Palantir Technologies (PLTR) and Nebius Group (NBIS) have joined forces in a partnership that directly supports both companies' growth stories. Palantir gets a compute partner that can support its push into sovereign AI, while Nebius gains access to a prominent enterprise distribution channel through Palantir. That makes the deal appear straightforward and mutually beneficial on paper. Still, both stocks face growing investor skepticism. Palantir’s valuation remains a major point of debate among investors, and Nebius still needs to show that its capital-heavy build-out will eventually lead to durable profitability.
