The rebuild in short interest that defined last week's note has reversed sharply — the BTC Grayscale Bitcoin Mini Trust is up 8.7% on the week to $28.22, and the shorts that had been quietly accumulating are now unwinding just as fast.
The positioning story has flipped since the July 1 note. Short interest has fallen 23% over the past week to around 781,000 shares — erasing much of the rebuild that pushed the position to a 30-day high near 854,000 earlier in the cycle. The absolute level, at 0.71% of the free float, remains structurally insignificant. What is notable is the speed of the reversal: shorts that rebuilt into a falling price are now covering into a rising one. The borrow market has also relaxed. Availability is back at its widest reading — effectively uncapped at the data ceiling — meaning the lending pool is as loose as it has been all year. Cost to borrow has dropped sharply too, retreating from a peak above 3.7% on July 1 to 1.27% by July 7. The spike in borrowing costs that coincided with last week's short rebuild has largely unwound alongside the position itself.
Options traders are leaning bullish. The put/call ratio has drifted down to 0.30, sitting roughly 1.5 standard deviations below its 20-day average of 0.32. That makes it one of the more call-heavy readings of the past year — the 52-week low is 0.23, and the current level is closer to that floor than to the 0.46 peak. The trend in the PCR has been consistent: it has been falling steadily since early June, when it was running above 0.38. That sustained drift toward calls lines up with the price recovery — participants are positioned for continued upside rather than hedging against a reversal.
The ORTEX short score of 26.6 is unremarkable and has barely moved over the past two weeks, reflecting how thin the short positioning truly is. There is no signal of meaningful directional conviction from the lending or short-interest side. The trust remains what it has always been: a low-cost Bitcoin wrapper with a very small active short community and a lending pool so deep that any squeeze dynamic is essentially off the table.
What to watch next is whether the call-heavy options positioning — and the short covering — is tracking a genuine shift in Bitcoin sentiment broadly, or simply reflects the trust's week-long price recovery running out of incremental buyers once the shorts finish covering.
