A World Without Market Closes

This article draws on a LinkedIn Live conversation with Mike Cahill (CEO of Douro Labs and Contributor to Pyth Network), hosted by Anthony J. Day. The discussion explored what is driving the shift toward extended and 24/7 trading, how market structure may evolve, and the data and operational infrastructure required when markets no longer follow a simple opening and closing bell.

Building the Infrastructure for Always-On Finance

For most of modern financial history, trading hours created a clear rhythm. Markets opened, prices formed, trading stopped, and participants had time to reconcile positions before the next session.

That rhythm is changing.

Trading increasingly continues outside traditional exchange hours. Investors in one region want access to assets listed in another. Venues want to offer more products for longer. Tokenized assets and blockchain-enabled markets operate across time zones by design. Digital platforms have also made it possible to create financial products that remain available through nights, weekends, and holidays.

The push toward extended trading hours comes from all of these forces. Together, they point to a broader change: financial markets are becoming global, software-driven systems that operate across a continuous cycle.

Why markets are extending their hours

Global investor demand is one of the clearest drivers.

An investor in Asia may need to manage exposure to US equities during local business hours. A European institution may want to respond to events in another region before the underlying exchange opens. The demand for access exists whenever people, businesses, and markets are active.

Competition between venues is another factor. Exchanges and trading platforms are looking for ways to attract volume, support new products, and differentiate themselves. Longer hours allow venues to serve customers who were previously forced to wait for the next session.

Tokenization adds another layer. Once an asset can be represented and transferred through programmable infrastructure, it becomes easier to make that asset available across borders and outside the operating hours of its original venue.

However, tokenization alone does not create a functioning market. A tokenized asset still needs credible pricing, liquidity, operational support, and clear rules for how trading is handled when the underlying market is closed.

This points to a broader shift toward extended trading. Markets are moving beyond being defined by the operating hours of a particular exchange. Instead, they are becoming more continuous, interconnected, and accessible through multiple types of venues.

What changes when markets stay open?

Extended trading will create meaningful benefits for investors, issuers, and venues.

Investors gain more flexibility. Issuers and platforms can reach users in more time zones. Venues can support new products that would be difficult to operate within a traditional session. Global markets can respond more quickly to news and changing conditions.

The transition also introduces challenges.

Liquidity will be distributed across more hours and more venues. Some periods will be deep and active. Others will be thinner, with wider spreads and more limited participation. Price discovery may become more continuous, while the quality of that discovery varies throughout the day.

Volatility could also behave differently. A news event that previously waited for the next market open may now be reflected immediately in an overnight session. That can reduce opening gaps, while creating sharper moves during periods when fewer participants are active.

Market fragmentation is another important consideration. As more venues offer extended trading, the industry will need to understand how prices relate across platforms, how liquidity moves between them, and which prices should be used for risk management, margin, and product valuation.

The winners will be the participants that can provide broader access without allowing market quality to deteriorate.
