Wealthfront Cash Account

Wealthfront Cash Account offers a 4.20% APY with unique FDIC insurance coverage up to $8 million through partnerships with 20+ banks, far exceeding the standard $250,000 limit. Its seamless integration with Wealthfront's investment platform allows automatic sweeps of idle cash into portfolios, a feature not available from Ally or Marcus. Although the APY is 0.05% lower than Marcus, the $8 million protection is 32 times the average savings account insurance, providing unmatched security for high-balance savers.
