His efforts are down to the wire, as there is a June 25 deadline to certify whether the proposal will be on the November ballot.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">As of Wednesday, June 17, Kalshi and Polymarket showed it was just under a coin flip on whether the tax would make the ballot.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Both prediction markets took a major dive after Bloomberg and Politico separately reported in the last week that Newsom was working to kill the tax. Before the reports, both markets were above 80%. Polymarket traders priced the odds of the initiative making the ballot at near 90%.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The markets are far more skeptical that voters will support the tax. As of Wednesday afternoon, Kalshi traders gave the proposal just over a 19% chance. Polymarket traders pegged it at just an 18% chance.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Both markets only require the tax to pass, which would require a simple majority of Californians to vote in favor of it (provided the proposal actually makes the ballot).<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Under the proposal, California residents and certain trusts with net worth of $1 billion or more would face a one-time tax for tax year 2026. The full rate would be 5% for those at or above $1.1 billion, with a phase-in for individuals between $1 billion and $1.1 billion.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The proposal has divided traditional allies of the California Democratic Party, with the SEIU-UHW, a healthcare workers union, pushing the tax. Planned Parenthood affiliates and the California Teachers Association, one of the state&#8217;s largest teachers unions, are lined up against it.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">One of the most controversial aspects of the proposal is that it would apply retroactively to billionaires living in California as of January 1, 2026.

Already, Brin has donated $82 million to &#8220;Building a Better California,&#8221; a political action committee that has backed multiple competing anti-wealth tax ballot measures. Stripe cofounder Patrick Collison donated $7 million to the effort and former <a class=\"link \" href=\"https:\/\/www.businessinsider.com\/google?utm_medium=syndication&amp;utm_source=yahoo&amp;utm_medium=referral&amp;utm_source=yahoocom\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"elm:link;elmt:article_link;slk:Google;itc:0;sec:content-canvas\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;Google&quot;}\">Google<\/a> CEO Eric Schmidt kicked in roughly $3 million more.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">All told, &#8220;Building a Better California&#8221; has brought in a staggering $129 million from just 10 donors. The group&#8217;s competing initiatives could neuter or greatly limit the proposed billionaire tax. One of their ballot measures includes a retirement-and-personal-savings measure that would prohibit new taxes on ownership or control of personal property and ban retroactive taxes. Under state law, if both initiatives secure a simple majority of votes, the one that receives the most votes would win.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Separately, Ripple Labs and Chris Larsen, its executive chairman and cofounder, each donated $5 million to &#8220;Golden State Promise,&#8221; which was set up to oppose the proposed tax.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Famed Silicon Valley investor Ron Conway donated $100,000 to &#8220;Stop the Squeeze,&#8221; another opposition group.
