## Summary

Anthropic announced it has acquired Opaque Systems, a startup that built hardware‑based confidential computing technology for AI. Opaque said its team is joining Anthropic and that the company is winding down its operations. Financial terms of the deal were not disclosed.

Opaque originated as a research project at UC Berkeley’s RISELab a decade ago. Its founders include Ion Stoica, co‑founder of Databricks and Anyscale, and Raluca Ada Popa, an encryption and systems security researcher now at Google DeepMind. Aaron Fulkerson became CEO in October 2023. The firm turned its confidential computing research into production‑grade AI technology and later expanded to “verifiable AI,” providing cryptographic evidence of what ran, where, and under which policies.

Earlier this year Opaque raised a $24 million Series B round at a $300 million valuation, listing Anthropic, ServiceNow and Accenture among its customers. The acquisition could let Anthropic integrate Opaque’s confidential and verifiable AI capabilities into its own offerings, though the impact on Opaque’s existing customers has not been clarified.

## Key points

- Opaque raised a $24 million Series B at a $300 million valuation earlier this year.
- Opaque’s tech adds confidential and verifiable AI capabilities, providing cryptographic evidence of data and model handling.
