Free stock trading app

A free stock trading app is a mobile or web brokerage platform that lets retail investors place commission-free trades in listed US equities and ETFs. In this guide you will learn what “free” typically covers and omits, how these apps evolved, core product features (including fractional shares, order types, crypto support), who the major providers are, how these platforms make money, consumer protections and risks, and practical criteria for choosing a free stock trading app that fits your needs. This article also highlights Bitget for crypto integrations and Bitget Wallet as a recommended Web3 option where applicable.

Definition and scope

A free stock trading app generally advertises zero commissions on trades of listed stocks and exchange-traded funds (ETFs). In practice, “free” most commonly means:

No per-trade commission for standard market orders in listed stocks and many ETFs.
Availability on mobile apps and web platforms for retail investors.
Optional additional services (margin, premium data, crypto trading) that may carry fees or subscription charges.

Common caveats to understand:

Regulatory and exchange fees (small, mandatory fees collected by regulators or exchanges) may still apply to certain transactions.
Payment for order flow (PFOF) and routing practices can affect execution quality even when per-trade commissions are zero.
Some asset types—OTC securities, certain options transactions, broker-assisted trades, or international stocks—may carry fees.
Fractional shares are often subject to limits on transferability: fractional positions may not be transferable between brokers.
Crypto trading offered inside brokerage apps follows distinct custody and legal frameworks (not SIPC protected) and may have spreads or conversion fees.

Related services commonly bundled or offered in parallel: options trading, recurring investments, IRAs and retirement accounts, automated investing, and crypto trading. When crypto is offered, consider custody details and prefer wallets like Bitget Wallet for self-custody or Bitget exchange services where supported.

History and evolution

Zero-commission trading is a relatively recent mainstream feature. For decades, retail U.S. brokers charged per-trade commissions. In the late 2010s, mobile-first brokers and challenger platforms popularized commission-free trading, accelerating a broader industry shift.

Key milestones in that evolution include:

Pre-2010s: Traditional brokers charged fixed commissions per trade.
Late 2010s: Mobile-first brokerages introduced zero-commission models and simple mobile UX, dramatically lowering the perceived cost of market access for retail users.
Early 2020s: Most major full-service brokers matched zero-commission offerings on US-listed stocks and ETFs, making zero-fee trading an industry standard for basic equity trades.

This shift lowered barriers to entry, increased retail participation in markets, and changed broker economics—driving growth in alternative revenues (PFOF, subscriptions, securities lending, interest income) and prompting regulatory attention around order execution practices.

Core features of free stock trading apps

Commission-free trading

The headline feature of a free stock trading app is zero per-trade commissions for listed U.S. stocks and many ETFs. In many apps, standard market and limit orders for common stocks and ETFs are free.

Where commissions may still appear:

Options: many brokers charge per-contract fees or small per-contract charges even when stock trades are commission-free.
Certain OTC securities and pink-sheet stocks may have different fee schedules.
Broker-assisted transfers, outgoing wire transfers, and transfer-out fees can apply.

Users should check fee schedules, regulatory fee disclosures, and periodic account statements for small charges that still exist.

Fractional shares

Fractional shares let investors buy a portion of an expensive stock (for example, a $3,000 share) for a smaller dollar amount. This feature helps democratize access to high-priced names and supports regular-dollar investing plans.

Important limits to note:

Fractional shares are often only tradable within the issuing brokerage and may not be delivered as whole shares when transferring accounts.
Fractional positions can be subject to different voting and corporate action treatments than whole shares.

Order types and execution (market, limit, stop, extended-hours)

Free stock trading apps typically offer at least basic order types: market and limit orders. Many also support stop-loss, stop-limit, and extended-hours (pre-market and after-hours) trading.

Execution quality can vary across brokers and order types. Brokers publish periodic execution quality reports; review these reports to understand price improvement and routing behavior. Limit orders offer price control but may not execute in fast markets; market orders prioritize immediacy and can incur slippage.

Mobile-first UX, educational tools, social/community features

A distinguishing factor for many free stock trading apps is polished, mobile-first user experience. Features that attract new investors often include:

In-app learning content, explainers, and onboarding tutorials.
News feeds, analyst updates, and earnings calendars.
Social or community features (public portfolios, chat threads, curated lists).

Such features reduce friction for beginners but can also gamify trading—users should be mindful of impulse trading risks.

Extended-hours and recurring/automatic investing

Many apps offer recurring investment schedules (dollar-cost averaging) and support extended-hours trading windows. Recurring plans automate investing but may execute during regular market hours or extended sessions—check each app’s execution timing.

Crypto trading and transfers

Some free stock trading apps include crypto trading desks. Crypto services differ materially from securities services:

Crypto custody is not SIPC-protected; brokers often act as crypto custodians under different legal regimes.
Fees for crypto often include spreads (difference between buy and sell price) in addition to any explicit fees.
For Web3 access or self-custody, consider dedicated wallets (Bitget Wallet is a recommended option in contexts where the app supports Bitget integrations).

