Bitcoin CME futures traded on the Chicago Mercantile Exchange (CME) are financial products that allow investors to invest in Bitcoin prices without actually owning Bitcoin. This derivative product, which debuted in December 2017, is now considered one of the most representative institutional investment products in the Bitcoin market.
Unlike spot Bitcoin trading on cryptocurrency exchanges, CME futures allow traders to enter long or short positions using leverage. These trades are settled in cash, and traders profit from the difference between the entry price and settlement price rather than actual Bitcoin.
CME gaps occur due to trading time differences between the Bitcoin futures market and the real-time spot market on cryptocurrency exchanges. The Chicago Mercantile Exchange closes at 4:00 PM on Friday and opens at 5:00 PM on Sunday, making significant price movements possible during this period. When the exchange reopens, it may start at a different price than Friday’s closing price, creating a “gap” on the chart.
This difference is significant because Bitcoin generally tends to “fill” these gaps. That is, prices typically maintain their trend before revisiting the gap level.
The Chicago Mercantile Exchange is one of the world’s largest and most prestigious derivatives exchanges. It provides futures and options trading services for commodities, stocks, cryptocurrencies, and other assets across various asset classes. In December 2017, the CME Group introduced Bitcoin futures products (BTC), enabling both institutional and individual investors to invest in cryptocurrency prices without directly owning the assets.
CME’s Bitcoin futures hold an important position in the digital asset market, with daily trading volumes reaching tens of billions of dollars. These trades are settled in cash, and at settlement, traders receive profits based on price differences in U.S. dollars rather than actual Bitcoin.

Bitcoin can be traded in the following three ways:
Spot Trading: Real-time Bitcoin trading
Perpetual Swaps (Perps) on Cryptocurrency Exchanges: Margin contracts with no expiration date
CME Bitcoin Futures: High-grade institutional contracts with fixed expiration dates
Unlike cryptocurrency exchanges, CME Bitcoin futures operate only during designated trading hours, similar to traditional financial markets. Below is the official schedule based on Central Time (CT):
Market Open: Sunday 5:00 PM Central Standard Time
Trading is suspended daily from 4:00 PM to 5:00 PM Central Standard Time, Monday through Friday.
Weekend Closure: Friday 4:00 PM Central Time
This means CME Bitcoin futures are closed for 60 minutes each weekday and unavailable from Friday afternoon until Sunday evening.
Since cryptocurrencies trade 24/7 without holidays, prices are likely to fluctuate significantly during weekends when CME is closed. When the Chicago Mercantile Exchange market reopens at 5:00 PM Central Standard Time on Sunday, trading begins at the latest market price, which may be higher or lower than Friday’s closing price.
For this reason, “gaps” appear on CME Bitcoin futures charts. Since there is no closing price information when the exchange is closed, price movements are displayed as blank spaces. These gaps are commonly referred to by traders as CME gaps—the empty spaces between price movements.
To understand more easily, you can think of CME gaps as broken sections on a candlestick chart.
Price gaps on the Chicago Mercantile Exchange are considered one of the important phenomena in Bitcoin trading. Many investors believe that Bitcoin prices tend to fill these gaps. This means that prices eventually return to the gap level and then continue their trend. Due to this belief, CME gaps are utilized as important price levels in trading strategies.
The CME gap filling theory is one of the hot topics of debate in the Bitcoin market. This theory argues that when gaps occur on CME Bitcoin futures charts, Bitcoin is likely to return to that price level in the future.
For example, in early 2024, a gap between $78,000 and $80,700 occurred in the CME futures market when the cryptocurrency market experienced rapid price volatility. Afterward, prices continued to trade above this range. However, this gap was not filled until approximately four months later, starting in early March 2025.
Traders have noted that over time, many CME Bitcoin futures gaps eventually get filled. Estimates suggest that approximately 70-80% of these gaps are filled as Bitcoin prices fluctuate, with some cases taking days, weeks, or even months. Some gaps are filled quickly by traders, while others may remain open for a long time before Bitcoin returns to that level.
An important finding is that larger gaps are more likely to be filled than smaller ones. Moreover, Bitcoin exhibits high price volatility, often rising or falling significantly during weekends. In such cases, gaps are often eventually filled by subsequent market movements. On the other hand, small gaps between $100 and $500 are sometimes overlooked by traders.
The narrowing of Bitcoin futures price gaps results from a combination of various factors, including market efficiency, trader behavior, institutional investor activity, and liquidity flows. When CME markets are not operating during weekends, Bitcoin continues to trade on spot exchanges, creating price differences that reduce price efficiency. When trading resumes, these differences are frequently adjusted as traders use arbitrage to restore liquidity and align futures prices with the spot market.
Furthermore, most traders expect these gaps to narrow. By doing so, they place orders that push prices up by the gap amount, creating a self-fulfilling prophecy. Ultimately, prices return to the gap level. Institutional investors who primarily handle CME trading also help fill these gaps by adjusting their positions to diversify such risks. Moreover, these stages attract order flow and liquidity, creating incentives for price movements and increasing the likelihood that gaps will eventually disappear.
