With Palantir’s stock plummeting more than 11% this week despite a better-than-expected earnings report, CEO Alex Karp took aim at investors betting against the software company.
Karp, who co-founded Palantir in 2003, went after short sellers in two separate interviews on CNBC this week. After “Big Short” investor Michael Burry revealed bets against Palantir and Nvidia, Karp on Tuesday accused short sellers of “market manipulation.”
He repeated that message on Friday in an interview with CNBC’s Sara Eisen, again knocking Burry’s wager against the stock.
“To get out of his position, he had to screw the whole economy by besmirching the best financials ever … that are helping the average person as investors [and] on the battlefield,” Karp said.
Even with Palantir’s slide this week, the stock is up 135% in 2025 and has multiplied 25-fold in the past three years, an extended rally that’s lifted the company’s market cap to over $420 billion. While revenue and profit are growing rapidly, the multiples have shot up much faster, and the stock now trades for about 220 times forward earnings, a ratio that rivals Tesla’s.
Nvidia and Meta, by contrast, have forward price-to-earnings ratios of about 33 and 22, respectively.
In August, Citron Research’s Andrew Left, a noted short seller, called Palantir “detached from fundamentals and analysis” and said shares should be priced at $40. It closed on Friday at $177.93 after late-day gains pushed the stock into the green.
Palantir, which builds analytics tools for large companies and government agencies, reported earnings and revenue on Monday that topped analysts’ estimates and issued a forecast that was also ahead of Wall Street projections.
But the stock fell about 8% after the report and then slid almost 7% on Thursday. Karp told Eisen that the recent boom in Palantir’s share price isn’t just for Wall Street.
“We’re delivering venture results for retail investors,” he said.
While Palantir has in the past faced a fairly heft dose of short interest, there are currently relatively few investors placing big bets against it. The short interest ratio, or the percentage of outstanding shares being sold short, peaked at over 9% in September and is now at a little over 2%, which is about as low as its been since the company went public in 2020.
Still, calling out the doubters is a common occurrence for Karp, who has previously said on CNBC that people should “exit” if they “don’t like the price.”
In May, after the stock plummeted following earnings, Karp said ,”You don’t have to buy our shares.”
“We’re happy,” he said. “We’re going to partner with the world’s best people and we’re going to dominate. You can be along for the ride or you don’t have to be.”
The company has also faced backlash over its work with government agencies like U.S. Immigration and Customs Enforcement, and Karp has admitted that his strong pro-Israel stance led some people to leave the company.
The boisterous CEO has been particularly vocal this week. On Monday’s earnings call, he questioned how happy the people are who didn’t invest in the company, and told them to “get some popcorn.”
And on CNBC he aimed much of his ire at Burry after the investor revealed his short positions in Palantir and Nvidia.
“The two companies he’s shorting are the ones making all the money, which is super weird,” Karp told CNBC’s “Squawk Box” on Tuesday. “The idea that chips and ontology is what you want to short is bats— crazy.”
