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 the source: the company "opened the $265 million Sands Macau in May 2004," ending "Mr Ho's 42-year monopoly over the industry."
Wikipedia states plainly "The casino opened on May 18, 2004 at a cost of $240 million," an exact match to the pin's stored date, though the fetched excerpt did not separately surface the Stanley Ho monopoly detail.
Macao News's own 20th-anniversary retrospective title, "20 years of progress: The Sands Macao story," carries a stored publish date of 18 May 2024 - the casino's 20th anniversary - corroborating the 18 May 2004 opening date via its own anniversary framing, though the domain could not be verified for direct fetch.
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.
