Palantir Technologies Inc. (NASDAQ:PLTR) tumbled to a fresh 52-week low on Thursday, extending a seven-session losing streak and wiping out roughly $15.4 billion in market capitalization. The data analytics firm's stock slid 5.3% to $107.50 by late morning, with an intraday low of $106.40, bringing its market value to approximately $276.5 billion. The decline marks a stark reversal from the stock's 52-week high of $207.52, when the company was valued at around $534 billion.
Valuation Compression Accelerates
The selloff has dramatically compressed Palantir's valuation multiples. At its peak, the stock traded at nearly 70 times projected 2026 sales. Following Thursday's drop, that multiple has fallen to approximately 36 times estimated 2026 revenue of $7.65 billion to $7.66 billion. The company's price-to-earnings ratio stood at roughly 121 in morning trading, according to MarketWatch, down from even higher levels earlier this year.
Wolfe Research analyst Alex Zukin, while acknowledging Palantir's strong product-market fit, has maintained a Peer Perform rating due to valuation concerns. In a recent note, Zukin flagged that Palantir was trading at 30 times 2027 revenue and 65 times earnings, levels he considers elevated even for a high-growth enterprise software company.
Strong Fundamentals Amid Market Skepticism
Despite the stock's slide, Palantir's first-quarter results were robust. The company reported revenue of $1.633 billion, an 85% year-over-year increase, with an adjusted operating margin of 60% and adjusted free cash flow of $925 million. Management also raised its full-year sales guidance in the same report. CEO Alex Karp declared in May that Palantir is "in a category of our own," but investors have grown increasingly skeptical this month as the stock moved in tandem with interest rate concerns and broader software sector valuations.
Impact on Passive ETF Holders
Palantir's decline is now registering in major exchange-traded funds. According to TradingView, Palantir represents approximately 1.17% of the Invesco QQQ Trust (NASDAQ:QQQ), a stake worth about $5.61 billion, and 0.41% of the SPDR S&P 500 ETF Trust (NYSEARCA:SPY), valued at $3.18 billion. Thursday's 5.3% drop alone erased roughly $466 million from those two ETFs combined. While the daily impact may appear modest, the cumulative effect over the stock's seven-session losing streak is more pronounced. Barron's noted Wednesday that Palantir shares are facing their steepest monthly decline in five years, having slipped below a key technical support level.
Broader Market Context
The selloff in Palantir reflects wider market pressures on technology stocks. Reuters reported that software shares fell 1.6% earlier Thursday, weighed down by concerns over spending and the potential for further Federal Reserve rate hikes. "There is still a risk that the Federal Reserve delivers a rate hike later this year," Michele Morganti, senior equity strategist at Generali Investments, told Reuters. Palantir's high valuation makes it particularly sensitive to rising interest rates, which discount future cash flows more heavily.
With the stock now down 36% year-to-date in 2026, investors are closely watching whether Palantir can regain its footing or if the AI-fueled rally that once propelled it is fully exhausted. The company's next earnings report will be a key test of whether fundamentals can support the stock at current levels.
