[Bitcoin options daily] Open interest falls to $32.09 billion; $81,000 calls lead volume

Bitcoin options open interest fell 6.70% from the previous day to $32.09 billion. Calls accounted for the larger share of both outstanding positions and daily trading, with the $81,000 call leading both rankings.

Call options retained their lead as the overall value of outstanding Bitcoin options declined. Their larger share of both open interest and trading volume showed a similar tilt across accumulated positions and daily activity.

As of November 7 at 12:05 UTC, Bitcoin options open interest stood at $32.09 billion, down from $34.39 billion the previous day. Trading volume totaled approximately $3.76 billion.

Calls represented 57.12% of open interest, while puts accounted for 42.88%. In 24-hour trading volume, calls made up 61.68% and puts 38.32%.

The call-heavy open interest mix indicated that more outstanding exposure sat in calls, while daily trading showed an even larger call share. However, the decline in total open interest limited the evidence for strengthening bullish positioning through an expansion in outstanding contracts.

The contracts with the highest open interest were, in order, the $81,000 call expiring November 13, 2026; the $80,000 call expiring December 25, 2026; and the $100,000 call expiring December 25, 2026. All were on Deribit.

The leading contracts by 24-hour trading volume were the $81,000 call expiring November 13, 2026; the $84,000 call expiring November 13, 2026; and the $95,000 call expiring November 27, 2026. All were on Deribit.

[Editor's note] Options are derivatives used to take leveraged exposure to price movements or hedge existing positions. A call gives its holder the right to buy the underlying asset at a predetermined price, while a put gives the right to sell. Open interest measures outstanding contracts and indicates the accumulated size of positions.

Call and put shares, alongside changes in open interest and volume, help distinguish accumulated positioning from shorter-term trading activity. Rising open interest indicates growth in outstanding positions. A larger call share alone does not establish a bullish outlook, as options can also form part of hedges or strategies involving multiple contracts.
