Arm Stock Jumps With AI CPU Demand Rising - Can ARM Break Above $266.53?

TradingKey - Arm Holdings closed at $251.06 on August 26, up 3.9% for the day. Arm traded toward $260 in premarket trading on August 27. AI infrastructure spending gave investors more confidence to buy Arm Holdings stock due to positive results from NVIDIA. Arm Holdings closed the previous fiscal quarter with record quarterly revenue. Data center royalties also broke records and Arm Holdings has robust demand of more than $2 billion for its new AGI CPUs. With all of this fundamental strength, the question is, will Arm Holdings break $266.53 resistance?

Record Q1 Shows Data Center Is Becoming a Bigger Earnings Driver

Arm's record Q1 revenue shows Data Centers now contribute significantly more to overall earnings. Arm reported $1.29 billion in revenue for fiscal Q1 2027, an increase of 22% compared to the year prior. Of that total revenue, royalty revenue increased 22% to $715 million, while licensing and other revenue increased 23% to $574 million. Non-GAAP operating income was $531 million, producing an operating margin of 41.2%.

The most prominent shift was in royalty revenue in the data centers, which more than doubled from the year prior. Historically, Arm Holdings relied heavily on smartphones and is the primary revenue source, but the company has a clear path to lower that partnership while charging higher royalty fees for Armv9 and Compute Subsystems.

Q2 guidance is also positive, with revenue expected to be between $1.33 billion and $1.43 billion, and non-GAAP EPS expected to be between $0.43 and $0.51. Arm Holdings stock declined after the results of the previous quarter were reported, but this decline was due to smartphone royalty concerns and not poor results in the data center.

AGI CPU Demand Above $2 Billion Raises the Stakes

Arm's largest pivot thus far is the AGI CPU, moving from a predominantly IP licensing business into the sale of a complete production CPU for constructing infrastructures of agentic-AI. From the company directors, demand is estimated above $2 billion for fiscals 2027 and 2028, with first-generation products reaching multiple clients. The company also boasts customers from both the U.S. and China.

The opportunity of selling complete silicon presents Arm with a much larger revenue per deployment opportunity, compared to the constant IP licensing model. It also shifts the business risk. Making direct may-splits and engaging with the supply chain places Arm in competition with its licensees.

AWS, Microsoft and IBM Expand Arm's AI Infrastructure Footprint

Evidence of Arm architecture’s deepening role in hyperscale computing ecosystems continued to pile up in August. Microsoft expects its Cobalt 200 racks to operate in over 25 data centers, while AWS said Graviton, Trainium, and Nitro chip groups had exceeded a $25 billion annual revenue run rate. Graviton revenue commitments grew nearly three times sequentially, and Graviton5 adoption occurred at double the pace of the prior generation.

Another strategic validation occurred to Arm architecture on August 24 when IBM announced a new dual-architecture processor for IBM Z and LinuxONE that will run Arm-native software alongside IBM workloads. The immediate revenue impact will likely be light, but it does extend Arm architecture to mission-critical systems used by banks and insurance companies.

Raymond James estimates the server CPU market will peak at close to $201 billion by 2030, due in large part to the increased demand for agentic AI and the subsequent requirements for processors to control and coordinate accelerators, databases, retrieval, security and tool execution.

NVIDIA Earnings Add a Fresh Tailwind, but Valuation Still Matters

Data centered on hyperscale AI spending from NVIDIA’s recent earnings calls was somehow more positive for Arm, saying that continued investments in custom silicon will help Arm through cloud AI services and NVIDIA’s own Arm-based CPU offerings. The pre-market jump for Arm on August 27 reflected the improved sentiment across the sector.

The risk is that Arm's valuation leaves room for error on execution. Royalty income from smartphones is cyclical, the AGI CPU introduces risk from manufacturing, and Arm needs to increase its silicon business while maintaining its relationships with its architecture licensees. A strong AI market could support the valuation, but a slowdown in licensing, royalty income, or the conversion of AGI CPUs could result in a sharp decrease in valuation multiples.

ARM Technical Analysis: $266.53 Is the Breakout Test

In this chart, ARM is illustrated as being close to $251.31, but the last completed session closed at $251.06 with some pre-market buying pushing the price to $260. While the short-term projection has improved, the crossing of $255.92 remains a moving average below the price in the pre-market session, pending regular session confirmation.

The strong resistance line sits at $266.53 and represents the top of the descending side of the broader symmetrical triangle. A break of $266.53 would confirm an even stronger recovery and would then have sights set on $284.32, and eventually on $299.07.

The RSI at 62 in the chart illustrates a growing bullish trend, but is not yet in the overbought territory at 70. If the pre-market buying starts to peter out, then $248.08 would come into play as support. Should the price break below this, it would weaken the recovery and bring $233.55 into play again, followed by $220.31.

·       First support: $248.08

·       Strong support: $233.55

·       Breakout resistance: $266.53

·       Targets if resistance is broken: $284.32 and $299.07

·       RSI: Around 62, bullish, not overbought

Why is ARM stock rising?

ARM is benefiting from positive momentum in semiconductors after NVIDIA reported earnings. ARM has also posted record revenue after Q1, and data-center royalties are continuing to grow. Additional evidence points to the large cloud Arm infrastructures of AWS, Microsoft, and IBM expanding.

What level does ARM need to break for a stronger rally?

The level is $266.53. A break above this line would solidify the triangle, and a follow on break above the line at the boundary of the triangle would support a bullish structure and target $284.32 and potentially even $299.07.

Bottom Line

The core trend of Arm’s fundamental story is where investors care most. Example: the increase in data-center royalties, $2B+ of demand for Arm’s AI-focused CPUs (central processing units), and rapid deployment of Arm-based technology by major cloud and enterprise customers. An additional vote of confidence is the positive outlook for AI by Arm’s largest competitor, NVIDIA. Risk increases for Arm including valuation and execution risk as it moves beyond its traditional CPU businesses. Technically, a rebound for Arm begins above $248; however, $266.53 still needs to break to make the rebound a stronger confirmation for a bullish continuation.
