November 2026 General Election

Last Modified: October 5, 2026

Below are lists of the top 10 contributors to committees that have raised at least $1,000,000 and are primarily formed to support or oppose a state ballot measure or a candidate for state office in the November 2026 General Election.

The lists do not show all contributions to every state ballot measure, or each independent expenditure committee formed to support or oppose a state candidate, only those committees that have raised $1,000,000 or more and have at least one contributor of $10,000 or more.

For itemized contribution and expenditure reports on state ballot measures, go to the CA Secretary of State’s Ballot Measure.

For itemized contribution and expenditure reports on state candidates, go to the CA Secretary of State’s Candidate.

*A contributor whose name is marked with an asterisk made a contribution to a committee that simultaneously supported or opposed more than one potential ballot measure for the same election. Because of this, it is not possible to determine the amount of the contribution that was spent specifically on the campaign for any particular measure. In these cases, the contributions are listed for each ballot measure the committee has been formed to support or oppose. This results in the same contribution appearing multiple times - once for each ballot measure the committee supports or opposes.

The top 10 lists reflect the most recently available data. During the 90 days before an election, the FPPC makes every attempt to ensure that the lists are updated within one business day of receiving new information. Otherwise, the top contributor lists are updated weekly.
