We picked this research a little late in the day scrolling, but it provides some interesting data the bears closer interrogation.
It's from @CoinbaseDev, followed by developers of trading agents for the crypto platform.
The bald numbers are as follows
- Grok accounted for 59.54% of notional AI agent trading volume on Coinbase from Sept. 14 to Sept. 21, exchange data shows.
- Anthropic's Claude took 13.37% of the measured volume, custom command-line setups held 21.73%, Perplexity took 3.48%, and OpenAI's ChatGPT trailed with just 1.54%.
Coinbase chief executive Brian Armstrong called Grok "the leading client for agentic traders on Coinbase currently" in a post on X on Sept. 25, prompting a one-word reply from Elon Musk: "Cool."
Grok's share has moved sharply in recent weeks, climbing from 15.3% in an earlier Coinbase snapshot to 59.5% after a native integration went live in early September.
This ranking measures each AI client's share of trading activity rather than total dollar volume, which Coinbase has not disclosed, nor has it named which cryptocurrencies the agents are buying.
Coinbase for Agents launched on 11 June, allowing AI assistants to trade crypto spot and derivatives directly from a user's account, and the exchange extended the feature to US stocks and exchange-traded funds on 22 September.
Grok and Perplexity users access the exchange through a plugin or connector tab, while ChatGPT and Claude connect via the Model Context Protocol; Coinbase's documentation notes that Claude asks for confirmation before placing an order, while ChatGPT executes in a single turn.
Okay, so there's the news, albeit delivered a little late in the day. Here's what it actually means: Distribution beats model quality.
Grok lives inside X, where crypto traders already spend their day, so going from reading a market thread to placing an order is one step.
Grok went from 15.3% to 59.5% in a few weeks on the back of a single integration. So, it has the best plumbing, not the best tech (Claude and ChatGPT are still top class on that score).
Another eye-catcher, which reveals 21.73% held by custom command-line setups. It suggests the committed users are building their own tooling and treating the chatbot brands as optional.
Remember, though, this a snapshot from a single week, it measures share rather than dollars, and Coinbase hasn't published total agent volume or what was traded.
That means a handful of large accounts could have tilted the data. And delving into the volume, at $54 million, is a very small percentage of weekly turnover.
So, the data is interesting, but far from conclusive.
