Upscale AI in Talks for $2B Valuation in Third Round in Seven Months — Still No Product Shipped (April 2026)

Santa Clara–based AI networking chip startup Upscale AI is in talks to raise a fresh $180–$200 million round at a $2 billion valuation, Bloomberg reported on April 16, 2026. It would be the company's third funding round in seven months and would cement its status as one of the fastest-moving unicorns of the 2026 venture cycle — despite the fact that Upscale AI has yet to ship a product.

What Happened

The new round, which Bloomberg first reported and TechCrunch confirmed the same day, would follow a $100 million seed in September 2025 and an oversubscribed $200 million Series A in January 2026 at a $1.25B valuation, bringing total disclosed funding past $500 million. The Series A was led by Tiger Global, Premji Invest and Xora Innovation, with participation from Mayfield, StepStone, Prosperity7, Maverick Silicon, Intel Capital and Qualcomm Ventures — an unusually strategic cap table that signals how much the silicon industry wants an open alternative to NVIDIA's NVLink-based scale-up fabric.

The lead investor and exact terms of the new round have not been finalised, per Bloomberg's sources.

Key Details

• Founded September 2025 by CEO Barun Kar and Executive Chairman Rajiv Khemani — both veterans of Palo Alto Networks, Innovium, and Cavium with deep networking-silicon backgrounds.
• Flagship product: SkyHammer, a scale-up AI networking platform combining a high-radix switch and full-stack software for interconnecting GPUs, AI accelerators, memory and storage inside a single rack with deterministic latency.
• Open standards bet: SkyHammer targets Ultra Accelerator Link (UALink), Ultra Ethernet (UEC), ESUN, and SONiC/SAI — positioning Upscale AI as the open counter to NVIDIA's proprietary NVLink and NVSwitch stack.
• UEC at 1M-chip scale: the company claims its architecture can support AI clusters of up to one million chips — the scale Meta, OpenAI, xAI and Anthropic are now publicly planning for.
• Shipping timeline: first products — including the high-radix switch — are slated for later in 2026, per the January press release.
• Total disclosed raise to date: ~$300M before this round; ~$500M if the new $200M closes.

What Developers and Users Are Saying

Reaction in infrastructure circles is split. Networking silicon veterans on X and LinkedIn point out that Kar and Khemani previously sold Innovium to Marvell for roughly $1.1B in 2021, and that the pair are among the most credible founding teams in Ethernet switch silicon — a genuine reason to fund them aggressively. "Interconnect efficiency has become a defining driver of performance and economics — not just raw compute," Premji Invest managing partner Sandesh Patnam said in the January announcement, echoing the thesis most LPs have now adopted.

Skeptics are equally vocal. Commentary on HPCwire, TechCrunch and Hacker News threads about the January round consistently flags the same pattern: paying pre-revenue, pre-silicon, pre-product companies at unicorn valuations has a poor historical track record in networking silicon, where tape-out surprises and schedule slips are the norm. The phrase "capital before code" — coined by Tekedia to describe this round — captures the mood cleanly.

What This Means for Developers and Operators

For anyone running or planning GPU clusters, the Upscale AI trajectory matters because it is the clearest sign yet that the industry is willing to finance a genuine open-standard alternative to NVLink. If SkyHammer ships on time, buyers will for the first time have an enterprise-grade scale-up switch silicon option that speaks UALink and Ultra Ethernet natively, which would give AMD, Intel and the rest of the non-NVIDIA accelerator ecosystem a credible rack-scale story. If it slips — the more common outcome for brand-new networking ASICs — the $2B valuation becomes a cautionary tale rather than a leading indicator.

Either way, the round underscores a dynamic every engineer choosing an AI stack in 2026 needs to internalise: the scale-up networking layer is now the single largest architectural bet in AI infrastructure, and open standards are no longer the underdog.

What's Next

Upscale AI has not publicly confirmed a lead investor for the new round, and neither Tiger Global nor the company had responded to TechCrunch's requests for comment as of publication. Watch for: (1) confirmation of a lead, (2) any silicon tape-out milestone before the end of Q2, and (3) public customer reference designs at the OCP Summit in October.
