Saikat Chakrabarti: A Closer Look at His Campaign and Policies

Saikat Chakrabarti is a unique candidate as the clear outsider to Bay Area politics. He worked as a founding engineer for Stripe, a financial technology company that provides payment processing software for businesses. Chakrabarti’s first foray into politics began in 2015 as the Director of Organizing Technology for Bernie Sanders’ presidential campaign. He then co-founded the Justice Democrats and Brand New Congress, organizations created to replace incumbent Democrat and Republican lawmakers with progressive candidates. In 2019 Chakrabarti became Alexandria Ocasio-Cortez’s chief of staff in Washington, D.C. He also helped launch the Green New Deal.

Most recently he led New Consensus, a think tank focused on climate and economic policy. The organization most recently published Mission for America, a 23-chapter economic-policy blueprint that serves as the intellectual backbone of his campaign. To better understand his platform, The Fogline attended two candidate events: the KQED debate at the Sydney Goldstein Theater, and the SF Independent Media Coalition forum at the United Irish Cultural Center on April 15. At the Irish Cultural Center, Chakrabarti described Mission for America in his own words:

Chakrabarti is a centimillionaire from his work at Stripe. He holds at least $50 million in Stripe equity per financial reports. His vast holdings in tech equity have allowed him to personally finance his campaign. As of the April 15, 2026 FEC filing, Chakrabarti's campaign has taken in approximately $5.18 million. Of that total, about $4.82 million came from personal loans Chakrabarti made to his own campaign.

Chakrabarti made a pledge on social media that he will not accept corporate PAC donations. He goes further to advocate for a total ban on corporate PAC money in the primary and general elections. Money from small donors totals roughly $360,000 from about 13,000 individuals.

Some critics have pointed out that Chakrabarti effectively does have corporate funding in the form of his personal fortune from Stripe. Others have asked why he hasn’t divested from that fortune or donated the proceeds to the causes he champions. Chakrabarti has been gradually selling Stripe equity, but tens of millions in Stripe holdings remain. This means he continues to benefit financially from an industry his platform takes aim at. A fair question is whether his slow selling reflects strategic timing. Stripe is one of the most anticipated IPOs in tech, and a public listing would likely push the stock's value well above its private market price. Chakrabarti could be waiting to realize the largest portion of his "startup lottery" winnings at their peak.

While being self-funded helps Chakrabarti avoid being beholden to outside interests, for critics it presents a big question mark regarding his motives and claims of “buying the seat.” While Scott Wiener spent years building a base in San Francisco, Chakrabarti can simply use his vast wealth to boost his signal. For critics, it is a sticking point when a candidate who decries the effects of wealth inequality can simply use his powerful wealth to avoid the grassroots organizing that a typical campaign requires. The anti-Chakrabarti PAC Abundant Future has spent over $200,000 highlighting this very criticism.

The 13,000 donor figure has also come under scrutiny. The day before the Q1 FEC filing deadline, Chakrabarti's campaign sent an email blast asking supporters for $1 donations specifically to inflate the visible donor count. The email has been circulating on social media:

A related critique is his outsider status, both to elected office and to San Francisco itself. Chakrabarti has never held elected office or passed public legislation, and he is often tagged as a "carpetbagger" by critics given his relatively recent continuous residency in the city. He also lacks any local union or elected-official endorsements, a gap his campaign frames positively as proof of his independence from the San Francisco political machine. In his closing statement at the Irish Cultural Center forum, he reframed the experience question directly:

Still, Congress is a tough place even for experienced legislators, and his lack of both electoral experience and local roots remains a challenge for voters evaluating the candidates on their records.

Chakrabarti is a vocal supporter of the Ultra-Millionaire Tax Act proposed by Elizabeth Warren. The act would impose a 2% tax on the net worth of households above $50 million, and a 3% tax on households above $1 billion. He also proposes to tax Margin Loans with which the ultra-wealthy avoid paying capital gains taxes by never selling their stock. Instead, they take out low-interest loans using their stock as collateral.

He wants to raise taxes for the highest earners from 37% to 90% and raise the corporate tax rate back to over 50%.

Chakrabarti is in support of San Francisco's Proposition D (“Overpaid CEO” Tax) on this June's ballot, which would increase taxation on companies where the CEO earns more than 100 times the median salary of the employees. He also supports the California Billionaire Tax Act, a proposed November 2026 ballot measure that would impose a one-time 5 percent tax on the net worth of California residents worth more than $1 billion. The measure would apply to roughly 200 people statewide, with revenue directed toward health care, education, and food assistance.

Chakrabarti's taxation policy is one that many countries have already tried and discarded. As The Economist reported in October 2025, twelve wealthy nations maintained annual wealth taxes in 1990. Today, only three still do: Norway, Spain, and Switzerland. Nations like France, Sweden, and Germany all repealed theirs after discovering problems such as high administrative costs, disappointing tax revenue, and the exodus of wealthy residents and their capital. Even Norway saw a spike in "billionaire flight" to Switzerland after increasing its wealth tax rate to 1.1% in 2022. The resulting loss in broader economic activity likely outweighed the gains from the tax itself.

Beyond the global track record, the plan faces another hurdle in the form of valuation. For a candidate whose fortune is tied to a private company like Stripe, determining a fair tax price is nearly impossible without an annual audit of the company’s entire books. Unlike public stocks which have a daily ticker, private equity value is often theoretical until it’s sold. By proposing to tax these "paper gains" every year, Chakrabarti is betting that the U.S. can enforce this without economic flight. His campaign hasn’t addressed why a wealth tax will succeed here when it resulted in a net loss for almost everyone else that tried it.

