PsiQuantum - Series E
$750M Raised
There’s something about a company named PsiQuantum chasing a future where light itself bends to compute the impossible. It sounds like sci-fi, sure, but the numbers hitting bank accounts tell a different story. $750 million in Series E funding. A $6.75 billion valuation. And if you’re wondering whether this is smoke and mirrors or real photonic firepower, ask BlackRock and NVIDIA why they’re doubling down on a bet most can’t even spell, let alone explain.
This isn’t some basement quantum startup tinkering with cryo-sorcery. PsiQuantum is tapping the same silicon foundries that keep your smartphone running and rerouting them to build a machine that doesn’t just simulate chemistry, it reinvents it. Founded by Jeremy O'Brien, Terry Rudolph, Pete Shadbolt, and Mark Thompson, PsiQuantum is the quantum world’s answer to the old “go big or go home.” Except in this case, “home” is a 300mm CMOS line at GlobalFoundries, and “big” is a utility-scale quantum computer parked near Brisbane Airport by 2027.
O’Brien, former Stanford University and Bristol professor and co-creator of the Variational Quantum Eigensolver, doesn’t speak in MVPs. He talks in millions. One million physical qubits. That’s the goal. And they’re not just dreaming in photons. They've already pushed out over 1,000 wafers, cracked sub-0.1 dB/cm losses on silicon nitride waveguides, and inked deals from Cook County to Queensland. This is physics, politics, and capital converging in a way that actually matters.
Forget the usual quantum suspects. PsiQuantum isn’t battling for supremacy in the science fair. They’re wiring a modular architecture that can scale without breaking physics, or the bank. BlackRock’s in for the second time. Microsoft’s M12, Microsoft's Venture Fund. Baillie Gifford. Founders Fund. Atomico. The real sharks don’t circle unless they smell blood in the market water. And right now? There’s a quantum feeding frenzy.
And let’s talk brass tacks. Quantum isn’t just some nerd fantasy anymore. PsiQuantum is targeting what classical computing can’t touch, catalyst simulations, energy grid optimizations, quantumproof encryption. Real-world, trillion-dollar upside. And that $940 million AUD from the Australian Government ? That’s not a grant. That’s a handshake with the future.
PsiQuantum isn’t chasing hype, they’re building the hardware of tomorrow using the infrastructure of today. And with a leadership team spanning four continents and a chip that makes electrons look clumsy, they’ve set the roadmap. Brisbane in 2026. One million qubits in 2027. Commercial launch by 2028.
