Bank the AIs

Brian Armstrong is the co-founder and CEO of Coinbase, the largest US crypto exchange, which he started in 2012 after working as a software engineer at Airbnb. He took Coinbase public in 2021 and has since pushed it toward what he calls an "everything exchange" for stocks, derivatives, prediction markets and crypto. He also co-founded NewLimit, a biotech company working on epigenetic reprogramming to restore youthful function to aging cells. Armstrong backs hard-tech and frontier science companies as an investor, and he has been one of the more vocal CEOs on pushing AI adoption inside his own company. These signals are from Brian Armstrong's interview with Elad Gil on No Priors.

1. Agent-Sized Payments. Card rails break on the transactions AI agents make. A debit or credit card charge carries a minimum fee of roughly 30 cents plus a percentage, and about 76% of the agentic commerce transactions Coinbase sees are under 30 cents. Armstrong's line: "it doesn't make sense to pay 30 cents to send a 1 cent payment." Most of these micro-payments are agents buying information: paywalled research for venture firms, scraped data for recruiters, or calls to other specialist agents.
2. Accounts for Agents. Coinbase wants every AI agent to hold its own money. "We don't want the AIs to be unbanked. We want to bank the AIs," Armstrong said. With one pasted prompt, an agent gets a self-custodial wallet on crypto rails, with no KYC step, since agents have no government ID and can't walk into a bank branch. Coinbase will also offer segregated agent accounts linked to a human's identity, so a person can hand an agent a capped budget for trading and payments.
3. Unblocking Stuck Agents. Today's agents stall at every paywall, AWS signup or hotel checkout and ask a human for a credit card. Armstrong expects agents to get spend accounts the way an assistant or employee does, likely with a stablecoin-backed card for backward compatibility. Much of the volume already runs over x402, a payment protocol Coinbase incubated and gave to the Linux Foundation, with Google, Cloudflare and AWS now involved. (The transcript renders it "X42.")
4. Specialist Agent Markets. Armstrong expects a marketplace of narrow agents selling services to other agents. Inside Coinbase, a small open-weight model trained on 100,000 internal compliance cases outperforms frontier models on that review queue. He pictures agents trained only on pizza ordering or on large amounts of proprietary Figma data. Because there will soon be more agents than humans, he argues the agentic economy will eventually be bigger than the human one.
5. The Company Brain. Coinbase is building toward "recursive self-improvement" inside its own engineering org. Each team, service and repository has a "brain" of markdown files holding every incident, financial control, A/B test and accepted or rejected pull request. When a human corrects an agent's change, the rule is that the fix goes back into the brain, so the mistake gets corrected for every future change too. Armstrong says the rate of one-shot PRs that get accepted climbs over time as a result.
6. The CEO Ships Again. AI tooling has put Armstrong back into the codebase. Before the podcast he asked an expensive model to plan a feature in 3 phases of 10 pieces each, then had it spin up 10 parallel agents on cheaper models to build phase one. All 10 pieces were ready for review 2 minutes before he went on air. Instead of pinging the team in Slack with ideas all day, he now sends them finished PRs, which he calls "very addictive."
7. Tasks, Not Headcount. Armstrong rejects the idea that AI will shrink Coinbase to 10 people. In his view AI eliminates tasks and leaves the people, who get much more done at a faster pace. Tiny 2- or 5-person companies will also do more than anyone thought possible. The host's corollary: if revenue grows faster than the team, margins should rise.
8. Beyond Bitcoin. Coinbase's stock still trades in step with Bitcoin, yet 88% of its revenue now comes from non-Bitcoin trading, according to its recent earnings deck. Its new tokenized stocks are, per Armstrong, the first truly tokenized product: an actual security backed 1:1 by shares in custody, with no synthetic or derivative wrapper. It's available only outside the US for now. Roughly 4 billion people lack access to a brokerage or US investment account, and Armstrong expects them to want Nvidia or Apple shares much as they wanted Tether's dollars.
9. Tokenize Everything. Stablecoins were the first tokenized asset, and Armstrong expects private credit, treasuries and bank deposits to follow stocks onto chain. Once assets are tokens, gifting a share to a nephew means sending it to his wallet, with no stock transfer paperwork. Stablecoin payments keep growing even when Bitcoin falls, and they move money anywhere in under a second for under a cent. Crypto still powers only about half of 1% of global GDP, and Coinbase's target is a billion regular users, up from what Armstrong estimates as 50 to 100 million monthly users today.
10. Opinion Markets. Prediction markets inside the Coinbase app hit a $100 million revenue run rate within months of launch and are growing over 100% quarter over quarter, by Armstrong's rough recollection. He sees sports as only the start. Governments could float markets on a policy's effect on unemployment in 1, 2 and 3 years, and people could trade on questions with no resolution date, such as whether God exists, the way stock investors bet on direction with no final payout.
11. Longevity's Bitcoin Moment. NewLimit began with dinners where Armstrong asked top scientists which high-potential bio idea was underfunded. Epigenetic reprogramming kept coming up, and he couldn't stop thinking about it for 3 months, the way he felt about Bitcoin in 2010. The South San Francisco lab now has 50 to 60 people and an AI model that picks which transcription factor combinations to screen next. It has reprogrammed at least one human cell type in humanized mice, is testing in non-human primates, and plans a phase 1 trial in alcoholic liver disease next year, a market Armstrong puts at about $20 billion on its own.
12. Sandboxes for Progress. Armstrong wants special economic zones in the US: 10 to 100 square miles of federal land where builders could put up data centers and nuclear plants or run drone delivery without EPA or FAA approval. Overregulation slows progress, and "there is no sandbox to go try this innovation," he said. Ideas that work in the zone would then go through the normal process elsewhere. Coinbase invested in Próspera in Honduras to learn how these zones work, and Armstrong points to Shenzhen, Singapore and Dubai as zones that drove growth.
