Best OTC Stock Brokers: Where to Trade Penny Stocks Like AITX
Finding the right platform to trade over-the-counter (OTC) stocks like Artificial Intelligence Technology Solutions Inc. (AITX) can be the difference between a seamless investment experience and one riddled with hidden fees and execution delays. As the AI sector continues to capture investor attention, many are looking for reliable gateways into the world of "Pink Sheets" and penny stocks.
While most major brokerages have moved to $0 commissions for exchange-listed stocks (like those on the Nasdaq or NYSE), the rules for OTC securities are different. In 2026, several key players stand out for their accessibility, fee structures, and specialized tools for high-growth tech investments.
Top Brokerage Picks for AITX and OTC Trading
Selecting a broker for AITX requires looking beyond the flashy interface. You need a firm that prioritizes order execution quality and provides transparent access to the OTCPK (Pink Open Market) tier where AITX resides.
1. Fidelity Investments: The Gold Standard for OTC
Fidelity remains a top recommendation for retail investors targeting AITX. They are one of the few major brokers that offer $0 commissions on domestic OTC stocks without tacking on the "penny stock surcharges" common elsewhere.
Why it works: Fidelity does not accept Payment for Order Flow (PFOF) on equity trades, which often results in better price improvement for the buyer.
AITX Accessibility: Full access to AITX with real-time quotes (once a free agreement is signed).
2. Charles Schwab: Robust Research and Reliability
Following its full integration with TD Ameritrade, Schwab has become a powerhouse for OTC traders. While they do charge a small flat fee for OTC transactions, their platform stability and research tools are world-class.
Fee Structure: Expect a standard flat fee (typically $6.95) per executed trade for OTC securities.
Pro Tip: Use the thinkorswim platform (available to Schwab clients) for advanced technical analysis on AITX's price action and volume trends.
3. Interactive Brokers (IBKR): The Professional Choice
For active traders who move high volumes of shares, IBKR is often the most cost-effective. They provide deep market access and institutional-grade tools that help navigate the volatile swings characteristic of AI penny stocks.
Fee Structure: They typically use a per-share pricing model (e.g., $0.005 per share), which is ideal for small positions but can scale up for larger trades.
Transparency: IBKR provides detailed information on the "Bid/Ask" spread, which is crucial for illiquid OTC stocks.

Essential Requirements for Trading OTC Stocks
Before you can place your first order for AITX, you may need to navigate a few "compliance" steps required by these brokerages. These are designed to ensure you understand the speculative nature of low-priced securities.
Penny Stock Disclosures: Most brokers require you to read and "sign" an electronic disclosure agreement. This simply confirms you are aware that OTC stocks carry higher volatility.
Settled Funds: Many platforms will not allow you to buy AITX using "instant" deposits or margin. You must wait for your bank transfer to fully clear (usually 1–3 business days) before the funds are considered Settled Cash.
Limit Orders Only: Due to the wide spreads in the OTC market, many brokers will only allow Limit Orders for stocks priced under a certain threshold. This is a protective measure to prevent you from accidentally buying at a price significantly higher than the current market rate.
How to Screen for the Best AI Penny Stocks
While AITX is a popular choice due to its presence in the robotic security space, a successful portfolio often involves monitoring the broader "Physical AI" sector. When using your broker's screening tools, look for these specific indicators:
Reporting Status: Prioritize "SEC Reporting" companies over "No Information" companies. AITX maintains transparent filings, which is a significant green flag in the penny stock world.
Volume Trends: High relative volume often precedes a major move. Look for stocks where the daily trading volume is increasing consistently.
Share Structure: Check the "Authorized" vs. "Outstanding" share count. A company with a stable share structure is generally more attractive than one undergoing heavy dilution.
Final Decision: Which Broker Should You Choose?
If your goal is to buy and hold AITX with the lowest possible overhead, Fidelity is the clear winner due to its $0 fee structure. However, if you require advanced charting tools to time your entries and exits with precision, Charles Schwab’s thinkorswim is the industry standard.
Regardless of the platform you choose, remember that the OTC market requires a disciplined approach. Start with a position size that fits your risk tolerance and always keep an eye on the company's official filings to stay ahead of the curve.
