The Wealth Wingwoman Audit
Audited by Valerie Vance"The matchup between M1 Finance and Public.com is a head-to-head clash between two modern fintech architectures built for retail investors: Chicago’s automated, passive “finance super app” built around algorithmic target-weight Pies versus New York’s multi-asset investing platform that disrupted payment-for-order-flow (PFOF) and turned options order routing into cash rebates. Both platforms are US broker-dealers regulated by the SEC and FINRA, backstopped by statutory SIPC coverage ($500,000 protection, including $250,000 for cash claims) alongside private excess SIPC policies. Both offer $0 base commissions on standard US-listed stocks and ETFs, support fractional share investing, and provide high-yield cash management rails. Assuming they deliver an interchangeable investing experience because both are smartphone-first fintech apps is an expensive mistake. One desk is an automated compounding machine built strictly around long-term portfolio rules: executing trades in rigid daily windows, automatically allocating new deposits into underweight holdings via Dynamic Rebalancing, and offering low-cost portfolio lines of credit (M1 Borrow)—while penalizing accounts under $10,000 with a $3/month platform fee. The other is an agile multi-asset brokerage: offering real-time market execution, direct access to Treasury accounts (exempt from state income tax), corporate bonds, cryptocurrency, a 1% IRA match, and an options rebate program that pays you $0.06 to $0.18 per contract instead of charging you a commission."
The Tale of the Tape
M1 Finance (founded in 2015) is built for disciplined, hands-off wealth accumulators who want to manage their assets like an institutional endowment. It is structured around M1 Pies: customizable portfolios where you set target percentage allocations across individual stocks and ETFs. Instead of executing discretionary intraday trades, M1 batches client orders into one or two daily trading windows, using algorithmic dynamic rebalancing to funnel new deposits and dividend payouts into whichever assets are lagging behind their target weights.
Public.com (founded in 2019) is a modern multi-asset investing platform serving millions of self-directed investors. Initially recognized for rejecting equity PFOF in favor of a transparent routing and tipping model, Public expanded into a comprehensive retail workstation: offering real-time equity execution, fractional shares from $1, high-yield Treasury Accounts (direct US T-bills), corporate bond baskets, crypto trading, an AI fundamental research engine (Alpha), and an options trading desk that shares order-flow revenue directly with clients.
The Fine Print Reality Check
Marketing teams pitch commission-free investing, but your actual net returns are dictated by platform subscription thresholds, execution timing mechanics, options revenue sharing, fixed-income tax efficiency, and portfolio rebalancing plumbing:
- The Small-Balance Penalty ($3/Month Fee vs. $0 Maintenance): M1 Finance charges a mandatory $3 monthly platform fee ($36/year) on all accounts unless your total aggregate M1 platform assets reach at least $10,000. On a $1,000 portfolio, M1’s $36/year fee acts as a brutal 3.60% annual drag. Public.com enforces $0 monthly platform maintenance fees and $0 minimum account balances on its standard tier.
- Execution Architecture (Rigid Trading Windows vs. Real-Time Market Orders): M1 Finance is designed to eliminate emotional day trading. M1 provides no real-time market or limit order execution. All trading occurs during set windows: a morning window at 9:30 AM ET and an afternoon window at 3:00 PM ET. Public.com operates as a standard real-time brokerage. You can place real-time market orders, limit orders, and stop orders throughout regular market hours, as well as participate in pre-market and after-hours trading sessions.
- Portfolio Automation & Dynamic Rebalancing (The M1 Moat): M1 Finance is the undisputed industry leader in automated, passive cash deployment. M1’s Dynamic Rebalancing algorithm calculates which asset has fallen furthest below its target percentage and routes the cash to that slice. Public.com offers automated recurring investments, allowing you to dollar-cost average on a set schedule. However, it offers no automated target-weight rebalancing.
- Options Trading: Paying You to Trade vs. Total Exclusion: Public.com offers an Options Order Flow Rebate Program. Public charges $0 commission and pays you a cash rebate of $0.06 to $0.18 per contract traded (based on monthly trading volume tiers). M1 Finance provides zero options trading capabilities.
- Fixed Income & State Tax Efficiency (Treasury Accounts vs. Cash Accounts): Public.com features dedicated Treasury Accounts that allow you to invest directly in a customizable ladder of US Treasury bills. Interest earned from US Treasuries is 100% exempt from state and local income taxes. M1 Finance does not offer direct individual Treasury bill purchases or corporate bonds. Fixed income must be accessed through exchange-traded funds (such as SGOV or BND) or parked in M1's High-Yield Cash Account (where interest is fully subject to state and federal income taxes).
