History Says This Will Happen to Palantir Stock by 2028

Palantir trades at a price-to-sales ratio of 81, which the article argues leaves little room for competition or slower growth. Wall Street consensus projects year-over-year growth slowing from 93% in Q2 to 84% in Q3, 75% in Q4, and 50% next year, although the company has repeatedly outpaced prior growth expectations. The author warns that AI products from Anthropic and OpenAI could pressure Palantir and expects lackluster returns through 2028.

Analysis

The key risk is not simply that Anthropic or OpenAI can reproduce features; it is whether they can make enterprise AI deployment cheaper enough to weaken Palantir’s pricing power and reduce its role as the workflow and governance layer. If customers use foundation models as components inside Palantir deployments, the labs may expand Palantir’s addressable use cases rather than displace it. Substitution risk rises if buyers can assemble secure, production-grade systems themselves and Palantir’s customer growth, deal expansion, or pricing begins to soften. The article’s growth forecasts and valuation comparison are not independently verified here; an 81x sales multiple makes expectations and duration risk unusually important, but does not by itself establish a near-term catalyst.

Over days, the main exposure is earnings and guidance: a merely strong result may not satisfy a valuation that embeds exceptional growth. Over 1–3 months, monitor U.S. commercial customer additions and expansion, large contract conversion, and management’s outlook—not just headline revenue growth. Over 6–18 months, observe whether AI labs become substitutes or distribution partners and whether Palantir can preserve pricing and customer economics as model costs fall. The contrarian case is that repeated outperformance and high switching costs could sustain premium growth; a sharp short based only on the multiple risks another squeeze. Thesis weakens if growth and customer expansion remain robust while guidance holds; it strengthens on decelerating commercial growth, weaker deal conversion, or evidence of price concessions.

Key Decisions for Investors

• Avoid initiating an outright PLTR short solely on the article’s valuation argument. First verify the current valuation, revenue-growth trajectory, and options-implied volatility; the supplied 81x figure is a risk signal, not a timing tool.
• For existing holders, consider trimming position concentration ahead of the next earnings event if the thesis depends on continued exceptional growth. Reassess after guidance and commercial-customer/deal metrics rather than reacting to a single quarterly growth rate.
• A defined-risk bearish expression is a PLTR put spread or put-spread collar around an earnings catalyst, but only if option pricing offers acceptable cost and liquidity; avoid uncapped short exposure given the history of growth surprises described in the article.
• Track whether Anthropic and OpenAI deployments complement Palantir or replace its implementation layer. Evidence of customer-built alternatives, slower expansion, or discounting would support the bear case; broader adoption of Palantir alongside third-party models would argue against it.
