Palantir Stock (PLTR): What to Know Before the U.S. Market Opens on Monday, Dec. 15, 2025

Palantir Technologies (NASDAQ: PLTR) heads into the Monday, Dec. 15 session after a volatile stretch that has still left the stock massively higher over the past year—and squarely in the spotlight of two powerful themes: defense modernization and the AI infrastructure buildout.

As of the Friday, Dec. 12 close, PLTR finished at $183.57 (down 2.12% on the day), after trading between roughly $177.67 and $186.52, with volume around 42.43 million shares. ^[1]

Below is what investors and traders typically want on their radar before the bell: the latest headlines, the most important fundamentals from Palantir’s most recent quarter, where Wall Street stands on valuation, and the key catalysts that could move PLTR next.

Palantir stock: the key points before the bell

Latest price action: PLTR closed $183.57 on Dec. 12; some feeds showed after-hours around $182 late Friday. ^[2]
Big defense catalyst: The U.S. Navy announced a ShipOS initiative “authorizing up to $448 million” tied to deploying Palantir software across the Maritime Industrial Base—an eye-catching headline for Palantir’s government business narrative. ^[3]
AI infrastructure catalyst: Palantir, Nvidia, and CenterPoint Energy said they’re developing “Chain Reaction,” a platform aimed at accelerating AI data center development (permitting, supply chain, construction coordination). ^[4]
Fundamentals remain hot: Palantir reported Q3 revenue of $1.181B (+63% YoY), with U.S. commercial revenue +121% YoY to $397M and U.S. government revenue +52% YoY to $486M—and it raised full‑year guidance. ^[5]
Headline risk is real: Palantir expanded litigation involving a rival AI startup and a former employee group, alleging wrongdoing; legal disputes can add near-term volatility. ^[6]
AI “trade” volatility: A late-week shakeout in parts of the AI market revived “bubble” chatter—an important backdrop for a high‑beta, AI-linked stock like PLTR. ^[7]
Wall Street is split: Consensus views cluster around neutral/hold, but price targets span a wide range—from very bearish to very bullish. ^[8]

Where PLTR left off: price, momentum, and volatility

Palantir’s run in 2025 has been powerful but not smooth. The stock is still up more than 140% over the past year, and its 52-week range has been exceptionally wide—roughly $63.40 to $207.52, reflecting both momentum and sharp pullbacks. ^[9]

Two numbers matter if you’re trading around the open:

All-time high reference point: PLTR hit an all-time high of $207.52 on Nov. 3, 2025, which remains a psychological level many traders watch. At Friday’s close near $183.57, the stock sits roughly ~12% below that peak. ^[10]
Volatility profile: TradingView data characterizes PLTR as high-beta (beta shown around 2.21) and volatile—exactly the kind of name that can gap on headlines. ^[11]

With that setup, Monday’s early direction often comes down to whether weekend sentiment leans “risk-on” (chasing AI winners) or “risk-off” (punishing rich valuations), and whether new contract/legal headlines emerge.

The biggest near-term headline: the Navy’s $448 million ShipOS initiative

The most concrete recent catalyst is the Navy’s ShipOS announcement.

According to a U.S. Navy press release dated Dec. 9, 2025, the Secretary of the Navy announced a $448 million strategic investment in the “Shipbuilding Operating System (Ship OS)” aimed at accelerating AI and autonomy adoption across the industrial base, and the release explicitly says Ship OS will leverage Palantir’s software. ^[12]

Two details stand out for investors:

Measured operational impact (not just “AI buzzwords”).
The Navy said pilot deployments produced dramatic cycle-time improvements—for example:
- At General Dynamics Electric Boat, “submarine schedule planning was reduced from 160 manual hours to under 10 minutes.”
- At Portsmouth Naval Shipyard, “material review times” were cut “from weeks to under one hour.” ^[13]
A scaled deployment footprint.
A Business Wire company announcement (timestamped Dec. 10, 2025) described ShipOS as authorizing up to $448 million and said the software would initially be deployed across two major shipbuilders, three public shipyards, and 100 suppliers across the Maritime Industrial Base. ^[14]

Why this matters for PLTR stock before Monday’s open:

It reinforces Palantir’s positioning as a “mission-critical” platform vendor in defense modernization (a premium narrative in a market that rewards visible, high-stakes use cases).
It also puts a spotlight on implementation execution—because investors will want to see whether “authorized up to” becomes sustained revenue and renewals over time.

AI infrastructure story: Palantir + Nvidia + CenterPoint and the “Chain Reaction” platform

A separate catalyst sits squarely in the AI infrastructure boom: Reuters reported on Dec. 4, 2025 that Palantir, Nvidia, and CenterPoint Energy said they are developing a software platform called Chain Reaction to accelerate construction of AI data centers. ^[15]

Reuters’ description frames the product as an AI-assisted coordination layer that tackles data center build friction points like:

Permitting
Supply chain bottlenecks
Construction scheduling and interdependencies ^[16]

For PLTR investors, this is notable because it expands Palantir’s addressable narrative beyond “government + enterprise AI” into the physical buildout behind AI—power, grid upgrades, and the complex multi-party supply chain required to deploy compute at scale.

The fundamental engine: what Palantir just delivered (and guided)

Even with the headline catalysts, the stock’s medium-term direction still tends to track one thing: growth + margins + forward guidance.

