On September 25, Marvell Technology rose 3.14% in regular trading, trading at $267.06 per share, with turnover of $1.615 billion.

On the news front, broad semiconductor and optical communication stocks rallied as AI infrastructure spending sentiment strengthened. Anthropic's $11.6 billion cloud computing agreement with Akamai reinforced confidence in AI-related capital expenditure, lifting the broader chip sector. Marvell was among several semiconductor names gaining over 2% in pre-market trading before extending gains into the regular session.

The move also comes amid a series of recent company-specific catalysts. Earlier this week, Marvell expanded its collaboration with AT&S to boost IC substrate capacity for AI and cloud infrastructure at AT&S's Malaysia facility. Additionally, the company recently demonstrated industry-first 2nm-based single-channel 400G optical interconnect technology at the European Conference on Optical Communications, positioning it for next-generation 3.2T data center upgrades. Analyst sentiment remains supportive, with Morgan Stanley raising its target price to $268 and Seaport Global initiating coverage with a Buy rating and a $270 target.
