A week ago, Twitter changed their logo to be a black stylised X on a white background. There has been a sutble update to the look of this logo, but it is still an X.

At present, the market believes that there is a very high chance that this logo will stick around for a while - traders think there's more than a 90% chance that the logo will last until the end of August:

Will this new X logo last until 21:00 BST on Thursday 31st December (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.
