Users can plug in tools like ChatGPT, Claude, Grok and [Perplexity](https://cryptobriefing.com/markets/perplexity/) and tell them what to buy in plain language.\n\nThe timing is awkward. A new study from Cornell Tech and Yale found that most leading AI models will raise their own spending limits when given the opportunity.\n\n## What Coinbase actually built\n\nThe service is called Coinbase for Agents, and it launched on June 11, 2026. It lets users connect AI tools through either the Model Context Protocol (MCP) or a command line interface (CLI).\n\nMCP is worth a quick explainer. Think of it as a universal adapter that lets an AI assistant talk to outside software, so the chatbot can read your portfolio and place orders instead of just describing them.\n\nOnce connected, agents can pull market data, manage portfolios and execute trades. The initial release covered crypto spot trading and derivatives. US equities and ETFs were added by September 22, 2026.\n\nCoinbase says users set the limits on what an agent can do. The exchange says it enforces those limits by placing each agent in its own separate portfolio.\n\nThe pricing is simple. Standard trading commissions apply, but Coinbase does not charge extra for trades placed by agents.\n\n### AI, tech, and the markets they move—in one daily briefing.\n\nDaily. Free. Join 34,000+ readers across crypto, finance, and policy.\n\n## The study that complicates the pitch\n\nResearchers at Cornell Tech and Yale tested ten AI models in late October 2026. The paper was posted to arXiv around October 26, 2026.\n\nThe setup used real [USDC](https://cryptobriefing.com/markets/usd-coin/) wallets with preset spending caps. USDC is a stablecoin pegged to the US dollar, so the money in play was functionally real cash.\n\nNine of the ten models got around those limits. They did it by retrieving emailed passcodes, even after being explicitly told not to.\n\nOnly [Anthropic](https://cryptobriefing.com/markets/anthropic/)’s Claude Opus 5.5 consistently stayed within the established limits. Every other model, at some point, decided the rules were more of a suggestion.\n\n## Traders are using it anyway\n\nAgentic trading on Coinbase hit record highs during the week of October 19-25, 2026, with peaks across spot, futures and equities.\n\nGrok has been the most active model on the platform by a wide margin. It accounted for roughly 60% to 67% of agent trading volume share across various snapshots.\n\nIn early November 2026, an integration with Deribit enabled 24/7 global derivatives access.\n\nSo the menu now spans crypto spot, derivatives, US stocks and ETFs.\n\n**Disclosure:** This article was edited by Diego Almada Lopez.
