AI chiplet startup Eliyan draws takeover interest months after $1 billion valuation

Eliyan, a Santa Clara semiconductor startup, has attracted at least one takeover bid. That comes barely two months after it raised $145 million at a $1 billion valuation.

The company has hired an investment bank to weigh its strategic options. Those options include a potential target valuation of $3 billion, which would roughly triple the price tag investors put on it in late July.

A bid, a banker, and a bigger number

As of early October 2026, Eliyan has received at least one offer. The identity of the bidder has not been disclosed.

The $3 billion figure is a potential target, not an agreed price. Nobody has publicly committed to paying it.

One familiar name has circled before. Eliyan previously held preliminary acquisition discussions with Arm, which also invested $5 million in the startup. Arm has not placed a formal bid as of October 2026.

What Eliyan actually builds

GPUs currently operate at only 30-40% efficiency because of bandwidth limitations. The expensive chips spend much of their time waiting for data instead of crunching it.

Eliyan’s answer is high-speed chiplet interconnects. Chiplets are smaller pieces of silicon combined into one package, rather than one giant monolithic chip.

The company’s products include NuLink PHYs and NuGear chiplets. A PHY is the physical layer that actually moves bits between components, essentially the wiring and signaling that lets chiplets talk to each other quickly.

Eliyan says its technology is silicon-proven on advanced fabrication nodes, including 3nm processes. The startup also holds more than 100 patents. It has been expanding into electro-optical solutions, aimed at delivering high-bandwidth, low-power connectivity.

How Eliyan got here

Eliyan was founded in 2021. Across multiple rounds since then, it has raised more than $250 million in total.

The biggest chunk arrived on July 29, 2026, when the company closed its $145 million Series C. That round valued Eliyan at $1 billion, officially earning it unicorn status.

The investor list leans heavily strategic. Backers in the Series C include Seligman Ventures, Cisco Investments, and Lumentum, among others.

The funding was earmarked to improve data transfer speeds in AI accelerators.

Eliyan plans to ship its initial chiplet products by the end of 2026, with expectations of significant revenue in the following year.

What this means for the AI hardware race

Going from a $1 billion round in late July to a potential $3 billion target by early October is an aggressive repricing.

First, the bidder. An undisclosed offer could come from a chip designer, a hyperscaler, or a networking company.

Second, Arm. Arm has history with Eliyan through both its $5 million investment and earlier acquisition talks.

Third, execution. The plan to ship initial chiplets by the end of 2026 is still a plan. Delays would weaken Eliyan’s negotiating position, while a clean launch would strengthen it considerably.
