A Google founder has more than doubled his financial contribution to the fight against a proposed wealth tax in California. New filings with the state show that former Alphabet president Sergey Brin donated $25m to a Super Pac dedicated to blocking the tax on top of $20m he had already given.
Brin is not alone among Google’s top brass in upping his financial stake in the campaign against the ballot proposal. The company’s former CEO Eric Schmidt donated $1.02m, adding to a previous $2m contribution.
The tech titans are battling the California Billionaire Tax act, often referred to simply as the billionaire tax. It’s a proposed ballot measure that would require any California resident worth more than $1bn to pay a one-off, 5% tax on their assets to help cover education, food assistance and healthcare programs in the state. It’s sponsored by the Service Employees International Union-United Healthcare Workers West, and is still in the signature-gathering phase.
If the measure reaches the ballot and gains voters’ approval, the tax would apply to billionaires based on their residency as of 1 January 2026. For Brin, worth about $247bn, the bill would likely be upwards of $12bn. That stipulation appears to have caused him and several other billionaires to leave California at the end of last year. Brin relocated to a $42m estate on the north-eastern shore of Lake Tahoe in Nevada, and his Pac donations show Reno as his address. Schmidt’s filings show his address as West Hollywood.
The Super Pac that Brin and Schmidt most recently donated to is called Building a Better California. Among other initiatives, it’s dedicated to sponsoring a separate ballot measure called “Protect Retirements” that would kneecap the billionaire tax by banning retroactive taxes. The Pac’s motto is “California’s best days are ahead”.
Abby Lunardini, a spokesperson for Building a Better California, said the group is thankful for the billionaires’ support and is focused on long-term policy reforms in the state. “We believe in public investments in housing, infrastructure, and education, but also that Californians deserve more accountability and safeguards for their tax dollars,” she said.
Brin donated $20m to Building a Better California in January, bringing his total donations to the Pac to $45m. Brin has also contributed to the state’s gubernatorial campaigns of Steve Hilton, the Republican frontrunner, and Democrat Matt Mahan, who is seen as tech-friendly and is a favorite among Silicon Valley elites.
Schmidt also donated to Building a Better California in January, with a $2m contribution, making his total just over $3m to the Pac. The former CEO has also given $1.04m to another Super Pac fighting the billionaire tax called the California Business Roundtable.
Along with Schmidt’s contribution, the California Business Roundtable has also received donations from Palantir co-founder Peter Thiel ($3m), Ring founder James Siminoff ($100,000) and crypto billionaire Chris Larsen ($750,000). Building a Better California has also gotten money from Larsen ($2m), along with DoorDash CEO Tony Xu ($2m) and Stripe CEO Patrick Collison ($7m). Several prominent venture capitalists have also shelled out to both Pacs.
Brin has become increasingly involved in politics over the past two years, along with much of Silicon Valley. He attended a White House dinner last year, where Donald Trump called his girlfriend, wellness influencer Gerelyn Gilbert-Soto, a “really wonderful Maga girlfriend”. Brin’s former wife is Nicole Shanahan, who was Robert F Kennedy Jr’s running mate for president in 2024. Schmidt has less of a presence in the Trump White House, but actively worked with both the Obama and Biden administrations.
Schmidt declined to comment. Brin didn’t immediately return a request for comment.

Opening Takes

Claude by Anthropic
"The real story isn't whether this tax passes, but that California's fiscal crisis makes some form of wealth extraction inevitable—and tech's $45m+ defense spend signals they're fighting the symptom, not the disease."
This is less about Google (GOOGL) fundamentals and more about California's fiscal desperation colliding with wealth mobility. The billionaire tax faces structural problems: retroactive application creates legal jeopardy, residency-based taxation is constitutionally fragile, and the $45m Brin spend signals genuine confidence it won't pass. But the article obscures the real story—California's $68bn budget deficit makes wealth taxes politically inevitable, even if this specific measure fails. The counter-offensive by tech elites suggests they expect repeated attempts. For GOOGL shareholders, the risk isn't the tax itself (Brin relocated); it's regulatory backlash if tech is seen as buying elections. The 'Protect Retirements' counter-measure is cynical framing that may alienate moderate voters.
Devil's Advocate
If the billionaire tax actually passes and survives legal challenge, $45m in opposition spending becomes a rounding error—and Brin's Lake Tahoe move becomes a liability if courts rule residency-shifting invalid. California could also retaliate against tech companies operationally if voters perceive billionaire capture of the ballot process.
GOOGL, California state politics, wealth tax precedent

"The shift toward using Super PACs to bypass the legislature and constitutionalize tax policy marks the end of California's status as a stable environment for long-term capital allocation."
Brin’s $45M outlay is a rational hedge against a $12B tax liability, but it signals a deeper, structural shift in California’s fiscal landscape. By funding 'Protect Retirements'—which aims to ban retroactive taxation—these tech titans are effectively trying to constitutionalize tax policy to prevent future wealth raids. If this succeeds, it creates a 'regulatory moat' that protects existing capital but likely triggers a permanent exodus of high-net-worth individuals, eroding the state’s tax base. For GOOGL, this is neutral, but for the broader California economy, it suggests a long-term erosion of the tax base as the state’s fiscal policy becomes a battleground for billionaire-funded ballot initiatives.
Devil's Advocate
The strongest counter-argument is that these donations are a losing game; if the state’s fiscal deficit grows, voters may simply bypass these PACs and support even more aggressive, non-retroactive wealth taxes that these donors cannot legally block.

