California Billionaire Tax Heads to Ballot; Tech Pushes Back
A proposed California Billionaire Tax has qualified for the November ballot after organizers reported nearly double the needed signatures, prompting major Silicon Valley pushback led by Sergey Brin and other tech figures. The state measure would impose a one-time 5% wealth tax on individuals with more than $1 billion in assets and presumes ownership based on voting or control rights, a clause that has alarmed founders who hold voting control but limited equity. Separately, hyperscaler data‑center buildouts (including the Stargate project) are facing delays and local opposition in multiple U.S. states and Europe, complicating infrastructure plans for AI companies. The Musk v. Altman trial continued in Oakland, highlighting disputes over OpenAI’s shift toward a for‑profit structure and profit‑cap changes. The newsletter also notes seed funding is increasingly concentrated in very large 'megaseed' rounds.
A statewide wealth-tax ballot measure affecting major tech founders and potential relocation decisions, coupled with data‑center buildout delays and high‑profile legal disputes over AI lab commercialization, could materially influence capital flows, infrastructure availability, and regulatory dynamics across the tech ecosystem.

Key Takeaways & Evidence Grounding
- Proponents reported they collected almost twice the signatures needed to place California’s Billionaire Tax Act on the November ballot.
- The proposed state measure would impose a one-time 5% wealth tax on individuals with more than $1 billion in assets and presumes business-entity ownership based on voting or control rights.
- Sergey Brin has spent at least $57 million on counter-measures opposing the tax and has publicly campaigned against it.
- Stargate paused plans for data centers in Norway and the U.K. and halted expansion in Abilene, Texas; OpenAI is leaning on leasing deals with providers such as Oracle, Broadcom, and CoreWeave.
- Elon Musk testified in the civil trial against Sam Altman and OpenAI, focusing on disputes about the size of OpenAI’s for‑profit arm and profit-cap arrangements.

Sergey Brin Spends $100M Fighting Billionaire Tax
Google co-founder Sergey Brin has donated an additional $20 million to Build a Better California, bringing his total spending to more than $100 million to oppose California’s proposed Proposition 40 — a one-time 5% wealth tax on roughly 200 billionaires. Prop 40 is intended to fund state healthcare programs. The article notes other tech billionaires relocating or taking steps that could limit their California tax exposure, and reports Governor Gavin Newsom has pushed for a national billionaires’ tax instead. Californians will vote on Prop 40 in November. Nvidia co-founder Jensen Huang has publicly said he is willing to pay the tax.
Silicon Valley Embraces Industrial Policy and AI Shift
At the Hill & Valley Forum and across recent headlines, prominent Silicon Valley figures signaled a shift from small‑government orthodoxy toward support for industrial policy—endorsing onshoring, military tech spending, and building AI data centers to compete with China. Jamie Dimon publicly urged use of industrial policy. The newsletter also covers OpenAI’s pivot away from consumer projects (notably killing its Sora AI video app after a contentious Disney warrant deal), a federal judge blocking a government “supply chain risk” designation of Anthropic, major venture and defense funding (Shield AI raising $2 billion; Kleiner Perkins raising $3.5 billion), and new political activity including Sen. Bernie Sanders filing an AI data‑center moratorium bill. The piece highlights tensions between tech, Hollywood, investors, and policymakers as AI commercialization, regulation, and public opinion converge.
SpaceX Ties Musk Pay to 1M People on Mars
This AI Secret newsletter (2026-04-30) highlights several tech and AI industry signals: SpaceX’s board approved a compensation plan that would grant Elon Musk large blocks of super-voting Class B shares if the company reaches a $7.5 trillion valuation and helps establish a permanent settlement of at least 1 million people on Mars, with further share awards tied to valuation and space-based data-center compute capacity. The briefing also flags Flipbook, a generative visual browser whose per-interaction compute could create heavy token consumption; the Musk v. OpenAI/Microsoft trial and its multi-hundred‑billion dollar damages claim; claims from OpenAI leadership that GPT-5.5 reduces the need for stepwise prompt engineering; and product moves such as Snapchat’s AI Sponsored Snaps. The note wraps with short industry headlines on Mistral Workflows, Google’s Pentagon AI contract, and other AI/tech policy and infrastructure items.
