Amazon signs multi-billion-dollar fiber deal with Corning as Marvell climbs on S&P 500 inclusion

Amazon said Monday it has agreed to a multibillion-dollar partnership with Corning to boost U.S. manufacturing of optical fiber and related connectivity equipment used in data centers. The companies framed the move as a step toward strengthening domestic supply for the infrastructure behind cloud computing and artificial intelligence workloads.

Optical fiber, often described as “glass threads” that carry data as light indicates, is a core component for moving information between servers at modern data centers. Under the agreement, Amazon said Corning will supply optical fiber, cable, and connectivity solutions supporting Amazon’s expanding data center footprint across the United States.

Amazon and Corning also said the deal will create 1,000 new advanced manufacturing jobs at Corning facilities across North Carolina, along with “hundreds” of additional construction jobs tied to expanding those sites. Both companies said the collaboration includes a workforce development program designed to grow the pipeline of technicians for fiber optic manufacturing roles.

As part of the workforce effort, Amazon said it will expand Corning’s Fiber Optic Technician Training Program with Catawba Valley Community College. Amazon described the program as hands-on education and coursework that would increase the talent pool and create pathways to “high-paying” technical jobs, including roles tied to fiber optics and related manufacturing processes.

In markets, attention was also on Marvell Technology after S&P Dow Jones Indices confirmed the company will join the S&P 500 effective before the open of trading on Monday, June 22, 2026. The same S&P announcement listed Marvell’s ticker as MRVL and said it would replace Pool Corp in the index, with Flex also slated to be added as part of the quarterly rebalance.

S&P 500 inclusion matters because index-tracking funds typically buy shares of newly added companies to match benchmark weights. On Monday, Marvell shares were up sharply in early trading after the confirmation, with one market summary citing a 7.7% gain in pre-open trading, while noting that the news carried over from prior after-hours action.

Beyond the index catalyst, the Marvell move reflects how investors have been repositioning toward AI infrastructure suppliers, particularly firms involved in networking and connectivity chips that sit between data center processors and drive data movement. A separate report attributed Marvell’s earlier eligibility for inclusion to clearing a key profitability hurdle, alongside gains tied to broader AI-related demand expectations.

Amazon and Corning did not disclose the exact dollar size of the agreement in their public releases, nor did they provide a timetable for when new capacity will come online or the projected output volumes. Similarly, while the S&P inclusion provides a clear mechanical reason for buying pressure, it may not fully explain Monday’s trading move, which market summaries tied to other near-term company and industry catalysts. Investors will likely watch for any follow-up details on manufacturing schedules, workforce ramp progress, and how quickly demand for AI data center connectivity converts into sustained revenue for suppliers.
