On October 8, ARM Holdings fell 3.16% in pre-market trading to $285.57, with turnover of $8.0725 million. The move comes as the contract dispute between Qualcomm and Arm enters a jury trial phase in Delaware federal court, amplifying market concerns over the stability of Arm's long-term licensing revenue.

The latest escalation centers on Qualcomm seeking to withhold royalty payments for up to five years, a claim potentially worth billions of dollars, while also demanding that Arm be compelled to license its V10 instruction set architecture. Arm has categorically denied the allegations, arguing that Qualcomm has failed to demonstrate any actual damages. The dispute traces back to Qualcomm's 2021 acquisition of chip startup Nuvia, which triggered multiple rounds of litigation. The new accusations further magnify uncertainty regarding Arm's royalty income, contributing to the pre-market pullback.
