Hey, it’s Marc,

What happened

In February, CME Group said what traders have been begging for: 24/7 crypto futures and options, live on Globex starting May 29. Continuous trading, one two-hour maintenance window per week, done.

Why now: The trigger is volume. Bitcoin and Ether ETFs brought in billions of dollars and a big problem: traders needed to hedge over the weekend, but CME was closed. They sat exposed to price swings with zero cover. That problem dies on May 29.”

The numbers tell the story: In 2025, CME processed a record $3T in notional crypto volume. This year, Average Daily Volume (ADV) surged 46% year-over-year to 407,200 contracts. Large open interest holders hit a record 1,039.
