The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Happened as dated, per 1oaklasvegas.com: "…ion Allegiant Stadium. Sphere Las Vegas opened on September 29, 2023, with U2: UV Achtung Baby Live…"
The Las Vegas Review-Journal, published 29 September 2023, reports the Sphere CEO "sidesteps U2 questions" and says opening dates were "being reviewed, pending progress" on the $2.18 billion project, showing real-time uncertainty about the exact opening around the pin's second-half-2023 timeframe.
USA Today's own headline, "U2 set to open Sphere in Las Vegas on September 29," published 24 April 2023, supports the pin's underlying claim that the Sphere was slated to open in 2023, though the article itself could not be retrieved to confirm further detail.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
