Recent generic congressional ballot averages from trackers including Nate Silver and Decision Desk HQ have stabilized in the Democrats +6 to +7 range, reflecting modest out-party gains typical for midterms under a Republican administration with approval near 45 percent. Fresh surveys through mid-August, such as those from YouGov/Economist and Reuters/Ipsos, show single-digit Democratic edges amid voter priorities on the economy and recent developments including renewed Iran tensions and higher gas prices that have reinforced the existing tilt. With polling volatility and sample variations keeping exact daily readings uncertain, trader consensus centers on outcomes near the current averages while assigning lower probability to sharper moves.

The difference will be calculated by subtracting the number listed for Republicans from the number listed for Democrats, or vice versa depending on who is leading.
In the event that the market only lists brackets for one party, this market will resolve to the lowest bracket for the listed party if another party is leading in the average or if the average is tied.
The party ballot share numbers for the specified date must be finalized before it is considered for this market. A date's data points will be considered finalized once the data point for the next date is made available.
This market's resolution source will be Silver Bulletin's Generic Congressional Ballot, https://www.natesilver.net/p/generic-ballot-average-2026-nate-silver-bulletin-congress-polls. Changes in the methodology by which Silver Bulletin calculates the party averages will have no bearing on the resolution of this market. If Silver Bulletin's Generic Congressional Ballot polling averages become permanently unavailable, RealClearPolitics will be used.
The resolution source reports the polling values to only one decimal point (e.g., 42.8%, 33.9%, etc.). Thus, this is the level of precision that will be used when resolving the market. In the event that the resolution source changes to allow additional decimal points, the polling average difference will be calculated by subtracting using the unrounded percentages and then rounding to the nearest tenth of a percentage point.
