Will Palantir's stock move more than 10% in either direction on Tuesday, August 4, after Monday's earnings?

Palantir Technologies (PLTR) shares moved up sharply on Tuesday, August 4, 2026, with reports placing the single-day gain in a range of roughly 26 percent to nearly 30 percent, well past the 10 percent threshold in question. Multiple outlets, including CNBC and Yahoo Finance, described the advance as one of Palantir's largest single-day moves in more than two years. The rally followed second-quarter 2026 results released after Monday's close: revenue rose 93 percent year-over-year to about $1.94 billion, above analyst estimates near $1.8 billion, while adjusted earnings per share came in around $0.41, versus consensus of roughly $0.34 to $0.35. U.S. commercial revenue jumped 149 percent year-over-year to about $764 million, and U.S. government revenue rose 90 percent to about $809 million. Palantir also raised its full-year 2026 revenue guidance to a range of roughly $8.15 billion to $8.16 billion, up from a prior ceiling near $7.66 billion, citing accelerating demand for its artificial-intelligence software platforms among commercial and government customers. The results extended a multi-quarter streak of earnings beats and came amid a year marked by elevated volatility in Palantir shares tied to its AI and government-contracting growth narrative. Ahead of the report, Predict Six's community forecast had unanimously assigned 0 percent probability, across three votes, to a move exceeding 10 percent in either direction; the stock's actual Tuesday reaction substantially exceeded that threshold.
