ARM Bulls Double Down as Smart Money Buys $30M Calls

Amid the ongoing surge in AI infrastructure demand and continued expansion in ASIC and AI inference workloads, shares of $Arm Holdings(ARM)$   continued to rally on Wednesday, rising more than 6% intraday. Near the stock’s recent highs, the options market also saw a massive long-term bullish trade worth more than $30 million, signaling that institutional investors are continuing to bet on ARM's long-term AI story.

The trade involved 5,000 contracts of the August 21, 2026 $170 Call, with total premium reaching approximately $30.95 million. The transaction was marked as a Cross trade, typically associated with institutional block activity. More importantly, the trade was labeled as Opening. Given that the contract's prior open interest stood at only 776 contracts while same-day volume surged to 5,000 contracts, the flow strongly suggests the creation of a sizable new bullish position.

Structurally, this is a classic deep in-the-money (Deep ITM) Call trade. With ARM stock currently trading around $218, the purchased $170 Call carries a Delta of roughly 0.81, meaning the option behaves similarly to the underlying stock itself. Trades like this are usually less about short-term speculation and more about“Long Stock Replacement”strategies, where institutions use options to gain leveraged long-term bullish exposure with greater capital efficiency.

What the market is really pricing in now is ARM's long-term strategic value within the AI data center and ASIC ecosystem.

As $Amazon (AMZN.US)$ , $Alphabet-A (GOOGL.US)$ , $Microsoft (MSFT.US)$ , and $Meta Platforms (META.US)$ continue ramping up development of in-house AI chips, more AI ASIC and data-center CPU designs are increasingly being built on ARM architecture. At the same time, the AI industry is gradually shifting from training toward inference, driving rising demand for low-power, high-efficiency CPUs — an area where ARM is positioned as a major beneficiary.

The company's latest earnings report further reinforced that narrative. Management stated that data center could eventually become ARM's largest business segment, while demand for AI-related products has significantly exceeded expectations. This suggests the market is increasingly re-rating ARM from a traditional IP licensing company into a core AI infrastructure platform asset.

Still, risks remain. ARM's valuation has already expanded significantly, while supply-chain constraints and advanced packaging bottlenecks continue to pressure the AI semiconductor industry. Whether ARM can continue delivering high growth will largely depend on whether the AI capex cycle continues to accelerate.

Overall, this more-than-$30 million long-term Call trade sends a very clear medium- to long-term bullish institutional signal. Investors are continuing to position for ARM to emerge as one of the key winners in the AI inference, ASIC, and data-center CPU cycle.
