Looking ahead to today, September 21, 2026, Lam Research faces the open with recent sector commentary providing a backdrop for the shares rather than a specific company event. In a note on cloud capital expenditure and semiconductor exposure, TechFlow Post reported that JPMorgan highlighted Lam Research among equipment makers positioned to benefit from an expected ramp in global cloud infrastructure spending, grouping the company with other semiconductor and equipment names that the firm views favorably.
