A New Model for Market Data Distribution: An Executive Conversation with LMAX

Market data has become one of the fastest-growing costs across financial markets.

Institutions increasingly rely on dozens of proprietary market-data feeds, multiple vendor agreements, and complex licensing models simply to access the prices required to participate in modern markets. As digital assets, tokenized securities, and 24/7 trading environments continue to develop, that complexity is becoming harder to justify.

For David Mercer, CEO of LMAX Group, the next stage of financial-market infrastructure will depend on changing how market data is distributed.

Speaking on The Price of Everything, Mercer reflected on more than three decades in capital markets and the structural changes reshaping the industry. His perspective is grounded in LMAX’s own history: for more than a decade, the company has challenged conventional market structure, from introducing transparent central limit order books in foreign exchange to becoming one of the first institutional crypto exchanges.

That same philosophy led LMAX to become the first FX exchange to contribute data to the Pyth Network.

Today, LMAX continues to publish institutional FX pricing through the Pyth Data Marketplace, alongside data from exchanges, market makers, trading venues, and financial institutions worldwide.

Market data was built for a different era

Traditional market-data infrastructure was designed around exchanges, proprietary terminals, and bilateral distribution agreements.

That model made sense when markets were largely separated by asset class, geography, and trading hours. Institutions accessed equity data through one set of relationships, foreign exchange data through another, and commodities or fixed-income data through additional vendors and specialist systems.

Modern financial markets look very different.

Applications increasingly consume data directly through APIs. Trading systems operate continuously. New financial products combine multiple asset classes. Tokenized assets are beginning to connect traditional financial instruments with digital markets.

The result is a growing demand for access to the “price of everything”: equities, foreign exchange, commodities, crypto, futures, fixed income, and other financial instruments through infrastructure that software can consume directly.

The challenge is no longer simply finding market data. It is distributing that data in a way that is scalable, accessible, and aligned with how modern financial applications are built.

From market-data vendors to market-data infrastructure

Mercer’s view is that the next evolution of finance will come from modernizing the distribution layer.

Institutions closest to price formation should be able to publish directly into infrastructure that allows developers, financial firms, exchanges, and applications to access market data through a common integration.

That approach changes the relationship between data publishers and consumers.

Instead of requiring every application to manage a growing collection of vendor agreements, exchange connections, and licensing arrangements, a unified distribution layer can make institutional pricing available across a broader network of financial software.

For data publishers, the model creates a more direct route to applications and markets. For developers and financial institutions, it reduces operational complexity while preserving the connection to the original source of the data.

This distinction matters. Pyth does not replace the institutions that generate market data. It gives those institutions a modern way to distribute it.

Why LMAX joined early

LMAX became one of the earliest institutional publishers on Pyth because the network’s underlying philosophy closely aligned with its own approach to financial markets.

LMAX was founded on the idea that transparent market access and modern infrastructure can create healthier, more efficient markets. Publishing market data through Pyth represented a natural extension of that approach.

By contributing institutional FX pricing directly to the network, LMAX helps make exchange data available through a unified distribution layer alongside data from other market participants.

That model is increasingly important as financial markets become more connected.

An application building a new financial product may need FX, equities, commodities, crypto, and fixed-income data at the same time. A trading venue operating around the clock may need pricing that reflects markets across different geographies and time zones. A tokenized asset platform may need institutional inputs that can be accessed through software rather than through a traditional terminal.

A single, programmable market-data layer gives these systems a more practical foundation.

The network is expanding across markets

LMAX’s contribution is part of a broader institutional shift.

Pyth’s publisher network now includes a growing roster of exchanges, market makers, trading firms, data providers, and financial institutions. The network supports publishers and applications across equities, foreign exchange, commodities, crypto, futures, and fixed income.

The expansion of the publisher base is matched by the expansion of the markets being served.

As more institutions contribute data, applications can access broader coverage through the same infrastructure. As more applications consume that data, the value of direct, programmable distribution increases for the institutions producing it.

This creates a stronger connection between the supply side and demand side of market data.

For LMAX, the opportunity extends beyond publishing FX prices. It is about helping demonstrate a new model for how financial data can move through the market: directly from institutions, through shared infrastructure, and into the systems building the next generation of finance.

The next decade of market data

Mercer believes the biggest opportunity is still ahead.

Stablecoins, tokenized assets, and programmable financial applications are creating new ways for capital to move and markets to operate. These systems will require trusted pricing across asset classes, geographies, and trading venues.

That requires more than additional feeds.

It requires infrastructure capable of distributing institutional pricing wherever financial applications are built.

LMAX’s early participation in Pyth reflects a broader transition in financial infrastructure. Market data is moving beyond proprietary terminals and fragmented vendor relationships toward a model that is more direct, unified, and designed for software-native finance.

The next generation of capital markets will need market data that can move at the speed of the systems consuming it—built on first-party financial market data and delivered through products like real-time price feeds.

LMAX is helping build that future.
