Yes. Though both Betterment and Wealthfront strive to minimize risk and maximize returns by investing your cash in a diversified range of assets, your investments are still susceptible to market swings. Plus, if either robo-advisor were to ever go out of business, each platform offers SIPC insurance of up to $500,000. Betterment also offers FDIC insurance of up to $1 million ($2 million for joint accounts) for its cash reserve accounts and FDIC insurance of up to $250,000 for its checking accounts.
