Today at Sibos, industry-standard oracle platform Chainlink announced the successful second phase of its industry initiative to standardize corporate actions processing using oracles and AI. The Chainlink-powered solution allows organizations to receive structured and validated corporate actions data across multiple languages directly into their existing systems in minutes instead of days.
Phase 1 of the initiative, announced at Sibos last year, involved major market infrastructures Euroclear and Swift, as well as six major financial institutions. The collaboration demonstrated how Chainlink oracles can be utilized with large language models to validate and deliver critical financial data cross-chain via Chainlink’s Cross-Chain Interoperability Protocol (CCIP).
Phase 2 expanded participation to 24 of the world’s largest financial services institutions and substantially improved the speed, reach, and accessibility of corporate actions data to introduce a production-grade deployment capable of saving the global financial industry tens of billions of dollars in annual processing costs with minimal disruption to existing processes.
According to the Depository Trust and Clearing Corporation (DTCC), corporate actions processing costs the global financial industry an estimated $58 billion annually. Citi’s 2025 Asset Servicing report reveals the average corporate action event touches more than 110,000 firm interactions and costs $34 million to process.
With 75% of firms re-validating custodian and exchange data manually, standardizing corporate actions data onchain as a unified golden record solves costly inefficiencies stemming from inconsistencies in structure, format, terminology, timeline, medium, and standards for dissemination. Chainlink’s solution mitigates the need for manual reviews by providing all participants, from custodians to asset managers, with real-time, accurate, uniform data.
The system uses the Chainlink Runtime Environment (CRE) to validate AI model outputs and transform them into ISO 20022-compliant messages that are transmitted to the Swift network. CCIP relays the same data across multiple private and public blockchains. Testing revealed nearly 100% data consensus agreement among AI models.
Standardizing corporate actions data onchain is also a critical component of tokenized real-world assets such as tokenized equities.
“I am very excited about our collaboration with Swift, DTCC, Euroclear, UBS, DBS, and many other leading financial institutions on solving corporate actions onchain, a problem that has to be solved in order for tokenized public equity to scale up and work correctly onchain,” said Chainlink co-founder Sergey Nazarov.
“Being able to solve the data validation problem of corporate actions using AI Oracle Networks from Chainlink is a big leap forward in what AI Oracle Networks are capable of, showing that multiple AIs can come to consensus on critical information inside of a Decentralized Oracle Network.”
“Delivering scalable digital market infrastructure means aligning new solutions with the systems institutions already trust,” said Stéphanie Lheureux, Head of Digital Assets Competence Center at Euroclear.
“Industry-wide coordination around standards and interoperability, as demonstrated in this initiative with Chainlink and major financial institutions, is key to achieving that at scale.”
“In an increasingly agentic financial ecosystem, where automation, tokenization, and AI-driven decisioning are reshaping market infrastructure, corporate action compliance must evolve from a fragmented, manual process to a unified, verifiable standard,” said Nigel Dobson, Banking Services Lead at ANZ.
“The Chainlink-led initiative demonstrates how blockchain can deliver attested, real-time corporate actions data across jurisdictions and platforms – reducing operational risk, enabling smart contract automation, and laying the foundation for scalable digital asset servicing.”
