IREN ended the session at $40.48, down 3.07%.

Large options flow showed a stark split in conviction. The tape was dominated by a $1.98 million long-dated put purchase far below spot, while a smaller $712,000 bull put spread offered a measured bullish offset. Net positioning leaned defensive, with institutions favoring deep tail-risk protection over outright upside exposure.

Options Indicators

IREN’s implied volatility is 80.70%, and despite that high absolute level, its IV percentile is just 0.40%, which indicates current volatility is sitting near the low end of its own historical range. In other words, options are cheaply priced relative to where IREN’s volatility has typically traded, rather than reflecting an elevated premium environment. With an IV/HV ratio of 1.53, implied volatility is still running above historical volatility, suggesting the market is pricing in more forward-looking movement than what has recently been realized. The Call/Put volume ratio is 1.46.

Large Trades

A PUT buy worth $1.98 million was the largest displayed trade, with 12,000 contracts bought at the $10.00 strike expiring on 2029-01-19. With the stock reference price at $40.48, this put sits out of the money, making it a relatively low-strike downside hedge or long-dated bearish wager rather than protection near the current share price. The structure suggests the trader is either positioning for a severe long-horizon drawdown or securing tail-risk insurance far below spot, which gives the trade a clearly bearish tone despite the distant strike.

A bullish put spread with a net debit of $712,000 was the other key displayed trade, built by buying 2,000 contracts of the $40.00 put expiring on 2026-12-18 and selling 2,000 contracts of the $40.00 put expiring on 2026-10-16. Both legs were out of the money versus the $40.48 reference stock price, and the package reflects a spread-style directional stance rather than an outright downside bet. Because it was executed as a bull put spread for a net debit, the intent appears to be a moderately bullish positioning that benefits from stability or upside while shaping risk across expirations, likely combining directional exposure with a degree of hedging or trade-structure efficiency.

Overall, the large-trade flow leans bearish. Although there was a notable bullish put-spread position showing some willingness to express a constructive view around current levels, the dominant signal came from the much larger long-dated $10.00 put purchase, which points to meaningful concern about downside risk over time. Taken together with the broader bulk-order mix, the tape suggests institutions are still more focused on protection or bearish optionality than on outright upside participation.

Strategy Reference

For a low assignment probability, a seller could consider the $20.00 put expiring within 30 to 45 days, given the extreme distance below spot; alternatively, a long put calendar near $40.00 may reduce upfront margin while still expressing a cautious view.
