ETH, the Grayscale Ethereum Staking Mini ETF, is sending a split signal this week — options traders are the most bullish they've been in a year, while short interest has quietly tripled over the past seven days.
The most striking read comes from options positioning. The put/call ratio has collapsed to 0.23, nearly three standard deviations below its 20-day average of 0.27 — the most call-heavy skew since the fund's 52-week low PCR of 0.16. That reading has fallen steadily from above 0.33 in early June. It now sits closer to the bullish extreme of the one-year range than at any point this year. Traders using options are overwhelmingly positioned for the upside, not hedging against it.
Short interest tells a markedly different story. Shares short more than tripled over the past week, rising from roughly 475,000 to just under 1.9 million — a 293% jump, the sharpest seven-day build in the 30-day history available. At 2.5% of the free float, the absolute level is still modest. But the trajectory is hard to ignore: shorts were adding aggressively into a week when the ETF gained nearly 5%, closing at $17.88, its best monthly performance in over a month (+13%). That means new shorts built positions into price strength, not into weakness.
Despite the short interest build, the borrow market remains loose. Availability runs above 1,150% — meaning roughly eleven shares are available for every one currently borrowed — and cost to borrow has fallen 37% over the week to just 0.46%. Historically the fund has seen tighter conditions: availability dropped to around 413% as recently as June 8, when utilization briefly hit 40%. The current setup is nothing like that episode. Borrow is cheap and plentiful, which means there is no mechanical pressure on the short side. The ORTEX short score has ticked up to 35.6 from 26.5 two weeks ago, reflecting the week's surge in short positioning, but the absolute level remains well within neutral territory.
The gap between what options traders and short sellers are doing is the core tension here. Options positioning is as bullish as it has been all year. Short interest is rising at its fastest pace in a month. The price, for now, has moved in the bulls' favour. Valuation data is stale and analyst coverage absent — this is a crypto-product wrapper, not a conventional equity — so the underlying asset, Ethereum itself, is the real driver. The ETF's staking-income structure adds a yield layer that may be drawing institutional inflows, as noted in recent commentary on the product.
What to watch: whether the short interest build that started July 6 continues to accelerate into another week of price strength — or whether the position gets squeezed back into a quieter range.
