Quantum Computing Stocks Rise as Nvidia Fuels Honeywell's $10B Quantinuum Push

Sep 4 - Quantum computing stocks jumped on Thursday morning after Nvidia NVDA took part in a $600 million funding round for Honeywell's HON Quantinuum unit, a deal valuing the quantum startup at $10 billion.

The news sent shares of IonQ IONQ, Rigetti Computing RGTI, Arqit Quantum ARQQ, Quantum Computing QUBT, and D-Wave Quantum QBTS higher as investors bet Nvidia's involvement could validate the sector's momentum.

Honeywell, which remains Quantinuum's majority owner, said the raise also drew backing from JPMorgan Chase JPM, Amgen AMGN, Mitsui, MESH, and Korea Investment Partners. Honeywell stock ticked up about 1% in premarket trade, while Nvidia edged slightly higher.

The investment highlights Nvidia's shifting stance on quantum computing. Earlier this year, CEO Jensen Huang downplayed the near-term potential of practical quantum machines. But by June, he called the field an inflection point.

With Quantinuum using the capital to accelerate its Helios system and future scaling plans, Wall Street sees Nvidia's vote of confidence as a catalyst across the quantum landscape.
