Stonkfly, a trading experiment that feeds stock market charts into a simulated fly brain and records its decision

Robinhood
Joined September 2026
Tiny update, huge for us: the fly is in profit 🪰 +6.37 USDG on Robinhood equity perps, 1,250+ observations deep, and genuinely trading better than its first run. It even ate a −2.00 loss and kept going. Proud of the little guy. Every single decision is on record → stonkfly.com
Good morning. Overnight the fly's brain stalled - no decisions for several hours. That's on us, not the fly. Honest take: we rushed the front-end and the way we presented v1. It got out ahead of the engineering. That was the wrong order and. The current experiment keeps running and collecting data. Currently 650+ observations. Behind it, we're rebuilding a heavier version than anything shown so far. Docs, devlog, and more updates start this weekend.

The fly was learning to trade. Then it lost money to fees instead. Quick fix, fresh run. It's back at the desk. Still learning. Whether it learns how to get rich is the whole experiment. stonkfly.com

We gave the fly brain $1,700 to trade stock perps on @RobinhoodCrypto. Same wiring: profit lights up the dopamine neurons, losses hit the aversive ones. Neuron activity calls buy/sell/hold and the orders go to Robinhood. Trading live right now stonkfly.com
I gave the fly brain $100 to trade bitcoin. Dopamine neurons are stimulated when the fly makes profit. Neuron activity controls buy/sell decisions and makes trades on coinbase. Will the fly get rich?

Updated version of the website will follow. Thanks for the patience. We've forked the original Stonkfly repo and are adapting it to our ecosystem on Robinhood Chain. Over ten years of building online, and a fly reading a chart still gets me. Let's see where it goes 🪰

Wall Street trades on gut. Stonkfly trades on 166,700 fly neurons and a dopamine drip tied to P&L. You pay the fee, the fly gets funded, holders get stocks. Nobody knows what happens next — that's the experiment.

3/3 tax on $STONKFLY. Half funds the fly's trading account. Half converts to dividends for holders. Contract that routes every txn is deploying. Webpage + docs coming with it. Fly trades, you get stocks, every decision logged in public. stonkfly.com
