Palantir Technologies Inc. closed at USD 165.86, down 2.16 percent.

Large options trades in PLTR showed a clear defensive tilt, led by a $3.14 million net-debit put structure targeting the 157.50 strike. The biggest displayed transaction leaned bearish, using long 170.00 puts against short 157.50 puts in a ratio-style put spread. A smaller calendar-style combination added put ownership while capping upside through a short 175.00 call. Overall institutional flow favored protection and pullback risk over further upside chasing, making the options tape notably cautious relative to PLTR’s high-flying stock price.

Options Indicators

PLTR’s implied volatility stands at 52.56%, and with an IV percentile of 20.32%, current option pricing sits on the low side relative to its own historical range. In other words, while the absolute IV level is still meaningful, the percentile suggests options are cheaply priced rather than elevated, and the IV/HV ratio of 0.99 indicates implied volatility is broadly in line with recent realized volatility rather than showing a major premium.

The Call/Put volume ratio is 1.27.

Large Trades

A 3-leg put combination with a net debit of $3.14 million was the standout large trade, centered on September 18, 2026 expiration and structured with long 170.00 puts against short 157.50 puts. With the 170.00 strike above the $165.86 reference price, the bought 170.00 puts were in the money, while the sold 157.50 puts were out of the money, making this effectively a bearish put spread expressed in oversized ratio form. The trader paid a substantial net premium to secure downside exposure, while partially financing that protection by selling lower-strike puts, which suggests a directional bearish view on PLTR with downside targeted toward the lower strike area rather than an outright crash bet.

A calendar-style call-and-put combination with a net debit of just $0.01 million was the other displayed large trade, involving a short September 18, 2026 175.00 call, a long September 18, 2026 152.50 put, a long September 11, 2026 162.50 put, and a long September 11, 2026 175.00 call. This is neither a synthetic call nor a synthetic put, but rather a cross-expiration, mixed-option structure with both call and put legs, executed for a very small net debit. All listed strikes were out of the money relative to the $165.86 stock price except the nearer 162.50 put, which sat closer to spot, and the structure appears designed as a tactical hedge or event-driven volatility position rather than a simple outright bullish bet. The short farther-dated 175.00 call helps offset the cost of multiple long optionality legs, indicating caution on upside while keeping protection and near-term convexity in place.

Overall, the large-trade flow leans bearish on PLTR. The key evidence is that the biggest displayed transaction was a meaningful net-debit put structure aimed at downside participation, while the secondary combination also showed a defensive, hedge-oriented posture with put ownership and capped upside. Combined with the broader bulk-order picture, which was tilted toward bearish premium deployment and downside positioning, institutional flow suggests traders are more focused on protection or pullback risk than on chasing further upside in the stock.

Strategy Reference

For traders who agree with the cautious large-trade flow but want to avoid paying rich premium, selling a September 18, 2026 130.00 put could offer a low assignment probability given the distance from spot, while those preferring defined risk and lower margin can use a 157.50/152.50 bear put spread to express a moderate downside view without the outsized ratio exposure of the $3.14 million institutional trade.
