M1 review

M1 sits between a robo advisor and a brokerage. Instead of assigning you a portfolio, it lets you build a Pie, a set of stocks and ETFs with target percentages, and then automates the rest. Auto-invest, on by default, sends each deposit into the Pie, buying underweight slices first so the portfolio drifts back toward your targets without selling anything. You can also rebalance with one click, set a recurring deposit schedule, and ask M1 Advisor, an AI financial advisor included for M1 clients, for guidance based on your accounts. M1 charges no commissions or management fees, only a $3 monthly platform fee that is waived once you hold more than $10,000. M1 reports more than 400,000 clients and over $14 billion in client assets as of September 2026. The catch for this list is that you make the investment choices yourself, and M1 does not describe tax-loss harvesting. Pick it if you want control of the mix with automated upkeep.

Who it is for
