Palantir’s Stock Decline Reflects Broader Tech Sector Cooling

Palantir Technologies Inc. (PLTR) extended its losing streak to five consecutive trading days, with shares plummeting over 9% on Tuesday afternoon. The decline mirrors a broader retreat from high-flying tech stocks that previously drove market rallies in 2025.

Despite a 150% surge from April lows following its $1 billion quarterly revenue milestone, Palantir now faces its longest slump since March. Short-seller Citron Research compounded pressures with a $40 price target—deemed "generous" by founder Andrew Left—based on comparisons to OpenAI's $500 billion valuation.

The tech sector's pullback extends beyond Palantir. The Technology Select Sector SPDR Fund (XLK) dropped 1.5%, while AI leaders Nvidia (NVDA) and Advanced Micro Devices (AMD) fell 3% and 5% respectively. Meta Platforms (META), despite heavy AI investments, declined 1.8%.
