Fidelity vs Schwab: Which Is Better in 2026?
Fidelity and Charles Schwab are the two full-service brokers serious long-term investors most often choose between. Both clear trades for free, run deep research operations, and offer one-app-for-everything coverage (brokerage, IRAs, mutual funds, cash management). The differences are real but narrow. Below is an honest, balanced look as of 2026, plus where Walnut fits as an AI investing layer on top of either.
At a glance
| Fidelity | Schwab | Walnut (on top) | |
|---|---|---|---|
| Stock & ETF commissions | $0 | $0 | Same, Walnut routes orders to your broker |
| Fractional shares | Yes, any stock/ETF (down to $1) | Stock Slices, S&P 500 only (down to $5) | Yes, uses broker fractional support |
| Zero-expense index funds | Yes (FZROX, FNILX, etc.) | No, low-cost but not zero | Walnut focuses on stocks + ETFs |
| Mutual funds | Thousands, many no-fee | Thousands, many no-fee | Walnut focuses on stocks + ETFs |
| Active-trader platform | Active Trader Pro | thinkorswim (from TD Ameritrade) | AI assistant + web search across either |
| Research & analyst reports | Deep, multiple providers | Deep, Schwab Equity Ratings + providers | AI assistant reads your live positions |
| Built-in AI assistant | Insights, not conversational chat | Limited, no conversational chat | Full agentic AI with your live positions |
| Cash management | Cash Management Account + auto-sweep | Schwab Bank checking + sweep | Inherits broker |
| Robo-advisor | Fidelity Go | Schwab Intelligent Portfolios | Walnut is not a robo, you keep control |
| Trade execution from Walnut | Read-only via SnapTrade | Yes, Schwab trades via SnapTrade | Connect for tracking or trading |
| SIPC insurance | Yes, up to $500K | Yes, up to $500K | Not applicable, Walnut doesn't custody assets |
Trading & fees
Both brokers charge $0 commission on US stocks and ETFs and offer thousands of no-transaction-fee mutual funds. The clearest cost edge goes to Fidelity, whose ZERO index funds(FZROX, FNILX, and others) carry a 0.00% expense ratio, something Schwab's otherwise very cheap lineup doesn't match.
Fractional shares are the other practical difference. Fidelity lets you buy slices of essentially any US stock or ETF down to $1, while Schwab's Stock Slices are limited to S&P 500 names and start at $5. For small-dollar diversification across a wide list, Fidelity is more flexible.
Research & data
This is close to a tie, and both are excellent. Fidelity bundles research from multiple third-party providers (Argus, Zacks, and others), strong screeners, and real-time quotes. Schwab brings its proprietary Schwab Equity Ratings plus the deep research tools it inherited from TD Ameritrade. Either firm gives you far more analytical depth than an app-first broker like Robinhood or Webull.
Trading platforms
For active traders this is where Schwab pulls ahead. Schwab now owns thinkorswim, the platform it acquired with TD Ameritrade, which remains one of the best retail environments for options and technical analysis. Fidelity's Active Trader Pro is genuinely good and arguably cleaner for plain equity trading, but thinkorswim's depth is the benchmark.
For buy-and-hold investors who rarely leave the web dashboard, both platforms are more than enough and the choice barely matters.
Cash management & robo-advice
Both offer a cash-management layer: Fidelity's Cash Management Account with a competitive auto-sweep yield, and Schwab Bank checking integrated with the brokerage. Fidelity has historically been more aggressive on the yield it pays on uninvested cash, which is worth checking if you hold meaningful balances.
Both also run robo-advisors, Fidelity Go and Schwab Intelligent Portfolios, for hands-off investors who want automated allocation. (Walnut is a different model entirely: you keep full control and the AI advises rather than auto-allocates.)
Account types
Both are about as complete as US brokers get: every flavor of IRA, 529 plans, HSAs (Fidelity's HSA is especially well-regarded), custodial accounts, trusts, and business accounts. If you want a single firm to hold your entire financial life, either qualifies. This is the category where both leave the app-first brokers far behind.
Where Walnut fits in
Walnut isn't a broker; it sits on top of one. You connect your existing Fidelity or Schwab account (via the regulated SnapTrade integration) and Walnut adds a layer neither firm has today: an AI assistant that can see your full portfolio, build thematic stock baskets in conversation, run drift analysis, and answer questions like “which of my positions is dragging returns this month?” using your live holdings.
For Walnut users, the practical difference between these two is execution: Schwab supports trade execution from inside Walnut, while Fidelity is read-only via SnapTrade today (track in Walnut, trade in Fidelity). Either way, you keep your existing broker and your money stays where it is.

FAQ
How does Fidelity work?
