Palantir Stock Falls 25% as CEO Alex Karp Blames "Market Manipulation." Is It Time to Buy?

Palantir shares have fallen about 25% from an early‑November high after famed hedge‑fund manager Michael Burry disclosed a large short position—roughly 66% of his $1.4bn portfolio in put options—prompting CEO Alex Karp to call the activity market manipulation on CNBC. The company’s AI offerings (AIP, Foundry, Gotham) and nine consecutive quarters of accelerating sales underpin strong operational momentum, but the stock trades at an extreme multiple (around 125x sales at the peak and ~102x today), well above the next S&P peer at ~32x, implying shares could fall another ~66% and still be the most expensive by price‑to‑sales. Given the disconnect between solid fundamentals and a stretched valuation, the article advises avoiding meaningful exposure or keeping positions very small due to a skewed risk‑reward profile.

Analysis

Palantir shares have declined roughly 25% from a record high in early November after hedge fund manager Michael Burry disclosed a concentrated short position — roughly 66% of his $1.4 billion portfolio in put options — that prompted CEO Alex Karp to publicly decry the activity as market manipulation on CNBC. The disclosure has amplified investor scrutiny and helped drive a moderately negative market tone despite recent operational momentum. Palantir’s business fundamentals show continued strength: its AIP platform (launched April 2023), Foundry and Gotham offerings underpin nine consecutive quarters of accelerating sales and recognition from Forrester in machine-learning and AI decisioning software. Management emphasizes a move from prototype to production as its competitive thesis in enterprise AI, supporting expectations for continued revenue growth. Valuation, however, is the primary constraint: the stock traded near 125x price-to-sales when Karp commented and remains at approximately 102x after the decline, far above the next S&P 500 peer at ~32x; the article notes shares could fall another ~66% and still be the most expensive by that metric. Given this disconnect between strong fundamentals and extreme multiple, the risk-reward is skewed toward downside, prompting the author and shareholders to recommend avoiding material positions or keeping holdings very small.

Key Decisions for Investors

• Avoid initiating meaningful long exposure to PLTR given an extreme ~102x price-to-sales multiple and asymmetric downside risk, consider only small, size-constrained positions if bullish
• If currently long, reduce position size or implement explicit downside protection because options-driven short interest (e.g., Burry's disclosed puts) can amplify volatility
• Monitor near-term catalysts — quarterly sales guidance, AIP adoption metrics and any shifts in options/short positioning — and prefer hedged or derivative strategies over outright buys until valuation compresses or fundamentals materially exceed current market expectations
