IREN Ltd closed at USD 36.82, falling 0.79%.

Large options flow in IREN was overwhelmingly bearish, led by a single $2.08 million purchase of December 2026 $35.00 puts. A second block of $1.14 million in October 2026 $32.00 puts reinforced the defensive tone, with both trades occurring on out-of-the-money contracts. No notable bullish blocks were displayed, suggesting institutional positioning aimed at downside protection or outright speculation on a sustained decline.

Options Indicators

IREN’s implied volatility is 83.80%, but with an IV percentile of just 0.79%, current option volatility sits at the very low end of its own historical range, indicating that options are cheaply priced rather than expensive despite the high absolute IV level. The IV/HV ratio of 0.94 also suggests implied volatility is slightly below realized volatility, reinforcing the view that current premiums are on the inexpensive side and that the market’s forward volatility pricing is relatively restrained versus what the stock has recently delivered.

The Call/Put volume ratio is 1.60.

Large Trades

A put buy worth $2.08 million was the largest displayed trade, with buyers taking 3,500 contracts of the December 18, 2026 $35.00 put. With IREN referenced at $36.82, this put was out of the money at the time of the trade, making it a clear bearish positioning that seeks downside exposure over a long-dated horizon. The size and tenor suggest the trader was willing to pay meaningful premium either to speculate on a substantial decline in the stock or to establish protective downside hedging well beyond the near term.

Another bearish options purchase came through as a $1.14 million buy of 5,200 contracts in the October 16, 2026 $32.00 put. This contract was also out of the money versus the $36.82 reference share price, pointing to a downside bet that targets a deeper move lower over time. Relative to the first trade, this strike sits further below spot, which implies the buyer may be positioning for a larger bearish move while still using long premium to define risk. Overall, the bulk-order flow is clearly bearish, with every notable large trade concentrated in put buying and no offsetting bullish flow present, indicating institutional sentiment is skewed toward downside protection or outright negative expectations for IREN.

Strategy Reference

For traders wary of chasing the bearish flow, selling a put spread such as the $30.00/$25.00 put spread may provide a defined-risk way to collect premium with a lower initial margin than a naked put, while keeping the short strike well below the large-block put positioning at $35.00 and $32.00.
