around three months.

Blackwell revenues key

Analysts had expected Blackwell to generate revenues for Nvidia starting in the third quarter of this year, and find their way into global customer data centers by the final three months of the year. 

AI demand, as well as Nvidia’s commanding market share, is predicted to drive the group’s data center revenues to as high as $150 billion next year, powered largely by this year’s Blackwell launch.

“With Blackwell said to be in full production in the second quarter, Nvidia is working to bring up its enterprise system and cloud partners for global availability later this year, with the ramp expected in Q3 and the company anticipating data centers should be operational by Q4,” Benchmark analyst Cody Acree said in a note that followed Nvidia’s second quarter earnings. 

“Demand for H200 and Blackwell is well ahead of supply, and the company expects demand may exceed supply well into next year,” he added.

Goldman Sachs analyst Toshiya Hari, who reiterated his ‘conviction buy’ rating and $135 price price target on Nvidia stock following the weekend report, said he remained confident that Blackwell revenues would remain a major part of the group’s near-term growth story. 

“While (the report), if true, could drive some volatility in Nvidia’s near-term fundamentals (i.e., muted growth in the October and/or January quarters followed by a steeper than previously expected ramp), we expect there to be little to no impact on CY2025 earnings and, most importantly, the company’s long-term competitive position,” he said.

Nvidia, which reports third quarter earnings later this month, told investors in May that current-quarter revenues would rise to around $28 billion, a strongr-than-expected tally that assuaged investors concerns over a so-called air pocket created by the Blackwell launch.

Some investors had worried that customers would cancel orders for the older H100 chips and wait for the newer system processors to ship later in the year.
