<content type="text">On 20 March 2025, at Nvidia's Quantum Day, Huang walked the remark back: "This is the first event in history where a company CEO invites all of the guests to explain why he was wrong" (CNBC). He named no revised range, so there is no new dated claim to track. This one stands as stated and resolves on its own criteria.</content>

<content type="text">Captured at seed, 19 months after the remark. Real-world consequence worth noting for context (not evidence toward the verdict): the comment briefly wiped tens of billions of dollars off publicly traded quantum companies' market capitalisation the same week, and Huang has since visibly softened the framing at subsequent public appearances -- a check-in for the desk to track is whether he has ever named a revised range, which would be a genuine restatement worth logging as its own event.</content>

<content type="text">Resolves by 2040-01-06 (+30 day grace). Criteria: A genuinely hedged range, not a point claim, so it is tracked at both ends rather than forced into one deadline. EARLY-END check (this claim's primary resolves_by, 15 years out): if a quantum computer has, by 6 Jan 2040, solved a problem of real commercial or scientific value faster or cheaper than the best available classical alternative -- independently verified, not a vendor's own benchmark -- that falsifies even Huang's optimistic bound (NOT_VERIFIED: he was wrong on the early side too). If no such result exists by then, log a check-in and continue tracking toward the LATE-END gate, 6 Jan 2055 (30 years): if by then still no such result exists, that falsifies the claim from the other direction (NOT_VERIFIED: even the generous bound was too generous). VERIFIED only if the first genuine instance lands inside the window itself, closest to the ~20-year midpoint he named as the figure most people in the field would actually believe.</content>
