Chainlink has launched real-time data streams for U.S. stocks and ETFs, connecting Wall Street to decentralized finance (DeFi). With coverage across 37 blockchains, this innovation allows traditional financial markets to interact with Web3, unlocking new possibilities for tokenized assets and synthetic products.
Real-time market data now on-chain
The new Data Streams provide live price feeds for leading U.S. stocks such as Apple (AAPL), Microsoft (MSFT), and Nvidia (NVDA), along with ETFs like SPY and QQQ.
Key features include:
- Timestamped and verified data to avoid stale executions.
- Market status flags and circuit breakers, mirroring protections from traditional exchanges.
- Ultra-low latency, ideal for tokenized trading and on-chain derivatives.
DeFi protocols including GMX, Kamino Finance, and GMX‑Solana have already begun integration, enabling synthetic ETFs, collateralized lending with real stocks, and tokenization of real-world assets (RWAs).
Competing oracle solutions
While Chainlink leads the market, other oracle platforms are entering the space:
- Pyth Network streams real-time prices for U.S. and Hong Kong stocks plus 100+ ETFs, with updates every 400 ms and deployment across 40+ blockchains.
- RedStone Finance focuses on DeFi lending and RWAs, delivering real-time liquidation data with lower gas costs.
- Band Protocol and UMA operate in niche oracle use cases, with more limited equities coverage.
Despite the competition, Chainlink remains the dominant multi-chain oracle for equities data, providing institutional-grade reliability for DeFi integrations.
Why this matters for the future of DeFi
Bringing real-time equity data on-chain opens doors for:
- Mass tokenization of real-world assets (RWAs), creating new investment opportunities.
- Synthetic and derivative products on-chain, replicating traditional markets with 24/7 liquidity.
- Collateralized lending with stocks and ETFs, merging traditional finance with Web3.
Experts see this as a key step toward global financial convergence, creating a continuous and borderless market for tokenized assets.
