Funding · 1 September 2026
Andreessen Horowitz said on 31 August that additional capital brings its fifth Growth fund to $8.5 billion. The vehicle launched in January at $6.75 billion; the new close adds $1.75 billion. The announcement came days after a16z raised $1.1 billion for a separate Machine Age Fund aimed at AI hardware — chips, memory, networking, and storage.
General partner David George, who leads Growth, wrote that AI-era companies reach the growth stage faster and consume more capital at higher valuations. Over seven years the Growth practice has backed more than 100 companies. Named focus areas now include enterprise and consumer AI, American Dynamism and defense tech, robotics and autonomy, healthcare and programmable biology, and the AI compute stack.
The firm’s Growth page lists prior work with companies such as Anduril, Databricks, OpenAI, SpaceX, Stripe, and Waymo. In January a16z said it had raised more than $15 billion across new funds and managed about $90 billion.
For founders, the signal is that late-stage AI checks are still getting larger even as public markets debate circular financing among chipmakers, clouds, and model labs. For limited partners, it is a bet that the bottleneck has moved from model demos to deployment, hardware, and industrial customers.
Key takeaway a16z now has an $8.5 billion growth vehicle plus a $1.1 billion hardware fund pointed at the same stack: models, robots, defense, and the machines that run them.
