Market data moves on‑chain

A blockchain is a shared database that multiple computers keep in sync, and Pyth Network says big market-data firms are now using it to distribute prices directly. On April 6, 2026, Pyth said Euronext, Exchange Data International, Fidelity Investments, OTC Markets Group, Singapore Exchange foreign exchange, and Tradeweb had joined as data publishers, and that its Data Marketplace was live. Pyth said those firms had historically distributed data through vendor networks and proprietary terminals, and that the new marketplace lets publishers keep control over access, pricing, and attribution while using one integration to reach applications and blockchains. The data itself is not a crypto token. It is market information such as foreign exchange benchmarks, over-the-counter derivatives prices, exchange-traded fund intraday net asset values, corporate actions, and reference data that software can read automatically. Euronext said on April 10 that it was bringing spot foreign exchange, non-deliverable forward, and precious-metals pricing to Pyth’s network. Tradeweb said it was publishing intraday exchange-traded fund net asset values, known as iNAVs, through the same system. Singapore Exchange foreign exchange said its benchmarks were moving onto Pyth, and Exchange Data International said its corporate-actions data would be available there as well. OTC Markets Group is also publishing over-the-counter equity market data through the network. Pyth has spent several years as an oracle, which is a service that carries outside data into blockchains so smart contracts can use it. Its documentation says its core product delivers deterministic on-chain price feeds, and the marketplace expands that model from simple prices to broader institutional datasets. The company says more than 120 institutions already contribute data to the network, which it says supports more than 3,000 price feeds and has secured more than $3 trillion in cumulative trading volume. Its marketplace page says the distribution layer now reaches more than 100 blockchains. That matters for firms building automated trading and compliance tools because the same signed data can be delivered in a format software can verify and consume without re-keying it from screens or stitching together several vendor feeds. Pyth and Tradeweb both describe the pitch as broader, more programmable access rather than a full replacement for existing channels. The immediate test is whether more incumbent data owners follow these six publishers onto the same rails. If they do, market data may start arriving less like a terminal page and more like an application programming interface that settlement, trading, and reporting systems can use directly.
