Large block trades in options for Nvidia, AMD, and Micron signal significant institutional positioning as market makers adjust prices to meet sudden liquidity demands.

Unusual options activity in the information technology sector reveals distinct institutional positioning across major hardware manufacturers. According to data tracked by Benzinga, large entities executed trades that diverged significantly from standard market valuation, triggering whale alerts. These transactions involved high-volume sweeps and large block trades, forcing market makers to adjust bid-ask spreads to accommodate the immediate liquidity demand. The activity spans short-term expiration dates through multi-year contracts, indicating varied time horizons for these institutional bets.

Nvidia (NVDA) recorded the highest volume of activity, with 193,071 contracts traded at a $220.00 strike price. This bullish call sweep, expiring in September 2026, required the order to be split across four different transactions to fill completely. The total cost to the writer reached $26.5K, reflecting a per-contract price of $106.00. The move added to an existing open interest of 77,947 contracts, suggesting a strong consensus on near-term directional movement despite the short one-day window relative to the reported expiration date.

Micron And Sandisk Face Bearish Pressure

Memory chip manufacturers faced distinct downside bets. Sandisk (SNDK) saw a bearish call sweep involving 884 contracts at a high $1,550.00 strike, totaling $260.0K. This transaction occurred against a low open interest of 1,300 contracts, indicating a concentrated effort to hedge or speculate against price appreciation. Similarly, Micron Technology (MU) experienced a neutral-to-bearish put sweep with 715 contracts at an $800.00 strike, costing $91.9K. These moves suggest institutions are preparing for potential downside risk in the storage sector, diverging from the bullish sentiment seen in other hardware names.

Long-Dated Contracts Signal Structural Bets

Several trades extended well into 2027, reflecting longer-term structural views. Intel (INTC) recorded a bullish call trade for 3.0K contracts at a $100.00 strike, expiring in March 2027. The total transaction value was $26.8K, with an open interest of 12.3K contracts. Conversely, Core Scientific (CORZ) faced a significant bearish put trade of 3.5K contracts at a $13.00 strike. This single trade amounted to $553.0K, the largest individual transaction value in the dataset, highlighting substantial institutional caution regarding the company's mid-term equity performance.

Super Micro Computer (SMCI) and KLA Corporation (KLAC) also displayed notable institutional interest. SMCI saw a bullish call trade of 5.7K contracts at a $40.00 strike, expiring in December 2026. The total value was $27.0K, built on an open interest base of 9.1K contracts. KLAC registered a bullish call sweep with 1.7K contracts at a $170.00 strike, totaling $76.3K. These mid-term positions suggest investors are locking in expectations for sustained performance over the next 90 to 250 days, rather than reacting to immediate daily volatility.

AMD And Palantir Show Mixed Sentiment

Advanced Micro Devices (AMD) experienced a bullish put trade, a counter-intuitive move often associated with hedging existing long positions or complex spread strategies. The trade involved 6.3K contracts at a $550.00 strike, expiring in September 2026. The total value was $32.4K, with a per-contract price of $810.00. In contrast, Palantir Technologies (PLTR) faced a bearish call sweep of 2.1K contracts at a $190.00 strike. The transaction totaled $30.8K, indicating institutional skepticism regarding the company's ability to maintain high valuations into October 2026.

Rigetti Computing (RGTI) completed the list with a bearish put sweep of 669 contracts at a $15.00 strike. The total cost was $30.0K, executed against a substantial open interest of 13.4K contracts. This activity, combined with the broader tech sector trends, illustrates a market where institutional players are actively managing risk and positioning for specific directional outcomes across hardware, software, and data center infrastructure.
