Apple and Amazon released their latest quarterly earnings after the U.S. market closed on July 30 (U.S. time)—Apple reporting fiscal third-quarter results and Amazon announcing second-quarter earnings. Instead of waiting for the next trading session, global investors responded immediately through 24-hour markets, where price formation began almost as soon as the results were released.
According to trading data released by global digital asset platform OKX, approximately 83% of the combined trading volume in Apple (AAPL) and Amazon (AMZN) futures occurred outside regular U.S. market hours (9:30 a.m.–4:00 p.m. ET). On their earnings day, Apple futures volume increased 380.9% from the previous day and 229.9% above the previous seven-day average, while Amazon futures volume rose 331.6% from the previous day.
The significance of these figures extends beyond unusually high trading activity. They suggest that the market's first price reaction to major corporate earnings is no longer waiting for Wall Street to open.
The Rules of Capital Markets Are Changing in the AI Era
For decades, global capital markets operated on a simple principle: prices were discovered when exchanges opened. Even if companies released earnings after the closing bell, investors generally had to wait until the next trading session before the market could fully incorporate the new information.
That model is beginning to change. The expansion of 24-hour trading platforms and digital asset markets means that price formation increasingly begins when information is released, not when exchanges open.
AI-powered trading systems and algorithmic investors can analyze earnings reports, guidance, financial statements and conference calls within seconds and execute trades almost immediately. In an environment where machines react faster than human investors, the opening hours of traditional exchanges are becoming less important than the timing of information itself.
The implications extend beyond U.S. markets. Korean investors closely follow earnings from Apple, NVIDIA, Microsoft, Amazon and other AI leaders, yet most of these announcements are released during the Korean early morning. As always-on global trading expands, prices established before Wall Street opens are likely to play a greater role in shaping investor sentiment and trading strategies worldwide.
The trend may also influence future discussions around extended exchange trading hours, tokenized securities and digital asset-based financial products in markets such as South Korea.
The broader message behind the OKX data is not simply that trading volumes are increasing. It is that the process of price formation itself is evolving. For more than a century, the opening bell marked the beginning of price discovery. Today, as AI and 24-hour trading infrastructure converge, markets are beginning to price information the moment it becomes available.
This represents more than longer trading hours. It signals a structural shift in global capital markets—from a system centered on exchange operating hours to one driven by the continuous flow of information. As AI adoption accelerates and always-on financial infrastructure expands, that transition is likely to become one of the defining characteristics of next-generation capital markets.
