Palantir Technologies CEO Alex Karp unloaded more than 400,000 shares in the data-analytics company last week, according to a filing with the Securities and Exchange Commission.

A Form 4 filed with the agency on Friday showed that Karp sold 409,072 shares of common stock, at prices ranging from $142.46 to $157.56 a share, on Wednesday and Thursday. The sales were executed through automatic transactions to cover tax-withholding obligations following the vesting of restricted stock.

Following the transactions, Karp owned about 6.43 million shares of Palantir, which were valued at more than $1 billion as of Monday afternoon.

For most of the year, Palantir stock seemed untouchable, continuing to rise regardless of concerns about its lofty valuation and high volatility. Shares have gained 109% this year.

However, their rise has been challenged as of late. Shares of the artificial-intelligence heavyweight fell for the six consecutive trading sessions through Wednesday, their longest losing streak since April 2024. The decline came after strong second-quarter results caused the stock to surge earlier this month.

Other big names in tech, notably AI plays such as Nvidia , have come under pressure as investors question the effects of the technology and how long the current red-hot enthusiasm for it will last. OpenAI CEO Sam Altman’s remarks that investors were “overexcited” about AI, and an MIT report casting doubt on the revenue-generating potential of generative AI, appeared to be compounding the downturn.

Given all that, scrutiny is mounting ahead of Nvidia earnings later this week. The chip maker is seen as a bellwether for the broader AI and semiconductor industries. Commentary from CEO Jensen Huang is expected to shed light on the state of AI demand.

How those results will affect Palantir stock isn’t clear. The shares were down 0.9% at $157.39 on Monday. The , which counts Palantir among its major holdings, was up 0.4%.
