Xsight Labs raising $300M at $2.5B to challenge Nvidia's fabric

A fabless Israeli chip startup that makes programmable switches for AI data centers is reportedly closing one of the larger private financings of the year. According to Globes, Kiryat Gat-based Xsight Labs is raising $300 million at a $2.5 billion valuation, with Fidelity in the round alongside existing backer Atreides Management. The Information first surfaced the deal.

The interesting part is not the headline number, it is what Xsight actually sells. The company builds network chips and fully programmable switches aimed at cloud and AI workloads, and Globes frames the pitch as more efficient language-model processing than Nvidia's graphics processors for cloud providers and neo-cloud operators willing to customize their fabric. That is a bet that the bottleneck for AI training and serving is shifting from raw accelerator count toward the switching layer that stitches those accelerators together.

The other line worth watching is Starlink. Calcalist reports that SpaceX selected Xsight's X2 programmable Ethernet switch as the networking core of its next-generation V3 satellites, which are designed to push more than one terabit per second of fronthaul throughput, roughly ten times what the current V2 Mini satellites deliver. Treat that as a real design win and a marquee reference, not a revenue forecast.

The honest caveat is that most of the specifics here are single-sourced press reporting. Globes uses the word raising rather than closed, the public customer list beyond Starlink is thin, and none of the coverage discloses shipping volumes, gross margins, or how Xsight's silicon actually benchmarks against Broadcom Tomahawk or Nvidia Spectrum in production. Take the valuation and round composition as reported, not as settled.

For buyers, the useful takeaway is that the non-Nvidia fabric shortlist just got another credible name; how quickly Xsight converts design wins into hyperscaler-scale revenue is the thing that will decide whether this round looks cheap or expensive a year from now.
