Why a longtime skeptic of Palantir’s stock is finally saying it’s time to buy

A longtime bearish analyst has turned constructive on Palantir, arguing that the company's total addressable market may expand well beyond current expectations while its business model should help it defend its position against competitors. The shift is notable precisely because it comes from a persistent skeptic rather than a longstanding bull.

The market relevance here is less about the upgrade itself than about what it signals. Analyst rating changes can influence sentiment and flows, particularly in a stock with a strong retail following and a premium valuation. When a critic changes stance, it can prompt investors to revisit their own assumptions about growth durability and competitive moats.

What to watch: whether the analyst's thesis on market expansion is validated by future contract wins and revenue disclosures, and whether other skeptics follow. A single upgrade is not confirmation — it is a hypothesis. For observers, the key question is whether Palantir's results over coming quarters support the more optimistic view of its opportunity, or whether the stock's valuation already reflects it.
