Palantir (PLTR) Stock in December 2025: Buy or Sell After Michael Burry's Big Bet and Cathie Wood's Trims?

Published: December 9, 2025

Palantir Technologies has turned into one of 2025’s most polarizing stocks. The data‑analytics and AI specialist is up well over 100% this year and more than 2,000% since the launch of its flagship AI platform, yet it’s also facing loud warnings about a possible AI bubble, sky‑high valuation and heavy insider and institutional selling. ^[1]

In the past few weeks alone:

Michael Burry disclosed a massive put‑option position effectively shorting about 5 million Palantir shares . ^[2]
Cathie Wood’s Ark Invest has repeatedly trimmed its Palantir stake after huge gains, cutting it to roughly 3% of assets under management while still keeping it as a core holding. ^[3]
Bank of America raised its price target on PLTR to $255 even as it acknowledged valuation risks. ^[4]
Palantir reported Q3 2025 revenue growth of 63% and US commercial revenue up 121% , and announced a new AI partnership with Nvidia and CenterPoint Energy to accelerate data-center construction. ^[5]

Meanwhile, Investor’s Business Daily is framing the current moment as “2026’s Palantir Stock Debate: Defense Play or AI Enterprise Growth Machine?” , arguing that both fundamentals and technicals leave plenty for bulls and bears to fight over. ^[6]

Here’s how the story looks on December 9, 2025 — and how today’s headlines and the three articles you flagged (IBD, Motley Fool/Yahoo, and the Michael Burry piece) fit into the larger picture.

Palantir in 2025: From Secretive Contractor to AI Hyper‑Growth Story

Palantir started as a defense and intelligence software company, building platforms like Gotham for governments and national-security agencies. It now also sells Foundry and its Artificial Intelligence Platform (AIP) to corporations, positioning itself as a key AI infrastructure vendor for both the public and private sectors. ^[7]

That evolution shows up clearly in the numbers:

Q3 2025 revenue: about $1.18–$1.2 billion , up 63% year over year . ^[8]
US commercial revenue: up 121% year over year to around $397 million , now one of the main growth engines. ^[9]
Net income: roughly $476 million in Q3, with strong margins and a Rule-of-40 score over 100, signaling a rare combination of fast growth and high profitability. ^[10]
Management raised full‑year 2025 guidance and projected Q4 revenue growth around 61% , with US commercial growth still in triple digits. ^[11]

Trefis notes that Palantir’s roughly 150% move in 2025 has been driven by:

repeated earnings beats and guidance raises,
surging demand for AIP,
major US government contracts (including big Army and Maven‑related deals), and
strategic partnerships with integrators like Accenture Federal Services and Deloitte. ^[12]

At the same time, Trefis and others flag valuation as the main caveat, with the stock viewed as “attractive but volatile.” ^[13]

Q3 2025 and the AI Partnership With Nvidia

The bullish fundamental story was reinforced not just by earnings but by new strategic partnerships .

On December 4, 2025 , Reuters reported that Palantir, Nvidia and CenterPoint Energy are building a new AI-driven platform called “Chain Reaction” . Its goal is to speed up the development of power-hungry AI data centers by coordinating enabling, supply chains and construction across chip makers, utilities and data-center operators. ^[14]

Chain Reaction aims to use Palantir’s software and AI models to surface issues buried in messy real‑world data — for example, email threads hinting at vendor delays — and help stakeholders adjust schedules before problems snowball. ^[15]
The project extends earlier Palantir–Nvidia collaborations and positions Palantir as an orchestration layer for the physical AI infrastructure build‑out , not just for digital data analytics. ^[16]

This is exactly the kind of narrative powering the “AI enterprise growth machine” side of the IBD debate: Palantir as a core enabler of the AI economy rather than “just” a government contractor. ^[17]

1 Reason to Buy Palantir Stock Before 2026: Explosive AI Adoption and Long Runway

The Motley Fool / Nasdaq article “1 Reason to Buy Palantir Stock Before 2026 and 1 Reason to Sell” (also syndicated by Yahoo Finance) captures the bull case neatly: growth and runway . ^[18]

Key points from that piece and related coverage:

Palantir’s AIP lets customers embed generative‑AI agents into workflows and choose between fully automated, partially automated, or human‑assisted modes — a degree of flexibility that’s resonating with enterprises. ^[19]
Revenue growth is not only high but accelerating , with recent quarters described as Palantir’s “best yet” in terms of year‑over‑year growth. ^[20]
Even after its big run, Palantir reportedly has only about 530 US commercial customers , implying a long runway as AI adoption spreads across industries. ^[21]

Analysts and commentators see this playing out in customer reactions:

24/7 Wall St. highlights Wedbush analyst Dan Ives , who says prospective customers are “shocked” after AIP demos — a qualitative sign that Palantir’s product still has a strong wow-factor. ^[22]

AI‑driven forecasts are also leaning bullish — with all the usual caveats:

A Finbold analysis using OpenAI’s ChatGPT suggests an expected year‑end 2025 price around $225 per share , based on a probability‑weighted mix of bullish, base and bearish scenarios:
- base case: roughly $205–$235 ,
- bullish case: $260–$ 310
- bearish case: $140–$170 . ^[23]

These models assume continued 40–60% revenue growth, robust government and commercial AI contract wins, and expanding margins. They also explicitly warn that any slowdown in AI spending or a rotation away from high‑multiple tech could push the stock toward the low end of the range. ^[24]

Put simply, the “reason to buy” is that:

Palantir appears to be one of thefastest‑growing, most profitable AI software platformsin the market, with both government and commercial demand accelerating and big strategic partners (like Nvidia) leaning on its software.