+
Fidelity is a full-service broker where you can hold a taxable brokerage account, IRAs, a 529, an HSA, mutual funds, and cash management in one place. You fund it from a bank and trade stocks and ETFs commission-free, plus thousands of mutual funds. It offers deep research, fractional shares down to $1, and zero-expense index funds. Fidelity notably does not sell equity order flow.
How much does Fidelity charge?
+
Fidelity charges $0 commission on US stocks and ETFs and $0.65 per options contract. Many index funds carry very low expense ratios, and its ZERO funds charge 0.00%. There is no minimum for a standard brokerage account. Small regulatory fees apply to sells.
How does Schwab work?
+
Charles Schwab is a full-service broker offering brokerage accounts, every flavor of IRA, 529 plans, mutual funds, banking, and a nationwide branch network. You fund it from a bank and trade stocks and ETFs commission-free. Schwab owns the thinkorswim platform (acquired with TD Ameritrade) for active traders, and offers fractional S&P 500 shares (Stock Slices) from $5.
How much does Schwab charge?
+
Schwab charges $0 commission on US stocks and ETFs and $0.65 per options contract. Its index funds and ETFs carry very low expense ratios, and there is no account minimum for a standard brokerage account. As with all brokers, small regulatory fees apply to sells.
How do Fidelity and Schwab make money?
+
Both earn primarily from net interest on cash (a large revenue source for each), fund expense ratios, margin lending, advisory and managed-account services, and securities lending. Fidelity famously does not sell equity order flow. Trading commissions are not a meaningful part of either firm's revenue, which is why both offer $0 stock and ETF trades.
Is Fidelity or Schwab better?
+
They're the two strongest full-service brokers in the US and genuinely close. Fidelity edges ahead on zero-expense index funds, cash-management yields, and flexible fractional shares on any stock. Schwab edges ahead on its thinkorswim platform for active traders and its branch network. For most long-term investors either is an excellent home.
Should I use Fidelity or Schwab?
+
Use Fidelity if you want zero-fee index funds, the best cash management, and fractional shares of any stock. Use Schwab if you want thinkorswim for active or options trading, or value walking into a physical branch. Both are excellent; whichever you choose, you can layer Walnut's AI on top via SnapTrade (and Schwab even supports placing trades from inside Walnut).
Which has better fractional shares?
+
Fidelity, for flexibility. Fidelity's Stocks by the Slice lets you buy fractional shares of essentially any US stock or ETF down to $1. Schwab's Stock Slices are limited to S&P 500 companies and start at $5. If you want to build a small-dollar position in a stock outside the S&P 500, Fidelity is the only one of the two that can do it.
Does Fidelity or Schwab have zero-fee index funds?
+
Fidelity does. Its ZERO funds (FZROX, FNILX, and others) charge a 0.00% expense ratio with no minimum. Schwab's index funds and ETFs are very cheap but not zero. Over decades the difference is small in dollar terms, but Fidelity's zero-fee lineup is a genuine and unique perk for buy-and-hold index investors.
Which has the better trading platform?
+
Schwab, for serious active traders, because it now owns thinkorswim, widely regarded as one of the best retail platforms for options and technical analysis. Fidelity's Active Trader Pro is very capable and arguably cleaner for equities, but thinkorswim's depth on options and charting is hard to beat. For buy-and-hold investing, both web platforms are more than enough.
Which is better for beginners?
+
Both are beginner-friendly, with a slight edge to Fidelity for simplicity and its any-stock $1 fractional shares, which make it easy to start small. Schwab is just as solid and arguably better if you expect to grow into active trading via thinkorswim. Neither is a wrong choice for a first brokerage.
Can I transfer my account between Fidelity and Schwab?
+
Yes. Both support ACATS transfers, so your positions and cost basis move over and you generally don't have to sell anything. Transfers usually take 5-7 business days. Both brokers periodically offer transfer-fee reimbursement or cash bonuses for moving qualifying balances, so it's worth checking current promotions.
Which is safer, Fidelity or Schwab?
+
Equivalent. Both are SIPC-insured up to $500K (with a $250K cash sub-limit) and both carry large supplemental insurance through their custodians. Both are long-established, heavily regulated firms managing trillions in assets. Asset safety is not a meaningful differentiator; the decision should come down to products and tools.
Does Fidelity or Schwab have a real AI assistant?
+
Not in the conversational sense yet. Fidelity Insights surfaces personalized market commentary, and Schwab offers research tools and ratings, but neither is a chat-style AI that can manage your portfolio. Both firms are cautious with AI given their regulated wealth-management businesses. For AI as the main interface to your holdings, a dedicated AI investing app like Walnut goes further.
Can I use Walnut with Fidelity or Schwab?
+
Yes. Both connect through the regulated SnapTrade integration. Schwab supports trade execution from inside Walnut, so you can place real orders against your baskets. Fidelity is read-only via SnapTrade today, so Walnut tracks your positions and adds an AI assistant, basket-building, and drift analysis on top while you trade in Fidelity's own apps.
