Options Open Interest Shifts Decisively to Longer-Dated Strikes

For most of bitcoin's history as a listed derivative, open interest clustered in the nearest weekly expiry. That is no longer true. Contracts expiring more than six months out now account for the largest single share of outstanding notional on the dominant offshore venue, and a comparable shift is visible in regulated US listings.

Long-dated positioning is a different animal from weekly speculation. It ties up more margin, is far harder to exit quickly, and typically reflects a view about a policy or adoption milestone rather than a chart pattern.

What the strikes imply

The heaviest concentrations sit at round-number strikes well above spot, a distribution consistent with structured products sold to wealth channels rather than outright directional bets. Dealers who sold those calls hedge by buying spot into strength, which mechanically dampens upside volatility and lengthens rallies.

The corollary is less comfortable. The same hedging flow reverses on the way down, and a market whose volatility has been suppressed by dealer positioning tends to rediscover it abruptly when that positioning rolls off.
