San Jose Mayor Matt Mahan’s bid for the California governorship has received a significant boost with $4.8 million in television advertising support from an independent expenditure committee. The ads, which began airing Thursday, February 26, 2026, highlight Mahan’s personal story and record as mayor, aiming to establish him as a relatable and effective leader in a crowded field vying to replace Governor Gavin Newsom.
The financial backing underscores the growing interest in Mahan’s candidacy, particularly among Silicon Valley’s influential tech leaders. Even as Governor Newsom is termed out of office after serving two terms, the race to succeed him is already shaping up to be highly competitive, with several prominent figures vying for the state’s highest office. Mahan’s ability to attract substantial donations, especially from the tech sector, positions him as a serious contender, despite lacking the widespread name recognition of some of his rivals.
Independent Expenditure Fuels Mahan’s Campaign
The advertising campaign is being funded by California Back to Basics Supporting Matt Mahan for Governor 2026, an independent expenditure committee. Which means the committee can raise and spend money to advocate for Mahan’s election without coordinating directly with his campaign. Independent expenditure committees are a common feature of modern American political campaigns, allowing outside groups to amplify a candidate’s message and reach voters. According to campaign finance laws, these committees must disclose their donors, providing transparency into the sources of funding influencing the election.
The two 30-second advertisements focus on Mahan’s biography, portraying him as a working-class Californian who understands the challenges faced by everyday families. The ads emphasize his upbringing, highlighting his experiences working on a grounds crew and as a middle school teacher. A narrator in one of the ads states that Mahan’s parents “taught him the difference between nice to have and need to have,” framing his approach to governance as focused on essential services and practical solutions. The ads also tout his accomplishments as mayor of San Jose, claiming he has made the city “the safest substantial city in America,” reduced homelessness, and overseen the construction of thousands of homes.
Silicon Valley Support and Key Donors
The committee’s financial support comes primarily from prominent figures in the Silicon Valley tech industry. Major donors include billionaire venture capitalist Michael Moritz, founder of luxury sleepwear company Ashley Merrill, and Silicon Valley entrepreneur Michael Seibel. The Los Angeles Times reported on the $4.8 million investment in television ads.
The involvement of billionaire Los Angeles developer Rick Caruso is also noteworthy. Caruso, who previously considered running for governor or mayor of Los Angeles but ultimately decided against it, is reportedly involved in the effort supporting Mahan, according to a strategist with the committee who requested anonymity. Caruso’s experience in real estate development and his connections within the California business community could prove valuable to Mahan’s campaign. Caruso’s previous political ambitions demonstrate a willingness to engage in high-profile campaigns and a desire to influence policy in California.
Mahan’s Fundraising and the Gubernatorial Race
Mahan officially launched his gubernatorial campaign four weeks ago, on January 29, 2026, as reported by the Los Angeles Times. Since entering the race, he has reportedly raised nearly $9.2 million in large donations, a significant sum that demonstrates his fundraising prowess and appeal to wealthy donors. This fundraising success is particularly notable given his relative lack of name recognition compared to other candidates in the field.
The 2026 California gubernatorial race is shaping up to be a complex and competitive contest. Governor Newsom’s departure creates an open seat, attracting a diverse range of candidates. The Los Angeles Times previously outlined the potential candidates for the 2026 election, including State Senator Toni Atkins, Lieutenant Governor Eleni Kounalakis, and former Los Angeles Mayor Antonio Villaraigosa. Mahan’s campaign will need to effectively leverage his fundraising advantage and the support of Silicon Valley donors to gain traction and compete with more established candidates.
The Role of Independent Expenditure Committees
Independent expenditure committees play a crucial role in modern political campaigns, particularly in states with high media costs like California. These committees allow individuals and organizations to contribute unlimited amounts of money to support or oppose a candidate, as long as they do not coordinate directly with the campaign. This separation is intended to prevent quid pro quo corruption and ensure that candidates are not beholden to specific donors. Although, the rise of independent expenditure committees has also raised concerns about the influence of money in politics and the potential for undisclosed interests to shape election outcomes.
The legal framework governing independent expenditure committees is complex and has been the subject of numerous court cases. The landmark Citizens United v. Federal Election Commission (2010) Supreme Court decision significantly expanded the ability of corporations and unions to spend money on political advertising, leading to the proliferation of these committees. Campaign finance regulations require independent expenditure committees to disclose their donors, but the disclosure requirements are not always comprehensive, and some donors may choose to remain anonymous through the use of shell corporations or other legal mechanisms.
San Jose’s Record Under Mayor Mahan
The advertisements supporting Mahan highlight his accomplishments as mayor of San Jose. Claims of making San Jose “the safest big city in America” and a “sharp drop in street homelessness” require further scrutiny. While San Jose has seen some positive trends in these areas, it is important to consider the broader context and compare its performance to other major cities. Data on crime rates and homelessness in San Jose can be found on the city’s official website and through reports from organizations like the U.S. Department of Housing and Urban Development (HUD).
Mahan’s focus on building affordable housing is also a key theme of his campaign. San Jose, like many cities in California, faces a severe housing shortage, driving up prices and making it difficult for residents to find affordable places to live. The city has implemented various policies to encourage housing development, including streamlining the permitting process and offering incentives to developers. However, the effectiveness of these policies remains a subject of debate, and the housing crisis continues to be a major challenge for San Jose.
The committee has not yet filed any fundraising reports with the California Secretary of State’s office, making a complete assessment of its financial backing difficult at this time. However, the disclosed donors – Moritz, Merrill, and Seibel – represent a significant concentration of wealth and influence within the Silicon Valley tech community. Their support suggests that Mahan’s campaign resonates with those who believe in a more business-friendly approach to governance and a focus on innovation and economic growth.
