VCs embrace quantum computing in a crowded semiconductor market

VCs embrace quantum computing in a crowded semiconductor market Jacob Robbins Wed, September 2, 2026 at 9:58 PM GMT+2 2 min read VC investment in quantum computing notched a record $2 billion in Q2 across 23 deals, accounting for a third of dollars in the chips and datacenters vertical, according to a new PitchBook report . Quantum's marquee event this quarter was Quantinuum's IPO , which accounted for most of the $19 billion in quantum exit value and was the first major test of the technology in public markets. On the VC side, Oxford Quantum Circuits raised a £260 million Series C led by Bullhound Capital .

Strategics are eyeing quantum technologies, too. Miraex , a quantum hardware startup, was bought in June following Quantum Circuits $538 million sale earlier this year. Overall, investment in chips and datacenters fell for the second consecutive quarter, hitting $6.

6 billion across 133 deals in Q2. Despite the pullback from recent highs, 2026 is still on pace to exceed 2025's record of $21. 6 billion.

The declines were concentrated in semiconductor chip design startups, which posted their weakest quarter since Q1 2025 at $1. 7 billion. While newer chip design entrants like Etched , d-Matrix , and Ricursive Intelligence are making waves, the dominance of larger players has given investors pause.

"If Nvidia owns 93% or 94% of the market and they still continue to blow out earnings every quarter, you become like, 'Well, if you're the other 6%, how do you win? '" asked David Yakobovitch, GP at DataPower Capital , a firm that backs AI infrastructure companies like Nscale , Cerebras , Groq , and Crusoe . "Is that market share going to go down enough to create enough money for all the other players?

" Even challengers with real momentum face a long road. "It's R&D, it's hard tech, it's deep tech, and chips often take years and years and years," Yakobovitch said, noting that it took companies like Cerebras and SambaNova a while to reach commercial viability.

Anthropic signed a $35 billion computing deal with Nvidia -backed Lambda , The Wall Street Journal reported. That deal comes just weeks after Anthropic committed to a $45 billion, six-year agreement with Nscale for access to its compute capacity. And on the venture side, TensorWave raised a $350 million Series B in June at a $1.
