a16z emerges as big spender, directing cash into Anduril, US mid-terms

Rather than wait for the regulatory environment to shape itself, Andreessen Horowitz (a16z) has gotten directly involved in funding AI technology, lobbying for the rules, and helping choose the people who write them. 

On the same day that reports surfaced that a16z had become the largest donor in the 2026 U.S. midterm election cycle, AI defense technology Anduril also revealed that it received billions in investments from the firm. 

$115 million in political donations from a16z

Andreessen Horowitz’s checkbook (a16z) has been busy as one of the largest political donors of the 2026 midterms, also confirmed a massive investment into defense tech company Anduril. The company’s autonomous weapons factory is now operational in Ohio.

Cryptopolitan reported that the firm’s crypto division announced its fifth fund earlier in May, raising $2.2 billion for Web3 startups. Through these five funds, a16z’s total dedicated crypto capital is about $10 billion. 

According to a New York Times analysis, a16z and its co-founders Marc Andreessen and Ben Horowitz have donated more than $115 million in disclosed federal contributions to midterm election efforts so far. 

This puts them ahead of Democratic megadonor George Soros, who has donated $102.9 million, and Tesla (NASDAQ: TSLA) CEO Elon Musk, who has put in about $85 million. The firm gave more than $23 million to the political action committee Fairshake and its affiliates to support crypto-friendly candidates during the 2026 midterm elections. 

On the investment side, Anduril announced a $5 billion Series H funding round led by Thrive Capital and a16z, bringing its valuation to $61 billion. 

Cryptopolitan previously reported that Andreessen Horowitz raised over $15 billion across multiple funds in its 2025 fundraising rounds and currently has over $90 billion in assets under management. The company raised $6.75 billion for growth, $1.7 billion each for apps and infrastructure, and $1.176 billion for American Dynamism, its national security and government tech vertical. 

Why is a16z spending big on elections?

Marc Andreessen has stated he is a “single-issue voter,” meaning he casts his ballot purely on what is good for tech startups. After feeling hostility from the Biden administration on crypto and AI policy, a16z backed the Trump campaign and deepened its presence in Washington. 

The firm donated $47.5 million to crypto super PAC Fairshake and $50 million to Leading the Future, a pro-AI super PAC. Andreessen personally spends significant time advising the Trump administration on tech policy.

On defense, Anduril’s investor letter argues that the U.S. defense base is built around expensive, long-cycle platforms like $3 billion warships rather than cheap, mass-produced autonomous systems. 

The $5 billion raise is aimed at scaling Arsenal-1 to fix that. By the end of 2026, the Ohio factory will be producing Fury combat drones, Roadrunner interceptors, Barracuda cruise missiles, and a classified platform. At full capacity, the Fury production line alone can produce 150 aircraft per year, running three shifts daily. 

The Trump admin has been good for U.S. tech firms. Anthropic is in early talks with investors to raise at least $30 billion in fresh investments at a valuation of more than $900 billion. The round is expected to close by the end of this month, despite the fact that the deal is not finalized and no term sheet has been signed. 

Anthropic previously closed a $30 billion Series G in February 2026, led by GIC and Coatue, valuing the company at $380 billion. At the time of Series G, Anthropic’s run-rate revenue had reached $14 billion due to demand from enterprises and developers. 

Despite April 2026 being the lowest monthly crypto raise in a year at $662.4 million, a16z has pressed ahead with its $2.2 billion Crypto Fund 5. The figure is notably smaller than the $4.5 billion raised in 2022. Chris Dixon, a16z crypto founder, has said the focus is on “practical applications” like stablecoins, which continue to grow even in downturns.
