Ally Invest vs. M1 Finance (2026): Which One Should You Open?
Both sell themselves as the one account you need, by opposite routes. Ally added investing to a bank; M1 added banking to a portfolio.
Ally if your cash is the centre of gravity. M1 if the portfolio is. Neither is a full replacement for the other, and the weaker half is weak enough to matter.
This is an underserved comparison, because the two companies describe themselves in almost identical language while being built for different people.

On one screen
| ALLY | M1 FINANCE | |
|---|---|---|
| Started as | An online bank | An investing platform |
| Savings | High-yield savings at a competitive high-yield rate that moves with the Fed — Ally publishes the current figure on its savings page, with Buckets | the High-Yield Cash Account is open to all M1 clients, though the rate moves with the rate environment |
| Checking and debit | Full checking, up to $10 a cycle in out-of-network ATM fees reimbursed | M1 Spend, with the Owner’s Rewards Card now closed to new applications |
| Portfolio automation | None — you place trades | Target allocation maintained on every deposit |
| Stock and ETF commissions | $0 | $0 |
| Options | Yes, $0.50 per contract, with no base commission | Not offered |
| When trades happen | Any time the market is open | One daily window around 9:30 am ET, with a second afternoon window near 3:00 pm ET on the paid tier |
| Subscription | None | $3 a month — M1 retired the $125-a-year Plus tier and replaced it with a flat platform fee, waived if your M1 balance touches $10,000 on any day in the billing cycle or you hold an active M1 Personal Loan |
| Retirement accounts | Traditional, Roth, SEP | traditional, Roth, SEP and rollover IRAs, with no minimum beyond the $3 monthly fee below $10,000 |
| Borrowing | Margin | M1 Borrow — a rate that moves with the Fed, published on the provider’s own site |
Both sides carry markers here, and that is deliberate: Ally's rates move monthly and M1's product line has changed repeatedly.
Two routes to one account
Ally's logic: you already keep money in a bank, so put the brokerage next to it. The savings product is the good one and the investing side is adequate.
M1's logic: your portfolio is the thing that matters, so wrap banking around it. The automation is the good part and the banking side is thinner.
Whichever you pick, you are choosing which half you are willing to accept as merely fine.
The banking side compared
Ally wins this clearly. A competitive savings rate, Buckets for splitting savings goals, proper checking, and a long track record as a bank. Our Chime vs. Ally comparison and savings roundup cover it in detail.
M1's cash features exist and have improved, but the terms have moved and some have sat behind the paid tier. Verify what is currently included before treating it as a bank replacement.
The investing side compared
M1 wins this just as clearly, but only if you want automation. Its Pie system maintains a target allocation without you touching it — see our M1 vs. Betterment comparison for how that works in practice.
Ally Invest is a conventional brokerage: you place trades, you rebalance, nothing happens automatically. It also has options, which M1 does not offer at all.
Who each one is wrong for
- M1 is wrong as your primary bank, and wrong for anyone who wants options or same-day execution.
- Ally is wrong for someone who wants an allocation maintained for them, or who will not rebalance by hand.
- Neither is wrong together — Ally for cash, M1 for the long-term allocation. That combination covers both halves properly.
What this means for you
- Emergency fund and everyday money first: Ally.
- A target allocation you want maintained: M1.
- Options anywhere in the plan: Ally. M1 has none.
- You want one login and will compromise: Ally, because a weak brokerage costs you less than a weak bank.
- Both: the cleanest answer if you do not mind two apps.
