Chainlink’s DataLink has integrated equity market data from SIX Group exchanges representing roughly €2 trillion in combined market capitalization. The move expands the availability of regulated financial data onchain, a key input for tokenized asset markets and institutional-grade decentralized finance (DeFi) applications.
The integration includes data from SIX Swiss Exchange in Switzerland and Bolsas y Mercados Españoles (BME) in Spain. Chainlink confirmed Wednesday that these feeds will be accessible to smart contracts, enabling developers to build products tied to real-world equities. Use cases include tokenized indices, structured products, and blockchain-based prediction markets.
Can Equity Data Unlock Tokenized Markets At Scale?
Demand for reliable offchain data has accelerated alongside tokenization efforts across global markets. Tokenized real-world assets are projected by some industry estimates to reach multi-trillion-dollar scale, though adoption remains fragmented. By comparison, total value locked (TVL) across DeFi protocols stands near $90 billion, according to DeFiLlama, highlighting the gap between crypto-native liquidity and traditional market size.
“Through this integration with Chainlink’s institutional-grade data publishing service, SIX delivers real-time, high-value market data,” said Matthew Nurse, Head of Market Data at SIX.
He added that the initiative brings Swiss and Spanish blue-chip equities onchain through secure infrastructure, enabling broader access to trusted financial data.
Chainlink has expanded DataLink aggressively since its launch last year, integrating with thousands of decentralized applications and multiple blockchains. Recent data providers include Coinbase, which contributes order book and futures data, alongside traditional finance entities such as FTSE Russell, Deutsche Börse, and S&P Global. Still, questions remain about how quickly regulated data feeds can translate into meaningful onchain liquidity.
SIX has prior exposure to blockchain infrastructure through its SIX Digital Exchange, launched in 2020, and ongoing collaborations with central and commercial banks. The next catalyst will likely hinge on whether developers convert these new data feeds into scalable financial products with measurable trading volume.
