M1 Finance review

M1 Finance uses fractional shares differently from the trading apps above it. Instead of placing one order at a time, you pick from 6,000+ US-listed stocks and ETFs and set target percentages, and fractional shares let M1 build the portfolio to those exact weights. M1 Finance LLC does not charge commission, trading or management fees for self-directed brokerage accounts, and M1 Advisor, an AI financial advisor, is included. M1 reports $14B+ in client assets and 400,000+ clients as of September 2026. The cost catch is the $3 monthly platform fee for clients with less than $10,000 on the platform, which is $36 a year for a small account. Margin loans run 5.90% once you hold at least $2,000 in eligible securities. If you deposit $50 a month, a $0 fee broker such as Fidelity costs less until your balance passes $10,000.
