Chainlink Launches Real-Time Onchain U.S. Equity and ETF Data Streams

Chainlink has launched Data Streams for U.S. equities and ETFs, introducing real-time market data directly onchain to support the next generation of tokenized financial products. This service is now available on 37 blockchain networks and supports major assets like SPY, QQQ, NVDA, AAPL, and MSFT [1]. The Data Streams deliver sub-second latency and include metadata such as market status indicators and staleness detection, enhancing the reliability and functionality of decentralized finance (DeFi) protocols [2].

The launch enables developers to create sophisticated onchain products such as tokenized stock trading, perpetual futures, and synthetic ETFs with institutional-grade security. Key features include circuit breaker readiness, end-to-end customization, and the ability to track market hours, ensuring protocols remain secure and functional even during market disruptions [3].

Chainlink’s infrastructure addresses critical challenges in tokenized equity markets, such as mispricing and regulatory risks, by providing comprehensive metadata and context-aware data. This innovation supports the growing demand for tokenized real-world assets (RWAs), a market currently exceeding $275 billion and projected to reach $30 trillion by 2030 [4].

By bridging traditional finance and blockchain, Chainlink Data Streams are accelerating the development of composable financial systems. Partners like GMX and Kamino are leveraging this technology to expand DeFi beyond crypto-native assets and into more sophisticated markets. According to Johann Eid, Chainlink’s Chief Business Officer, this move is a significant leap forward for tokenized markets, closing a critical gap between traditional finance and blockchain infrastructure [5].

The service is designed to scale with future upgrades, including expanded coverage of equities, ETFs, and additional asset classes such as forex and commodities. As institutional interest in tokenized assets grows, Chainlink is positioning itself as a foundational infrastructure provider, enabling secure, reliable, and scalable onchain capital markets [6].
