M1 has temporarily increased their referral bonus to $250 if you open a new account with $10,000 and maintain it for 30 days. You’ll also get 6 months free of their M1 Plus premium service. Here are the $250 bonus details (the current promo which expires March 31, 2024). Here is my M1 referral link (thanks if you use it!) from which you must start opening your new account. M1 lets you easily create a portfolio of ETFs and buy them all at once with regular contributions and $0 trade commissions.
A bonus that amounts to 2.5% of your initial deposit with only a 30 day hold is pretty solid (technically a 30% annualized yield). This is over 3x better than their non-referral offer (where you’d only get $75 for a $10,000 deposit), and you can stack the ACAT transfer bonus on top (starting at an additional $250 for transfer $50,000 of existing assets from another broker).
