California Democrats currently hold 43 of the state’s 52 House seats following 2024 gains. Voters approved Proposition 50 in November 2025, enacting a mid-decade redistricting map projected to deliver Democrats a net gain of three to five seats by shifting boundaries in their favor and reducing the number of competitive or Republican-leaning districts. The June 2026 top-two primaries have produced several Democrat-versus-Democrat general-election matchups in safe seats alongside a small number of targeted contests, including those involving Republican incumbents David Valadao and retiring Darrell Issa. With the November 3 election weeks away, trader consensus at 48 seats reflects expectations that the new lines will produce the upper end of projected Democratic gains while limiting Republican holds.
