Palantir (NASDAQ: PLTR) stock has fallen nearly 2.5% to $148 in overnight trading ahead of the June 3 session, extending an already hefty 5.3% decline from the previous day, fueled by insider selling activity.
The insider moves in question came from director Lauren Friedman Stat, who has sold more than $505,000 worth of Palantir shares. According to her filings, the sale involved 3,265 shares and was executed on May 29 and June 1, 2026, at prices ranging from $150 to $160 per share. Friedman Stat still owns 55,022 Class A shares directly.
Made under a prearranged Rule 10b5-1 trading plan, Friedman’s transaction followed much larger sales. For example, Chief Technology Officer (CTO) and Executive Vice President (EVP) Shyam Sankar sold 165,514 shares worth roughly $22.5 million in February, while President and Co-founder Stephen Cohen offloaded 3.75 million shares in March at a value of $310 million.
As a result, Palantir currently carries a ‘Negative Insider Confidence Signal,’ according to TipRanks data.

‘Palantir is a sand castle,’ Michael Burry says ahead of shareholder meeting
Adding to the cautious sentiment, famed investor Michael Burry said on Tuesday that he remains bearish on the Palantir stock price. In a blog post, he mentioned the stock’s struggle with a head-and-shoulders pattern, which, if shares break below the so-called neckline support level, could confirm a larger downtrend.
In essence, he argued that investor enthusiasm surrounding the company may be fading and that the stock has reached a critical technical juncture, where a deeper correction could follow. Or, as Burry put it elsewhere in the post, ‘Palantir is a sand castle.’
“Palantir’s chart shows the price is at a crossroads after a head-and-shoulders-type top. This reflects the waxing and waning of extremely bullish psychology,” the ‘Big Short’ wrote.
Whether Burry’s now-signature pessimism is going to be justified or not, the fact remains that Palantir is struggling to maintain momentum in 2026, following some of the strongest performances in the sector last year.
The stock is down roughly 14% year-to-date, and investors are turning their attention to the next annual shareholder meeting scheduled for later today, waiting for potential catalysts and updates on the company’s outlook.
