A list of Worldcons and serious Worldcon bids, sorted regionally. Note that most bids' opening date in the list is when they were started; however this does not hold for actual Worldcons, sorted by their date (so their bids' start is not available here).

Bids are “failed” if they lost the vote, “abandoned” or “withdrawn” if they folded before site selection.
