TLDRs;
- Palantir surges on AI growth despite soaring valuation and insider selling.
- Michael Burry’s puts and Ark trims fuel volatility in PLTR stock.
- AI partnerships with Nvidia and CenterPoint boost Palantir’s enterprise expansion.
- Analysts split on Palantir: high growth potential versus bubble risks.
Palantir Technologies has emerged as one of 2025’s most debated stocks, attracting both fervent bulls and cautious bears.
The data analytics and AI firm has surged over 140% year-to-date, building on more than 2,000% growth since the debut of its flagship AI platform. Yet the company’s stratospheric valuation, combined with insider selling and high-profile investor activity, has fueled a heated discussion over whether Palantir is a market darling or an overhyped bubble.
Palantir Technologies Inc., PLTR
Surging Revenue and AI Expansion
Palantir’s transition from a government-focused software provider to an enterprise AI powerhouse is evident in its financials. Q3 2025 revenue climbed 63% year-over-year to nearly $1.2 billion, with US commercial revenue soaring 121% to roughly $397 million. Net income hit $476 million, signaling both rapid growth and strong profitability.
Management has raised full-year guidance, projecting Q4 growth around 61%, maintaining triple-digit growth in its commercial segment.
Strategic partnerships are a key part of this growth story. On December 4, 2025, Palantir announced “Chain Reaction,” a collaboration with Nvidia and CenterPoint Energy aimed at accelerating AI data-center development. By using AI to optimize logistics, vendor coordination, and construction timelines, the project positions Palantir as an essential player in both digital analytics and physical AI infrastructure.
Insider Moves and High-Profile Bets
Investor sentiment has been shaped by prominent market moves. Michael Burry disclosed a massive put position equivalent to 5 million Palantir shares, reflecting his broader concerns about AI sector overvaluation. Meanwhile, Cathie Wood’s Ark Invest has trimmed its Palantir stake, now representing roughly 3% of its assets under management, though the company remains a core holding.
Even CEO Alex Karp sold shares under a 10b5-1 plan, contributing to a temporary 6% drop. While these moves have raised eyebrows, experts note that Ark’s sales likely reflect profit-taking and portfolio rebalancing rather than a lack of confidence in Palantir’s long-term prospects. Similarly, Burry’s long-dated puts are a macro hedge, not a precise forecast of Palantir’s near-term performance.
Valuation Raises Alarm Bells
Despite stellar growth, Palantir’s valuation remains a contentious issue. Trailing sales multiples sit around 115×, with forward earnings multiples near 243×. Comparatively, even high-flying Nvidia trades at 24× sales and 38× forward earnings. The Economist has labeled Palantir “possibly the most overvalued firm of all time,” with a market value approaching $430 billion.
Analysts warn that several years of near-perfect execution are already baked into the stock, leaving little room for error.
This has created a stark divide in market opinion. Bears caution that any slowdown in AI adoption or failure to meet aggressive targets could trigger sharp corrections. Bulls, on the other hand, point to Palantir’s strong fundamentals, growing AI footprint, and major contracts with government and enterprise clients as evidence of sustainable upside.
Wall Street Split: Bubble or AI Leader?
Investor opinion is sharply polarized. Bank of America recently raised its price target to $255, citing Palantir as a “best-in-class AI enabler,” while outlets like AlphaSpread and Zacks highlight technical overbought conditions and concentrated government revenue as potential risk factors. Investor’s Business Daily frames the debate as a choice between a defense play and a hyper-growth AI enterprise, reflecting the broader uncertainty around the stock’s trajectory.
Ultimately, Palantir embodies the late-2025 market’s central dilemma: balancing extraordinary growth potential with extreme valuation and sentiment-driven volatility. For long-term investors willing to accept risk, the company may still represent a compelling AI growth story. For those cautious about market exuberance, Palantir’s current multiples serve as a stark reminder of the potential downside.
