Bitcoin derivatives markets have swelled to nearly $100 billion in combined exposure, with futures holding $56.3 billion in open interest and options at approximately $42 billion as bitcoin trades near $81,273.
The positioning reveals a pronounced bullish tilt in the options market. Call options control 60.74% of bitcoin options open interest, representing 311,306.86 BTC, while put options account for 39.26%, totaling 201,232.2 BTC. The 24-hour volume shows calls at 59.01% versus puts at 40.99%, maintaining the call-heavy lean.
Futures Market Leadership
Binance leads the futures market with $11.77 billion in open interest across 144,810 BTC, representing 20.89% of the market. CME follows with $8.74 billion and 107,450 BTC at 15.5% market share. Bybit and Gate each carry approximately $5.36 billion, while MEXC holds $4.78 billion, Hyperliquid $3.47 billion, and OKX $3.12 billion.
Aggregate futures open interest has climbed from below $50 billion in August toward the mid-$50 billion range as bitcoin recovered toward $80,000. Short-term expansion remains modest, with most venues showing one-hour changes of less than one percent.
Options Concentration
The largest options positions cluster around September strikes between $70,000 and $100,000. On Deribit, the Sept. 25 $70,000 call holds 10,916.3 BTC in open interest, followed by the $85,000 call at 10,202.3 BTC and the $90,000 call at 9,544.1 BTC. Additional substantial positions include the $100,000 call at 7,193.4 BTC and the $82,000 and $80,000 calls at 6,922.5 BTC and 6,489.7 BTC respectively.
Trading volume concentrates near bitcoin's current price levels. The Sept. 25 $85,000 call leads 24-hour volume at 2,270.9 BTC, followed by the $82,000 call at 1,251.1 BTC.
Max Pain Below Spot Price
Max pain levels for the September 25 expiration sit notably below bitcoin's current price across major venues. Deribit shows max pain near $72,000, Binance around $76,000, and OKX near $75,000. With bitcoin at approximately $81,273, all three readings are roughly $5,000 to $9,000 below the current level.
Max pain represents the strike where the greatest notional value of outstanding options would expire worthless at expiration. While it serves as a positioning metric rather than a price prediction, traders monitor it for insights into potential dynamics as settlement approaches.
Bitcoin has traded between $75,038 and $81,710 during the week, with substantial call exposure stacked at $82,000, $85,000, $90,000, and $100,000 strikes ahead of the September 25 expiration.
