Do you think now is a good time to invest in companies heavily focused on AI?

Arm Holdings saw its stock price climb 0.94% on October 13, 2026, closing at $257.65. This gain occurred as a federal jury in Delaware heard arguments in a legal dispute involving Qualcomm.

Why it matters

The outcome of the trial could impact licensing agreements and the broader semiconductor industry as U.S. AI infrastructure spending is projected to hit $10.3 trillion by 2032. Qualcomm alleges that Arm breached these agreements and interfered with its dealings with Meta Platforms.

Arm Holdings stock closed at $257.65, trading above its 200-day simple moving average of $221.53 but below its 50-day average of $270.41 and 20-day average of $290.20. The company has seen a 52-week range spanning from a low of $100.02 to a high of $452.70.