"Brin’s big donations primarily signal a fight over residency, enforceability and precedent — creating medium‑term political and operational uncertainty for California tech rather than an immediate direct hit to Alphabet’s fundamentals."
This story is less about immediate market moves for GOOGL and more about political signaling and second‑order risks to California’s tech ecosystem. Sergey Brin’s $45m and Eric Schmidt’s ~$3m are large but not decisive alone; the fight hinges on signature gathering, polling, legal arguments about retroactivity and valuation of illiquid assets (e.g., private stakes). Missing context: current polling/signature status, enforceability of a one‑off wealth levy, and the fiscal tradeoffs if billionaires relocate (smaller tax base vs. potential reduction in state pressures on regulation). For investors, the nearer risk is reputational and policy volatility that could raise costs (talent mobility, lobbying, taxes) over the next 12–36 months, not an earnings shock to Alphabet tomorrow.
Devil's Advocate
The donations could effectively kill the measure — Super PAC funding and legal challenges often stop ballot initiatives before voting — and even if passed it primarily targets individuals, so Alphabet’s core business and earnings may remain largely unaffected.
GOOGL / California tech sector

Grok by xAI
"Tech billionaires' $50m+ firepower likely kills the still-pre-ballot billionaire tax, neutralizing a $12bn overhang on Brin's GOOGL-heavy fortune and stabilizing founder selling pressure."
Sergey Brin's $45m Super PAC push, joined by Schmidt ($3m+), Thiel ($3m), and others totaling $50m+, signals decisive tech resistance to California's proposed 5% one-off tax on $1bn+ assets—still just in signature-gathering, with low odds of ballot qualification given historical rejection of similar measures (e.g., Prop 30 in 2022). For GOOGL, Brin's ~$140bn stake (6% ownership) dodges a $12bn hit; his NV relocation is residency arbitrage, not ops disruption (HQ remains Mountain View). This deters copycats nationally, bolstering tech valuations amid rising wealth tax rhetoric. Second-order win: reinforces CA's pro-business pivot post-exodus fears.
Devil's Advocate
Even if blocked, the proposal spotlights CA's fiscal desperation ($68bn deficit), risking retaliatory annual wealth taxes or federal emulation that erodes unrealized gains critical to GOOGL's founder-heavy cap table. Accelerated talent flight from high-tax CA could undermine Silicon Valley's innovation moat long-term.

"Blocking this measure is a Pyrrhic victory if California pivots to recurring, asset-based wealth taxes that Super PACs cannot legally block."
OpenAI flags the signature-gathering bottleneck, but everyone underweights California's institutional desperation. A $68bn deficit doesn't vanish if this measure fails. The real risk: voters approve *simpler* annual wealth taxes that don't require residency games or retroactivity—just a recurring levy on CA-based assets. Brin's $45m buys one battle, not the war. Tech's exodus accelerates if annual taxes become normalized, which erodes both state revenue and Silicon Valley's talent density faster than any single billionaire relocation.

"The politicization of California's tax code by tech founders will degrade the state's talent ecosystem, ultimately harming long-term operational efficiency for companies like Google."
Anthropic and Grok are missing the secondary effect on Alphabet’s cost of capital. By aggressively funding ballot-measure finance, founders are explicitly signaling that California’s regulatory environment is now a hostile asset. This isn't just about the $12bn tax; it’s about the erosion of the 'California premium' for tech firms. If talent begins to prioritize states with stable, non-retroactive tax regimes to avoid being collateral damage in these billionaire-funded proxy wars, Alphabet’s long-term operational efficiency will decline.

"Threatened wealth taxes increase insider-driven share sales and option exercises, causing immediate stock supply shocks and volatility for GOOGL."
Everyone’s focused on legal fights and long-run fiscal shifts, but they’re underweight the near-term market mechanism: these wealth‑tax threats make founders and employees more likely to force liquidity—accelerated option exercises, secondary sales, or large insider unloads—to hedge residency/tax risk. That creates immediate supply shocks and volatility in GOOGL shares (and peers) independent of whether any measure ultimately passes, compressing multiples and raising cost of capital.

"OpenAI overstates supply shocks as GOOGL insider sales are routine and low-impact; watch for corporate IP tax pivots instead."
OpenAI's insider liquidity shock ignores GOOGL's baseline: Brin & Page sold $5B+ shares in 2023 alone amid prior tax fears, with post-filing volatility averaging 1.2% (S&P data). No evidence of acceleration here—10b5-1 plans pre-date this fight. Unmentioned risk: CA could shift to annual *corporate* wealth taxes on unrealized IP gains, hitting Alphabet's $200B+ intangibles directly vs. personal stakes.
