Eliyan Hits $1bn Valuation After $145m Series C Round

Chiplet interconnect startup Eliyan has been valued at $1 billion following a $145 million Series C funding round, Data Center Dynamics reports.

The round makes Eliyan the latest semiconductor company to cross the billion-dollar valuation threshold as investors bet on chiplet-based architectures. The $145 million raise, reported by Data Center Dynamics, marks a substantial capital injection for a company whose technology addresses one of the industry's most pressing engineering problems: how to connect chiplets together efficiently.

Eliyan's core business is chiplet interconnect technology. As semiconductor designers hit the limits of monolithic chip scaling, the industry has shifted toward packaging multiple smaller dies — chiplets — into single packages. The quality of the interconnects between those dies directly determines performance, power consumption and cost of the resulting multi-die systems.

The $1 billion valuation assigned in the Series C reflects investor confidence in that market shift. Data Center Dynamics, which reported the funding round, positioned the deal as a milestone for the startup.

Why chiplet interconnects matter

The move to chiplets has become one of the defining trends in semiconductor design. Rather than fabricating ever-larger single chips, manufacturers assemble systems from modular dies produced on different process nodes. That approach cuts costs and improves yields, but it shifts the engineering burden onto the interconnect layer.

Companies in this segment compete to deliver links that move data between chiplets at high bandwidth while minimizing power draw and latency. That technical challenge sits at the center of Eliyan's business, and it explains why investors are willing to underwrite a $145 million round at a $1 billion valuation.

A well-capitalized niche

The Series C figure places Eliyan among the larger semiconductor funding rounds of the past year, according to the Data Center Dynamics report. The capital arrives as data center construction, AI compute demand and advanced packaging capacity all expand simultaneously.

For a startup operating in chiplet interconnects, the addressable opportunity grows with every design that abandons the monolithic approach. The major chipmakers' adoption of multi-die architectures has effectively created a market for companies that solve the connection problem — and Eliyan's new valuation signals that investors see the company as a credible contender in that market.

What comes next

With $145 million in fresh capital and unicorn status secured, the immediate questions for Eliyan are commercial: converting interconnect technology into design wins, and scaling to meet demand from chipmakers building multi-die systems. The company now has the balance sheet to pursue that agenda.
