April 16, 2026 – A landmark deal between SIX Group and Chainlink Labs puts real-time Swiss and Spanish equity data on more than 75 blockchains. It marks a new frontier for tokenized capital markets.
In Summary
SIX Group and Chainlink went live on April 15, 2026, with a first-of-its-kind integration.
Equity data from SIX Swiss Exchange and BME Exchange worth over €2 trillion is now accessible on-chain.
Data flows via Chainlink DataLink to 2,600+ applications across 75+ blockchains.
New use cases include tokenized indices, compliant DeFi, structured products, and prediction markets.
The move arrives as the global tokenized RWA market surpassed $27 billion in April 2026 up 4× year-over-year.
McKinsey projects the RWA market could reach $2 trillion by 2030, with equities as a key growth driver.
The Deal at a Glance
SIX Group and Chainlink Labs announced a major integration on April 15, 2026. It delivers on-chain equity market data from Switzerland and Spain. The combined value of listed equities covered is over €2 trillion.
The data flows through Chainlink DataLink. That is an institutional-grade publishing service. It uses the Chainlink data standard for secure delivery. The integration is live for the first time.
SIX operates both the Swiss Exchange (SIX Swiss Exchange) and Spain’s BME Exchange. Together, those venues list some of Europe’s most traded blue-chip stocks. Connecting their data to blockchain applications is a first for European market infrastructure.
How DataLink Works
Chainlink’s DataLink gives data providers a configurable distribution layer. Publishers maintain full control over access rights and entitlements. They integrate once but reach every connected network. No custom blockchain development is required.
“SIX delivers real-time, high-value market data while bringing flagship Swiss and Spanish blue-chip equities onchain via Chainlink’s DataLink.”
— Matthew Nurse, Head Market Data, SIX Group
Why This Matters: The RWA Surge
This deal lands at a pivotal moment. The tokenized real-world asset (RWA) market surged past $27 billion in April 2026. That is a fourfold jump versus just one year ago. Tokenized equities remain a smaller slice. But they are among the fastest-growing categories.
For context, McKinsey projects the RWA market could reach $2 trillion by 2030. Equity tokenization is expected to be a key driver. This SIX–Chainlink integration directly positions European equities inside that growth trajectory.
New Use Cases Unlocked
Real-time equity data onchain opens several categories of new applications. Here are the most significant ones enabled by this integration.
About the Partners
SIX is owned by around 120 financial institutions. It has over 4,300 employees across 19 countries. In 2025, it generated CHF 1.7 billion in operating income and CHF 460 million in EBITDA. It already operates a digital asset central securities depository (CSD). That makes it a rare exchange operator with both traditional and digital infrastructure.
Chainlink’s ecosystem connects over 2,600 projects. These range from early-stage DeFi protocols to large financial institutions. The network has enabled tens of trillions of dollars in total transaction value. Major adopters include Swift, Euroclear, Mastercard, UBS, and Fidelity International.
“Chainlink DataLink provides a secure, scalable path to commercialize high-quality market data onchain while preserving integrity, entitlements, and distribution controls.”

The Bottom Line
This is not a pilot program. Live equity data from two major European exchanges is now flowing onchain. The infrastructure is already in place. The use cases are real. And the timing is perfect, the RWA market is growing at its fastest pace yet. Watch for adoption by DeFi protocols over the next two quarters.