Palantir’s official Q3 2025 earnings release (filed on the SEC site) shows:

Revenue: $1.181 billion in Q3 2025 (+63% YoY) ^[17]
U.S. revenue: $883 million (+77% YoY) ^[18]
U.S. commercial revenue: $397 million (+121% YoY) ^[19]
U.S. government revenue: $486 million (+52% YoY) ^[20]
Profitability (Q3): GAAP operating income $393M (33% margin), adjusted operating income $601M (51% margin) ^[21]
Cash / liquidity: cash, cash equivalents, and short-term U.S. Treasuries of $6.4B ^[22]

Guidance: why it moved the conversation

Palantir also guided higher:

Q4 2025 revenue: $1.327B to $1.331B ^[23]
Full-year 2025 revenue: $4.396B to $4.400B ^[24]
Full-year U.S. commercial revenue: guided to in excess of $1.433B (and described as at least 104% growth) ^[25]
Full-year adjusted free cash flow: $1.9B to $2.1B ^[26]

And in commentary from the Q3 earnings call transcript, management described record bookings dynamics and segment mix—reporting $2.8B in TCV bookings (up 151% YoY), commercial revenue of $548M in the quarter, and government revenue of $633M. ^[27]

For Monday’s setup, the “bull case” remains straightforward: the U.S. commercial growth rate stays elevated, while government programs (like ShipOS) add durable long-cycle demand.

Analyst forecasts and price targets: why investors keep arguing about PLTR

Palantir is one of those stocks where the spread between bullish and bearish targets tells you as much as the targets themselves.

Benzinga lists a highest analyst price target of $255 and a lowest of $20, with a “consensus price target” around $156 (based on the analyst set it tracks). ^[28]
MarketBeat shows a consensus rating of “Hold” (with a breakdown it reports as 2 sell, 17 hold, 4 buy) and an average price target near $172.28 (implying modest downside from $183.57 on its page at that time). ^[29]
Simply Wall St’s forecast page (last updated Dec. 10, 2025) projects Palantir to grow earnings ~30% per year and revenue ~27.2% per year (its compiled forecast view). ^[30]

How to read the split

This is the heart of the PLTR debate:

Bulls point to accelerating commercial adoption, expanding deal sizes, and the idea that Palantir is becoming a core “operating system” for AI-enabled decision-making in both industry and defense. (ShipOS and the Chain Reaction project strengthen that story.) ^[31]
Bears often focus on valuation and the risk that growth slows from “hyper” levels, causing the market to compress the multiple—even if the business keeps performing.

Going into Monday, the key is that expectations are already high. That amplifies the impact of incremental news—good or bad.

Headline risk: lawsuit developments involving a rival AI startup

Legal developments can be secondary to fundamentals—but they still matter for a stock with PLTR’s volatility profile.

Bloomberg reported on Dec. 11, 2025 that Palantir added Hirsh Jain, co-founder and CEO of Percepta, to an existing lawsuit, and that Palantir included in court documents a text message allegedly discussing “pillage the best devs at palantir,” tying him to what Palantir alleges is illegal conduct by former executives. ^[32]

Investors typically watch two angles here:

Operational impact: whether litigation distracts leadership or affects talent retention (especially for a company where high-end engineering talent is core).
Narrative impact: whether it highlights competitive pressure in enterprise AI software.

Political and reputational risk: scrutiny over government work

Palantir’s government exposure is a feature for many shareholders—but it can also be a reputational and political lightning rod.

The Washington Post reported in early December that Palantir software is helping ICE with what it described as “Immigration OS,” citing federal procurement filings and interviews; the article also cited figures such as a contract initially awarded at $30 million and renewed in late September, bringing total value to about $60 million, and described internal controversy and broader public debate. ^[33]

Whether or not this affects Monday’s open, it’s part of the headline risk investors should be aware of—because it can influence sentiment, employee perception, and (in some cases) procurement politics.

The market backdrop: AI trade turbulence can spill into PLTR quickly

One reason Palantir can swing hard at the open—even without company-specific news—is that it often trades as part of the broader “AI basket.”

Reuters noted on Dec. 12, 2025 that troubling updates from other major tech names bruised AI-linked stocks and revived bubble concerns, while also reporting that well-known investor Michael Burry has criticized valuations and has a short position in Palantir (per Reuters’ reporting and referenced posting). ^[34]

For Monday morning, that means PLTR can react to:

changes in risk appetite for high-multiple AI names,
big-mover reactions in adjacent AI leaders,
and any renewed “AI spending” narrative shifts.

What to watch right at Monday’s open

If you’re tracking Palantir into Dec. 15, here’s what tends to matter most in the first 30–90 minutes of trading:

Any follow-through (or fade) from the ShipOS narrative
Investors will ask whether “authorized up to $448M” signals a broader wave of similar defense industrial base modernization programs. ^[35]
AI infrastructure sentiment
“Chain Reaction” keeps Palantir in the AI data center buildout conversation alongside Nvidia and a major utility—potentially supportive if markets rotate back toward AI exposure. ^[36]
Volatility + technical levels
With PLTR’s high beta and recent wide ranges, traders often key off the prior close ($183.57), the prior day low ($177.67), and the broader context of the $207.52 all-time high. ^[37]
Any new lawsuit or policy headlines
These can trigger abrupt gaps—especially pre-market—because they’re hard to model and easy to trade emotionally. ^[38]

Bottom line

Palantir enters Monday’s session as a high-momentum, high-expectations AI and defense software name: the company just delivered strong Q3 growth and raised guidance, then followed it with a marquee Navy modernization initiative and an AI data center platform effort with Nvidia. ^[39]

The flip side is that PLTR’s valuation debate is still intense, analyst targets remain widely dispersed, and headline risk—from legal disputes to political scrutiny—can move the stock quickly, particularly around the open. ^[40]