For long‑term growth investors who prioritize business quality and market opportunity over near‑term valuation, that’s a compelling story.

1 Reason to Sell: A Valuation That Bakes In Years of Perfection

The same Motley Fool/Nasdaq article that praises Palantir’s growth is even more emphatic about the valuation risk . ^[25]

As of early December 2025, Palantir trades:

at roughly 115× trailing sales and
about 243× forward earnings ,

according to the analysis reproduced on Nasdaq. ^[26]

For comparison, Nvidia — itself seen as expensive — is quoted at about 24× sales and 38× forward earnings . The article notes that simply repricing Palantir’s forward P/E to Nvidia’s level (assuming earnings remain constant) would imply a very large share‑price drop. ^[27]

Other outlets echo this concern:

The Economic Times calculates Palantir’s P/E around 416 and notes the stock has already fallen about 22% from its peak near $207.52 , despite blowout revenue growth. ^[28]
AlphaSpread summarizes that Palantir trades at well over 100× annual revenue , far above typical large‑cap tech or AI peers. ^[29]
The Economist has gone as far as to call Palantir “possibly the most overvalued firm of all time” , estimating its market value around $430 billion , more than 600× its 2024 earnings and roughly 85× expected forward sales as of November 2025. ^[30]

The Motley Fool/Nasdaq article runs a thought experiment:

Even if Palantir were to sustain ~60% compound annual revenue growth for four years and hold ~40% profit margins , it might earn around $10.2 billion in profit by then.
Valued at 38× forward earnings (similar to Nvidia), that’d give a hypothetical market cap of about $388 billion — less than Palantir’s current market cap (around $420+ billion ). ^[31]

The implication: several years of very strong execution already seem priced in. Any disappointment — even just meeting guidance instead of beating it — could lead to an outsized correction.

That’s why the “reason to sell” is simple:

Palantir’s current valuation leaves little margin for error; multiple years of aggressive growth and high profitability are already implied in today’s price.

Michael Burry’s 5 Million‑Share Put Position: A High‑Profile Bearish Signal

The third key thread in today’s Palantir news cycle is Michael Burry’s big bearish bet .

Regulatory filings (Scion Asset Management’s Q3 2025 13F) showed:

put options tied to 5 million Palantir shares ,
with a notional value of about $912 million ,
alongside puts on 1 million Nvidia shares . ^[32]

Initial headlines presented this as a nearly $1 billion short position , but Burry later clarified on social media and in subsequent coverage that:

he actually paid around $9.2 million for roughly 50,000 contracts on Palantir with a $50 strike expiring in 2027 ,
giving him downside exposure equivalent to 5 million shares,
and implying he expects the stock could fall more than 70% from recent levels to make the trade really pay. ^[33]

In a MarketWatch‑covered interview, Burry explained that:

he sees the overall US stock market heading into “a number of bad years,”
regards parts of the AI trade as bubble‑like,
and criticizes Palantir specifically for an inflated valuation and heavy stock‑based compensation . ^[34]

Nasdaq and other financial sites describe Burry as “much more bearish on Palantir than on Nvidia” , given the size and structure of its PLTR puts. ^[35]

However, it’s important context — and this is exactly what the Motley Fool piece “Here’s Why You Might Not Want to Buy Into Michael Burry’s Bet on Palantir” argues — that:

the cash at risk (roughly $9.2 million) is far smaller than the notional value ,
the time horizon (options expiring in 2027) is quite long, and
Burry’s trade reflects a macro view on an AI/tech bubble , not a forensic, company‑specific fraud call like his 2000s housing‑market short. ^[36]

So Burry’s position is a meaningful sentiment data point , not necessarily a precise prediction of where Palantir “should” trade next quarter.

Cathie Wood, Ark Invest and Insider Selling: Red Flag or Profit-Taking?

Another December 2025 storyline is that big believers are selling — but not abandoning — Palantir.

