CMC Markets Launches 24/5 US Share Trading and Fractional Investing for UK Clients
By Ali Paterson · 10 September 2026

Quick Summary
UK investors can now access 24/5 US share trading through the CMC Invest platform, allowing for round-the-clock responses to global market volatility. By combining extended hours with fractional investing and zero-commission trades, CMC Markets provides retail traders with institutional-grade flexibility to manage US equity portfolios at any time.
How Does CMC Markets Enable 24/5 US Share Trading?
24/5 US share trading is the cornerstone of this update, removing the traditional barriers of market opening and closing times. UK-based clients can now execute market orders and other order types during overnight sessions, ensuring they are never locked out of price movements triggered by after-hours earnings reports or international news. This continuous market access is designed to bridge the gap between the UK and US time zones, providing a seamless experience for active traders.
- Round-the-clock access to major US equities.
- Market order support during extended and overnight sessions.
- Real-time response capabilities for earnings announcements.
What are the Benefits of Fractional Investing for Retail Traders?
By integrating fractional investing, CMC Markets allows users to diversify high-priced stocks without requiring significant capital outlays. This feature enables investors to buy portions of shares, ensuring that portfolio allocation is based on a specific pound amount rather than share price. When paired with the 0% commission structure, it lowers the entry barrier for younger or more cautious investors looking to build a diversified US portfolio over time.
- Lower capital requirements for expensive blue-chip stocks.
- Flexible portfolio construction based on specific investment amounts.
- Cost-effective scaling with zero commission on trades.
How Does This Move Impact the UK Fintech Landscape?
This launch represents a strategic multi-asset shift for CMC Markets as it seeks to unify its trading and investing arms. By offering institutional-grade functionality to retail users, CMC is positioning itself against both traditional wealth managers and modern neo-brokers. The focus on proprietary technology and strategic partnerships ensures that the platform remains competitive in a market where instant market access and low costs are now the baseline expectations for consumers.
FF NEWS TAKE:
CMC Markets is clearly tired of playing second fiddle to the neo-broker crowd. By launching 24/5 US share trading, they are hitting a massive pain point for UK investors who have long felt the sting of time-zone lag. This isn't just a feature update; it's a bold land grab for the sophisticated retail segment. If CMC can maintain its 0% commission promise while offering this level of market liquidity, they may well redefine what a 'standard' brokerage account looks like in the UK.
