SIX Group has partnered with Chainlink to bring real-time and historical equities market data from its exchanges onchain. SIX Group operates two major European exchanges: SIX Swiss Exchange (Switzerland) and BME Exchange (Spain).
The partnership uses Chainlink’s DataLink, an institutional-grade data publishing service to make equities data directly accessible to smart contracts on blockchain networks. This covers a combined market value of approximately €2 trillion in listed equities, including major blue-chip names like Nestlé, Novartis, Roche (Swiss), and Santander, Inditex (Spanish), plus key indices.
Real-time and historical pricing data for equities and indices listed on these exchanges. The data is now available onchain across 75+ public and private blockchain networks. This is not (yet) full tokenization of the stocks themselves—it’s primarily market data infrastructure. Reliable, regulated onchain data feeds are a foundational step for building things like tokenized equities, onchain derivatives, structured products, or automated trading strategies without relying on offchain oracles that could introduce trust issues.
Traditional finance institutions increasingly need trustworthy data rails to interact with blockchain-based applications. SIX, as a regulated European exchange operator, choosing Chainlink signals growing institutional comfort with decentralized infrastructure for premium market data. This follows Chainlink’s similar deals with other major data providers.

It strengthens Chainlink’s position in bridging traditional capital markets with onchain finance. This is another incremental but meaningful step in bringing high-quality traditional market data onchain, which could accelerate the development of hybrid TradFi-DeFi products in Europe and beyond.
This serves as foundation for tokenized European equities and products — Reliable, regulated real-time + historical pricing data from ~€2T in Swiss and Spanish blue-chip stocks and indices is now directly accessible to smart contracts. This removes a major trust barrier for building tokenized stock indices, structured products, onchain derivatives, and automated strategies without relying on centralized or unverified oracles.
Accelerates RWA adoption in Europe — It bridges traditional capital markets with DeFi and hybrid finance. Developers and institutions can now create compliant onchain applications using premium European market data across 75+ blockchains, potentially unlocking new liquidity and 24/7 use cases for these assets.
Strengthens Chainlink’s dominance in institutional data — This adds another major regulated exchange operator following Deutsche Börse, FTSE Russell, S&P Global, etc. to Chainlink’s DataLink network. It reinforces Chainlink as the go-to infrastructure for high-quality TradFi data onchain, expanding its reach into European equities and supporting broader tokenization efforts.
Signals growing institutional comfort — A regulated European exchange group choosing decentralized oracle rails for its flagship data shows increasing acceptance of blockchain infrastructure by traditional finance players. It lowers technical barriers for other data providers and could encourage more exchanges to follow.
Not full tokenization yet — This is primarily market data infrastructure, not the actual issuance or trading of tokenized shares. However, it’s a critical enabling step—accurate pricing is essential before meaningful onchain equity products can scale with institutional standards.
Overall, it’s an incremental but high-signal move that advances the convergence of TradFi and onchain finance, particularly in Europe. It benefits builders of RWA and DeFi products and bolsters Chainlink’s positioning in the evolving tokenized asset ecosystem.
