Chainlink’s DataLink has snagged another data source, this time onboarding the SIX family of Swiss and Spanish stock exchanges to bring their equities market data onchain, according to an announcement on Wednesday.
In particular, data produced by the SIX Swiss Exchange, in Switzerland, and BME (Bolsas y Mercados Españoles) Exchange, in Spain, will be directly legible to smart contracts, enabling developers to build new products like tokenized stock indices, structured products, DeFi applications, prediction markets and other blockchain-based use cases.
This marks the latest big-name get for Chainlink as the need for trustworthy proprietary offchain data sources grows onchain. Tokenization is the umbrella term for building blockchain-based assets that either mirror or officially embody “real-world” equivalents, an activity that some experts figure will become a multi-trillion-dollar market.
“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,” SIX’s head of market data, Matthew Nurse, said. “This enables digital asset applications to access trusted market data through proven, secure infrastructure, fostering trust and innovation across global financial ecosystems.”
The two SIX Group exchanges represent €2 trillion in combined market capitalization. Other major European equities brands have inked similar arrangements with Chainlink, including the FTSE Russell and Deutsche Börse, as well as the S&P Global in the U.S. Last week, BX Digital and BX Swiss, both part of the smaller Boerse Stuttgart Group family of exchanges, partnered with Chainlink.
On the crypto side, Coinbase is feeding DataLink its order book and futures trading information.
SIX is also no stranger to the blockchain, having launched the SIX Digital Exchange in 2020. It was also an early mover in the tokenization space, and is a frequent collaborator with both government-run central banks and commercial banks exploring distributed ledger technology. Aquis Exchange, acquired by SIX in 2025, was not named in the press release seen by The Block.
Chainlink says DataLink has already been integrated with thousands of dapps and dozens of blockchains since launching last year.
