Andreessen Horowitz, the venture capital giant known in Silicon Valley as a16z, has reportedly become the biggest known political donor bloc of the 2026 midterm elections, pouring more than $115 million into federal politics as the technology industry fights to shape the future of cryptocurrency and artificial intelligence regulation.
The figure, first reported by The New York Times, includes disclosed federal contributions by the firm and its co-founders, Marc Andreessen and Ben Horowitz. The total puts Andreessen Horowitz ahead of George Soros, Elon Musk, and Jeff Yass in known political giving this cycle. Soros had disclosed $102.9 million, Musk $85 million, and Yass $81.8 million.
