Secure Multiparty Computation Market to Reach $1.4B
The global market for Secure Multiparty Computation (SMPC) is projected to grow from $824 million in 2024 to $1.412 billion by 2029. This represents a compound annual growth rate of 11.4%. SMPC technology allows multiple parties to jointly compute a function over their inputs while keeping those inputs private.
- The foundational concept for SMPC dates back to 1982 with Andrew Yao's "Millionaires' Problem," a thought experiment where two millionaires want to know who is richer without revealing their actual wealth. This established the field of secure two-party computation, which was later generalized to multiple parties. - Key industry applications include fraud detection in financial services, where competing banks can jointly analyze transaction data to identify patterns without sharing sensitive customer information. In healthcare, it allows for collaborative medical research across institutions without compromising patient privacy, which is crucial for compliance with regulations like HIPAA. - SMPC is a critical enabling technology for privacy-preserving machine learning and AI. It allows multiple parties to train AI models on their combined datasets without any single party having to expose their raw data, a technique often used in conjunction with federated learning. - The technology is distinct from homomorphic encryption (HE), another privacy-enhancing technique; while HE allows computation on encrypted data by a single party, SMPC enables joint computation among multiple parties who do not trust each other. SMPC often has lower computational overhead compared to fully homomorphic encryption. - In the blockchain and digital asset space, SMPC is used to enhance security for private key management. By splitting a private key into multiple parts held by different parties, it eliminates a single point of failure for securing crypto assets in wallets and custody solutions. - The deep tech sector in Turkey, which includes companies developing technologies like AI and blockchain, has seen a significant rise in funding, with companies raising $29.6M in the first ten months of 2025, a 439% increase from the same period in 2024. Venture firms like Diffusion Capital Partners and 212 are actively investing in Turkish deep tech and B2B tech startups with global potential. - Major technology companies like Google and Microsoft are key players, providing the cloud infrastructure and tools necessary to build and deploy scalable SMPC solutions. An industry group, the MPC Alliance, was formed in 2020 to accelerate the awareness and adoption of the technology.
