Ayar Labs Raises $150M Series C+ for Co-Packaged Optics in AI Data Centers

Ayar Labs Secures $150M Series C+

Ayar Labs, a leader in co-packaged optics (CPO) solutions for AI scale-up, has raised $150 million in Series C+ funding. The round was announced on September 10, 2026, and includes participation from Alchip, NVIDIA, Intel Capital, MediaTek, AMD, and Wiwynn.

What Ayar Labs Does

Ayar Labs develops optical interconnect technology designed to replace copper with lasers in AI data centers. The company's co-packaged optics solutions target AI scale-up — the challenge of connecting accelerators at the scale and bandwidth required by modern AI workloads.

As AI clusters grow, copper interconnects face physical limits on bandwidth and reach. Optical interconnect is widely viewed as the path forward for scaling these systems, and Ayar Labs is positioned as a leader in the CPO category.

The Round at a Glance

• Company: Ayar Labs
• Sector: Co-packaged optics / optical interconnect for AI data centers
• Round type: Series C+
• Amount raised: $150 million
• Announced: September 10, 2026
• Investors: Alchip, NVIDIA, Intel Capital, MediaTek, AMD, Wiwynn

A Strategic Investor Syndicate

The composition of this round is as notable as its size. The investor list reads as a cross-section of the semiconductor and AI infrastructure ecosystem:

• NVIDIA — the dominant supplier of AI accelerators, whose systems depend on high-bandwidth interconnect.
• AMD — a major accelerator and compute vendor competing in the same AI data center market.
• Intel Capital — the investment arm of Intel, another significant player in data center silicon.
• Alchip — an ASIC design services provider.
• MediaTek — a major fabless semiconductor company.
• Wiwynn — a data center and cloud infrastructure hardware manufacturer.

Having both NVIDIA and AMD on the same cap table, alongside Intel Capital, is unusual and underscores how strategically important optical interconnect has become across the compute landscape. The presence of Alchip, MediaTek, and Wiwynn adds exposure to custom silicon design and system-level manufacturing — the layers where CPO technology must ultimately be integrated and deployed.

No single lead investor was designated for the round.

Why This Round Matters

The $150 million Series C+ gives Ayar Labs substantial capital to scale a technology that sits at a critical bottleneck in AI infrastructure. As AI data centers scale up, the interconnect between accelerators increasingly determines what system sizes are practical. Replacing copper with optical links is one of the more consequential transitions underway in data center architecture.

The involvement of system and silicon vendors as investors suggests alignment across the supply chain — a meaningful advantage for a component technology that must be designed into platforms built by others.

What Comes Next

With $150 million in new funding and a syndicate spanning accelerators, custom silicon, and system manufacturing, Ayar Labs is positioned to push co-packaged optics further into mainstream AI data center deployments. The company's progress will be a key indicator of how quickly optical interconnect moves from emerging technology to standard infrastructure.

Summary

Ayar Labs has raised $150 million in Series C+ funding, announced September 10, 2026. The company develops co-packaged optics solutions for AI scale-up, replacing copper with lasers in AI data centers. Investors in the round include Alchip, NVIDIA, Intel Capital, MediaTek, AMD, and Wiwynn.
