A one-time wealth tax on billionaires has been proposed to potentially appear on California's ballot for the November 3, 2026 general election. You can read more about that here:https://oag.ca.gov/system/files/initiatives/pdfs/25-0024A1%20%28Billionaire%20Tax%20%29.pdf

This market will resolve to "Yes" if any proposition containing a one-time tax targeting individuals, households, or family units with wealth, assets, or net worth of at least $1 billion (USD or equivalent) passes in the named election. Otherwise, this market will resolve to "No".

If no qualifying ballot initiative is certified to appear on the official statewide California ballot as a proposition to be voted on in the stated election by June 25, 2026, 11:59 PM ET (the official cutoff date for new initiatives to be approved), or if all qualifying propositions/initiatives are removed from the ballot or amended before the election such that the main threshold drops below $1 billion, this market will resolve "No".

The primary resolution source for this market will be official information from the Government of the State of California, however a consensus of credible reporting may also be used.
