IPO Status
No IPO announced
SandboxAQ shares are not available on public exchanges. See below for listed alternatives with similar technology.
SandboxAQ spun out of Alphabet in 2022 under CEO Jack Hidary, positioning itself at the intersection of AI and quantum technology ("AQ"). Its businesses span post-quantum cryptography migration (a major seller to US government and banks ahead of NIST PQC mandates), quantum sensing for navigation and medical devices, and AI-driven large quantitative models for drug discovery and materials.
It is one of the best-capitalized private companies in the sector: more than $950M raised, including a December 2024 round at a $5.75B valuation with investors including funds tied to T. Rowe Price, Ray Dalio, Eric Schmidt, Nvidia and Google. Separately, in June 2026 SandboxAQ signed a definitive agreement with the U.S. Department of Commerce for a $500 million CHIPS Act R&D award to develop physics-based AI formulations for American semiconductor manufacturing — a government award, not venture funding.
| Round | Amount | Date | Key Investors | Valuation |
|---|---|---|---|---|
| US DoC CHIPS Act R&D award | $500M (definitive agreement) | Jun 2026 | U.S. Department of Commerce | — |
| Series E extension | $300M | Dec 2024 | Ray Dalio, T. Rowe Price funds, Nvidia, Google | $5.75B |
| Series D/E | $500M | 2023–2024 | Breyer Capital, S32, T. Rowe Price funds, Eric Schmidt | — |
Arqit (ARQQ) is the listed quantum-encryption comparable. SandboxAQ's PQC business competes in the same market ARQQ serves.

It spun out of Alphabet in 2022. Investors include Breyer Capital, T. Rowe Price funds, Eric Schmidt, Ray Dalio, Nvidia, Google, and S32.
Does SandboxAQ have government funding?
Yes, separate from its $950M+ in venture funding: in June 2026 it signed a definitive agreement with the U.S. Department of Commerce for a $500 million CHIPS Act R&D award to develop semiconductor-manufacturing formulations.
