Lumentum stock surges as AI demand and hyperscaler spending soar

Shares of Lumentum Holdings extended their strong run on Wednesday, climbing as much as 11.7% intraday as investor enthusiasm around artificial intelligence infrastructure continued to build.

The stock was trading at $766.85, up 9.1% at the time of writing, putting it on track for its largest percentage gain since March 24, when it rose 10%, according to Dow Jones Market Data.

The latest move adds to an already remarkable performance, with shares up nearly 108% year to date and more than 1,105% over the past 12 months.

The rally follows a blockbuster first quarter during which Lumentum gained 84% and secured inclusion in the S&P 500 index, highlighting growing investor confidence in companies tied to AI infrastructure.

AI infrastructure demand drives surge

Lumentum’s gains have been closely tied to accelerating demand for optical networking technologies used in AI data centers.

While chipmakers like NVIDIA Corporation supply processors, companies such as Lumentum provide the optical components that enable high-speed communication between those chips.

The company has benefited from increased capital spending by hyperscalers, which has lifted both Lumentum and Coherent shares sharply over the past year.

Coherent’s stock was also higher on Wednesday, rising 4%.

Both companies were added to the S&P 500 on March 23 as part of the index’s quarterly rebalancing, and their shares surged following the inclusion, underscoring investor appetite for AI-linked infrastructure plays.

Lumentum has also pointed to a significant long-term opportunity, estimating that the total addressable market for optical interconnects could grow to $90 billion by 2030, up from around $18 billion currently.

Nvidia partnership boosts outlook

Investor sentiment has been further supported by Lumentum’s deepening relationship with Nvidia.

The chipmaker recently announced a $2 billion investment in Lumentum, alongside a similar commitment to Coherent, as part of its strategy to build advanced optical infrastructure for next-generation AI data centers.

In addition to the equity investment, Nvidia has also committed to multibillion-dollar purchase agreements with both companies, providing greater visibility into future demand.

The partnership is seen as a key catalyst for Lumentum, positioning it at the center of the expanding AI hardware ecosystem.

The company also revealed a multi-billion-dollar contract with a major hyperscaler for its optical circuit switching technology, reinforcing expectations for sustained revenue growth.

Expansion plans and analyst optimism

Lumentum is also scaling its production capacity to meet rising demand.

The company recently announced plans to establish a new manufacturing facility in Greensboro, North Carolina, aimed at expanding the output of ultrahigh-powered lasers and other key components.

Analysts have responded positively to these developments. BNP Paribas analyst Karl Ackerman raised his price target on the stock to $1,040 from $625, citing increased demand for optical transceivers, lasers, and related technologies used in AI data centers.

Market participants are increasingly revising their expectations for Lumentum’s earnings potential, with some suggesting that the company’s earnings power could be structurally higher as AI adoption accelerates and contract visibility improves.

With strong momentum, strategic partnerships, and expanding production capabilities, Lumentum’s recent rally reflects broader investor confidence in the long-term growth of AI infrastructure and the companies enabling it.
