- Palantir Technologies Inc. (NASDAQ: PLTR) is growing revenue at an unusually fast rate, but its valuation leaves little room for weaker-than-expected growth. With shares at $188.75 and the company valued at roughly $461 billion, investors are paying a substantial premium for its artificial intelligence growth story.
Palantir's Revenue Growth Is Hard to Ignore
Palantir's latest financial results show why the stock continues to attract investors despite its valuation. The company generated $1.935 billion of revenue in the second quarter of 2026, up 93% from a year earlier. Revenue for the first six months of the year increased 89%.
The strongest part of the business remains the US market. US revenue jumped 115% year over year to $1.573 billion during the second quarter. Within that figure, US commercial revenue surged 149% to $764 million, while US government revenue increased 90% to $809 million.
That commercial growth is particularly important because investors have increasingly focused on whether Palantir can expand beyond its traditional government customer base. The company closed 220 deals worth at least $1 million during the quarter, including 98 deals of at least $5 million and 73 worth at least $10 million.
Total contract value reached $3.373 billion, a 49% year-over-year increase. US commercial remaining deal value also climbed 124% to $6.238 billion.
Palantir has also become substantially more profitable as sales have accelerated. GAAP operating income reached $912 million in the second quarter, representing a 47% operating margin. Adjusted operating income was $1.194 billion, while adjusted free cash flow reached $1.22 billion, representing a 63% margin.
The company's full-year outlook reflects continued confidence. Palantir expects 2026 revenue of $8.15 billion to $8.158 billion, implying growth of roughly 82% from the prior year. It also expects adjusted free cash flow of $4.5 billion to $4.7 billion. Third-quarter revenue is projected at $2.16 billion to $2.164 billion.
Those numbers help explain why Palantir remains one of the stocks investors are watching closely as the artificial intelligence investment cycle expands. The broader AI market is also moving into a phase where investors are increasingly demanding evidence that massive technology spending can translate into durable revenue and profits.
The Valuation Is the Biggest Problem
The difficulty for investors is that Palantir's stock price already reflects a large portion of that growth opportunity. Shares closed at $188.75 on Oct. 2, giving the company a market capitalization of about $461 billion. Yahoo Finance's latest valuation data puts Palantir at roughly 163.9 times trailing earnings, 85.5 times forward earnings, and more than 80 times sales.
Using Palantir's own 2026 revenue guidance, the stock is valued at roughly 56 times expected 2026 sales. That is an extraordinary multiple, even for a company growing revenue at more than 80%. The valuation therefore creates a different investment equation from simply asking whether Palantir is a good business. It clearly has strong growth, expanding margins and significant cash generation. The more difficult question is whether those results will remain strong enough for long enough to justify the price investors are paying today.
Wall Street's expectations illustrate the challenge. The average 12-month price target is around $196, according to MarketBeat, only modestly above Palantir's latest closing price. Investing.com puts the average target at approximately $195.57.
Several analysts remain considerably more bullish. UBS recently raised its target to $250, while DA Davidson also has a $250 target. But targets range widely, showing how sensitive the valuation is to assumptions about future growth and profitability.
There is another factor investors should monitor: stock-based compensation. Palantir recorded $466.8 million of stock-based compensation during the first six months of 2026, up from $315.3 million a year earlier. The company had another $916 million of unrecognized RSU-related compensation expense at June 30.
That does not negate Palantir's strong cash generation, but it matters when assessing per-share value and dilution over time.
So, is Palantir stock a good buy?
For investors focused on the long-term AI software opportunity, the company's growth profile remains compelling. Revenue is accelerating, US commercial demand is expanding rapidly, and profitability has improved dramatically. The business is also generating substantial cash rather than relying solely on an expectation of future profits.
The valuation, however, makes Palantir a much harder stock to buy aggressively at $188.75. At more than 50 times projected 2026 revenue, the market is already assuming that exceptionally high growth will continue.
That leaves Palantir looking more attractive as a high-growth business than as a conventionally valued stock. Investors willing to accept substantial valuation risk may still find the long-term opportunity compelling, while more valuation-conscious investors may prefer to wait for either stronger earnings growth or a lower entry price.
The key test from here is simple: Can Palantir continue growing fast enough to make today's enormous valuation look reasonable in retrospect? The next several quarters will provide increasingly important evidence.
