The Members Exchange, an upstart exchange, is putting its market data on a blockchain network in a nod towards the potential future of how Wall Street accesses its information. The equities exchange is offering free access to its real-time pricing data on the Pyth Network, a distributor of financial market-data that sits on the Solana blockchain. The move will bring MEMX data to new users and is a key step in spurring competition in the space. MEMX’s partnership with Pyth isn’t just about leveraging new tech to distribute data. It’s also about increasing access to market data to a wider swath of users. Market data — which includes everything from the bid and ask price of a particular stock to how much, or little, it is being traded — is the lifeblood of any trading organization. The information is key in helping traders, and their algorithms, make decisions in the market. But access to the data doesn’t come cheap. Global spending on financial market data and analysis totaled $33.2 billion in 2020, a 5.9% year-over-year increase. But despite how crucial market data is to participants, the industry is largely dominated by a handful of players like Bloomberg and Refinitiv.
