Wide spread — 100.0¢
Bid-ask spread is wide enough that intraday moves overstate any tradeable advantage. Most of the headline pp move would be eaten by spread on a market order.

1Market Description
This is a market on whether 170 million people in The United States of America will have initiated vaccination, according to the CDC COVID tracker, by the resolution date, June 10, 2021, 8:00 PM ET. This market will resolve to "Yes" if 170 million people or more are listed as having received their initial dose of vaccination by the resolution source. This only concerns the first dose of vaccination. For vaccines requiring two doses for inoculation, this market considers only the first dose as having initiated vaccination. This market will resolve to "No" if, for any reason, fewer than 170 million people have initiated vaccination by the resolution date. The resolution source for this market will be the official data published by the CDC available at https://covid.cdc.gov/covid-data-tracker/#vaccinations. This market will resolve according to the data as available immediately at the time of resolution, and resolution will not be delayed for the purpose of waiting for updated data from a specific date.