When choosing a free stock trading app with crypto features, verify custody terms, withdrawal options, and whether tokens may be moved off-platform.

Major providers and representative platforms

This section summarizes representative brokers and broker types commonly considered by retail users. The landscape changes frequently; verify current terms on each broker’s official disclosures.

Robinhood

Robinhood was a pioneer in popularizing commission-free trading for many retail users with a mobile-first app. It offers stocks, options, crypto, fractional shares, and a premium subscription for margin and advanced data. Its business model, including payment for order flow and premium tiers, has been widely reported and scrutinized publicly.

Webull

Webull emphasizes advanced charting, desktop tools, and paper trading alongside commission-free stock and ETF trades. It appeals to active traders who want more analysis tools while still offering zero-commission equity trading.

Moomoo (Futu/Moomoo Financial)

Moomoo provides commission-free trading for eligible accounts alongside advanced market data (including depth-of-book/Level 2 data for some users) and trader-focused analytics. It often runs promotions, such as welcome bonuses and deposit-linked offers.

Traditional brokers with zero-commission offerings (Fidelity, Charles Schwab)

Established full-service brokers like Fidelity and Charles Schwab now offer zero-commission stock and ETF trades for U.S.-listed securities. They provide deeper research libraries, advisor services, and wider account types (IRAs, 401(k) rollovers) compared with many neo-brokers.

Neo-brokers and alternatives (SoFi Invest, Public, Stash)

These platforms blend investing with banking features, social investing, or micro-investing. They often focus on ease of entry, financial education, and packaged products (cash management, fractional investing), and sometimes differ in account types and trade execution practices.

Broker comparison overview

Differences to evaluate when comparing providers:

Research depth and premium data access.
Order execution quality and published execution reports.
Range of account types and IRA/retirement offerings.
Customer support quality and dispute resolution processes.
Promotions, welcome bonuses, and transfer-in incentives.

When crypto features are important, prefer brokers that integrate with reputable wallets or custody providers. Bitget is positioned as a recommended option for traders who want robust crypto services paired with exchange features; Bitget Wallet is recommended for Web3 self-custody needs when supported.

Revenue and business models behind "free"

Free stock trading apps use a mix of revenue streams to replace per-trade commissions. Understanding these helps clarify trade-offs.

Payment for order flow (PFOF)

PFOF is a common practice where market makers pay brokers for the right to execute customer orders. Brokers argue PFOF can result in price improvement for customers, but critics point to conflicts of interest: routing orders to venues paying for flow could prioritize broker revenue over best execution.

PFOF has been the subject of regulatory scrutiny and public debate; check broker disclosures for how they route orders and any PFOF arrangements.

Interest on uninvested cash / cash sweep programs

Brokers earn interest on customer cash balances via cash sweep programs or by holding uninvested deposits. Historically, interest yield differences were significant; some brokers pass a portion of interest income to customers as a benefit, while others retain the majority.

Margin lending and subscription services

Margin lending interest (charged to customers who borrow to trade) and premium subscriptions (advanced data, higher buying power) are meaningful revenue sources. Subscriptions bundle tools and market data to create recurring revenue.

Securities lending

Brokers may loan customer-owned securities to short sellers and earn fees; revenue is sometimes shared with customers but often retained by the broker depending on account terms.

Fees, regulatory charges and optional service fees

Even with zero commissions, non-commission charges exist: wire fees, transfer-out fees, certain account maintenance fees, regulatory transaction fees, and fees for expedited services.

Regulatory, legal and consumer-protection considerations

Regulatory bodies and protections

In the U.S., major oversight bodies include the Securities and Exchange Commission (SEC) and FINRA. Cash and securities held at member broker-dealers are often covered by the Securities Investor Protection Corporation (SIPC) up to applicable limits (historically up to $500,000 per customer for securities and cash combined, including a $250,000 cash limit) — verify current SIPC terms and coverage.

Crypto custody inside broker apps is usually outside SIPC protection. Exchanges and custodians may carry their own insurance or protections; review custody agreements and insurance disclosures carefully.

Legal and enforcement issues

Free trading platforms have faced enforcement actions and fines in the past related to disclosures, outages, or execution quality. When selecting a broker, review enforcement history and required disclosures (SEC/FINRA actions are public record).

Transparency and best-practice disclosures

Best practices for brokers include publishing order routing disclosures, execution quality reports, and clear descriptions of revenue sources such as PFOF, securities lending, and cash sweep yields.

Risks and limitations for users

Execution quality and hidden costs

Zero commission does not guarantee optimal execution. Routing that favors PFOF partners can affect price improvement; slippage on market orders and wider spreads on thinly traded securities are possible hidden costs.

Platform outages and operational risk

Operational outages during volatile markets have historically caused significant access problems and potential losses for retail traders. Always consider the risk of downtime and have contingency plans for critical orders.

