ARM · Arm Holdings plc

The thesis

Arm Holdings shares have given back the whole late-September rally built on AI-agent server chips, and a Qualcomm jury trial now puts part of Arm's royalty income in dispute. The case for the shares leading the S&P 500 is weak until the second-quarter fiscal 2027 (Q2 FY27) report shows growth above the company's own outlook. Arm's investor calendar lists that report as tentative for 4 November 2026.

The close on 8 October 2026 was $275.29. That is below $275.61, the 18 September 2026 close before the shares jumped on 21 September 2026, so the late-September gain has been fully erased. Benzinga reported on 8 October 2026 that the shares fell more than 3% before the open as pressure from the Qualcomm lawsuit built.

The narrative is saturated: by 28 September 2026 Benzinga described the agent-CPU idea as a sector trade spanning Intel, AMD, Qualcomm and Arm, and the shares have since closed below their pre-rally level. Arm's 29 July 2026 outlook calls for roughly 13% royalty growth in the September quarter, against 22% in the June quarter. This view is wrong if the November report shows royalty growth clearly above about 13% together with a raised December-quarter outlook, and the Qualcomm trial ends without a royalty suspension.

Bullish and bearish views on Arm Holdings plc

The bull case on Arm Holdings plc (ARM), in brief: First-quarter royalties grew 22%. The bear case: Qualcomm seeks a royalty suspension.

Bull case

• First-quarter royalties grew 22%. Arm reported Q1 FY27 royalty revenue of $715 million on 29 July 2026, up 22% year over year, with data-center royalties more than doubling (Arm quarterly results).
• Management describes demand as limited by supply. 24/7 Wall St reported on 17 September 2026 that chief executive Rene Haas called demand "off the charts" and named foundry wafers, memory, substrates and test equipment as bottlenecks. Benzinga tied the 21 September 2026 jump of nearly 13% to Haas's confidence in a custom-chip business of roughly $2 billion.
• The data-center partner list keeps growing. Benzinga reported on 7 October 2026 that Lattice Semiconductor partnered with Arm on control, management and platform adaptability for AI infrastructure.
• Analyst targets sit above the last close. Stockanalysis.com listed a 27-analyst average 12-month target of $305.72 on 1 October 2026, ranging from $140 to $641. StocksToTrade reported that Piper Sandler started coverage on 9 September 2026 at Overweight with a $320 target, citing server-CPU design wins and a custom CPU project for Meta.
• Arm disputes any harm to Qualcomm. The Star reported on 5 October 2026 that Arm's counsel told the jury Qualcomm was "not harmed in the least", arguing that Meta's shift toward AI eyeglasses changed the deal terms for Qualcomm chips.

Bear case

• Qualcomm seeks a royalty suspension. A five-day jury trial began on 5 October 2026 in federal court in Wilmington, Delaware, before Judge Maryellen Noreika. Qualcomm alleges Arm withheld chip-testing tools and leaked a 2024 termination threat, cutting $170 million from a Meta deal, and seeks to stop paying Arm royalties for up to five years, a remedy The Star described as potentially worth billions of dollars.
• A second ruling covers future pricing. The Star reported on 5 October 2026 that a parallel bench trial decides whether Arm negotiated in good faith on its next architecture version, under a Qualcomm agreement that runs through 2033.
• Arm's own outlook implies slower growth. The 29 July 2026 guidance called for September-quarter revenue of $1.330–1.430 billion and roughly 13% royalty growth, down from 22% in the June quarter.
• Arm has lost to Qualcomm in this court before. A Delaware jury found on 20 December 2024 that Qualcomm did not breach the Nuvia license, and Judge Noreika upheld that outcome on 30 September 2025, according to Qualcomm's counsel Paul Weiss. Arm appealed to the Third Circuit on 1 October 2025.
• AI-capex credit stress spills over. Benzinga reported Arm falling on 24 September 2026 in sympathy with Oracle and Blue Owl after reports of a force-majeure notice tied to Project Jupiter.
• Retail money is leaving chip funds. Benzinga reported on 28 September 2026 that retail investors sold a record $300 million of exchange-traded funds in one session, with semiconductor funds hit hardest.

Price setup

Adjusted daily closes put the shares at $275.29 on 8 October 2026. That is 37.4% below the 52-week high of $439.46 and 7.9% lower over three months. The 14-day relative strength index (RSI) stood at 49.9, a neutral reading.

The path since the September jump runs from $310.32 on 25 September 2026 to $289.66 on 30 September 2026, then through a 7% one-day gain on 2 October 2026 in a broad tech rally (Benzinga), to the 8 October 2026 close. The 18 September 2026 close of $275.61 now sits just above the price as overhead resistance. The round $250 level is the next reference below.

Crowding is mixed. The shares show no stretched gap above a rising average, and retail chip-fund selling on 28 September 2026 points to money leaving the group. The overhang comes from events instead: a jury verdict due any session, and a quarterly report about four weeks away.

Catalysts, next 30 days

• 12 October to 15 October 2026: Open Compute Project Global Summit; Arm lists participation, with partner Arm AGI CPU racks and servers on show. It is the first data-center venue since the rally reversed.
• 20 October to 21 October 2026: PyTorch Conference; Arm lists participation. It shows software support for AI workloads on Arm, with no direct revenue read.
• ~4 November 2026 (est.): Tentative Q2 FY27 results. Revenue is measured against $1.330–1.430 billion and royalty growth against about 13%, with the December-quarter outlook showing whether supply limits ease.

Elapsed catalysts

• ~9 October 2026 onward (est.): Jury verdict in Qualcomm's case after the five-day trial that began 5 October 2026; the bench ruling on good-faith negotiation may come separately. This is the nearest event that can move the shares. (passed 3d ago)

What would change the view

The remaining bull case breaks if the Qualcomm jury or Judge Noreika grants Qualcomm a multi-year royalty suspension, or if Q2 FY27 royalty growth comes in at or below the ~13% guide. Either result would leave the agent-CPU story with no support in Arm's reported numbers. A daily close below $250 would mark the market pricing that outcome.

The view turns more constructive if the trial ends with no royalty relief for Qualcomm and the November report shows royalty growth clearly above 13% with a raised December-quarter outlook. A close back above the 25 September 2026 level of $310.32 would show buyers returning to the agent-CPU story.

What it trades with

Arm trades with the CPU group: Benzinga reported on 28 September 2026 that the agent-CPU move spanned Intel, AMD, Qualcomm and Arm. It also trades with AI data-center credit sentiment, as the 24 September 2026 sympathy drop with Oracle and Blue Owl showed. The Qualcomm litigation links the two companies directly; both stocks traded lower on 5 October 2026 as the trial opened. SoftBank Group, the controlling holder, launched an $11.1 billion bond sale on 24 September 2026 to fund a final $10 billion OpenAI investment tranche (Benzinga), so SoftBank funding headlines can move Arm.
