Private Superforecasting Workshop and belikewater ask:

When will a SARS-CoV-2 variant other than Delta next represent more than 70.0% of total COVID-19 cases in the US?

The Delta variant of SARS-CoV-2 (B.1.617.2) became the dominant variant in the United States over the summer of 2021, and there are fears that another, potentially more dangerous, variant could follow (New Atlas, Newsweek). The CDC estimates proportions of SARS-CoV-2 lineages circulating in the United States, grouped in two-week intervals, here: https://covid.cdc.gov/covid-data-tracker/#variant-proportions. For the period ending 17 July 2021, the Delta variant and three sublineages (e.g., AY.1) represented a combined 83.5% percent share of COVID lineage in the US as of the launch of this question. Data from the “Nowcast” option would count, and Delta sublineages would not count.
