Bruce ATS Sees 66% Monthly Growth in Overnight U.S. Trading

Bruce Markets reported that its overnight U.S. equities venue, Bruce ATS, has recorded sustained growth since launch, with monthly average traded notional reaching $502 million in March 2026. According to Bruce Markets, traded notional on the platform has grown at an average monthly rate of 66% since October 2025, reflecting rising participation in overnight trading sessions and increased activity in after-hours markets.

Overnight Trading Expansion

Bruce Markets said total overnight trading volume across the market has nearly doubled over the past year, driven by global news flow and international investor participation. The platform reported that average volume per session exceeded 10 million shares in March 2026, while the number of symbols traded rose to an average of 1,837 per session. Over the full month, a total of 4,451 unique symbols were traded, indicating broader coverage across the equity market.

Participation has been supported by international investors, including activity from markets such as South Korea, alongside a shift toward continuous trading in response to an always-active news cycle. This expansion suggests that overnight trading is moving beyond a narrow set of highly liquid stocks into a wider range of securities.

Liquidity Development and Multi-Venue Ecosystem

The increase in traded notional and volume points to improving liquidity conditions on Bruce ATS. Bruce Markets said the platform has nearly doubled its share of overnight trading activity since the start of 2026, indicating that competition between venues is beginning to shape this segment of the market.

Jason Wallach, Chief Executive Officer of Bruce Markets, commented: “Over the past year, the overnight session has evolved into a meaningful extension of the trading day. Market participation is expanding globally, liquidity is deepening and demand for institutional-grade infrastructure continues to grow. This momentum reflects both the strength of the overnight market and the growing importance of a multi-venue ecosystem to enhance execution quality and resilience.”

As alternative trading systems and exchanges explore overnight models, liquidity is likely to be distributed across multiple venues. The development of a multi-venue ecosystem introduces both opportunities and challenges—competition can improve pricing and execution quality, but can also fragment liquidity, requiring participants to use routing strategies that aggregate multiple sources.

Market Structure and Extended Trading Hours

The rise of overnight trading reflects a broader shift in market structure toward longer or continuous trading hours. Alternative trading systems like Bruce ATS are positioned to capture demand for extended trading by offering after-hours access that connects with pre-market activity.

Bruce ATS operates from 8:00 PM to 4:00 AM Eastern Time, a period that overlaps with trading activity in Asia and early European markets. This positioning allows investors to react to earnings releases, macroeconomic data, and geopolitical events as they occur, rather than waiting for the next regular session. However, overnight trading also presents challenges, including lower liquidity compared with peak hours and potential price volatility in less active periods.

Bruce Markets said its growth reflects increasing demand for overnight access and suggests that the segment is becoming a more established component of equity market activity. The extent to which this trend continues will depend on participation levels, infrastructure development, and how regulators and exchanges approach extended trading models.
