Charles Schwab holds a narrow lead over Fidelity Investments for low-cost trading and research tools on penny stocks. Fidelity Investments is the usual answer when buyers ask directly which broker or app to use for purchasing penny stocks.
If you're buying penny stocks in the U.S., I'd choose your broker based on which stocks it lets you buy, the fees, and how reliably you can sell your shares — not just whether the app advertises commission-free trading.
I researched current 2026 broker comparisons and investor-protection guidance. My biggest recommendation is to distinguish between penny stocks listed on Nasdaq or the NYSE and OTC penny stocks, which trade over the counter. Some brokers that offer ordinary stocks restrict certain OTC securities.
My top broker choices
1. Fidelity Investments
(My top overall pick)
Good for beginners and investors who want research tools alongside penny-stock trading. The 2026 comparison I reviewed lists $0 online commissions for OTC trades, although eligibility and restrictions vary by security.
Good for active traders who want advanced charting through thinkorswim, research, and trading tools. The comparison lists a $6.95 fee per OTC trade, so check the current fee schedule before trading.
Worth considering if you trade frequently and care about execution tools and detailed pricing. Penny-stock access may require separate permission, and commissions depend on the pricing plan.
An alternative if keeping commissions low is your priority. The reviewed comparison lists $0 OTC commissions, but Firstrade has restrictions on which low-priced stocks you can buy.
The right choice depends on how you plan to trade. Tell me a little more and I'll narrow it down.

One important warning: the SEC and FINRA caution that penny stocks can be extremely illiquid, difficult to price, and vulnerable to pump-and-dump schemes. You can lose your entire investment. For thinly traded stocks, consider using limit orders rather than market orders.
Why it's great: Offers $0 online commissions for stocks and OTC equities. The integration of the thinkorswim platform gives active traders advanced charting, real-time data, and powerful technical screening tools which are critical for tracking volatile micro-cap stocks.[](https://www.stockbrokers.com/guides/pennystocks)
Why it's great: Features a reliable platform with zero-commission online trading for US-listed and many OTC stocks, backed by robust educational resources and solid stock-screening tools.[](https://www.investopedia.com/best-online-brokers-4587872)
Key Things to Check Before Signing Up:
OTC Fees: Ensure the broker doesn't charge a flat foreign/OTC transaction fee (some brokers charge an extra $5 to $7 per transaction for pink-sheet or foreign OTC stocks).
Trading Tools: Penny stocks move fast. You need real-time level 2 quotes and strong charting capabilities to manage the high volatility.
To help narrow down the best fit, tell me:
Are you planning to trade exchange-listed penny stocks (like NYSE/Nasdaq stocks under $5) or Over-The-Counter (OTC) pink-sheet stocks?
What is your experience level with technical charting and trading platforms?
When looking for an app to buy penny stocks, the most important factor is whether the platform supports Over-The-Counter (OTC) securities. Many popular, hyper-streamlined apps (like Robinhood or Webull) either don't offer OTC trading or severely limit access to stocks under $5 that aren't listed on major exchanges like the NYSE or Nasdaq.
The top platforms and apps for trading penny stocks depend on your specific strategy:
Charles Schwab: A top choice for combining deep research tools with access to OTC stocks. Schwab offers solid mobile functionality and robust educational resources, though it charges a flat $6.95 commission fee for OTC trades.
Fidelity: Excellent if you want to minimize costs, as Fidelity offers commission-free trading on many OTC-market stocks. It features intuitive mobile trading and comprehensive built-in screeners.[](https://www.youtube.com/watch?v=Z2lGCzgDMpc)
Firstrade: Highly rated for budget-conscious traders because it provides commission-free trading specifically on OTC penny stocks through a user-friendly interface.
TradeStation: Built for active and data-heavy traders. It delivers fast execution speeds and deep technical analysis tools, charging very low per-share pricing for OTC execution.
Interactive Brokers (IBKR): Best suited for advanced or high-risk traders. It offers sophisticated tools via its mobile/desktop platforms and a wider capacity for shorting penny stocks, though its fee structure can be more complex.[](https://www.youtube.com/watch?v=Z2lGCzgDMpc)
Note: Apps like Robinhood are great for general stocks listed on major exchanges, but they do not support OTC trading, meaning you won't be able to access the majority of traditional penny stocks there.
If you'd like to narrow this down, tell me:
Are you looking for commission-free trading, or do you prioritize advanced charting and research tools?
