Cathie Wood says the next generation of smart investors should stop only “following the developers” and start “following the agents” — and the race to become the financial network AI agents actually use could decide which cryptocurrencies win.
By Carlos Martinez | October 5, 2026
For years, venture capitalists had a simple rule for spotting the next big thing in tech: follow the developers, because engineers gravitate toward tools that matter. Cathie Wood, CEO of ARK Invest, thinks there is a new sheriff in town. Speaking on a panel at Robinhood’s Summit in Houston, she said investors are “probably going to be talking more and more about ‘follow the agents'” — referring to AI agents, software that can carry out tasks on a person’s behalf rather than simply answering questions. Her comment, reported by CoinDesk, was brief. The implication for crypto investors is not.
When AI Stops Answering and Starts Spending
Here is the shift in plain English. Today’s AI chatbots tell you which hotel has the best reviews. An AI agent books the hotel, pays for it, and confirms the reservation while you sleep. The moment agents go from giving answers to spending real money, a new question appears: what payment system do they use? A person might authorize an agent to spend up to 500 USD booking a hotel without handing it the keys to an entire bank account — and should be able to cancel that authority and see a record of everything the agent did.
Joseph Chalom, co-CEO of SharpLink and former head of digital assets at BlackRock, raised the stakes in a three-part series on agentic finance. “A world full of intelligent agents means nothing if a handful of companies decide where your money can go,” he wrote. He also argued people should be able to move their agents between financial providers — carrying identity, financial information and permissions the same way you take a phone number from one carrier to another — rather than being locked into one company’s system.
Why Crypto Wants This Job
This is where blockchains enter the picture. Chalom said open networks such as Ethereum could serve as a common financial layer that different agents, apps and companies all share — a shared highway for money, instead of every AI company building its own private toll road with itself in the middle of every transaction. That openness argument is the crypto industry’s pitch to become the wallet of the machine economy.
BlackRock, the world’s largest asset manager, connected the same dots in a September paper. It argued that AI agents could create entirely new demand for payment systems built for machines: an agent might need to pay for an API call, buy data from another service, or rent computing power — all without waiting for a human to approve each transaction. Stablecoins are a natural fit because they move around the clock, and blockchain protocols let software send small payments directly to other software. Coinbase’s x402 protocol, for example, is designed exactly for machines paying machines for online services like data access.
- Cathie Wood — “follow the agents” as the new investing lens, speaking at Robinhood’s Summit in Houston
- Joseph Chalom — warned against a handful of companies controlling where agents can send money
- BlackRock — September paper sees agents paying for data, API calls and computing power with stablecoins
- Coinbase x402 — a live protocol letting machines pay machines for online services
- Brian Armstrong — said “Grok is the leading client for agentic traders on Coinbase currently”
The Competition Is Not Waiting
Crypto does not have this market to itself — not even close. Stripe, Visa, Google and OpenAI are all building ways for agents to make purchases, and BlackRock explicitly noted that traditional payment systems will remain important. The likely outcome is a split world: some agent payments running on old rails, some on new ones. That contest is precisely why Wood’s advice matters. If AI agents become major economic actors, watching where they transact becomes a new way to measure whether stablecoins and blockchains are gaining real-world use, or whether most machine spending quietly stays on Visa and Stripe.
There are early signs of agents showing up inside crypto itself. Coinbase CEO Brian Armstrong said on X that “Grok is the leading client for agentic traders on Coinbase currently,” though he did not provide figures or further details on the activity. Treat that as an anecdote, not a statistic — but it shows the direction: software wallets trading on exchanges without a human clicking buttons.
What This Means For Your Portfolio
For a regular investor, the actionable takeaway is a new measuring stick. Instead of asking “does this coin have a big community?”, ask “could an AI agent actually use this network to pay for something today?” Networks that answer yes — major smart-contract platforms, stablecoin issuers, payment-focused protocols — have a plausible claim on machine-driven demand that old finance cannot easily replicate. That does not mean buying tokens on the promise alone; agent activity on chain is still tiny compared with human trading. It means adding “agent readiness” to your checklist and watching on-chain payment volumes for evidence that machines, not just marketers, are using the network.
The Verdict: Watch the Wallets, Not the Whitepapers
Wood’s one-liner captures a real inflection point. The battle over agentic finance — open blockchains versus a handful of banks and tech platforms — will decide who earns the transaction fees of an AI-driven economy. For now, nobody has won. The investors who benefit will be the ones who follow the agents literally: tracking which payment networks machines actually choose when they spend. When that data starts showing up on chain, it will be the closest thing to a receipt for crypto’s next growth story.

every ai company building its own private toll road with itself in the middle of every transaction. chalom nailed it with that one
wood saying follow the agents at a robinhood summit of all places, ten years ago she was all in on devs. narrative speedrunning
she called the tesla move years before anyone cared, being narrative first is her whole brand. armstrong and wood on the same page is the actual signal here
Armstrong saying Grok is the leading agentic client on Coinbase with zero numbers attached. Anecdotes are not metrics.
fair point but x402 is literally live and doing machine to machine payments today. someone has to be first
live today and used by three demos. being first only matters if x402 survives contact with real compliance requirements
if grok volume were bad armstrong wouldnt bring it up unprompted. coinbase has zero reason to hype an integration nobody uses
zero numbers is the whole problem with agentic stats right now. every dashboard counts agent wallets differently so people just quote vibes at each other
the chalom line about porting your agent between providers like a phone number is the most underrated part of this. lock-in is the real fight, not the rails
armstrong casually dropping that grok is the top agentic client on coinbase with zero numbers attached… cool story bro, show the volume
even with zero numbers attached, armstrong naming a client he does not own as the leader tells you something. you do not hype someone else’s product for fun, coinbase wants that distribution
volume or it didnt happen is fair but armstrong said top client, not top volume. grok could lead logins with tiny tx counts and both things still be true
the phone number porting comparison undersells the problem. agent identity is state plus keys plus payment rails, moving all three together is a decade project
a decade is generous for that porting idea. moving a phone number still takes two support calls, now imagine it with an agent holding real balances
wood going from genome reports to agent wallets at a robinhood summit is the actual story here. whoever wins lock-in wins the fees, she knows it
