Key Highlights
- Bitcoin enters May-end with nearly $15 billion in combined Deribit options and CME Bitcoin futures open interest.
- Deribit’s May 29 BTC options expiry carries about $6.25 billion in open interest.
- CME standard Bitcoin futures OI stood at 23,000 contracts, equal to 115,000 BTC, as of May 19.
Bitcoin is heading into the end of May with one of the largest derivatives setups of the month, as nearly $15 billion in combined Deribit options and CME Bitcoin futures open interest sits around the market.
The pressure point is the May 29 BTC options expiry on Deribit, where roughly $6.25 billion in contracts are set to roll off. The expiry is centered around the $75,000 max pain level, with heavy call positioning near the $80,000–$82,000 range, keeping Bitcoin pinned inside a narrow but highly leveraged zone.
The CME side adds another major layer. According to the latest CFTC futures-only report, CME standard Bitcoin futures open interest stood at 23,000 contracts as of May 19. Each CME Bitcoin futures contract represents 5 BTC, putting total exposure at 115,000 BTC. At Bitcoin’s current price near $75,144, that equals roughly $8.64 billion in notional open interest.
CME Micro Bitcoin futures add a smaller but still relevant layer. CFTC data shows 17,896 micro contracts in open interest as of May 19. With each micro contract representing 0.1 BTC, that adds about 1,790 BTC, or roughly $134 million in notional exposure at current prices.
Bitcoin’s May-End OI Setup
| Venue | Product | OI | Approx. Notional |
|---|---|---|---|
| Deribit | May 29 BTC options expiry | 80,535 contracts | $6.25B |
| CME | Standard BTC futures | 23,000 contracts / 115,000 BTC | $8.64B |
| CME | Micro BTC futures | 17,896 contracts / ~1,790 BTC | $134M |
| Combined | Deribit + CME | — | ~$15.02B |
The combined figure does not mean all positions are directionally long or short. Options open interest includes both calls and puts, while futures OI reflects open contracts on both sides of the trade. But the size matters because large expiries can force dealers, market makers, and leveraged traders to adjust hedges as Bitcoin moves closer to key strike zones.
For now, the main battle is simple: $75,000 remains the magnet, while $80,000 remains the breakout wall. A sustained move above the call-heavy zone could force more upside hedging, while failure to clear it may keep Bitcoin trapped around max pain into expiry.
That makes May-end less about spot price alone and more about positioning. With Deribit options, CME futures, and micro futures together carrying nearly $15 billion in exposure, Bitcoin’s next major move may depend on how quickly traders unwind, roll, or defend their positions after the May 29 expiry.
