    Spread cost

    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.

What to track next

  • Verify the resolution source on this page — exchange feed, official release, news consensus — before treating any move as new information.

Verification actions only — never trade recommendations.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.

Market Description

This is a market on whether there will be fewer than 1,000 daily COVID-19 cases in the U.S. on any date from May 19, 2021 to September 1, 2021. The resolution source for this market will be the CDC’s count for the number of new daily COVID-19 cases, as displayed on their COVID Data Tracker (https://covid.cdc.gov/covid-data-tracker/#trends_dailytrendscases). This market will resolve to “Yes” if the daily count for total new cases falls below 1,000 for any date from May 19, 2021 to September 1, 2021. Specifically, at 8:00 PM ET each day from May 20 to September 2, 2021, the daily case total for all previous days will be checked (e.g. on June 15, case counts for all dates from May 19 to June 14 will be checked). If that count is under 1,000 at the time of any one of those checks, this market will resolve to “Yes”. Otherwise, this market will resolve to “No”. Unusual Cases: - If the CDC website is down at the time of the final check, market resolution will be delayed until the website is restored, or if it is not restored within 48 hours, this market will resolve to 50-50. - If, at the time of a check, data is unavailable for any of the dates being checked, only dates for which there is data will be considered (e.g. if on the June 15 check, there is no data for the date of June 10, only data from May 19 to June 9 and June 11 to June 14 will be considered). If data is not available for any of the dates from May 19, 2021, to September 1, 2021, within 48 hours of the final check (by September 4, 2021, 8:00 PM ET), this market will resolve on data from dates for which data is available. Update: The market title has been updated to "Will the US have fewer than 1000 COVID-19 cases on any day on or before September 1?" to more clearly reflect the rules.
