Bitcoin is trading above $73,000 Friday evening, and the derivatives data sitting behind that price tells a more cautious story than the spot number suggests. Across futures exchanges and options desks, traders have been stacking protection, pulling back call exposure, and watching a cluster of max pain levels that puts significant pressure right below current prices.
Key Takeaways:
- Bitcoin CME options open interest shows puts dominating since late 2025, with calls holding a 57% edge on Deribit in April 2026.
- Total $BTC options OI reached $30B+, while Binance leads futures at $9.31B and CME ranks second at $8.74B across 11 tracked exchanges.
- Max pain levels on Deribit, OKX, and Binance cluster near $70K to $72K ahead of the April 24, 2026, expiration with the heaviest notional value.
Futures Open Interest: Binance Leads, CME Close Behind
Total bitcoin futures open interest (OI) across major exchanges sits in the tens of billions, according to coinglass.com stats. Binance currently holds the top spot at 127.39K $BTC, roughly $9.31 billion, accounting for 16.86% of the tracked market. CME lands in second at 119.64K $BTC ($8.74B, 15.83%), followed by MEXC at 91.65K $BTC ($6.7B). Gate, Bybit, and OKX round out the next tier at $4.57 billion, $4.70 billion, and $3.23 billion, respectively.
Over the past 24 hours, most exchanges posted positive open interest changes. Gate led at +9.04%, Bybit came in at +7.84%, and Kucoin ticked up +7.44%. BingX was a notable outlier, showing a 4-hour change of -15.70%, suggesting some position unwinding on that platform. The broader trend, though, points upward, with OI recovering off the lows hit in January and February 2026.
Futures Open Interest in Context: Off the Peak, Rebuilding
The longer view on exchange bitcoin futures open interest shows just how much ground has been covered. From roughly $30 billion in mid-2024, total OI ran to nearly $100 billion by late 2025 when bitcoin hit all-time highs above $120K.
The subsequent drawdown pulled OI back hard, bottoming near $40 billion in early 2026, before the current rebuild toward the $45 billion to $50 billion range. Price and open interest are moving together again, which traders typically read as healthier positioning. Essentially, the market is reforming after the massive Oct. 10 liquidation event last year.
CME Options: A Shrinking Market With a Put Lean
CME bitcoin options open interest tells a story of contraction. The peak in late 2025 saw stacked weekly bars reach 70,000 contracts. By early 2026, that number fell sharply, dropping into the 10,000 to 15,000 contract range by February before a modest bounce in March and April. The current reading sits around 20,000 contracts for the most recent expiry period, a fraction of last year’s highs.
More telling is the composition. When stacked by position type, calls versus puts, the CME options market has shifted hard toward puts since October 2025. Put open interest in USD terms swelled to nearly $285 million in December 2025 and has remained elevated through April 2026, while call exposure has nearly evaporated, sitting close to zero in recent weeks. Traders on CME are buying protection. They are not pressing upside bets.
Options Market Breadth: Deribit Still Dominates
Across all exchanges, total bitcoin options open interest peaked near $30 billion in late 2025 and still hovers in that range today. On Deribit, the biggest bets are positioned around $120,000 by December 2026 and $80,000 by May 2026, with the $80,000 strike also seeing the heaviest single-day trading volume on OKX. Traders are clearly anchoring their targets well above current prices.
The broader options picture leans bullish for now. On Deribit, calls, meaning bets that bitcoin goes higher, outnumber puts, or bets on a price drop, at roughly 57% to 43%. Friday’s trading volume told the same story, with calls taking about 61% of activity versus 39% for puts.
Max Pain: Three Exchanges, One Clear Message
Max pain levels across Deribit, Binance, and OKX all cluster near $70,000 to $72,000, with meaningful notional value tied to the April 24, 2026, expiration. On Deribit, the April 24 expiry carries the highest notional bar, roughly $8 billion, with max pain sitting around $72,000. The June 26 expiration also shows elevated notional near $8 billion with max pain near $75,500 before curving down sharply toward year-end.
Binance’s max pain data shows near-term expirations, April 11 through April 13, priced around $71,000 to $72,000, while the April 24 contract, the heaviest by notional, anchors at approximately $71,500. OKX tracks similarly, with April 24 carrying the most weight and max pain oscillating between $70,000 and $75,500 in the near-to-mid term.
With bitcoin at $73,000 today and max pain concentrated just below at $70,000 to $72,000, options market mechanics alone create a headwind. Whether the spot market respects those levels is a different question, but the derivatives data makes the setup plain.
