BTC enters the back half of May having pulled back modestly from a strong run — down roughly 1% on both the day and the week — but still up more than 10% over the past month. The more interesting story right now is what the positioning data reveals: an ETF where short activity has been rapidly deflating, borrowing costs remain negligible, and options traders are leaning heavily bullish.
Short interest is not a meaningful force here. At just 0.34% of the float, there is barely any short positioning to speak of. What's notable is the direction of travel: short shares have fallen nearly 48% over the past month, and even with Tuesday's 15% single-day bounce, the absolute level remains a fraction of what it was in mid-April, when shorts peaked at over 1.1 million shares. That April high came as Bitcoin itself was under pressure; as the asset recovered, those positions have steadily unwound. The borrow market reflects this — cost to borrow is just 0.57%, barely above its recent floor, and the lending pool is extremely loose with availability comfortably deep. Nothing in the lending market suggests any stress or squeeze dynamic.
Options positioning reinforces the bullish lean. The put/call ratio of 0.25 is close to its 12-month low of 0.22, and well below the 52-week high of 0.46. This ETF consistently draws far more call activity than put activity, and that skew has become even more pronounced over the past few weeks. The PCR z-score of just 0.37 means positioning is only marginally above its recent average — there is no defensive hedging signal worth flagging. Investors using this product are using it primarily for long exposure, and the options market confirms that bias is intact.
The ORTEX short score of 26.8 — holding in a narrow band of roughly 26–29 over the past two weeks — reflects an unremarkable setup from a short-side perspective. After spiking to nearly 29 in early May as short shares briefly climbed, the score has settled back as those positions were covered. It's a low-conviction short, and the score level suggests that hasn't changed.
For a product like the Grayscale Bitcoin Mini Trust, the standard analytical lens (analyst targets, valuation multiples, earnings reactions) is structurally absent — this is a passive vehicle that simply tracks Bitcoin. What to watch is therefore straightforward: the direction of the underlying asset, any significant shift in the flow of short shares (currently at their lowest in over a month), and whether the PCR drifts meaningfully higher toward the 0.40 range it occupied during the April stress period.
