Open Interest Monitor – 21 October 2025 - Global X Uranium ETF (URA) deep dive

Data through market close 2025-10-20

This monitor scans US-listed options markets to identify where open interest (OI) is concentrated, where skew and IV suggest positioning, and how this translates into sentiment signals. Each edition also features a focused options deep dive on a selected underlying—where we analyze volatility structure, positioning, and flow data to better understand what market participants may be anticipating.

URA options deep dive – the quiet power trade behind the AI boom

If the AI trade has a hidden backbone, it’s the energy grid — and that grid increasingly runs through nuclear. Behind the headlines about chips and servers, the real bottleneck is power. Every new data centre needs baseload capacity that renewables can’t yet provide. That’s why uranium equities, and the Global X Uranium ETF (ticker URA), have turned into a quiet momentum engine on the energy side of the AI story.

Liquidity in URA’s options has deepened fast. Daily volume now rivals mid-tier index ETFs, spreads are tight, and volatility is rich enough to matter. For traders, it’s the rare setup where narrative, liquidity, and volatility all align — a playground for structured views rather than outright bets.

The volatility picture: steep wings, calm core

At first glance URA looks overheated. Implied volatility is pinned near the top of its one-year range, with IV Rank pushing 100 %. But that number hides the real story: it’s the shape, not the level, that’s loud.

The 24 Oct weekly isn’t a broad volatility spike — it’s a put-wing blowout. Traders are paying up for short-term downside protection while the at-the-money vol stays well-behaved. In other words, hedging pressure, not panic.

Flow check: who’s doing what

On 20 October, roughly 3 ,800 puts vs 1 ,500 calls traded across URA’s chain — a heavy lean toward downside insurance. The flow clustered around the 52 P and 55 P strikes, both pricing IV in the low 70s. Open interest confirms it:

That stack builds a 55–58 “pin shelf” heading into expiry, with max pain at $54 for the weekly and $52 for the monthly. This is classic short-dated hedging behaviour: keep exposure, insure the tail, roll week by week.

Expected move: the market’s cone of comfort

The 24 Oct at-the-money straddle prices an expected move of ± $3.26 (≈ ± 6.1 %), mapping a $50 – $56.5 range around a $54.5 spot. That’s the market’s “cone of comfort” — stay inside it, and theta rules; break it, and gamma takes over. Beyond October, the term structure flattens; November vol relaxes fast, implying traders see this as noise, not a new regime.

• Hedging pressure, not fear: skew is carrying the whole vol print; ATM vol is unremarkable.
• Short-dated demand: protection is bought, not sold, and only through this Friday.
• Liquidity sweet-spot: tight spreads and responsive vol make URA a practical vehicle for tactical positioning.
• Macro tailwind: nuclear now sits in the same conversation as semis — not hype, but infrastructure.

Why this matters

URA’s chain is now a microcosm of the energy market’s next phase: AI-driven power demand meets nuclear scarcity. Volatility is high because traders care — not because they’re afraid. For options desks, that’s gold: ample liquidity, rich short-dated premium, and a story big enough to last longer than one expiry.

Bottom line

Short-term skew in URA isn’t a warning; it’s a signal that the market’s finally pricing nuclear energy as essential infrastructure. For traders, it’s a live, liquid case study in how narrative volatility behaves — and how to trade around it.

What’s driving open interest shifts this week?

With the Uranium ETF deep dive complete, we now turn our attention to the broader market. Below is our weekly scan of the top 20 names by 1-month open interest growth, filtered for those with at least 100,000 in options volume.

These are the tickers where traders are most aggressively positioning, rolling, or hedging—and the shifts can offer early clues about narrative changes, speculative flows, or hedging intensity. From critical minerals and crypto miners to automation and AI, these OI movers often reflect more than just price action.

Top 20 names by open interest growth

Column explainer (see glossary below)

• IV Rank (%): Position of current IV within its 1Y range
• Total OI: Aggregate open contracts (calls + puts)
• 1M OI % Chg: One-month percentage change in OI
• Options Vol: Most recent trading day total options volume
• P/C Vol: Put-to-call volume ratio (1-day snapshot)

What the data shows

This week’s shifts in open interest highlight a blend of speculative activity in smaller-cap names and renewed defensive positioning in established hedges. At the top of the list, Canaan (CAN), Poet Technologies (POET), and American Battery Technology (ABAT) stand out with month-on-month OI gains between 30–36%. The move suggests traders are gravitating toward niche growth and energy-transition themes, where news flow and volatility often travel hand in hand. ABAT’s unusually high put/call ratio near 1.7 hints at a hedging element beneath the surface.

