BTC short sellers have nearly abandoned the trade. Yet options traders are the most defensively positioned they've been in weeks. The two signals point in opposite directions — and the borrow market is starting to reflect the tension.
Short interest in the Grayscale Bitcoin Mini Trust has collapsed. Shares borrowed have fallen 56% over the past month, landing at just 0.26% of the float as of May 20. That's the lowest level since early April.
To put the scale of the unwind in context: shorts peaked above 1.1 million shares in mid-April. They now sit at roughly 289,000. The retreat has been consistent across every week of May without exception.
The lending pool reflects that exodus. Availability stands at 9,621% — meaning there are roughly 96 shares available to borrow for every one currently lent out. The borrow market has never been looser in recent history. Nothing in the lending data signals any pressure on remaining short holders.
That makes the cost-to-borrow move harder to explain. CTB doubled over the past week to 0.75% — the sharpest week-on-week rise since April. In absolute terms, 0.75% remains negligible. But the direction is unusual when availability is this wide.
The most plausible read: as the pool of active borrowers thins dramatically, even small shifts in the remaining demand can produce outsized percentage moves in the quoted rate. It is noise in a very small market, not a signal of renewed shorting pressure.
The options picture is more interesting. The put/call ratio has held above 0.30 for three consecutive sessions — sitting at 0.31 on May 21, roughly 2.4 standard deviations above its 20-day mean of 0.25. The 52-week high is 0.46, so this isn't an extreme reading in absolute terms. But the sustained elevation is notable.
The prior article noted this shift began abruptly around May 18, after the PCR had barely moved from the low-to-mid 0.24 range all month. That shift has not reversed. BTC is down about 2.5% on the week, and put buyers appear to be maintaining tactical hedges against further softness rather than unwinding them.
The divergence between the two signals is the story here. Short sellers see no reason to press the trade. Options traders are paying for downside protection anyway. The PCR elevation may simply be portfolio-level hedging on Bitcoin exposure at the ETF level — not a directional bet, but insurance held while the asset consolidates.
