Estimated: NIO[5] has not set a date; the bidding rules ask host cities for "a continuous 10-day available window between December 1 and December 31, 2026", so the window's last day is used as the placeholder under the span rule.NIO will hold NIO Day 2026, its biggest annual event, in Wuhan after the city won a user vote on 18 July 2026; the bidding rules require a 10-day window in December 2026 and no exact date has been announced.
