‘Big Short’ investor Michael Burry is back with a bubble warning after 2 years of silence

• Michael Burry of “The Big Short” fame just posted on X for the first time since April 2023.

• The investor said that even if there’s a bubble, sometimes the “only winning move is not to play.”

• Burry also updated his profile, doubling down on his reputation as a pessimistic forecaster.

Michael Burry is back with a bang.

The investor of “The Big Short” fame posted on X for the first time since April 2023 on Thursday. He shared a still from the movie of actor Christian Bale, who portrayed Burry, staring at a computer screen in disbelief.

“Sometimes, we see bubbles,” he wrote. “Sometimes, there is something to do about it. Sometimes, the only winning move is not to play.”

That’s a reference to the 1983 movie “WarGames,” in which an AI runs thousands of simulations of nuclear exchanges between the US and Soviet Union and discovers they all end in mutual destruction. “A strange game,” the supercomputer says. “The only winning move is not to play.”

Burry’s pinned post suggests he sees unsustainable levels of speculation in markets that he expects to end in devastation, and he’s decided that steering clear of the AI boom, instead of betting on or against it, is the only winning strategy.

Immense buzz over AI has boosted Big Tech stocks such as Nvidia; its shares have surged over 1,200% since the start of 2023, propelling it to an unprecedented $5 trillion market value this week, and helping to catapult the S&P 500 and Nasdaq 100 indexes to record highs in recent days.

Burry updated his profile name to “Cassandra Unchained,” referring to the priestess in Greek mythology who was cursed to make accurate prophecies but never to be believed. He also changed his bio to read: “One ready to share what I know.”

Echoing his return to the social media platform in November 2021, Burry once again changed his header image to “Satire of Tulip Mania,” a painting by Jan Brueghel the Younger that ridicules the Dutch tulip bubble in the 1600s.

Burry is best known for predicting and profiting from the collapse of the housing bubble in the mid-2000s. His contrarian wager was immortalized in the book and film “The Big Short.”
