Bitcoin derivatives markets are sending mixed signals as of Saturday, with open interest climbing back toward $30 billion while options and futures traders maintain positions across major exchanges. The price of bitcoin is steady at $78,418, hovering near key max pain levels ahead of the May 3 expiry.
Futures Open Interest: Binance Leads, CME Stands Out
According to Coinglass, total BTC futures open interest across exchanges is led by Binance with 134,620 BTC ($10.55B), followed by CME with 117,320 BTC ($9.20B). Gate, MEXC, and Bybit hold 68,860 BTC, 78,430 BTC, and 59,890 BTC respectively. CME's 24-hour OI change of +6.16% stands out as most other exchanges reported mild declines, with the notable exception of BingX which plummeted 54.60%. KuCoin bucked the trend with a 4.32% increase.
Options Market: Calls Dominate Open Interest, Puts Lead Volume
On the options side, calls maintain an edge over puts in open interest. Total call OI stands at 241,222.88 BTC versus 169,755.09 BTC for puts, yielding a call/put ratio of approximately 58.69% vs 41.31%. However, 24-hour volume tells a different story: puts account for 53.65% of trading activity, indicating short-term hedging from traders.
The most actively held single option contract on Deribit is the May 29 call at the $80,000 strike, with 7,493.7 BTC in open positions. Close behind is the December 2026 call targeting $120,000 with 6,600 BTC OI, followed by a June 2026 $90,000 call with 6,362.7 BTC. On the bearish side, the largest put is a December 2026 $60,000 strike with 5,298.9 BTC OI.
Max Pain Levels Vary by Exchange
As the May 3 expiry approaches, max pain levels diverge across platforms. Deribit places current max pain near $78,000, essentially at parity with bitcoin's $78,418 price. Binance's May 29 expiry shows max pain near $75,000, while OKX's May 3 expiry is strikingly bearish at $65,000. Longer-dated contracts on Deribit show a descending curve toward $69,000 for March 2027 expiry, though notional value spikes for the June 2026 expiry at around $9 billion.
CME options open interest, stacked by expiry, shows contracts maturing in one to two months dominating the structure. CryptoQuant data reveals a sharp contraction from the November 2025 highs when total CME options OI approached 70,000 contracts; current levels sit between 8,000 and 14,000 per expiry cycle. The put/call distribution on CME shows puts consistently outperforming calls in USD terms through February and March 2026 before flattening, with call interest rebuilding through April.
Whale Movement and ETF Inflows
In a separate development, a newly created wallet withdrew 1,051 BTC ($82.35 million) from Binance in a single transaction. At the same time, U.S. spot Bitcoin ETFs recorded net inflows of $630 million, signaling continued institutional appetite for digital assets.
With bitcoin trading at $78,418, it sits above short-term max pain for Binance and OKX but right on Deribit's level. Options dealers managing exposure near expiry could act as a silent force shaping price action through the weekend. The contradictory signals between bullish options OI and bearish short-term volume, combined with whale accumulation and ETF inflows, suggest the market may be building for a decisive move.
