Michael Burry is escalating his campaign against Palantir Technologies. The famed 'Big Short' investor is alleging covert corporate tactics in a series of X posts on Sunday.
“Let’s try this again. If you have real evidence that Palantir has continued this practice of covert smearing campaigns against the enemies (CEO Alex) Karp and $PLTR cannot quite reach with Fentanyl-laced urine drones, please contact me,” Burry wrote.
He shared a 2024 news report saying that Palantir had hired a marketing agency for an influencer campaign to counter criticism of the patient data platform it was building for the UK’s National Health Service (NHS), in a breach of contractual terms.
In a separate X post, Burry shared a 2017 BuzzFeed report, which said that Palantir obstructed its client, the New York Police Department, from developing tools to replace Palantir’s software and proceed with a tie-up with IBM.
Palantir shares were down 1.5% in early premarket trading on Tuesday. Monday was a market holiday.
Burry’s weekend comments signal an escalation in his criticism of the AI data analytics company that has captivated investors over the past two years.
Burry first disclosed a short position in Palantir last November, a development that has pressured the company’s shares since. Earlier this month, Burry teased a technical analysis showing a head-and-shoulders forming pattern in the PLTR chart and forecasted an over 40% drop in price from the levels at the time.
Even as Palantir reported blowout results for the last quarter, shares have continued to be under pressure. PLTR stock declined 26% year to date and currently trades around an eight-month low.

On Stocktwits, retail sentiment for the stock dropped gradually over the past week and was ‘bearish’ as of early Tuesday.
In a bullish signal, Norges Bank Investment Management disclosed a $5.15 billion new stake in Palantir last week.
