US-based Credo to buy Israeli chip startup DustPhotonics

US-listed Credo said it has agreed to buy Israel-based DustPhotonics for US$750 million in cash and about 0.92 million shares.

Credo is a connectivity chip company, and DustPhotonics is a fabless semiconductor firm that makes silicon photonics chips for optical transceivers.

The deal would add silicon photonics to Credo’s portfolio and could include up to 3.21 million more shares if DustPhotonics hits financial milestones.

Credo expects the transaction to close in Q2 2026, pending regulatory approvals and other conditions, and said it would be accretive to non-GAAP earnings per share in fiscal 2027.

🧠 Food for thought

Implications, context, and why it matters.

This acquisition vertically integrates Credo’s AI connectivity business

  • The purchase supports Credo’s plan to own more of its connectivity stack, covering electrical and optical links used in AI data centers 1.
  • The deal brings silicon photonics Photonic Integrated Circuits (SiPho PICs), chips that use light to move data, inside the company. Credo treats them as a core part of its ZeroFlap (ZF) Optical Transceiver platform 1.
  • Credo plans to cut reliance on outside suppliers, shorten development timelines, and improve unit costs as volume ramps 1.
  • Credo expects the combined lineup of ZeroFlap Optical Transceivers, Optical Digital Signal Processors (DSPs), and silicon photonics products to deliver more than US$500 million in optical revenue in fiscal 2027 1.

The deal could signal broader consolidation in the AI hardware supply chain

  • With AI infrastructure spending rising, Calcalist, an Israeli business news outlet, reported that Intel, Nvidia, and Amazon were among the potential buyers for DustPhotonics 2.
  • Chip and systems vendors are trying to sell fuller system building blocks so hyperscale customers, the giant cloud companies building AI data centers, can source more from fewer partners 1.
  • The transaction reinforces that data center links often mix electrical and optical interconnects across AI buildouts 1.
  • Credo frames copper and optical products as complements. The company has moved past copper-only offerings into optical DSPs and its ZeroFlap optical transceivers 3.
