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.
Berlin's[2][4] own press release fixes the day the decision landed: "Im laufenden Vergabeverfahren für das Internationale Congress Centrum (ICC) haben das Land Berlin und die als Bestbieterin hervorgegangene Projektpartnerschaft Quartier ICC heute, am 2. September 2026, eine Exklusivitätsvereinbarung unterzeichnet." That meets the city's hope of a decision before the end of 2026, so the year-end placeholder is replaced by the signing date; the ground-lease contract itself follows, with exclusivity running "bis zum 30. Juni 2027".
The Senate Department for Economic Affairs, the department running the tender, names the day in its own release - "heute, am 2. September 2026, eine Exklusivitätsvereinbarung unterzeichnet" - which is what the pin was waiting for and retires its year-end placeholder. It also bounds what follows: "Damit erhält die Projektpartnerschaft bis zum 30. Juni 2027 Exklusivität für das ICC und das dazugehörige Parkhaus."[1]
Wikipedia confirms a June 2026 "official recommendation for a proposal to reuse the building," noting the ICC revival "is still in development" rather than finalized, consistent with the pin's own "estimated" end-of-2026 decision target rather than a firm date.
Berlin's[2] Senate Department for Economic Affairs page, the city's own economic-development portal, did not surface specific ICC content when checked, making this a weaker, tangential reference resting mainly on the department's general authority over such redevelopment decisions rather than a direct confirmation.
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. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
