- Palantir shares fell $4.51, or 2.4%, to $184.20 in after-hours trading.
- The stock traded between $183.67 and $188.01 in Monday’s regular session.
- Investors are watching thin holiday liquidity, key U.S. data, and the next earnings timetable.
Palantir Technologies Inc (PLTR) shares fell $4.51, or 2.4%, to $184.20 in after-hours trading on Monday. The stock traded between $183.67 and $188.01 in the regular session, with about 26.4 million shares changing hands.
The slide matters because Palantir has been one of 2025’s standout gainers, and year-end trading often magnifies profit-taking in high-flyers. The stock is up about 145% so far this year, according to Yahoo Finance. Yahoo Finance
The broader tape turned softer into the final week of the year, with the S&P 500 down 0.34%, the Nasdaq off 0.50% and the Dow down 0.50% as big tech stocks pulled back, Reuters reported. “This is (not) the beginning of the end of the tech dominance, it’ll turn out to be a buying opportunity,” said Hank Smith, director and head of investment strategy at Haverford Trust.

After-hours trading is the session after the 4 p.m. ET market close, when liquidity is typically thinner and prices can swing more sharply than during the regular session.
Palantir has traded this year as a high-beta proxy for investor appetite around AI-linked software, often moving with the broader tech complex rather than on single-stock headlines.
Still, Palantir was not completely absent from the day’s news cycle. Investopedia reported CEO Alex Karp is promoting a paid “Meritocracy Fellowship” aimed at high school graduates, a program the outlet said pays about $5,400 a month and runs a four-month curriculum. Investopedia
The company sells data integration and analytics software to governments and businesses, and has marketed its Artificial Intelligence Platform, or AIP, as a way for customers to deploy advanced AI tools on top of their own data.
That positioning has helped put the stock in the same bucket as other AI-linked names, where sentiment can shift quickly on macro headlines, rates expectations and year-end positioning.
On the chart, Monday’s move left shares hovering just above the day’s low of $183.67, a level short-term traders often treat as near-term support. The prior close around $188.71 now sits as the first nearby resistance.
Looking ahead, Palantir has not announced the date for its next quarterly results, and trading calendars vary. Nasdaq currently lists an estimated earnings date of Feb. 2, 2026, on its PLTR earnings page. Nasdaq Nasdaq
Any update on 2026 demand for Palantir’s AI products, along with margins and cash generation, is likely to carry extra weight after the stock’s sharp 2025 run.
For now, PLTR is moving with the year-end tone in tech, as investors weigh whether the latest dip becomes a pause — or a deeper pullback — into the turn of the calendar.
