ARK Invest CEO Cathie Wood says investors may soon need to “follow the agents” as AI software moves beyond answering questions to choosing services and spending money. Speaking at Robinhood’s Summit in Houston, Wood extended her longstanding advice to “follow the developers” to a potential new source of demand: the decisions AI agents make. Those decisions could include buying data, paying for API access and renting computing power.
Why it matters
Agents need payment systems as well as software. BlackRock has argued that machine-to-machine purchases could create demand for payment rails built for automated transactions. Stablecoins can move around the clock, while blockchain-based protocols can support small payments between services. Coinbase’s x402 is designed to let machines pay for online resources such as data and API access.
The question is who controls those rails. SharpLink co-CEO Joseph Chalom has argued for open networks, user-set spending limits, revocable permissions and transaction records. He also wants people to be able to move an agent’s identity and permissions between providers. He sees a role for blockchains such as Ethereum in avoiding dependence on a handful of financial or technology companies.
Market impact
For crypto investors, Wood’s framework shifts attention from what agents can do to where they actually transact. Activity on stablecoin and blockchain rails would offer evidence of adoption; activity concentrated on conventional payment networks would point elsewhere. Neither outcome is settled.
Crypto faces substantial competition. Stripe, Visa, Google and OpenAI are developing ways for agents to make purchases, and BlackRock expects traditional payment systems to remain important. The investable signal will be observable payment activity, not the promise of agentic commerce alone.
Frequently asked questions
-
What does Cathie Wood mean by “follow the agents”?
Wood suggests investors watch which services and financial networks AI agents choose as they begin carrying out tasks and spending money.
-
What might AI agents need to pay for?
Examples include data, API access and computing power. These purchases could require payment systems suited to automated transactions.
-
Why are stablecoins part of the agent-payment discussion?
Stablecoins can move around the clock, and blockchain-based protocols can support small payments between software services.
-
What controls does Joseph Chalom want for agent spending?
Chalom argues for user-set spending limits, revocable authority, transaction records and the ability to move an agent’s identity and permissions between providers.
-
How can investors assess whether crypto payment rails gain traction with AI agents?
They can watch where agents actually transact. Use of stablecoin and blockchain rails would provide evidence of adoption, while activity on conventional networks would point elsewhere.
