Short Bitcoin Positions Rise at CME as Institutional Activity Grows on Coinbase Prime
Key Facts
Open interest stood at 20,791 contracts on the same date. The figures put aggregate positions in a close range, contrary to an earlier draft’s claim of a much larger gap between shorts and longs. Among non-commercial traders, net long positions were positive, with 16,980 long contracts against 14,260 short contracts. This weekly snapshot shows a different distribution between the overall market and the non-commercial category; on its own, it does not establish a unified institutional trend.
On a weekly basis, open interest fell by 249 contracts between October 20 and 27. Over the same period, non-commercial traders’ long positions increased by 18 contracts, while their short positions fell by 284 contracts. That means the change in the non-commercial category came from a contraction in short positions and a limited increase in longs, not a jump in total positions. This change remains part of the standard-contract data covered by the committee’s report. Coinbase Prime trading volumes and the price-discount indicator refer to two later days, so they are readings from separate dates from the position data.
In the smaller futures market, total short positions in CME Micro Bitcoin contracts reached about 29,135 contracts on October 27, against 25,067 long contracts. Within the non-commercial category, short positions totaled 23,838 contracts, compared with 19,562 long contracts. These contracts present a different picture from standard contracts, with shorts exceeding longs both overall and among non-commercial traders. Their data are classified separately from standard-contract figures and should not be combined with them as if they were one type of contract. This divergence reflects differences in position distribution by product and category, without identifying the motives behind individual trades.
In spot trading activity through Coinbase Prime, volume reached 9,933.73 bitcoin on October 29, compared with 5,150.06 bitcoin the previous day. EconoTimes estimated 24-hour dollar-denominated trading volume at about $368.10 million. Prime figures include both buy and sell transactions, so the increase in volume does not show whether clients bought more bitcoin than they sold. This reading distinguishes rising activity from the direction of net flows, and cannot on its own be considered evidence of an institutional bullish or bearish bet. Prime data also refer to October 29, after the date of the Commodity Futures Trading Commission’s weekly position snapshot.
The Coinbase Premium Index remained negative on October 30, at -0.18% after -0.27% on October 29, according to CryptoQuant data cited by EconoTimes. The index compares the price of the BTC/USD pair on Coinbase with the price of BTC/USDT on Binance, showing the difference between the two platforms’ prices under this methodology. Although the reading improved from the previous day, it remained below zero on both dates. The index alone does not establish the direction of Coinbase Prime trading, and it should not be combined with trading volume to show that institutions were net sellers. Position, trading and premium data remain separate indicators, each with its own date and measurement basis.
On the company’s broader performance, Coinbase said on October 29 that net income reached $719 million in the third quarter of 2026, while adjusted net income was $78 million. The company’s share of cryptocurrency trading volume rose from 9.1% in the first quarter to 10.3% in the second quarter, then to 10.7% in the third quarter. Coinbase attributed its spot trading share gains to global demand for stablecoins and said derivatives share growth was supported by momentum in its products. It also said cryptocurrency derivatives trading volume recorded a compound annual growth rate of 179% in the two years preceding the third quarter. These results provide context for the company’s activity, but do not establish the direction of Prime transactions on any particular day.
In October, the integration of the INTX and Deribit platforms was completed, and Coinbase said it expected some short-term volatility in trading volumes as participants adjusted to the combined platform. In the broader market, Bitcoin closed at $77,368.77 on October 30, compared with $77,991.89 the previous day, according to EL7 data. Coinbase shares closed at $143.54, against $160.59 on October 29, while CME shares closed at about $303.14. These closing prices describe asset performance in the market over the period, but do not establish the cause of changes in positions or traders’ motives. The Commodity Futures Trading Commission report shows open positions through October 27, with a comparison against the week ended October 20.