The flight risk is not hypothetical for the California Billionaire Tax Act specifically. It has already begun before the measure has even qualified for the ballot. Google co-founders Larry Page and Sergey Brin have relocated to Florida. Uber co-founder Travis Kalanick moved to Texas in December 2025. Peter Thiel (an early Stripe investor) has been exploring out-of-state alternatives. Per Fortune, at least six of California's 200+ billionaires departed the state before the January 1, 2026 residency cutoff that would determine liability under the measure. Some might say "good, let them leave,” but that carries a cost. When they leave, the tax revenue leaves with them, and so does the funding for the health care, education, and food programs it was supposed to pay for.

Beyond "tax the rich," Chakrabarti's platform is built on a framework for public ownership that he has articulated consistently across both candidate events we attended. Where a market is a natural monopoly, he argues, it should be publicly owned. Where markets function but fail to serve everyone, the government should provide a public option. He applies this framework across his platform, including healthcare, child care, education, and federally-manufactured generic drugs. It shows up most concretely in three domains we highlight here: housing, public power, and AI infrastructure.

Where Scott Wiener is focusing on deregulation of the private housing market and incremental progress, Chakrabarti calls for massive federal intervention to build housing directly. He views housing as a human right that the private market has failed to provide. His proposed Federal Housing Finance Agency would have the power to build housing that the private market won’t.

His platform calls for massive federal investment into publicly-owned, mixed-income social housing that is insulated from market speculation. He has stated he wants to repeal the Faircloth Amendment, the federal law that prohibits the U.S. from increasing its public housing stock.

Chakrabarti’s website policy section states he will propose housing legislation that will provide tens of thousands of homes in San Francisco. His plan to prevent housing displacement for those already in the community includes seeking federal financing to expand rental assistance programs for low-income renters. He proposes supporting community land trusts to safeguard current low-income housing. He also supports making rent payments tax-deductible, and states he will target corporate landlords to address predatory speculation and price-fixing.

Chakrabarti's most aggressive local proposal is to municipalize PG&E. He argues that San Francisco has a century-old federal obligation under the 1913 Raker Act to distribute power directly to its residents, a promise the city has effectively broken by allowing PG&E to charge fees for the use of its wires. San Francisco is currently in a formal eminent-domain proceeding at the California Public Utilities Commission, launched in 2021 and expected to produce a valuation ruling in early 2027. Scott Wiener has introduced state legislation (SB 875) to make that process easier. Chakrabarti's framing is federal rather than state, so he just has a different route to the same goal.

Proponents of municipalization often point to Seattle City Light, where customers pay roughly $0.16 per kWh thanks to a publicly-owned grid. PG&E rates in San Francisco have run about three times that level.

Chakrabarti has proposed a specific response to the AI investment bubble he expects to burst. Instead of bailing out failing AI companies, the federal government should convert their data centers into public utilities. As he put it at the Irish Cultural Center forum:

He pairs this with regulations that would apply immediately. Data centers must be powered entirely by clean energy and must overbuild their generation so that consumer electricity bills go down when a data center enters a community. Chakrabarti has cited the Tennessee Valley Authority, which in the 1930s acquired a failing private utility and ran it as a publicly-owned provider, as the historical model for how this kind of transition could work.

The public ownership framework also has its skeptics. "Public" is not the same as "well-run." Los Angeles' municipal utility LAWDP, the country's largest and the closest comparable to a hypothetical public PG&E, has been plagued by corruption scandals, executive-pay controversies, and rate spikes. A publicly-owned utility is accountable to ratepayers in theory, but in practice that accountability runs through local politics, which has its own way of failing us.

The AI buyout proposal also raises questions. Who would operate the converted “public” data centers? Would it be the Department of Energy? A new federal agency? Also, AI workloads require hardware refreshes every 1-2 years, and federal procurement cycles are notoriously slow. Also, who are the supposed failed AI startups that run their own data centers? OpenAI and Anthropic, the companies most associated with the AI bubble, don't own their data centers. They rent capacity from Google, Amazon, and Microsoft, whose diversified businesses wouldn't fail in a bubble burst. The smaller AI labs most likely to actually fail don't own data centers either.

On housing, Chakrabarti's mixed-income social housing model is specifically designed to avoid the failure mode of public housing in New York, where the country's largest public housing system suffered decades of decay from concentrated poverty and chronic underfunding. But the sheer scale of federal coordination required to build tens of thousands of units in a high-cost city like San Francisco remains a challenge.

For the primary, State Senator Scott Wiener will rely on his legislative record. Supervisor Connie Chan will rely on her local ties. For many voters Chakrabarti represents the biggest gamble. The result is a campaign defined by a paradox. Is Chakrabarti’s personal wealth a contradiction or a liberation? Can the campaign call itself a people-powered movement if contributions by individual donors make up only 7% of the budget? Or is the campaign able to be more aligned with the people by not having to beg rich donors for money? Chakrabarti is asking San Francisco to believe he can use the tools of the master to dismantle the house, and that a centimillionaire can credibly run a campaign on ending the billionaire class.

Much of the conversation about Chakrabarti's candidacy stops at his wealth, his Stripe equity, or how he made his money. Less attention has gone to what he is actually proposing to do in office. Whether voters look past his origin story, and whether his platform resonates with them, is what San Francisco decides on June 2.