Ark Invest’s Trim

The Economic Times and 24/7 Wall St. both report that:

Ark Invest has been trimming its Palantir stake throughout 2025.
After a $57 million sale of ~355,000 shares on December 4 , PLTR represents roughly 3% of Ark’s ~$16.8 billion AUM , down from 4.75–7.27% earlier in the year when it was among its top holdings. ^[37]
Ark previously sold over $185 million worth of Palantir shares in July and smaller amounts in January and November. ^[38]
Even after trims, Ark still holds $500–660 million of PLTR, and its historical trading has produced an estimated 985% gain on the position. ^[39]

The messaging here is that this looks more like rebalancing and profit‑taking after a massive run — made more urgent by volatility and AI‑bubble fears — than a vote of no confidence in the business itself. ^[40]

CEO Alex Karp and Other Sellers

The same AND piece highlights additional selling activity:

CEO Alex Karp filed to sell 585,000 shares (~$96 million) under a 10b5‑1 plan, sparking a one‑day drop of nearly 6%. ^[41]
Economic Times estimates that repeated sales by Ark, Burry’s puts and another prominent tech investor’s December 8 sale helped drive a 22% decline from Palantir’s 2025 high . ^[42]

Insider selling doesn’t automatically equal disaster — especially after a stock has risen thousands of percent — but the clustering of high‑profile sellers is feeding the “topping out / bubble risk” narrative.

Wall Street Split: From “Most Overvalued Stock” to Best‑in‑Class AI Enabler

What makes Palantir particularly fascinating right now is how polarized professional opinion has become.

On the bearish side :

The Economist famously labeled Palantir “possibly the most overvalued firm of all time,” citing a valuation of about $430 billion , more than 600× 2024 earnings . ^[43]
Economic Times points to technical overbought signals , such as an RSI around 71 in November, and warns that government revenue concentration and stock‑based compensation remain key risks. ^[44]
A string of articles from outlets like Zacks, Nasdaq and AlphaSpread argue that Palantir’s triple‑digit price‑to‑sales multiple and huge run‑up make it vulnerable if AI enthusiasm cools or growth merely slows from “insane” to “strong.” ^[45]

On the bullish side :

Bank of America just raised its PLTR price target from $215 to $255 , calling Palantir a “best-in-class AI enabler” with room to run into 2026. ^[46]
24/7 Wall St. notes that despite Burry’s puts, many analysts still view Palantir as one of the most attractive pure‑play AI software names, with earnings expected to drive the stock more than sentiment over the long term. ^[47]
Investor’s Business Daily emphasizes that generative AI creates new upside and new risks , and frames PLTR as sitting between a defense stock and a hyper‑growth enterprise AI platform , meaning valuation debates are unlikely to settle anytime soon. ^[48]

In other words, Palantir has arguably become the poster child of the AI valuation debate :

Is it an over‑hyped bubble stock priced for perfection?
Or is it the early innings of a long‑duration AI infrastructure winner whose current valuation will look reasonable in retrospect?

Reasonable investors — and professional analysts — now both occupy camps.

So Is Palantir Stock a Buy, Sell or Hold in December 2025?

Bringing together the three core articles you referenced and today’s broader news flow:

What the IBD piece adds

Investor’s Business Daily ’s “2026’s Palantir Stock Debate: Defense Play Or AI Enterprise Growth Machine?” essentially says:
- Fundamentally, Palantir looks very strong — fast growth, expanding margins, and major AI contracts.
- Technically, the stock is extended and volatile , with big moves up and down and a history of sharp pullbacks after euphoria.
- Generative AI is a huge opportunity and a source of risk: expectations might have run ahead of reality. ^[49]

What the “1 Reason to Buy / 1 Reason to Sell” article adds

The Motley Fool/Nasdaq/Yahoo piece boils everything down to a paradox:
- Reason to buy: accelerating growth, tiny commercial penetration relative to the addressable market, and a powerful AI product that customers love.
- Reason to sell: at current prices, the stock already assumes several years of near‑perfect execution, making even a small miss dangerous. ^[50]

What the Michael Burry commentary adds

The Burry‑focused article and related coverage remind investors not to blindly mimic celebrity trades :
- Burry’s puts are large in notional value but modest in cash outlay relative to his wealth.
- They express a macro view on an AI and broader market bubble , not necessarily a judgment that Palantir’s business will deteriorate.
- His time horizon (options expiring in 2027) and risk tolerance may be very different from those of ordinary investors. ^[51]

Bottom Line for December 9, 2025

Putting it all together, the December 2025 Palantir picture looks like this:

The business:
- Firing on almost all cylinders, with 63% revenue growth , 121% US commercial growth , rising profitability and new AI partnerships (like Chain Reaction with Nvidia and CenterPoint). ^[52]
The stock:
- Trading around $180+ per share , up roughly 140–150% year‑to‑date , more than 2,000% since early 2023, and valued at triple‑digit multiples of sales and earnings . ^[53]
The sentiment:
- Split between AI‑believer bulls (Bank of America, Wedbush, Ark still holding a large core position) and bubble‑watching bears (Burry, The Economist, valuation‑focused analysts). ^[54]

For potential investors, that translates into a very simple but uncomfortable trade-off:

If you believe Palantir can sustain extremely high growth for many years , continue deepening its moat, and cement itself as a must‑have AI platform for enterprises, then the stock could still work over a long horizon — even if it remains volatile.
If you are uncomfortable with extreme valuations, crowded sentiment, or the possibility of an AI-bubble unwind , Palantir is exactly the kind of name that could see dramatic drawdowns if expectations slip or macro conditions worsen.

Either way, Palantir is now a high‑risk, high‑reward AI bellwether that embodies the core question of late‑2025 markets:
