Since yesterday, Deribit buyers have bought 2,026 BTC in $70K calls for the 25SEP26 expiry, paying $2.58 million. Two blocks totaling 1,000 contracts filled with spot near $64.8K and implied volatility at 33.53%, followed by a second wave of roughly 1,000 contracts.
Why it matters
Call buying expresses upside exposure, and the concentration at one strike gives the CPI-linked range-break setup a clear level to watch. With spot near $64.8K at execution, the $70K strike is the upside level being targeted by this positioning, while the 25SEP26 expiry places the trade in a forward-looking time frame.
Market impact
The flow is bullish options positioning, not proof that BTC will break higher. The key markers are continued activity around $70K calls, the $64.8K spot reference and 33.53% implied volatility.