Volatility exposure also returned to favour through the CBOE Volatility Index ($VIX), which saw a 23% rise in OI as traders rebuilt protection following its recent drop below 20. Meanwhile, gold’s continued draw is evident in the GLD ETF, where open interest rose 15% and implied volatility sits near the top of its annual range. Together, $VIX and GLD point to an undercurrent of caution even as equity indices stabilise.

Crypto-related assets remain another clear thread. Bitfarms (BITF), Terawulf (WULF), and Webull Corp (BULL) joined IBIT, Cipher Mining (CIFR), Cleanspark (CLSK), and Core Scientific (CORZ) among the most active contracts, reflecting steady institutional engagement in digital-asset proxies. For most of these, implied volatility sits mid-range—offering traders room to express directional views without paying extreme premiums.

Large-cap names such as PayPal (PYPL), Pfizer (PFE), and Bank of America (BAC) feature in the second half of the table, each showing modest OI growth but subdued volatility. Their presence reinforces how flows have broadened beyond the pure speculative end of the market into more traditional sectors.

Deeper takeaways

The dispersion in implied volatility is notable. GLD, SLV, and CIFR all show IV ranks above 80%, suggesting expensive premium levels, while BAC, WULF, and CAN remain below 20%, implying that volatility pricing still favours selective selling in lower-beta names.

Put/call ratios help separate hedging from speculation. GLD and $VIX display elevated ratios—clear signs of protection building—whereas POET, CORZ, and SOXS exhibit extremely low readings, typical of call-heavy speculative interest.

Overall, the picture is one of a split market mood: defensive positioning in gold and volatility, offset by sustained appetite for high-risk and crypto-linked plays. Open interest is rising in both camps, underscoring that traders are active but divided—building protection with one hand, and chasing exposure with the other.

Conclusion

Today’s leaderboard tilts toward precious metals and crypto-linked exposure, with a side note of index volatility ($VIX) seeing renewed OI growth. Elevated IV Ranks in GLD/SLV/GDX frame a costlier premium backdrop, while several crypto miners show rising interest on moderate IV. Put/call skews are mixed, suggesting selective hedging rather than broad risk-off. As always, OI is a map of positioning — not a price forecast — and should be read alongside catalysts, liquidity, and realised volatility.

Glossary

• Ticker: the exchange-listed symbol for the underlying stock, ETF, or index. Indices are noted with a $ prefix in general use, but we map them to specific exchange codes in the ticker string.
• Name: the company or ETF name associated with the ticker. ETFs typically describe their focus, such as “S&P 500” or “20+ Year Treasury Bonds.”
• Last: The last traded price of the underlying asset (stock, ETF, or index). This gives a reference point for where the asset currently trades and helps identify how close it is to key strike levels in the option chain.
• IV Rank (%): Implied Volatility Rank (IV Rank) shows where current implied volatility sits relative to the past 12 months. A reading of 0% means IV is at its lowest point of the year; 100% means it's at the highest. Higher IV Rank suggests options are more expensive compared to recent history, which may favour premium-selling strategies.
• Total Open Interest (Total OI): This is the total number of open option contracts across both calls and puts for the underlying. It represents outstanding positions that have not yet been closed or exercised. High OI is often associated with deep liquidity and significant institutional interest.
• 1M OI % Change: Shows how much total open interest has changed over the past month. A rising figure can point to fresh positioning or increased speculation, while a falling number may indicate closed-out trades or reduced interest in the underlying.
• Options Volume: The number of option contracts traded during the most recent session. High volume relative to open interest may suggest new trades are being initiated. Sudden spikes often coincide with market-moving news or upcoming events.
• Put/Call Volume Ratio (P/C Vol): This ratio compares the volume of puts traded to calls on the same day. A ratio above 1.0 implies more puts were traded (often for downside protection), while a value below 1.0 shows call-heavy flow (often speculative or bullish). Extreme readings can highlight skewed sentiment or potential contrarian signals.
