Money vs. market

Two separate indicators — not a single WhoDonated win percentage. Fundamentals reflect seat lean and incumbency; the money signal reflects who has raised more in public FEC filings so far this cycle.

Fundamentals

36%Dem. win signal

Prior lean about 53% Democratic two-party share, plus incumbency and the national midterm environment.

Money signal

43%Dem. win signal

Democratic share of two-party receipts is 54% in the FEC cycle totals we score.

Polling averages appear in their own section below — never fused into these meters. Prediction-market odds appear only after we have written permission. Kalshi is not shown.