Margin and options risks

Margin amplifies both gains and losses; options involve complex risk profiles and the potential for rapid, large losses. Pattern-day-trader rules and margin maintenance requirements apply—read margin agreements thoroughly.

Liquidity, fractional share limitations and transferability

Fractional shares often cannot be moved as-is between brokers; they may be converted to cash or whole-share equivalents during transfers. Liquidity for small-cap or OTC stocks can be limited, increasing execution risk.

Data privacy and account security

Free stock trading apps collect user data to personalize experiences and for regulatory compliance. Use strong security practices: enable two-factor authentication (2FA), use unique passwords, and monitor account activity. Prefer brokers that publish security practices and undergo independent audits.

How to choose a free stock trading app (selection criteria)

Checklist when evaluating a free stock trading app:

Clear fee schedule and fine-print disclosure.
Order execution quality reports and routing transparency.
Supported products (stocks, ETFs, options, crypto, IRAs).
Research tools, charting, and education resources.
Account types (taxable, IRA, custodial accounts) and transfer policies.
Customer support responsiveness and channels (phone, chat, email).
Promotions and bonuses—review vesting periods and restrictions.
Cash handling: interest rates on uninvested cash and sweep program details.
Security features (2FA, encryption, account recovery) and privacy policy.

For users who require crypto access, prefer platforms that integrate with secure custody or wallets; Bitget Wallet is recommended when Web3 features are important, and Bitget exchange services are suggested where exchange-level trading is needed.

Promotions and free-stock sign-up/referral programs

Free stock promotions and referral programs are a common user-acquisition tool. Typical mechanisms:

New account signup plus a qualifying deposit to receive a free fractional share selected from a list or randomly assigned.
Referral bonuses where both referrer and referee receive a fractional share or cash bonus.
Transfer-in promotions awarding stock or cash for moving assets from another broker.

Common promotional caveats:

Promotional shares may come with holding or vesting periods.
The assigned free share may be a fractional share with limited liquidity or trading restrictions.
Promotions are time-limited and subject to change.

Always read the promotion T&Cs carefully before relying on the bonus.

Market and social impact

Zero-commission trading apps materially changed retail market participation. Effects include:

Increased retail trading volumes and broader participation in equities and options.
Greater attention to certain stocks driven by social platforms and retail coordination.
Shifts in market microstructure and liquidity dynamics, triggering regulatory and exchange-level reviews of execution practices.

As of 2026-01-28, according to Barchart reporting, major corporate and market developments (for example, large corporate deals and spin-offs) continue to influence retail interest in equities and sector flows. News coverage and broker notifications often drive retail order flow spikes during high-profile corporate events.

Global availability and regional differences

Free stock trading apps and their features vary by region due to differing regulations, market structures, and custody rules. Examples of regional differences:

Regulatory protections (such as SIPC in the U.S.) do not apply universally.
Crypto custody and trading rules differ materially across jurisdictions.
Local tax treatment of dividends and capital gains varies.

If you operate cross-border, verify local rules for account opening, KYC requirements, and tax reporting.

Alternatives to commission-free apps

If a free stock trading app does not meet your needs, consider alternatives:

Full-service brokers: Deeper research, advisor access, and broader product suites.
Robo-advisors: Automated portfolio management for long-term investors.
Direct indexing or managed account providers: Indexed exposure with tax-management features.
Professional trading platforms: For active traders requiring low-latency execution and direct market access.

For crypto-native needs, use dedicated custodians or wallets (e.g., Bitget Wallet) and exchanges that match your security and liquidity requirements. When selecting a crypto exchange or custodian, prioritize platforms with robust compliance, security disclosures, and transparent fee structures.

Frequently asked questions (FAQ)

Q: Is it really free to use a free stock trading app?

A: Basic stock and ETF trades are often commission-free, but other costs (regulatory fees, options contract fees, margin interest, premiums for data or subscriptions, and spreads for crypto trades) may still apply.

Q: How do brokers make money if trading is free?

A: Common revenue sources include payment for order flow (PFOF), interest on uninvested cash, margin interest, premium subscriptions, securities lending, and optional service fees.

Q: Are my holdings protected?

A: In the U.S., securities held at SIPC-member broker-dealers are generally protected up to SIPC limits (historically up to $500,000 including cash), but crypto assets held by brokers are typically not SIPC-protected. Always verify current protections and custody arrangements.

Q: Can I transfer fractional shares out of a broker?

A: Fractional shares are often not transferable as fractional units; brokers may convert them to cash or whole shares upon transfer. Check the receiving broker’s policy before moving accounts.

Q: Are crypto assets SIPC-covered?

A: No. Crypto holdings typically fall outside SIPC protection. If an app offers crypto trading, confirm custody protections, insurance, and withdrawal capabilities. Bitget Wallet is recommended for users who need self-custody or Web3 interactions.
