This market will resolve to "Yes" if, prior to 12:00 PM June 1, 2022 Eastern Daylight Time, the city of Cambridge, Massachusetts releases a news announcement, on the website https://www.cambridgema.gov/covid19/News, indicating that the wearing of masks is required in indoor public places. This market will resolve to "No" if no such mandate is put into place.

If the mandate is not instituted by the city of Cambridge, Massachusetts, it will not count for resolution (for instance, a TSA mandate for masks on public transportation would not count). If the mandate only applies to certain spaces (such as healthcare settings or schools), this market will still resolve to "Yes."
