Onchain apps hit Robinhood and Coinbase

Result

If held over the last 3 months (Jul 30, 2026 – Oct 29, 2026): −8.6%. Over the same days: S&P 500 +5.3%.

What it holds

• Brokers lose, 100% of the money, +0.8% over 3 months: against HOOD (Robinhood), against COIN (Coinbase). Onchain apps take trading volume from brokers.

The plan behind it

Beanie wrote on 15 Oct that onchain trading apps will do to online brokers what prediction markets did to sports books. He says Robinhood and Coinbase are in the most trouble. This holds both short, in equal parts.

Onchain trading apps will do to the existing heavily regulated and high barrier online brokers what prediction markets did to the sports book stocks. The bleeding edge platforms like Robinhood and Coinbase are in the most trouble. Just like DraftKings and FanDuel were a year ago.

What would prove it wrong: Robinhood and Coinbase keep growing trading volume as onchain apps grow.

FAQ

Can I make one from my own idea?

Yes. Write what you believe in plain words at https://f.xyz/create. fxyz asks a couple of questions, builds the portfolio and shows how it would have done over the last 3 months.

Can I turn a post on X into a theory?

Yes. Reply to the post and tag @fxyzai. It tests the view in the post and replies with the 3-month result and a link.

What can it trade?

Stocks (Tesla, Apple, Nvidia), crypto (Bitcoin, Ethereum, Solana), pre-IPO companies (OpenAI, Anthropic), indices (Nasdaq 100, S&P 500), commodities (gold, silver, oil, copper) and currencies (EUR/USD, USD/JPY). One theory can mix them, and bet for or against any of them.

How does it react to news?

On each check it reads the last two days of news on its biggest holdings and says whether the idea still holds. It can make one small change at a time: trim or drop one holding by up to 5 points. On autopilot the change waits 10 minutes so the owner can skip it; otherwise it asks first.

How do I run it with real money?

For real money, tap Make it mine, open your copy and choose Use real money, with an exchange connected: Hyperliquid, Lighter, Lighter (Robinhood), Backpack, Pacifica or Binance. The money stays in your own account there. fxyz can place trades, but it can never withdraw.

Can the AI get it wrong?

Yes. fxyz's AI turns the idea into holdings, and it can get that wrong: add a coin or stock that doesn't fit, or miss one that does. Check the holdings before you put money in. In your own copy, ask its chat to add or drop any of them.

What do the 3-month numbers mean?

What $100 would have done holding this mix over the last 3 months, at real prices. It is a what-if, not a record: past or simulated results are no promise of future ones, and nothing here is investment advice.
