Flagged:THE TRAP IN THIS STORY: Nebius's $40B in customer commitments and its 5GW year-end-2026 power target are company-wide figures from its own August 2026 reporting — neither is the size or the value of the Palantir partnership. The 6-K and every outlet checked agree that no dollar figure and no duration were disclosed for this deal specifically, and every card and caption keeps that distinction explicit rather than letting the company-wide numbers imply a deal size. dateBuilt is the day after the 8 September announcement the set covers; the artifact printed no build date of its own.
