Likens Nvidia ( NVDA ) to Cisco during the dot-com era

Nov 24 (Reuters) -

"The Big Short" investor Michael Burry, a vocal skeptic of

the current AI boom, took aim at Nvidia ( NVDA ) as he launched a paid

Substack newsletter focused on financial markets, days after

shutting down his hedge fund.

Burry, who shot to fame for betting against the U.S. housing

market ahead of the 2008 financial crisis, is widely watched for

his comments on markets and the economy. His bets have long been

dissected by traders for clues on looming bubbles and signs of

market froth.

"I am not retired," Burry wrote on Substack, adding that the

blog titled Cassandra Unchained had his "full attention."

The newsletter currently has more than 21,000 subscribers

and costs $39 per month. He hinted at a publication schedule of

generally one or more pieces most weeks.

In his post titled "Foundations: My 1999 (and part of

2000)," Burry discusses his early interests and how he started

trading.

He compares the recent AI boom to the 1990s dot-com era in

another post titled "The Cardinal Sign of a Bubble: Supply-Side

Gluttony." The investor said he would continue writing about his

findings in upcoming posts.

"The five public horseman of today's AI boom -

Microsoft, Google, Meta, Amazon and Oracle - are joined by

several adolescent startups in promising nearly $3 trillion in

spending on AI infrastructure over the next 3 years. Investors

absolutely love it," he wrote.

"And once again there is a Cisco at the center of it

all, with the picks and shovels for all and the expansive vision

to go with it. Its name is Nvidia ( NVDA )."

Burry recently stepped up criticism of technology

heavyweights, including Nvidia ( NVDA ) and Palantir

Technologies ( PLTR ), questioned the cloud infrastructure boom

and accused major providers of using aggressive accounting to

inflate profits from their massive hardware investments.

Earlier this month, Burry closed Scion Asset Management and

returned capital to investors.

He said managing money professionally came with

regulatory and compliance constraints that "effectively muzzled"

his ability to communicate, leading to misunderstandings around

his SEC filings that sparked market turmoil and heated debates

that he never intended.

Burry did not immediately respond to a Reuters request for

comment.

Burry's short position against subprime mortgage securities

during the housing market crash was chronicled in Michael

Lewis's book "The Big Short" and its film adaptation.
