According to Odaily, the options market for BlackRock's spot Bitcoin exchange-traded fund, iShares Bitcoin Trust (IBIT), indicates growing investor concerns over downside risks. As of Thursday's close, the one-year put-call skew for IBIT turned positive, reaching 0.2%. This suggests that the premium for put options slightly exceeds that for call options, reflecting a shift in market sentiment from neutral to mildly bearish. On the same day, IBIT's share price fell by 1.32%, closing at $59.99. Despite this decline, the fund recorded a net inflow of $125 million, marking the lowest single-day inflow since May 13.
