SandboxAQ has secured a further$150 million in funding, bringing its Series E total to over$450 million.

The quantum-AI firm, which originated at Alphabet in 2016 and spun out in 2022, continues to draw backing from tech heavyweights and financial leaders, including Google, Nvidia, Ray Dalio, and BNP Paribas.

The funding is set to accelerate development in large quantitative models (LQMs), which lie at the heart of SandboxAQ's enterprise solutions.

The models are already being applied across sectors such as life sciences, finance, and navigation. BNP Paribas described the partnership as a key move at the intersection of AI and quantum technology, while Ray Dalio cited his confidence in the company's team and approach.

Recent collaborations have also strengthened SandboxAQ's position in the field. In early 2025, it partnered with Google Cloud to deliver its LQMs via the Google Cloud Marketplace, easing deployment for enterprise users.

Previous deals include a November 2023 alliance with Nvidia to simulate chemical reactions for new material development. In total, SandboxAQ has now raised more than$950 million, achieving a pre-money valuation of$5.3 billion in late 2024.
