GDX has had a brutal seven days. The VanEck Gold Miners ETF shed 13.8% on the week to close at $83.78 on Tuesday — a 16.5% retreat in a single month — even as short sellers showed no sign of rushing for the exit.
Short interest is running at 13.2% of the float, a genuinely elevated level for a broad equity ETF. That reading is up 11.9% over the past month, driven by a sharp step-change in late April. From April 22 through April 24, short shares jumped from roughly 35.7 million to 38.9 million — an addition of about 3.2 million shares in two sessions — and stayed near that higher level through May. The monthly build tells the same story: hedgers added meaningful short exposure into GDX's April rally, and they have not unwound it now that prices have pulled back. The ORTEX short score sits at 65.5, in the upper third of the range, consistent with a fund that remains a preferred vehicle for expressing bearish views on gold miners.
The lending market paints a more nuanced picture. Cost to borrow is low at 0.52% — cheap enough that there is no financial pressure on short sellers to cover. Availability has loosened sharply this week, climbing from around 56% on May 13 to 99% on Tuesday, after touching as tight as 9.3% at some point in the past year. That means roughly one share is now available for every share already borrowed — tight by historical standards but meaningfully easier than earlier in the month, when borrowers were scrapping for what little supply existed. The loosening suggests new shares have entered the lending pool, keeping the cost subdued despite the volume of shorts outstanding. Options positioning broadly corroborates the cautious tone: the put/call ratio is at 1.10, in line with its 20-day average of 1.09 and well above the floor of 0.95 hit earlier in May when the ETF was closer to its recent highs. There is no extreme options signal here — just a consistently defensive tilt that has been the baseline posture for GDX options traders for weeks.
The institutional picture adds some texture. Goldman Sachs added 5.5 million shares in Q1 2026, the largest change among top holders, while JPMorgan added 4.1 million shares in the same period — two of the more aggressive additions in the register. Against that, Wells Fargo cut its position by 3.2 million shares, and Morgan Stanley trimmed by 1.2 million. BMO Asset Management remains the largest disclosed holder at 5.4% of shares. The Q1 filing data means these flows predate the current drawdown; how institutions have repositioned since the gold price peaked is not yet visible in the public data.
The backdrop matters for GDX in a way it does not for most individual stocks. Gold itself has been the driver of the miners' outperformance earlier this year, with the metal reaching record highs above $3,000 earlier in 2026 amid fiscal deficit fears, dollar weakness, and central bank demand. Tuesday's news cycle flagged the US federal budget deficit is now projected at $2 trillion for the current fiscal year — among the largest in history — a macro backdrop that historically supports the gold thesis. Yet the miners are underperforming the metal during this week's pullback, amplifying the spot price move as they typically do on the downside.
The next test for GDX is whether the recent short buildup proves well-timed or premature. With borrow availability now loosened and costs still minimal, the structural setup allows shorts to sit comfortably. Watch whether the availability tightens again — a return toward the sub-20% levels seen earlier in the year would signal fresh demand for borrows and a possible new round of short building.
