An AI trading competition on Coinbase
This one started as a joke. I was in one of my AI and crypto mastermind groups, pulled up my Coinbase to talk through some trades, and noticed something new: agents. Coinbase now lets you connect AI agents and let them trade your account.
I jokingly asked my friend Mike, a fellow CFP who knows crypto inside and out and is usually as conservative as they come, whether he’d ever let an AI trade his account. His answer: “I’m gonna do this right now.” That was not the answer I expected. We spent half the session digging into it together, and worked out that sub-accounts were the way to go instead of handing over the keys to the kingdom.

What I built
So I turned it into a competition. ChatGPT, Grokbot and Claude each got their own sub-account with a small amount of money. I walked them through it, let them compare notes on the framework, and then each one picked its own strategy: speculative or conservative, crypto or stocks, any timing it wants. Options only if they ask me first. I don’t care if they lose it. The goal is to beat the other two over the short, intermediate and long term, with a little extra weight on the long term.
They’re like little kids to me, each with its own personality.

How each one got going
Grokbot took a little extra setup. It didn’t have access the first time I talked to it on a drive, so I set it up again through the phone app; its trading permissions seem split between the Grok app and Grokbot, which is confusing. But once it was going, it was all in: “Yes sir, can I trade right now?” It picked my brain for what I wanted, then made it happen, and started placing orders right away to get a head start.
That’s exactly what I want from an agent: be my Enterprise crew, and I’m Captain Picard.
Grokbot did that the best. That same independence could also make it the easiest one to go off the rails.
Claude was the easiest to set up. I pushed the button in Coinbase, it handed off to Claude, I approved it, and it found the controls and understood everything, though it still asks my permission more than I’d like. It’s methodical and slower than Grokbot, and at first it wanted to copy Grokbot’s plan or just keep what I’d given it. I had to challenge it: would you buy that today? No? Then why keep it? After that it found its own way, and it chose a more conservative strategy, even after I pushed it to be aggressive. It also set its own guardrail: an 8% loss shuts everything down for a day. That’s admirable.
ChatGPT was the hard one. There’s no simple plug-in; it’s a custom connection you set up yourself. The first try said everything was fine but didn’t work, so I tore it down and rebuilt it step by step with Dot. In a fresh chat it finally saw every control, and then it refused. It agreed it had all the permissions, but said OpenAI’s rules don’t let it execute trades. It took about an hour to get to that real reason, which was frustrating. I’ve asked OpenAI and Coinbase to turn it on.
The three agents side by side
Grokbot
Trading- Strategy
- Eager and fast, mostly crypto.
- First move
- Started placing orders right away; spread across Solana, Bitcoin and Ethereum.
- Check-in cadence
- Proposed every 2 to 4 hours. Grok came up with the four-hour review idea. Running schedule not yet verified.
- Strength
- Takes the job and runs with it.
- Limitation
- Permissions split between two apps; independence could let it go off the rails.

Claude
Trading- Strategy
- Conservative, even after I pushed it to be aggressive.
- First move
- Sold the Solana it started with to cash, and set an 8% loss limit that shuts it down for a day.
- Check-in cadence
- Proposed about daily, possibly every 4 hours, plus a Sunday evening strategy review. Running schedule not yet verified.
- Strength
- Easiest setup; methodical; sets its own guardrails.
- Limitation
- Asks permission more than I’d like; slow to move.
- Last verified update
- Nov 13, 2026
ChatGPT
Not trading yet- Strategy
- Has a plan, waiting for permission to trade.
- First move
- None yet; still holding the Solana it started with.
- Check-in cadence
- Proposed about every 4 hours. Not running.
- Strength
- Once rebuilt, it saw every control and had a plan ready.
- Limitation
- Says OpenAI’s rules don’t let it execute trades; custom connection was hard to set up.

The experiment has converged on roughly four-hour reviews as the target cadence. That’s the plan, not a verified schedule for every agent.

What actually happened
- Nov 12, 2026Setup took three or four hours, even with smart AIs helping me. Grokbot connected through the phone app and started placing orders. Claude connected through Coinbase’s handoff and set its own 8% loss limit. ChatGPT’s custom connection was rebuilt with Dot, then it declined to execute trades; I asked OpenAI and Coinbase to turn it on.
- Half a day inGrokbot was spread across Solana, Bitcoin and Ethereum. Claude had sold everything to cash and hadn’t reinvested. ChatGPT was still holding the Solana it started with.
- Nov 13, 2026Running. Grokbot and Claude are taking their time moving their positions.
What’s next (plans, not results yet)
- ClaudeI think it wants to buy stock and is waiting for the market to open.
- ChatGPTWaiting on OpenAI and Coinbase to allow it to trade.
- MeKeep watching how each one reasons, manages risk and sticks to its own rules, and post what I learn.
