This is a market about whether there will be a federal mask requirement on US domestic flights on November 8, 2022, posited by Nate Silver: https://twitter.com/natesilver538/status/1476930984931168276?s=21.

This market will resolve to “Yes”, if on November 8, 2022, all ordinary domestic airplane travellers are required by law to wear a mask that completely covers the mouth and nose while using airplane transportation. Otherwise, it will resolve to “No”.

For this market to resolve to “Yes”, the mandate must be issued by a federal agency, such as the CDC or TSA - not solely by airplane companies.

Please note, if there is a mask mandate that is applicable to all ordinary passengers but vaccinated people, it will NOT be sufficient to resolve the market to “Yes.”

Note also that the mask mandates in question do not have to be due to COVID-19.
