On September 30, ARM Holdings fell 3.09% in regular trading, trading at approximately $284.89 per share, with turnover of $5.16 billion. The decline came as a massive bearish options order pressured market sentiment amid lingering concerns over AI infrastructure spending.

On the news front, ARM's options market saw a single $192 million deep-in-the-money PUT order concentrated in the January 2027 expiry at a $360 strike price, reflecting a pronounced bearish directional bet by institutional capital. With ARM trading well below the strike, the position signals strong conviction in further downside. The order was almost entirely composed of bearish capital, indicating institutions prefer expressing cautious outlooks through direct downside protection or trend-following short positions.

The move extends volatility triggered after OpenAI announced it would suspend training and testing of its most advanced AI model, which rattled expectations for AI infrastructure spending. ARM plunged over 8% on September 28 before rebounding roughly 6% the following session alongside a broader semiconductor sector recovery. The current decline suggests short-term bull-bear tension remains elevated, with bearish institutional positioning continuing to cap upside momentum.