- Retirement Incentives (1% Match vs. $3 IRA Fee): Public.com offers Traditional and Roth IRAs with an uncapped 1% match on annual contributions and rollover transfers. M1 Finance offers IRAs, but provides zero contribution matching. If you hold only an IRA on M1 and your balance is below $10,000, M1 assesses its $3/month IRA fee.
The Fine Print Translation
M1 Finance is an automated compounding machine built strictly around long-term portfolio rules: executing trades in rigid daily windows, automatically allocating new deposits into underweight holdings via Dynamic Rebalancing, and offering low-cost portfolio lines of credit—while penalizing accounts under $10,000 with a $3/month platform fee. Public.com is an agile multi-asset brokerage: offering real-time market execution, direct access to Treasury accounts, corporate bonds, a 1% IRA match, and an options rebate program that pays you $0.06 to $0.18 per contract.
The Daily Driver Test
Your platform experience depends entirely on whether you want an automated portfolio machine that manages allocations in the background or a multi-asset brokerage for tactical investing.
M1 Finance operates like an automated family office. The interface is organized around visual circular 'Pies.' You assemble your long-term asset allocation once, set up a recurring weekly bank transfer, and step away. When deposits clear or dividends roll in, M1’s dynamic rebalancing automatically executes purchases during the morning window to feed your most underweight assets. You never have to calculate how many fractional shares to purchase or worry about portfolio drift. However, if you see a breaking news headline at 11:00 AM and want to buy an equity dip instantly, M1 will frustrate you: your trade will sit queued until the next scheduled trading window.
Public.com operates like a modern, multi-asset trading desk. Opening the app gives you instant access to streaming real-time market prices, company earnings transcripts, and an AI research assistant (Alpha) that answers fundamental balance sheet queries. Placing an immediate limit order on an equity takes seconds. If you want to build a low-risk cash runway, opening a Treasury Account allows you to lock in short-term government yields while avoiding state income tax. When trading options, Public's interface clearly calculates your expected cash rebate directly on the checkout screen before you submit your ticket.
The Wingwoman Allocation
Don’t pay a $3 monthly fee on a small balance at M1, and don’t execute manual portfolio math if your goal is set-it-and-forget-it indexing:
- Deploy with Public.com if: Your investment portfolio is currently under $10,000, keeping 100% of your capital compounding without M1's $36/year fee drag. You live in a high-tax state and want to open a Public Treasury Account to buy direct US Treasury bills and lock in 100% exemption from state and local income taxes. You actively trade options contracts and want to enroll in Public’s Options Order Flow Rebate Program to capture a cash rebate of $0.06 to $0.18 per contract. You are funding an annual IRA to capture the 1% match on your annual contributions and rollover transfers.
- Deploy with M1 Finance if: You hold $10,000+ in total assets and want an automated portfolio, which permanently waives the $3 monthly platform fee. You want to build a custom Pie and schedule recurring weekly or monthly deposits so M1’s dynamic rebalancing algorithm will automatically deploy every dollar into underweight assets. You want a low-friction portfolio line of credit utilizing M1 Borrow to access margin borrowing against your taxable portfolio for personal liquidity needs.
Your Wingwoman Move
If your balance is currently under $10,000, or if your strategy requires real-time order execution, options trading, or state-tax-exempt US Treasury bills, Public.com is the clear winner. Public eliminates the $36 annual fee penalty that drags down small accounts on M1, provides direct access to government debt and corporate bonds, pays an uncapped 1% match on IRA contributions, and actually pays you cash rebates to execute options trades.
However, once you have $10,000+ in capital and your sole objective is building a passive, long-term wealth engine that manages itself, M1 Finance is an exceptional portfolio operating system. The mathematical efficiency of M1’s Dynamic Rebalancing—funneling new cash and dividends directly into underweight slices to preserve your target asset allocation without triggering taxable capital gains—provides automated portfolio management that Public cannot replicate. Use Public to compound accounts under $10,000, trade options for cash rebates, and lock in state-tax-free yields in Treasury Accounts; switch to M1 once you cross the $10,000 threshold if your priority is hands-off, automated portfolio rebalancing. Go get paid.
