MaxLinear shares surge on AI data center chip demand

MaxLinear shares experienced a significant surge, gaining over 50% in September 2026 and closing at $105.93 on October 2, a single-day increase of 14.99%. This growth is largely attributed to accelerating demand for optical networking chips used in AI data centers.

The company produces digital signal processors (DSPs) that connect servers within these facilities. Management has significantly raised its optical data center outlook, with guidance for this business segment increasing from an initial $100 million at the start of the year to a midpoint of $220 million. CFO Steven Litchfield noted that chip prices remain firm and lead times for new orders are currently 26 to 28 weeks.

Beyond market demand, the stock's performance was bolstered by a positive credit outlook from S&P Global Ratings and bullish price targets from analysts at StoneX and Stifel. While technical indicators show the stock is in an overbought zone, the upward trend remains driven by the AI infrastructure megatrend.
