IREN closed at $34.80, flat with a 0.00% change, after swinging between $32.69 and $34.88 on volume of about 51.7 million shares.

Large options trades in IREN leaned clearly bearish, led by a $4.25 million synthetic put that dwarfed a $2.15 million bullish synthetic call. The oversized long-dated structure paired short $75.0 calls with long $10.0 puts, while additional put buying reinforced the defensive tone. Despite a high headline implied volatility, the low IV percentile suggests institutions are using relatively cheap premium to build conviction-level downside protection.

Options Indicators

IREN’s implied volatility is 88.46%, while its IV percentile stands at 10.36%, indicating that although the absolute level of implied volatility is high, it remains low relative to its own recent history. In that context, options appear cheaply priced and current volatility conditions are on the low side for this name. With an IV/HV ratio of 1.53, implied volatility is still running above realized volatility, showing that the market continues to price in a meaningful forward-looking risk premium despite the relatively subdued percentile reading.

The Call/Put volume ratio is 1.89.

Large Trades

A synthetic put position with a $4.25 million combined size stood out as the largest displayed trade, pairing the sale of 2,500 January 19, 2029 $75.0 calls with the purchase of 10,000 January 19, 2029 $10.0 puts. The structure brought in a net credit of $250,000 and carries a clearly bearish bias, as synthetic puts are typically used to express downside exposure similar to a short stock position. With the stock reference at $34.8, the short $75.0 call is far out of the money and the long $10.0 put is also out of the money, indicating a longer-dated, high-conviction bearish positioning that benefits from weakening share prices while collecting some upfront premium.

A synthetic call with a $2.15 million combined size was the other key large trade, consisting of the purchase of 6,000 November 20, 2026 $40.0 calls and the sale of 3,000 November 20, 2026 $34.0 puts. This trade was established for a net debit of $15,000 and reflects a bullish stance, creating stock-like upside exposure with limited upfront cost. Relative to the $34.8 reference price, the $40.0 call is out of the money while the short $34.0 put is slightly in the money, showing a trader willing to take on downside assignment risk in exchange for leveraged upside participation. Overall, the large-trade flow leans bearish on IREN: although there was one notable bullish synthetic long, the bulk-order picture is dominated by larger bearish positioning, especially through the oversized long-dated synthetic put and additional put buying, which suggests institutional participants are positioning for downside risk to outweigh upside potential.

Strategy Reference

For a low assignment probability on the short side, a seller could consider the January 2027 $20.0 put, which sits well below spot and benefits from the historically low IV percentile to collect premium while keeping a wide buffer against downside moves.
