There's been concerns: Elon Musk has said Twitter is at risk of declaring bankruptcy, many engineering staff have been laid off, rumors of lurking technical debt that could bring down the site irrecoverably, landlords not being paid on-time, and likely more-to-come.

Resolves YES if Twitter is accessible by web browser as of market close, and any Tweet is able to be posted on the site. Otherwise NO. This market does not resolve NA.

Temporary outages do not count, and if it's unclear whether an outage is temporary or permanent the market can be extended by up to 1 week before it will just resolve NO.

Twitter is any website that refers to itself as Twitter located at either the domain twitter.com or any subdomain of twitter.com redirected to past a login step. The locator is a web browser that follows redirects, not purely a DNS mapping.

A Tweet is either a message referred to as a Tweet or a publicly-visible reply to anything currently(as of 2023-04-04) named a tweet.

A Website is a visual rendering produced in my web browser from HTML, CSS, and Javascript. So DNS, comments in the source code, outside comments by any owners of X, would not count as references to Twitter.

Description changes:

2023-07-24: A web browser is used to convert "twitter.com" to a website, not a DNS lookup.
