In 2022, campaigns supporting and opposing the seven ballot measures that appeared on the general election ballot amassed $724.8 million in contributions. This is an average of $103.5 million per measure, which is the highest average for California ballot measures between 2016 and 2022.
In 2022, the most expensive ballot measures were Proposition 26 and Proposition 27, with supporters and opponents receiving a combined $463.4 million. They are also the most expensive ballot measures in California from 1999 to the present. Both measures, which related to sports betting legalization, were defeated in November. Behind Propositions 26 and 27, campaigns surrounding Proposition 22, a 2020 measure related to app-based drivers and labor regulations, raised a combined total of $224.2 million.
