US Stock Data Goes Onchain as Chainlink Launches Real-Time Feeds for ETFs and Equities on 37 Blockchains

Chainlink’s New Data Streams Bring Real-Time US Stock Prices Directly Onchain

Chainlink has launched a product called Data Streams, which delivers live, low-latency pricing for major US equities and ETFs directly onto blockchain networks.

Covering popular assets such as SPY, QQQ, Nvidia, Apple, and Microsoft, this service is now active across 37 blockchains, enabling fresh possibilities for tokenised stock trading, synthetic ETFs, and perpetual futures.

How Does Data Streams Work?

Data Streams pull real-time market data from multiple primary and backup sources to guarantee consistent uptime.

The feeds are processed via Chainlink’s decentralised oracle networks and supplied onchain in a structured format, with every data point timestamped.

This allows smart contracts and DeFi platforms to distinguish between current and outdated prices, enabling features like automatic trading pauses when markets close — similar to safeguards used on traditional exchanges.

By ensuring reliable, continuous data flow, Chainlink’s product supports sophisticated financial tools such as lending platforms, synthetic asset creation, and perpetual contracts.

This infrastructure aims to bring the precision and trust required in conventional capital markets into the blockchain ecosystem.

Major DeFi Players Adopt Data Streams as Tokenised Markets Expand

Top decentralised finance projects like GMX and Kamino Finance have already integrated Data Streams.

Johann Eid, Chainlink’s Chief Business Officer, said:

“This is a significant leap forward for tokenised markets—closing a critical gap between traditional finance and blockchain infrastructure.”

Thomas Short, co-founder of Kamino Finance, explained that the launch represents a step toward “a truly composable onchain financial system that matches the scale and sophistication of traditional markets.”

GMX’s communications lead Jone Zee added that the feeds unlock new trading opportunities while enhancing platform security and user trust.

Why Onchain Pricing for Equities Could Change Finance?

Tokenised real-world assets (RWA) markets are estimated to be worth around $275 billion today, with forecasts suggesting growth to $30 trillion by 2030.

This massive expansion demands secure, high-performance infrastructure capable of delivering market data with institutional-level reliability.

Chainlink’s Data Streams bring capital markets data directly onto blockchains, making it possible to build products previously limited to traditional finance.

New US legislation like the GENIUS Act signals growing regulatory acceptance of blockchain’s role in capital markets.

Institutions such as BlackRock and JPMorgan are increasingly interested in tokenising bonds, funds, and real estate.

Chainlink’s service addresses the longstanding challenge of providing dependable, real-time pricing essential for settlement, compliance, and risk management.

Bringing Wall Street Data to DeFi Without Compromise

Data Streams offer more than just prices.

They include features to detect stale data and enable circuit breakers to prevent errant trades during off-hours, closely mirroring mechanisms used in traditional exchanges.

This kind of context-aware, high-frequency pricing from premium sources ensures DeFi products can operate with the same reliability as conventional markets.

Kamino Finance highlighted how Data Streams allow them to build “a seamless user experience without compromising on security or trust.”

This is crucial for expanding tokenised equities into lending, borrowing, and trading on platforms like Solana and beyond.

What Will Tokenised Markets Look Like When Real-Time Data Goes Onchain?

Chainlink's Data Streams have the potential to fundamentally change how financial products are built and traded.

By making live, trusted market data universally accessible onblockchain, tokenised assets may finally achieve the scale and complexity needed to attract broader institutional participation.

This raises questions about how regulation, market dynamics, and technology will evolve together.

Could tokenised stocks and ETFs traded on decentralised platforms challenge traditional exchanges?

Will these innovations create a new, more transparent era of finance, or add fresh complexity?

As more capital markets data moves onchain, the line between legacy finance and DeFi continues to blur, inviting developers and investors alike to rethink what the future of markets might become.
