Bank & Fintech Arbitrage

Fintech Cash Account Yield Arbitrage (Wealthfront/SoFi/Robinhood)

Fintech cash accounts pay 4.5–5% via bank sweep networks — some offer $250 signup bonuses stacked on top.

Overview

Non-bank fintechs (Wealthfront Cash 5.00%, Betterment Cash Reserve 4.75%, Robinhood Gold Brokerage Cash 5.00%, SoFi Money 4.60%, Fidelity CMA 4.98%) partner with FDIC banks to offer checking-like accounts at top-of-market yield. Often include unlimited ATM refunds, no fees, direct deposit early access. Stack sign-up bonuses ($200–$300) with ongoing yield. Watch: introductory rates that revert (Robinhood Gold requires $5/mo membership). Track promotions monthly.
