[21] Tan has been actively involved and influential in San Francisco politics, both by directing attention to various topics via his social media presence and through donations.

Examples of causes espoused by Tan include increased funding for police, and opposition to regulation of self-driving cars, changes to education, decelerationism, Apple's monopoly on apps, and censorship by YouTube.

[22][28] Tan called Y Combinator a "prototype model" of Balaji Srinivasan's Network State, which Gil Duran described as an anti-democratic, pro-plutocratic movement in an April 2024 piece for The New Republic.
