Two of Europe’s largest stock exchanges, operated by SIX Group, are pushing their equity market data directly onto blockchain networks via Chainlink, in a move that deepens the connection between traditional markets and decentralized finance.
The SIX Swiss Exchange and Spain’s Bolsas y Mercados Españoles (BME), which together represent roughly €2 trillion in combined market capitalization, are now feeding pricing and trading data into Chainlink’s DataLink service. That data becomes available for use in decentralized applications (dapps) across multiple blockchains.
What the integration enables
Through the Chainlink link-up, real-time, verified equity data from the Swiss and Spanish markets can be used to power a range of on-chain financial products, including:
- tokenized indices
- prediction markets
- structured financial contracts and derivatives
The arrangement is designed to provide “institutional-grade” price and trading information on-chain, allowing developers to build more complex and reliable financial tools that reference traditional securities.
Nurse, head of market data at SIX, said the collaboration ensures high-value data from both exchanges is available on-chain in real time. SIX previously launched the SIX Digital Exchange in 2020 to support trading and settlement of digital assets, and has since been active in tokenization and distributed ledger pilots with central banks and financial institutions.
Part of a broader data-on-chain trend
The SIX–Chainlink initiative comes amid a wider shift by major financial data providers to broadcast market information to blockchain networks.
Similar data distribution arrangements have been announced by:
- Deutsche Börse
- FTSE Russell
- S&P Global
Last week, BX Digital and BX Swiss, both part of the Boerse Stuttgart Group, also entered comparable partnerships with Chainlink to make their market data accessible to dapps.
According to earlier disclosures, pricing information from the Swiss and Spanish exchanges accounted for a combined trading turnover of CHF 195.4 billion in March 2026. The market capitalization of the Swiss exchange alone was about $2.4 trillion in February 2026, highlighting the scale of data now being made available on-chain.
Chainlink’s growing data infrastructure
Chainlink said its DataLink implementation, launched last year, has been adopted by thousands of decentralized applications running across multiple blockchains. On the crypto side, trading data from major digital asset platforms has also been integrated into the network.
More broadly, Chainlink reports that its oracle infrastructure has secured tens of billions of dollars in on-chain value and has processed more than $29 trillion in transaction volume since inception, underscoring demand for trusted off-chain data in decentralized systems.
SIX’s long-term blockchain strategy
SIX has built up substantial experience with distributed ledger technology, running tokenization pilots with central banks and major financial firms. Its acquisition of Aquis Exchange in 2025, while not mentioned in the current announcement, fits into a broader strategy of engaging with new market infrastructure.
The latest collaboration signals continued commitment to integrating traditional capital markets with blockchain-based platforms, as 2026 shapes up to be a year of accelerated convergence between established exchanges and on-chain financial architecture.
Market context and asset price dynamics
For traders in digital asset markets, the expanding flow of traditional market data into blockchain networks is seen as a key building block for the next generation of financial products, from fully on-chain structured notes to regulated tokenized securities.
Chainlink’s underlying network has recently shown a 15% increase in active addresses over the past week, even as its native token’s price has remained constrained. The asset has traded in a narrow band between $8.20 and $9.55 since February, with low volatility and falling volumes.
Analysts note that this extended price compression coincides with technical patterns such as a large-scale falling wedge, which are often associated with potential breakouts after prolonged consolidation. Some market observers view the divergence between rising network usage and muted price action as a possible precursor to a more decisive move once the current range resolves.
