Palantir Technologies (NASDAQ: PLTR) experienced its most significant single-day rally since February 2024 on Tuesday, with shares closing at $162.66, up 29.45%. The stock gave back some gains in after-hours trading, slipping 1.93% to $159.52.
The surge added approximately $88.8 billion in implied equity value, driven by robust second-quarter results and an upward revision to the company's full-year outlook. The revenue guidance midpoint increased by $498 million, translating to roughly $178 in market value for every $1 increase in projected 2026 sales.
Strong Q2 Performance
Revenue for the second quarter rose 93% year-over-year to $1.935 billion, surpassing Wall Street expectations by 7.5%. U.S. commercial revenue surged 149% to $764 million, while U.S. government revenue climbed 90% to $809 million. Adjusted earnings per share came in at $0.41, 17.1% above consensus.
The company's adjusted operating margin expanded to 62%, up from 46% a year earlier, and adjusted free-cash-flow margin improved to 63% from 57%. GAAP operating margin reached 47%, even after accounting for $265 million in stock-based compensation, which represented 13.7% of revenue, down from 15.9% in the prior year.
Guidance Raised
Management lifted its 2026 revenue outlook to a range of $8.150-$8.158 billion, a 6.5% increase at the midpoint. U.S. commercial revenue is now expected to exceed $3.424 billion, up $200 million. Adjusted operating income guidance was raised by 10.1% to a midpoint of $4.893 billion, while adjusted free cash flow guidance increased 7% to a midpoint of $4.6 billion.
Third-quarter revenue guidance of $2.162 billion came in 8.1% higher than consensus estimates.
Market Reaction and Valuation
Investors rewarded the stock with a valuation of approximately 47.9 times the updated 2026 revenue midpoint and 84.9 times projected adjusted free cash flow, based on the company's second-quarter basic share count.
The rally coincided with a 2.59% advance in the Nasdaq Composite, as technology shares broadly gained. Trading volume reached 174.5 million shares, 4.2 times the 65-day average.
Analyst Perspectives
CEO Alex Karp highlighted that demand for "AI sovereignty" has "now been unleashed." Emarketer analyst Jacob Bourne called Palantir the "clearest counterexample" to claims that enterprise AI remains stuck in the pilot phase.
Contract metrics reinforced this view: total contract value rose 49% to $3.373 billion, and remaining deal value for U.S. commercial surged 124% to $6.238 billion.
However, some analysts remain cautious, citing concerns about international expansion and a valuation that leaves little room for error. The U.S. accounted for over 80% of quarterly revenue, with a nearly equal split between government and commercial contracts.
Looking ahead, investors will watch whether earnings revisions can sustain Tuesday's move above $143.28. Early after-hours trading indicated profit-taking emerged quickly.
