SIX and Chainlink have announced a major integration bringing equities data onchain for the first time. The partnership makes market data from SIX Swiss Exchange and BME Exchange accessible across blockchain networks.

Together, both exchanges represent over €2 trillion in combined market capitalization. This data is now available to more than 2,600 applications across 75 public and private blockchains. The move opens new doors for digital asset developers and financial institutions globally.

SIX Expands Its Blockchain Market Infrastructure Reach

Through the integration, SIX is using Chainlink’s DataLink service to publish institutional-grade data. DataLink is a data publishing platform built on the Chainlink standard.

It supports secure data delivery across leading public and private blockchain ecosystems. SIX operates market infrastructure in both Switzerland and Spain, placing it at the center of regulated financial markets.

The data now available covers equities listed on SIX Swiss Exchange and BME Exchange in Spain. Developers can access this data programmatically within smart contract environments at scale.

This creates a structured path for building financial applications directly onchain. The entire process works within infrastructure already trusted by large institutions.

Matthew Nurse, Head of Market Data at SIX, noted that the integration “delivers real-time, high-value market data while bringing flagship Swiss and Spanish blue-chip equities onchain via Chainlink’s DataLink.”

He added that it “enables digital asset applications to access trusted market data through proven, secure infrastructure, fostering trust and innovation across global financial ecosystems.”

His statement reflects SIX’s broader commitment to serving digital asset applications with accurate and regulated market information.

By leveraging DataLink, SIX ensures its data meets the standards of both traditional and decentralized finance.

Furthermore, SIX is a recognized leader in digital asset infrastructure development. The company operates a digital asset central securities depository, known as a CSD.

By connecting to Chainlink’s network, SIX extends its data reach to a far wider audience. This step supports the broader shift toward blockchain-based financial market infrastructure.

New Use Cases Emerge for Tokenized Financial Products

Fernando Vázquez, President of Capital Markets at Chainlink Labs, stated that “Chainlink DataLink provides globally trusted data providers like SIX a secure, scalable path to commercialize high-quality market data onchain.”

He further noted that the platform succeeds in “preserving the integrity, entitlements, and distribution controls required by regulated financial institutions.”

His remarks point to how DataLink is designed specifically for regulated financial environments. This makes it a practical solution for institutions that must comply with strict financial regulations.

The integration enables several new use cases for developers and institutions alike. These include tokenized indices, structured products, and compliant decentralized finance applications.

Prediction markets and new trading primitives can also be built using verified equity data. Each of these use cases relies on high-quality, real-time market information from trusted sources.

Chainlink’s oracle platform currently serves as industry-standard infrastructure across the blockchain space. Its network supports over 2,600 applications operating across more than 75 blockchains worldwide.

This broad reach makes it a practical foundation for publishing regulated financial data. SIX’s integration adds institutional credibility to an already expansive and established network.

As tokenization of real-world assets continues to grow, partnerships like this attract more market attention. Bringing verified equities data onchain removes a long-standing barrier for financial application builders.

Developers can now build products that depend on trusted, regulated market information. This represents a concrete and measurable step in connecting traditional finance with blockchain infrastructure.
