Twitter have changed their logo from the old blue bird to a black stylised X on a white background. Musk Tweeted this as the change happened:

Will this new X logo last until 21:00 BST on Monday 31st July (the close time of this market)?

Resolution notes;

• I will be looking at the logo on the top left of the site when I view https://twitter.com/home while logged in. If there is no longer a logo in that particular part of the page, I will use my judgement to judge what counts as the site's logo.

• If the logo is changed back to the blue bird or anything else which isn't an X, this market resolves NO, even if the change is temporary.

• If the logo is changed to something else which is still an X, this will still resolve YES

• If there is no logo on the site and it is impossible to determine what Twitter's logo is at the time that this market closes, I will resolve to N/A

• By "Twitter" I mean the service that we currently know as Twitter. If the name of the service changes, that does not affect this market.
