Wall Street Issues “Sell” Alert: 2 AI Stocks Predicted to Plummet 55% as Valuations Decouple from Reality
The artificial intelligence gold rush of the mid-2020s may be hitting a formidable wall. Despite a surge in retail enthusiasm and a broader market recovery, a growing chorus of Wall Street analysts is sounding the alarm on two prominent AI players: Palantir Technologies and Fastly.
According to recent research notes, specific price targets suggest these stocks could lose more than half of their current market value. While both companies have delivered impressive growth figures, the primary concern is a “valuation disconnect”—where stock prices have soared so far beyond fundamental earnings power that a correction isn’t just possible, but statistically probable.
1. Palantir Technologies (PLTR): The Valuation Trap?
Palantir has long been a retail favorite, particularly as its “Artificial Intelligence Platform” (AIP) gained traction within the enterprise sector. However, the numbers behind the hype are starting to worry institutional heavyweights.
The Bear Case:
- Extreme Multiples: As of late March 2026, Palantir is trading at approximately 84.1 times forward earnings. For context, this is nearly triple the average multiple of the broader S&P 500 tech sector.
- The “Underperform” Rating: Jefferies analyst Brent Thill has maintained a stark $70 price target on the stock. With PLTR currently trading significantly higher, this implies a potential 55% downside.
- Disconnected Fundamentals: Analysts argue that while the company is profitable, its current growth rate does not justify an 80x+ multiple, leaving the stock vulnerable to even a slight “miss” in future earnings reports.
2. Fastly (FSLY): Execution and Competition Risks
Fastly, known for its edge cloud platform and high-speed content delivery, has attempted to pivot heavily into AI-driven security and edge computing. While the vision is bold, the execution remains under scrutiny.
The Bear Case:
- Execution Lags: Unlike Palantir, which has shown consistent GAAP profitability, Fastly continues to struggle with consistent bottom-line execution.
- Crowded Space: The AI-edge sector is becoming increasingly commoditized, with giants like Cloudflare and Akamai squeezing margins.
- The Valuation Gap: Analysts see Fastly carrying “double risk”—the high valuation common in the AI sector paired with the execution risk of a company still trying to find its definitive competitive moat.
The Wider Context: The $1 Trillion Software Wipeout
This warning comes on the heels of a turbulent start to 2026. Earlier this year, software stocks saw a massive $1 trillion contraction in market value. The primary driver was a sudden realization among institutional investors that while AI is transformative, it is also disruptive to existing software-as-a-service (SaaS) business models.
Many legacy companies are finding that AI is not an “add-on” they can easily monetize, but a replacement technology that could cannibalize their core products.
Frequently Asked Questions (FAQs)
Q: If these companies are growing, why is Wall Street saying “Sell”?
A: Growth alone doesn’t make a stock a good buy. If a company’s stock price doubles while its earnings only grow by 20%, the stock becomes “expensive.” Analysts believe the current prices factor in a “perfect” future that these companies may not be able to deliver.
Q: Should I sell my Palantir shares immediately?
A: Stock ratings like “Underperform” are based on a 12-month outlook. Investors should review their own risk tolerance and entry price. Some long-term “bulls” believe Palantir’s long-term government and commercial contracts will eventually justify the price, but the near-term volatility is expected to be high.
Q: What could cause these stocks to rebound instead of drop?
A: A significant “beat and raise” in the next earnings cycle, a major new government contract (for Palantir), or a successful acquisition could reverse the downward sentiment.
