<a href="https://tech-oracle.com/btc-usd/">Bitcoin</a>’s famous CME gaps are about to disappear, though three remain unresolvedMarkets

What to know:

  • From Friday, CME Bitcoin futures and options now trade 24/7 on Globex, ending the traditional Friday-to-Sunday market closure that created the widely watched “CME gap.”
  • Despite the structural shift, liquidity remains concentrated in ETF options and offshore perpetuals, with IBIT options open interest far exceeding CME crypto options markets.

CME Group is now offering round-the-clock trading of Bitcoin futures and options. Starting Friday, these contracts will be available 24/7 on Globex, CME’s electronic trading platform, with a brief one-hour maintenance break every Sunday between 10 PM and 11 PM UTC.

Although trades made on the weekend will continue to be processed the following business day, this change is important because the historical gap in trading that occurred over weekends has essentially been eliminated.

For a long time, the way bitcoin traded between the end of the week (Friday close) and the start of the next (Sunday reopen) caused a predictable problem. Traders often took advantage of price differences between the CME (Chicago Mercantile Exchange) and the broader bitcoin market, because CME has limited trading hours while bitcoin trades 24/7. Because there’s less trading volume on weekends, these price gaps were often amplified, becoming both a signal for traders and a way to speculate on price movements.

As a researcher, I consistently observed a predictable pattern: volatility would jump significantly around 11 PM UTC on Sunday evenings. This happened when futures markets reopened and adjusted to the price changes that occurred over the weekend. Those weekend price movements were usually small, with low trading volume – essentially, a lot of random fluctuation. Because so few people were trading, even small orders could cause noticeable price swings, but these often reversed quickly once larger institutional traders became active late Sunday.

Now that the CME has scheduled its maintenance for Sunday from 10PM to 11PM UTC, expect similar conditions to previous maintenance periods. Trading activity will likely decrease as Globex closes, and when trading resumes at 11PM, there could be some initial price swings as the market stabilizes. It’s important to keep an eye on this situation in the coming weeks.

That period is mostly behind us now. By making futures trading match Bitcoin’s always-on market, CME is lowering the extra costs associated with weekend trading and helping institutions better protect their investments. Fund managers, hedge funds, and companies can now adjust their positions at any time, instead of having to wait until markets open again.

Despite the growth of Bitcoin futures on the Chicago Mercantile Exchange (CME), the majority of trading activity still happens elsewhere. According to Cole Kennelly, CEO of Volmex Labs, options for BlackRock’s IBIT ETF currently have around $27 to $30 billion in open interest – significantly more than the roughly $800 to $900 million for CME Bitcoin futures options. This difference explains why the BVIV-US Index (BVUS), which is based on the larger IBIT options market, is becoming the go-to benchmark for how institutions measure Bitcoin’s volatility.

Currently, offshore perpetual futures and ETF options are expected to remain the most popular choices. However, CME’s move to offer round-the-clock trading eliminates a major obstacle for wider adoption.

Okay, so as a crypto investor, I’ve been watching these CME gaps – they’re like price levels where trading didn’t fully happen, and the market often tries to fill them. Right now, there are three of them from this year. Two are above Bitcoin’s current price of around $73,000 – one near $80,000 from late January and another around $78,500. The other gap is below the current price, sitting just under $70,000. It’ll be interesting to see if Bitcoin revisits these levels and ‘fills’ those gaps.
