A late-November 2025 amendment to California's wealth tax proposal treats founder control as ownership, which could end founder-controlled startups in the state

Context & Ripple Effects
The amendment arrives as California’s proposed levy was already testing the state’s relationship with its wealthiest technology figures: reports said Peter Thiel and Larry Page were considering leaving California over the ballot measure. It extends that conflict from taxable economic holdings to the governance rights that let founders retain control after fundraising.
The issue also fits a broader policy-and-industry contest in which tech leaders are building political capacity to oppose the measure, including organized efforts to influence California’s tax politics. For startups, the salient question is whether control rights themselves become a tax exposure.
First-order effects
Founder-controlled companies and their founders would need to assess whether voting or other control rights are counted as ownership under the proposed tax, not just their direct economic stake.
The amendment raises immediate planning pressure around founder-control structures, especially where control is deliberately separated from cash-flow rights.
Second-order effects
Investors and startup counsel could place greater weight on governance design, because financing structures that preserve founder control may carry a different tax consequence than their economic ownership suggests.
The proposal gives technology leaders and venture stakeholders a more concrete reason to fund or join opposition to the measure, beyond its effect on billionaire balance sheets.
Third-order effects
If control is increasingly treated as taxable ownership, state tax policy could shape corporate-governance choices alongside investor and founder preferences.
The dispute points toward a broader contest over whether states can tax concentrated influence embedded in private-company control structures without weakening their appeal to high-growth company formation.
The trend: California’s wealth-tax debate is widening from the fortunes of prominent individuals to the control mechanisms that underpin venture-backed companies.

@micsolana It's so much worse than you are saying, because to pay the 50% wealth tax if you have 10X voting shares, you *first* need to pay income taxes — so you need to sell roughly 100% of your assets to pay the tax.
Come Election Day, if this proposition lands on the ballot and succeeds as written, founders throughout the industry who haven't already left California will not only be forced to sell control of their companies, many could go bankrupt. (Yes, literally). [image]
This ‘Billionare Wealth Tax’ is such an obvious self own for CA... also this pattern of marketing bills and then amending them to make them EVEN WORSE later is just an inditement of the whole system. https://www.piratewires.com/ ...
You all use Uber, DoorDash and every other tech innovation made here but now you want the creators of these services to go bankrupt doing in?? That math doesn't math. Everyone that is potentially touched by this will now leave and all that will result is a massive hole in
So the political representatives of Silicon Valley co-signed a tax plan that would require virtually every startup founder to leave the state if their company becomes successful enough. Upon learning their plan would have such a catastrophic outcome, they changed nothing.
Fun fact, I used to blog back in the day Here's my 2009 post on CA as one of the highest taxed states with the lowest ranked quality of services: https://swooshing.wordpress.com/ ... TLDR, California has been the most wasteful and most corrupt of all the 50 states for a lonnnnggg…
The architects of California's “Billionaire Wealth Tax” ballot proposition quietly amended language in their proposal which, if successful, would permanently end the concept of founder-controlled startups in the state — a technology industry kill switch. https://www.piratewires.c…
Always with the threats to leave the state. — Since states are so onerous, you have to ask why these people don't bugger off to Somalia where government oversight is pretty non-existent.
