Chainlink Launches Real-Time U.S. Equities and ETF Data Streams for Onchain Finance

Chainlink has launched real-time data streams for U.S. equities and ETFs, representing a major advancement in integrating traditional financial assets with blockchain-based systems. The new feature provides onchain access to high-frequency, high-throughput pricing for major assets such as SPY, QQQ, NVDA, AAPL, and MSFT. Available across 37 blockchain networks, this initiative is already being adopted by DeFi protocols including GMX and Kamino [1]. It aims to support the development of tokenized financial products such as perpetual futures, synthetic ETFs, and tokenized stock lending [1].

This development is positioned as a critical step in expanding decentralized finance (DeFi) into broader capital markets. The tokenized real-world assets (RWA) market, currently valued at over $275 billion, is expected to reach $30 trillion by 2030 [1]. The lack of reliable onchain infrastructure for U.S. equities has been a major barrier to progress, but Chainlink’s solution introduces context-aware data features such as market hours tracking, stale price detection, and circuit breaker readiness, all essential for institutional-grade tokenized equity products [1].

The technology behind Chainlink Data Streams ensures data reliability and accuracy by aggregating inputs from multiple primary and backup sources via decentralized oracle networks (DONs) and delivering them via a structured schema onchain [1]. This allows smart contracts to assess the freshness and relevance of data in real time, preventing mispricings and unfair liquidations. For instance, the inclusion of a lastUpdateTimestamp enables protocols to determine whether the data is safe to use, especially during market disruptions like trading halts [1].

Key use cases enabled by these data streams include tokenized stock lending, perpetual trading on U.S. equities, and the creation of synthetic ETFs with transparent composition [1]. DeFi platforms can now integrate real-time market metadata to develop more sophisticated risk management systems and arbitrage strategies. The distinction between real-world prices and tokenized stock prices onchain opens up opportunities to capture price spreads and manage risk more effectively [1].

The timing of this launch aligns with broader regulatory and market developments, including the proposed GENIUS Act, which signals increasing institutional interest in blockchain-based financial infrastructure [1]. With DeFi protocols now able to access institutional-grade data for U.S. equities and ETFs, the traditional finance and onchain markets are becoming more integrated [1].

Chainlink’s infrastructure, which already secures over $25 billion in DeFi total value locked (TVL), is now extending its influence into capital markets, reinforcing its role as a foundational layer for global financial innovation [2]. By offering reliable, secure, and context-rich data streams, Chainlink is enabling developers to build advanced financial products with the transparency and integrity typical of traditional markets [1].

Looking ahead, Chainlink plans to expand the coverage of equities and ETFs, support additional asset classes such as forex and commodities, and integrate more contextual data to enhance protocol functionality [1]. These upgrades reflect the company’s commitment to scaling onchain capital markets and supporting the next phase of DeFi evolution.

This launch represents a major milestone in the tokenization of real-world assets and underscores Chainlink’s leadership in advancing institutional-grade onchain finance [1].
