SIX Group’s exchanges in Switzerland and Spain are now publishing equities market data onchain through Chainlink’s DataLink service, marking another step in the convergence of traditional finance and blockchain infrastructure.
Institutional market data heads onchain
Switzerland’s SIX Swiss Exchange and Spain’s BME Exchange will begin delivering their equities data directly to blockchain networks via Chainlink nodes, according to an announcement on Wednesday.
Data produced by Switzerland’s SIX Swiss Exchange, and Spain’s Bolsas y Mercados Españoles(BME) Exchange, directly to smart contracts as institutional adoption increases.
The integration allows smart contracts to access real-time, institutional-grade market data, something long considered a missing piece for more advanced decentralized finance (DeFi) applications. This gives their developers the access to build new products.
New blockchain-based financial products
With this data now readable onchain, developers can build a wider range of financial products, including tokenized stock indices, structured products, prediction markets, and other DeFi applications.
This development is linked to the wider trend of tokenization, creating digital, blockchain-based representations of tangible assets. Many industry analysts predict that this market could expand into a multi- trillion-dollar market.
Chainlink expands its institutional footprint
The addition of SIX’s exchanges is the latest in a string of high-profile integrations for Chainlink. Other major financial data providers and exchanges already working with the network include Deutsche Börse, FTSE Russell, and S&P Global.
On the crypto-native side, Coinbase is contributing order book and futures data to DataLink. Chainlink is providing low-latency market data for tokenized real-world assets (RWAs), which is expected to reach trillions in value.
A growing push toward trusted onchain data
The integration reflects increasing demand for reliable offchain data sources in blockchain ecosystems, particularly as institutional players explore digital asset markets.
SIX’s head of market data, Matthew Nurse, said the collaboration enables “trusted market data through proven, secure infrastructure,” helping drive innovation across global financial systems.
“Through this integration with Chainlink’s institutional-grade data publishing service, SIX delivers real-time, high-value market data while bringing flagship Swiss and Spanish blue-chip equities on-chain via Chainlink’s DataLink,” Matthew Nurse, said.
SIX’s broader blockchain strategy
SIX has already established a foothold in the digital asset space. The group launched the SIX Digital Exchange in 2020 and has been active in tokenization initiatives, often collaborating with central and commercial banks experimenting with distributed ledger technology.
The two exchanges owned by SIX Group in Switzerland and Spain, together represent about €2 trillion in listed company value, emphasizing the scale of traditional financial assets now beginning to move into the onchain landscape.
Other major European equities brands have inked similar arrangements with Chainlink, including the FTSE Russell, Deutsche Börse and the S&P Global in the U.S. last week.
Reports also show the smaller exchange groups like Boerse Stuttgart Group joining in with their subsidiaries including BX Digital and BX Swiss partnering with Chainlink recently.
DataLink adoption shows momentum
Meanwhile, Coinbase has been supplying trading data to Chainlink Data Link. Chainlink said its DataLink service has already been integrated across thousands of decentralized applications and dozens of blockchain networks since launching last year, indicating the growing traction for institutional-grade data infrastructure in Web3.
SIX Group launched SIX Digital Exchange in 2020, a regulated platform for trading digital assets. Being an “early mover in tokenization” means SIX has been ahead of many traditional players in turning real-world assets (like stocks or bonds) into blockchain-based tokens.
They were also frequent collaborators with both government-run central and commercial banks, an indication of their involvement in institutionalized blockchain projects.
Chainlink also said that DataLink has already been integrated with thousands of dapps and blockchains since their launch.
