Already seeing a bunch of lazy bullposting on Twitter. 

What Robinhood is actually launching (based on their blog post):

EU
* US stock & ETF tokens — 200+ assets, 24/5 trading, zero Robinhood commission; live today for eligible users; issued on Arbitrum.
* App expansion — Robinhood Crypto now available in all EU
* Crypto perpetual futures — Up to 3× leverage, orders via Bitstamp; full rollout by end of summer 2025.
* Robinhood Layer 2 blockchain — Arbitrum-based chain for tokenized real-world assets, 24/7 trading, self-custody; in development, date to be announced.

United States
* Crypto staking — ETH and SOL rolling out now to eligible U.S. customers.
* No U.S. launch dates yet for stock tokens, perpetual futures, or the Layer 2 chain.

Stock coins (i.e. tokenized stocks) and perpetual futures in the US is the most valuable prize.

Robinhood might turn stocks into crypto, and let you trade them like a DJ on steroids, 24/7.

If you can bet on Apple at 3 AM on a Sunday, with leverage, without a bank that’s financial crack for traders.

And if they pull it off in the US? Game over.
