Airbnb co-founder Joe Gebbia has contributed $8 million to the campaign supporting Proposition 39, a California ballot measure that would require voters to present government-issued identification, according to campaign information reported Oct. 7, 2026. The donation to Californians for Voter ID is Gebbia’s largest contribution to a California political campaign. The committee is chaired by Julie Luckey, whose son is tech entrepreneur and Republican megadonor Palmer Luckey. It has also received donations in the seven figures from conservative donors, including billionaire Richard Uihlein. Gebbia, a former Democrat who has said he voted for Donald Trump in 2024 and that Democrats have “lost their way,” has taken on a role in the Trump administration. After working on the Department of Government Efficiency project, he was named the first U.S. chief design officer. The $8 million contribution gives the voter ID campaign a substantial infusion of money ahead of the November vote. The available details did not specify how the measure would handle voters who lack government-issued identification.
