What MEMX does

MEMX is a member-owned U.S. securities exchange operator and exchange technology provider founded in 2019 and headquartered in New York. The company operates three SEC-registered exchanges: the MEMX Equities Exchange (launched September 21, 2020), the MEMX Options Exchange (launched September 2023), and MX2 Options (a pro-rata options exchange scheduled to launch in Q2 2026). MEMX serves a member base of 64+ trading firms spanning banks, market makers, retail brokers, and institutional investors, with total U.S. equity market share reaching 4.2% by December 2021 and growing in options to 4.1% total share by July 2025. The company also offers MEMX Market Technology, a white-label "market-as-a-service" platform that powers five external market centers including Long-Term Stock Exchange, 24X Exchange, Blue Ocean Technologies, and InPlay Global.

MEMX's core technology is a proprietary, high-performance, low-latency, deterministic multi-asset-class trading platform built on interoperable components that can be configured to support equities, options, and novel market models. The infrastructure uses 25 Gigabit Ethernet connectivity, supports advanced order types, active real-time risk controls, and direct market data feeds, and targets 99.9%+ uptime. A wholly-owned routing broker-dealer subsidiary, MEMX Execution Services, LLC (FINRA-registered), handles Reg NMS routing obligations.

The company generates revenue through three streams: maker/taker transaction fees on its U.S. Equities and U.S. Options exchanges (with a Displayed Liquidity Incentive rebate program), market data subscription fees (Top of Book, Last Sale, Depth of Book priced at least 25% below comparable exchanges), and technology licensing royalties from third-party market center clients. Pricing is transaction-based for exchange members and subscription-based for market data, with no minimum fee tiers on the exchange. The company's go-to-market is enterprise sales for both the membership model and the Market Technology platform, supported by content marketing, the Member Voices video series, industry conferences, and market structure advocacy (including white papers on tick size and round lot reform).

Scale indicators9 records

Expansion highlights6 records

Broad incumbents

• Intercontinental Exchange (NYSE): ICE owns the New York Stock Exchange and operates multiple US equity exchanges. It is a major incumbent competitor in MEMX's core equities market and operates its own market data and technology businesses at significantly larger scale.
• Cboe Global Markets: Cboe is the dominant US options exchange operator and a major equities exchange. It offers overlapping capabilities including options (MEMX Options competes directly), equities, market data, and BIDS trading technology. Much larger scale but a key direct competitor for MEMX's options and equities volumes.
• Nasdaq, Inc. Nasdaq operates one of the largest US equity exchanges plus options, Nordic exchanges, and a broad market technology business (Nasdaq Marketplace Services). Comparable as a US equity/options incumbent and a competitor/partner for exchange technology licensing.

Regional players

• Deutsche Börse: Deutsche Börse operates the Frankfurt Stock Exchange and Eurex derivatives exchange, plus market data and technology services. Comparable on exchange operations and technology infrastructure but focused on European markets.
• London Stock Exchange Group (LSEG): LSEG operates the London Stock Exchange plus FTSE Russell, Refinitiv data, and post-trade infrastructure. Comparable on multi-asset exchange operations and a market data franchise, but UK-headquartered with a focus on European and global markets.
• TMX Group: TMX operates the Toronto Stock Exchange and other Canadian marketplaces plus an analytics business. Comparable as a multi-asset exchange operator with technology licensing ambitions, but primarily serves Canadian markets rather than the US.
• Euronext: Euronext operates multiple European equities and derivatives exchanges and offers trading technology services. Comparable as a multi-asset exchange operator with technology licensing, but serves European rather than US markets.

Direct peers

• Miami International Holdings (MIAX): MIAX operates a vertically integrated multi-asset exchange complex (equities, options, futures) and licenses its trading technology to other exchanges globally via the MIAX Emerald/Sapphire platforms. Highly comparable on both exchange operations and exchange-tech-as-a-service dimensions.
• BOX Options Exchange: BOX is a US options exchange with a unique price-improvement auction mechanism and a smaller market share profile similar to MEMX Options. Comparable as a focused options exchange operator competing for liquidity in the same US options market.
• Investors Exchange (IEX): IEX is a US equities exchange operator founded with a similar member-aligned mission and competing on speed-of-light parity, fee transparency, and broker-dealer-friendly economics. It is the closest direct comparable in scale and positioning to MEMX.
