South Dakota’s November 3, 2026 general election produced 310,298 ballots cast statewide, placing turnout squarely inside the 300K-325K bracket that now dominates trader pricing. Official figures from the Secretary of State confirm this total against 628,563 registered voters, yielding 49.37 percent participation—the lowest recorded general-election rate in the state since at least 1964 and well below the 59.4 percent of 2022. The uncompetitive U.S. Senate contest, in which incumbent Mike Rounds secured roughly 305,000 votes, aligned with this depressed overall volume. Certification scheduled for November 10 is expected to produce only minor adjustments that remain inside the same range. Late shifts in reported totals or successful challenges to ballot counts could theoretically push the final figure outside 300K-325K, though no such developments have surfaced in the post-election canvass.