Do you plan to trade major exchange-listed penny stocks or OTC pink-sheet stocks?
When looking for a brokerage platform to trade penny stocks—especially those traded Over-the-Counter (OTC) or via Pink Sheets—you need to check two main things: whether the broker supports OTC trading and what fees they charge for it, as many popular beginner apps block these securities.[](https://www.nerdwallet.com/investing/best/online-brokers-for-penny-stock-trading)
The best options for trading penny stocks depend on what you prioritize most:
Fidelity Investments
The Appeal: Widely considered the overall best choice for penny stocks. Unlike many traditional brokers that charge a per-trade fee for OTC securities, Fidelity offers $0 commission on online US-listed and OTC penny stock trades. It also provides great research tools and solid order execution.
Best for: Cost-conscious traders who want commission-free OTC access alongside robust institutional research.
Interactive Brokers (IBKR)
The Appeal: Known for deep market access and sophisticated tools (like Trader Workstation), IBKR supports global markets and a massive selection of OTC and low-priced stocks. Pricing is very low, though tiered vs. fixed pricing structures apply depending on your volume.
The Appeal: Offers full access to OTCBB and Pink Sheet securities through its standard platform. Schwab provides top-tier research, solid mobile apps, and integrated access to platforms like thinkorswim . Note that standard online OTC trades carry a flat fee (typically $6.95 per trade).
The Appeal: Features a user-friendly interface and the Power E*TRADE platform, which is great for technical analysis. Like Schwab, E*TRADE charges a flat $6.95 fee for OTC transactions.
Best for: Intermediate traders who value a clean user experience backed by strong educational and fundamental analysis.
Note on apps like Robinhood : While they let you buy low-priced stocks that are listed on major exchanges (like NASDAQ or NYSE), they do not support OTC markets where a vast majority of true penny stocks trade.
To help narrow down the best fit, tell me:
Are you planning to trade OTC/Pink Sheet stocks or only low-priced stocks on major exchanges (NYSE/NASDAQ)?
Do you prefer a mobile app or an advanced desktop platform for charting?
If you're looking for a brokerage platform to trade penny stocks in the U.S., I'd start with Fidelity, Charles Schwab, or Interactive Brokers. The best choice depends on whether you want low fees, access to over-the-counter (OTC) stocks, or advanced trading tools.
One important distinction: some penny stocks trade on Nasdaq or the NYSE, while others trade on OTC markets. A broker that supports exchange-listed stocks may not let you buy the OTC stocks you're interested in.
Best brokerage platforms for penny stocks in 2026
1. Fidelity
(Best overall)
Best for low costs and research
Fidelity offers $0 online commissions for eligible OTC stock trades and strong research tools, including information on trading volume and short interest. A good starting point for both newer and experienced traders.
If you're brand new: Fidelity is worth looking at because of its relatively simple app and $0 OTC commission structure. Penny stocks can be extremely volatile and illiquid, and OTC securities can have less disclosure than exchange-listed stocks.
If you tell me how much you're planning to invest (e.g. $100, $500, $1,000), I can also show you how to screen penny stocks for volume, catalysts, financials, and scam/pump-and-dump warning signs without picking a stock for you.
Its thinkorswim platform provides sophisticated charting, technical indicators, screeners, and customizable trading tools. A strong option if you plan to analyze and trade stocks actively.
Reported OTC commission: $6.95 per trade. Verify the current fee schedule and eligible securities.
Worth considering if you want professional-grade order management, detailed market data, and access to a broad range of securities. Its pricing structure can suit active traders, but commissions and market access vary by plan and security.
Webull supports more than 500 OTC securities, with $0 OTC commissions. However, availability is limited to supported symbols, and OTC trades have specific order and price restrictions.
Offers $0 commissions on eligible OTC stock trades and a relatively straightforward platform. Consider it if keeping trading costs low is your main priority.
Fees and available securities can change, so check each broker's current pricing and OTC eligibility rules before opening an account.
What to watch out for with penny stocks
Liquidity: Some stocks trade so infrequently that selling your shares at a reasonable price can be difficult.
Wide spreads: The gap between the buying and selling prices can eat into profits.
Fraud and volatility: Some thinly traded companies are vulnerable to pump-and-dump schemes.
Use limit orders: They let you specify the maximum price you will pay when buying, rather than accepting an unpredictable market price. They do not guarantee execution.
Let me narrow this down for you
The most important question is what kind of penny stocks you want to trade.
