Chainlink Disrupts TradFi: Live Data Streams for Tokenized Stocks & ETFs Go Live

Oracle giant Chainlink just pulled the plug on legacy finance's data monopoly—real-time feeds for tokenized U.S. equities are now on-chain.

Wall Street's paper-based system meets its crypto-powered upgrade. No more 15-minute delays, no more opaque pricing—just institutional-grade stock data flowing seamlessly into DeFi protocols.

Tokenized Tesla at T+0 settlement? Check. SPY ETF trades synced to blockchain timestamps? Done. The traditional finance dinosaurs won't know what hit them.

One cynical footnote: Finally, something useful from the tokenization hype—actual infrastructure instead of another 'digital security' whitepaper collecting dust.

• Chainlink Data Streams now provide real-time U.S. equities and ETF data across 37 blockchains.
• Institutional-grade pricing includes market hours logic, staleness detection, and circuit breakers.
• GMX and Kamino integrated the feeds to support tokenized trading, lending and synthetic products.

Chainlink has launched Data Streams for U.S. equities and ETFs, delivering real-time, onchain market data for traditional financial assets. The service delivers high-throughput pricing for traditional financial assets including SPY, CRCL, QQQ, NVDA, AAPL and MSFT.

The feeds deliver real-time market data directly onchain and are currently live across 37 blockchain networks. This enables a new class of tokenized financial products and accelerates the convergence of traditional and decentralized finance.

The company stated that Data Streams are already being adopted by decentralized finance (DeFi) protocols such as GMX, Kamino and GMX-Solana. Chainlink’s Chief Business Officer, Johann Eid, said the release closes a critical gap between traditional finance and blockchain infrastructure, allowing developers to create institutional-grade financial instruments directly onchain.

Institutional-Grade Market Infrastructure for Tokenized Assets

Chainlink’s Data Streams introduce a high-performance data standard that supports tokenized stock trading, synthetic ETFs, and perpetual futures. 

Each data point includes low-latency pricing enriched with metadata such as market hours logic, staleness detection, and circuit-breaker readiness. The company states that this structure helps prevent mispricings, regulatory gaps, and risky liquidations during market disruptions.

Chainlink Data Streams collect inputs from multiple primary and backup data providers, including Finalto, Tiingo and Finnhub, to ensure consistent uptime and accurate pricing. These inputs are then processed through decentralized oracle networks (DONs) and published onchain using a structured data schema.

Jone Zee from GMX Communications states that Data Streams provide the necessary infrastructure to expand perpetual trading and include equities beyond crypto-native assets.

In addition, Kamino Co-Founder Thomas Short highlighted that high-frequency and dependable market data is essential for building secure DeFi lending applications on Solana.

Developers can also use these streams to calculate accurate collateral valuations, develop responsive trading strategies and create arbitrage opportunities based on the differences between tokenized and real-world market prices.

Most existing onchain pricing services offer limited capabilities and often lack the mechanisms required to comply with regulatory and operational standards. The company’s inclusion of market-aware metadata like last update timestamps and open/close status allows protocols to respond to price anomalies or trading halts automatically.

In addition, this launch follows recent U.S. legislative moves like the GENIUS Act which signals growing support for blockchain-based capital markets. Chainlink Labs highlighted that with its battle-tested infrastructure in place, developers and institutions now have the tools required to scale secure and compliant financial products globally.

With greater regulatory clarity in place, TradFi institutions are increasingly engaging with Web3 protocols to access DeFi-native yield.

The launch of Chainlink Data Streams occurs amid rising interest in tokenized real-world assets. According to RWA.xyz, the tokenized RWA market is valued at over $275 billion. With tokenized real-world asset (RWA) markets projected to hit $30 trillion by 2030, this infrastructure is crucial.
