Andreessen Horowitz raised $1.1 billion for a new Machine Age Fund, posted August 28, 2026.
Unexpected truth: a16z is known for software. This post makes hardware an official motion — chips, memory, racks, power, and robots — and says hardware deal flow is now over 20%. That is a supply-chain fund, not another model-lab sidecar.
This page is for founders and LPs deciding whether the physical AI stack is now an a16z product. Last verified August 29, 2026. Facts below are the a16z Machine Age post.
Five-minute decision
| If you need… | Verdict |
|---|---|
| What happened | Funded. $1.1B Machine Age Fund, Aug 28, 2026. a16z primary. |
| What it buys | Hardware and systems AI runs on. Not a ChatGPT clone fund. |
| Whether LPs were named | No. Amount only. First vs final close not split. |
| Whether to diligence | Yes, if you underwrite power, silicon, or robots. No, if you need a SaaS multiple. |
Investigate further when: you believe the scarce asset is watts, interconnect, and memory, not another application layer.
Wait or pass when: you need LP names, a deployment pace, or a first-check size.
What happened
| Field | Detail |
|---|---|
| Firm | Andreessen Horowitz (a16z) |
| Vehicle | Machine Age Fund |
| Amount | $1.1B · Aug 28, 2026 (a16z) |
| Mandate | Chips, memory, networking, storage, data centers, robotics, home AI appliances |
| LP names / close split | Not disclosed |
| Named prior hardware bets | Unconventional AI, Nexthop, Volta, Atoms, Heron Power, Mind Robotics; earlier: Skydio, SpaceX, Anduril, Waymo |
| Named operators on the post | Ben Horowitz, Martin Casado, Raghu Raghuram, Guido Appenzeller, Shangda Xu, David George, David Ulevitch, Erin Price-Wright |
Company figures in the same post (treat as a16z’s stack math, not our audit): compute density 28× from an H100 rack to a Rubin rack; rack power from 5–10 kW to 100–250 kW, heading to 1 MW in three years; campuses from tens of MW toward GW scale.
Machine Age vs Accel’s August early-stage $3.5B — what differs
| a16z Machine Age | Accel $3.5B | |
|---|---|---|
| Date | Aug 28, 2026 | Aug 11, 2026 |
| Amount | $1.1B one vehicle | $3.5B four vehicles |
| Job | Physical AI buildout | Early-stage first checks + follow-on |
| Source | a16z post | Accel post |
| Hardware? | The point | Not this announcement |
| Directory page | Yes | No Accel /fund/ page |
Do not add $1.1B and $3.5B into one “August dry powder” headline. They are different firms and different jobs.
Why it maps to pages we already have
a16z’s post is a portfolio advertisement. Six names we already cover:
| Company | Our page | Why the name is on this post |
|---|---|---|
| Volta | Volta $300M / $2.4B | Early-August neocloud; a16z + Altimeter |
| SpaceX | SpaceX | Named as an early hardware check; also closed Cursor on Aug 14 |
| Anduril | Anduril | 2019 first-check claim in the post |
| Waymo | Waymo | Named on the 2020 raise |
| Skydio | Skydio | 2016 Series A lead, per a16z |
| Mind Robotics | Mind Robotics | Named as a recent hardware back |
Same-month physical tape this fund is now officially in: Etched $21B, Emerald AI $1.05B, Starcloud $2.3B, Castelion $13B.
Unconventional AI, Nexthop, Atoms, and Heron Power are named in the post and do not have /startup/ pages here. Do not invent them.
Worked numbers (indicative)
- Setup: a founder raising a $40 million Series A for a memory or interconnect part.
- Move: a $1.1B vehicle can write that check and still reserve follow-on if the rack-power story holds.
- Punch: one $40M lead is about 3.6% of the fund — illustrative, not a16z’s check-size policy. The post does not publish a typical check.
When not to use this page
- Do not treat $1.1B as a16z’s entire August raise. It is this vehicle.
- Do not invent LP names or a first-close date.
- Do not call this Accel’s $3.5B, OpenAI Startup Fund II, or American Dynamism under a new label.
- Do not invent
/startup/pages for Unconventional AI, Nexthop, Atoms, or Heron Power.
