TL;DR
- Pyth Network adds Fenics Market Data, OpenYield, and Tradeweb as institutional fixed income data providers.
- Fenics contributes executable prices from over $1 trillion in daily OTC volume; Tradeweb distributes benchmark closing prices for government bonds.
- OpenYield is an SEC-registered alternative trading system that provides quotes on Treasuries, corporates, and municipals.
The Pyth network added three new top-tier data providers: Fenics Market Data, the data distribution arm of BGC Group (Nasdaq: BGC); OpenYield, the automated bond marketplace; and Tradeweb Markets Inc. (Nasdaq: TW), one of the world’s leading electronic fixed income platforms. All three will begin publishing institutional fixed income prices on Pyth Pro and the Pyth Data Marketplace through a single integration.
The addition covers three distinct market segments. Fenics contributes executable prices sourced from OTC transactions between dealers, with daily volume exceeding $1 trillion across rates, credit, currencies, commodities, and energy. OpenYield, registered as an Alternative Trading System with the SEC, provides firm and executable quotes on Treasuries, corporate bonds, and municipals, derived directly from its order book.

Tradeweb, for its part, distributes the Tradeweb FTSE Benchmark Closing Prices, the official closing prices for government bonds —UK Gilts, US Treasuries, and European sovereign bonds— administered by FTSE Russell and used as a reference in the FTSE World Government Bond Index.
Pyth: Why Fixed Income and Why Now
The fixed income market surpasses the equity market in size in most developed economies. Yet its prices have historically been costly, fragmented, and difficult to integrate into modern systems. A significant portion of trading occurs bilaterally between banks and dealers, outside the public order books of traditional exchanges.
Mike Cahill, CEO of Douro Labs and contributor to Pyth Network, noted that “making fixed income available through the same infrastructure that already distributes equities, futures, currencies, and commodities is a structural step toward a modern and unified market data standard”.
This addition is part of a long-term institutional expansion process. Fidelity Investments, Kalshi, and Euronext FX recently joined the network, which already spans currencies, precious metals, ETFs, derivatives, and prediction markets. With the three new fixed income providers, Pyth will strengthen its position as a distribution layer for the institutions closest to price formation in global markets.
