BTC Options Flow Analysis — May 18, 2026

The flow validates my bearish bias. Institutional selling pressure on June 26 was massive. The rebound to $80,000 possible but a difficult level to cross, see Open Interest.

Daily volume — strong signal on June 26

Today's puts/calls ratio on the expiry of June 26 is 2. 8:1 — 1,820 puts bought against 650 calls. This is the most marked imbalance of all the deadlines. Someone is massively protecting themselves or expressing a strong bearish belief in June. To watch out for: May 29 concentrates the largest overall volume (2,420 contracts) with a relatively balanced distribution — this is the short-term expiry pivot.

OI by expiration — June 26th dominates

June 26 represents ~120,000 open contracts, the largest OI of all deadlines. Crucial detail: a significant portion are ITM calls — these are positions bought when BTC was above $80,000. These holders are currently under water. Their behavior (holding, driving, or cutting) will be the main driver of the market by the end of June.

OI by strike — BTC stuck between two walls

The graph is very clear:

Wall of calls at $80,000 → 7,200 contracts. Major resistance. The market makers shorted on these calls sell the spot to cover themselves → natural ceiling.
Wall of bets at $75,000 → 6,000 contracts. Bearish attraction zone + Max Pain.
Max Pain $75,000 → $3,345 under the current spot. Gravity is pulling downwards.

BTC at $78,345 is in between: under the call ceiling ($80k) and above the draw zone for puts ($75k).
