SIX Group, one of Europe's leading stock exchange operators, has taken a significant step in the blockchain sector. The company is preparing to move stock market data generated through its Swiss-based SIX Swiss Exchange and Spanish-based BME Exchange directly onto the blockchain via the Chainlink infrastructure. This integration makes regulated market data readable by smart contracts, opening up new use cases in tokenization and DeFi. Under the new system, price data from exchanges will be transferred to the blockchain via Chainlink's enterprise data publishing service, DataLink. This will allow developers to directly access real-time and verified market data. This represents a critical infrastructure for many areas, such as tokenized stock indices, structured financial products, decentralized finance applications, and prediction markets. Matthew Nurse, Head of Market Data at SIX, states that the integration brings leading Swiss and Spanish stocks to the blockchain and facilitates access to reliable data sources for digital asset applications.
European stock exchange data is being moved to the blockchain
SIX Group operates as an infrastructure provider in both the Swiss and Spanish financial markets. The company's current data flow; It includes real-time transactions and index data from SWXess and BME trading platforms. With the new collaboration, this data will be transferred directly to the blockchain environment without the need for any additional infrastructure setup.
Chainlink's DataLink service plays a critical role here. The system allows data providers to broadcast from a single point while distributing this data to more than 40 blockchain networks. This allows developers to use the same source without experiencing data incompatibility between different networks.
The scale of the data is also remarkable. According to data released by SIX, the total trading volume on the Swiss and Spanish exchanges reached 154.9 billion Swiss francs in February 2026 alone. Of this, 104.4 billion francs was traded through SIX Swiss Exchange and 55.3 billion euros through BME Exchange. The total market value is estimated to be around 2 trillion euros.
A critical threshold for tokenization
Reliable data flow is essential for creating real financial products on the blockchain. Without price data from traditional markets, it is not possible for tokenized assets to function properly. Therefore, bringing data from regulated exchanges onto the blockchain is a long-awaited development in the industry.
This integration specifically targets four main use cases: tokenized indices requiring real-time prices, structured products needing reference data, DeFi protocols seeking compliant data, and prediction markets requiring accurate settlement data. All of these areas require a data stream that smart contracts can read directly.
The European dimension is also noteworthy. Offering Swiss and Spanish markets through a single data pipeline provides a significant advantage for teams developing products based on multiple markets. At the same time, maintaining data standards under MiFID and MiFIR indicates continuity on the regulatory side.
Chainlink strengthens its role as a bridge
With this collaboration, Chainlink further strengthens its role as a data bridge between traditional finance and blockchain. Due to the technical structures of different blockchains, it is difficult for exchanges to directly publish data; Chainlink translates the data into the appropriate format, transfers it to the chain, and undertakes the verification process.
This model eliminates the need for data providers to build their own blockchain infrastructure. Access to numerous networks becomes possible with a single integration. Security, standardization, and continuity are provided at the middleware layer. Meanwhile, the LINK price is trading at $9.13, down 0.4% in the last 24 hours.
