Palantir Falls 7% as AI Software Stocks Shed $260 Billion in Broad Selloff

Palantir Technologies shares tumbled 7.22% on October 16, dropping to $186.70 and erasing 12.75% from their 2026 peak, as a sector-wide rout hammered high-multiple AI and enterprise software names. Snowflake sank 8.47% and Super Micro cratered 9.86% in the same session, while the broader Nasdaq fell 2.15% in what analysts described as its worst week since June. Enterprise software bore the brunt of the selling, with ServiceNow also off roughly 5% and Salesforce sliding 4%, as investors dumped richly valued AI-linked equities amid spreading concerns over AI financing and debt levels in the neocloud space.

The catalyst for the day's weakness was Fed Chair Kevin Warsh, who offered no rate signal during remarks in Bangkok, causing markets to slash the probability of an October rate cut to 15% from 28%. That repricing hit growth stocks hardest, and the VIX spiked 24% to 20.41. Geopolitical pressure added to the risk-off tone after Iran sank a container ship in the Strait of Hormuz, sending Brent crude surging 3.44% to $109.56 and drawing capital toward energy and away from tech, which fell 3.03% as a sector.

Analyst sentiment on Palantir remained broadly constructive even as the stock fell. Baird raised its price target to $250 from $200 and maintained an Outperform rating, while Mizuho lifted its target to $245. Phillip Securities moved in the opposite direction, downgrading the stock to Neutral from Buy with a target of $215. Institutional buyers had been active ahead of the slide: iShares Expanded Tech-Software ETF purchased $42.7 million in additional Palantir shares on October 14, and pre-market volume on the 16th ran above 1.8 million shares.

The selloff came despite Palantir's strong fundamental backdrop. The company's own guidance calls for 82% revenue growth in 2026 and U.S. commercial revenue growth exceeding 134%, both figures raised from earlier in the year. Second-quarter 2026 revenue had already grown 93% year over year. The stock carried premium valuation metrics heading into the session, with a price-to-sales ratio of 40.82 and a price-to-earnings ratio of 178.79, leaving it exposed when risk appetite deteriorated.
