Palantir (PLTR) Stock: Weekend Update After Friday Slide, Fresh Wall Street Debate, and What to Watch Before Monday’s Open

NEW YORK, Dec. 27, 2025, 6:15 p.m. ET — Market closed

Palantir Technologies Inc. (PLTR) heads into the weekend with investors weighing a familiar late-cycle question: how much is already priced into one of 2025’s biggest AI software winners?

Shares of Palantir (NASDAQ: PLTR) finished the most recent session on Friday, Dec. 26 at $188.71, down about 2.8% on the day, and were last indicated near $188.20 in after-hours quotes. ^[1] With U.S. equity markets closed for the weekend, the next key test for PLTR will be whether buyers step back in when trading resumes Monday—especially with the stock still near the upper end of its 52-week range ($63.40–$207.52) after a dramatic 2025 run. ^[2]

What happened to Palantir stock in the latest session

Friday’s decline came in thin, post-holiday trading, with broader indexes drifting and many traders focused on year-end positioning rather than new fundamental catalysts. Investor’s Business Daily noted that Palantir fell about 2.8% and dropped below a closely watched 190.39 “buy point” that technical traders have been tracking. ^[3]

MarketBeat similarly highlighted light volume versus typical levels—often a hallmark of late-December sessions—while underscoring how elevated Palantir’s valuation remains even after a down day. ^[4]

The last 24–48 hours of PLTR headlines investors are reading

Several widely shared analyses over the past two days converged on the same tension: strong operating momentum vs. unforgiving valuation.

Valuation “wall” thesis: In a Dec. 27 analysis, Investing.com contributor Itai Smidt argued markets are increasingly treating Palantir like a “core AI platform,” leaving little room for execution missteps. The piece cited Palantir’s rapid growth and expanding margins, but emphasized that high multiples can amplify volatility if growth expectations cool. ^[5]
Profit-taking case: In a Dec. 26 commentary, Motley Fool analyst Daniel Sparks said Palantir’s business momentum is real, but warned the stock’s valuation “assumes near-flawless execution,” suggesting some investors may consider trimming rather than exiting outright. ^[6]
Bear-case target cited: Another Motley Fool piece (Dec. 26) pointed to RBC Capital carrying a $50 price target—a sharply bearish view that reflects concerns about whether growth can stay strong enough to justify current pricing. ^[7]
Institutional ownership/filing chatter: MarketBeat reported Dec. 27 that Carnegie Investment Counsel trimmed its Palantir position in the third quarter, adding to the narrative that institutions may be more selective at current valuation levels. ^[8]

Taken together, the last 48 hours of coverage is less about a single breaking headline—and more about how investors should frame PLTR into year-end: momentum stock, mega-cap AI proxy, or valuation trap depending on time horizon and risk tolerance. ^[9]

Fundamentals that bulls cite—and why bears keep pushing back

The bull case: AIP-driven growth and expanding profitability

Recent analyses continue to highlight Palantir’s acceleration tied to its Artificial Intelligence Platform (AIP) and rising commercial demand. Investing.com’s Itai Smidt pointed to Q3 revenue of about $1.18 billion and rapid growth in U.S. commercial revenue, alongside margin expansion that has helped fuel the stock’s multi-year surge. ^[10]

Motley Fool’s Daniel Sparks echoed the operational momentum and included a quote attributed to CEO Alex Karp emphasizing AIP’s impact: “These results make undeniable the transformational impact of using AIP…” ^[11]

The bear case: Expectations are already extreme

Even many neutral-to-positive takes acknowledge the market is demanding a lot from Palantir. Investing.com’s analysis flagged a very high trailing P/E and warned that any stumble—or even a “good but not spectacular” growth outlook—could trigger multiple compression. ^[12]

Google Finance’s snapshot also reflects how stretched valuation looks on traditional metrics, listing a P/E ratio north of 400 alongside a market cap near $450 billion. ^[13]

And in the more overtly bearish camp, the RBC Capital target cited by Motley Fool stands out because it implies a dramatically different view of what Palantir’s future cash flows should be worth. ^[14]

Analyst targets and forecasts: a wide range, with “Hold” still common

If there’s one word that captures the Street’s stance entering 2026, it’s mixed.

MarketBeat’s roundup describes a consensus view that leans “Hold”, with an average price target around $172.28—below recent trading levels—despite several banks previously lifting targets toward the $200–$225 range after earnings. ^[15]

Examples MarketBeat cited from prior research notes include:

Robert W. Baird: target raised to $200 (neutral)
Deutsche Bank: target raised to $200 (hold)
Piper Sandler: target raised to $225 (overweight)
^[16]

Meanwhile, more valuation-focused commentary continues to argue that even if Palantir executes, the stock may deliver choppier returns simply because expectations are so elevated. ^[17]

Next earnings date: watchlists say “early February,” but timing can vary

Several earnings calendars estimate Palantir’s next report for early February 2026, while noting the date may be unconfirmed until the company formally announces it. ^[18]

Insider selling and positioning: another weekend talking point

One reason valuation debates stay intense around PLTR: investors also track insider selling and institutional flows closely.

MarketBeat’s Dec. 27 report highlighted recent insider sales totals and stated insiders own roughly 9.23% of the stock, while also noting heightened sensitivity to valuation at current levels. ^[19]

(Insider sales can occur for many reasons—including pre-planned trading programs—so investors typically look for patterns over time rather than treating any single transaction as a standalone signal.)

What investors should know before the next session

With markets closed, PLTR investors are essentially prepping for a Monday, Dec. 29 reopen with two key dynamics in play: holiday liquidity and year-end positioning.

1) Expect holiday-thin trading to continue

Late-December liquidity can exaggerate moves in both directions. That’s especially relevant for a high-beta, sentiment-driven name like Palantir, where positioning and headlines can matter as much as fundamentals on any given day. ^[20]

2) Key technical levels many traders are watching

Coverage over the past two days repeatedly referenced:

The 190.39 level highlighted by Investor’s Business Daily (a key “buy point” technicians cite) ^[21]
The psychological $200 area (also where multiple banks have clustered targets) ^[22]
The prior peak zone near the $207.52 52-week high ^[23]

3) Calendar risk into year-end and early January

Investopedia noted that the market schedule into the turn of the year includes a full trading day on Dec. 31, while markets are closed on Jan. 1, 2026 for New Year’s Day (and bond trading has its own holiday timing). ^[24]
Nasdaq’s holiday schedule also reflects the standard year’s market closures and early closes, which can shape liquidity and flows around the holidays. ^[25]

4) The headline risk remains two-sided

Going into Monday, the risk/reward for Palantir tends to hinge on:

Any incremental contract / partnership headlines (which have historically been catalysts for PLTR sentiment) ^[26]
Any renewed commentary about valuation and growth durability—the dominant theme in the last 48 hours of coverage ^[27]

Bottom line for Palantir stock heading into Monday

As of this weekend close, Palantir stock is not reacting to a single breaking event. Instead, the latest move looks like a year-end consolidation inside a longer-term uptrend—while investors digest a wave of commentary that essentially says: Palantir’s growth story is strong, but the market is already pricing it like a “must-win” platform.

When trading resumes Monday, the immediate questions are whether PLTR can reclaim key technical levels cited by traders—and whether broader AI sentiment stays supportive into the final days of 2025 and the first sessions of 2026. ^[28]
