In the first few months of 2026, the pace of mergers and acquisitions in the optical chip industry has been so intense that it is almost dizzying.
On March 2 alone, Nvidia announced $2 billion investments in both Lumentum and Coherent. Three weeks later, it poured another $2 billion into Marvell. In the same month, Credo Technology announced the acquisition of Israeli silicon photonics company DustPhotonics for $750 million. Just a few months earlier, Marvell had completed its acquisition of Celestial AI for up to $5.5 billion. When these deals are added together, the capital flowing into the optical interconnect sector alone has exceeded $10 billion in just six months.
A large number of these acquisitions and investments are all pointing in the same direction — optical chips. The explosive expansion of AI computing power has pushed optical chips to become the central hub determining whether the entire computing infrastructure can operate normally. Whoever can build a moat in this critical link will possess a strong defensive advantage in the AI infrastructure race for the coming years.
