Deribit is staring down a massive Bitcoin options expiry this Friday, with roughly 80,535 BTC contracts — about $6.25 billion notional — set to settle on May 29, 2026. That's nearly a quarter of the exchange's total open interest concentrated in a single front-month expiration, and the strikes that matter most are forming a tight band between $75,000 and $80,000.
The $75K–$80K corridor
Open interest data shows the largest put strike sits near $75,000, while the heaviest call interest clusters around $80,000. The two price levels effectively bookend where dealers have the most exposure. When so much notional value is stacked at specific strikes, the market tends to pin the spot price somewhere in between as hedgers adjust positions.
Pin risk in play
The mechanics of options hedging create what traders call pin risk. Dealers who are short calls often sell spot when the price pushes toward those call walls, capping upside. Conversely, dealers short puts tend to buy spot when the price slides toward the put floor. That push-and-pull can lock Bitcoin into a range during the final hours before expiry — and Friday's setup has both walls well defined.
What traders are watching
One standout trade: the BTC 29MAY26 $82,000 call was the most active single contract on May 21, with about 1,600 contracts changing hands — roughly $126 million notional. That strike sits just above the main call wall, suggesting some traders are betting on a late-week breakout. But with 22.4% of all open interest expiring Friday, the gravitational pull of the $75K–$80K zone is strong.
Friday's 8:00 AM UTC settlement will show whether the corridor holds or if momentum breaks one side. Either way, the next few days are likely to see positioning tighten as the clock runs down.
