US Midterms 2026

Senate races priced by prediction markets, state by state.

Midterms coverage

2 pieces so far. The rail is not padded with loosely-related politics coverage: a hub that pads reads as a hub with nothing to say.

Races by state

This table is Senate races only. Governor races are priced state by state on the same venue and are not shown here.

50 states; 33 appear here. 16 have no Senate market we could find, and this table does not tell you whether that means no contest or a contest nobody is pricing: the roster it would be checked against is not filled, so "no market" is a claim we can make and "no race" is not. Oregon has a market, but under $10,000 has changed hands in it since it opened, which is our floor for treating a price as readable at all.

Trading in the seven days to 12 August 2026

15 races, ordered by volume in that window rather than by lifetime totals. A market's whole history says where interest has been; that week says where it was.

Lifetime and 24 hour volumes are shown on wider screens.

No trading in that window

In most of these the price already says why.

Some races price a named candidate, others price a party. That is the market's own framing, not ours: where a leg names a party rather than a person, it usually means no candidate has been settled on yet. We show whichever the market uses.
