Resolves YES if after the 2026 United States elections members of the Republican party have won at least 51 seats in the Senate, or 50 seats with a Republican Vice President for tie-breaking purposes. Resolves NO otherwise.
If a politically independent/third-party senator is elected, they would count as a Republican for the purposes of this market if they are widely expected to caucus with the Republican party.

Spending on the senate and house races. Republican advantages.

House, $1M
Field-heavy: ~2–4 turnout points in that district
Normal mix: ~0.3–1 point
TV pile-on in a hot race: ~0
Senate, $10M
Small state, field-heavy: ~1–5 points
Medium state, mixed: ~0.2–1 point
Large state, mixed: ~0–0.2 point
Buying 5 extra turnout points with mixed modern spend you are closer to $5–15M in a House district and $50–150M+ in a large Senate state. In top 6 senate races about +1-5 pts. Republicans with $1.4 billion should be able to put $20 million into the key 35 house races.
Kamala Harris had 4% polling advantage in 2024.
In the primaries there were 10-20 point polling errors.
@brianwang “TV ads paid for by campaigns (and associated federal committees) get TV time that cost roughly 1/3rd what it costs for Super PACs (like Paxton’s Super PAC, MAGA Inc. or America PAC).”
Just because they are spending more doesn’t mean they are getting more ads
Talarico has a lot of money himself. Paxton needs these outside super pacs

@AndrewG when do you decide to resolve? If a republican changes to caucus with dems on 30 November will that mean democrats win if it takes them from 50 to 51
