IEX Group provides stock trading technology, data, and connectivity to help broker-dealers and investors improve trade execution. It operates the IEX Exchange and uses measures like the Speed Bump—a 38-mile cable that all orders pass through—to reduce speed advantages, along with The Signal, a machine-learning tool that detects price instability, and the Discretionary Peg Order Type (D-Peg) that seeks the midpoint unless The Signal is active. It also offers market data and connectivity services to deliver quote and trade feeds. Revenue comes from trading fees and selling market data and connectivity services, with the aim of helping members achieve more predictable trading results.

What believers are saying

  • IEX holds 6% U.S. exchange market share, up 23% year-over-year.
  • SEC approved U.S. options exchange launch by early 2026.
  • Captured 25% of on-exchange midpoint notional volume in 2025.

What critics are saying

  • MEMX erodes IEX volume with lower latency, gaining high-frequency traders.
  • SEC eliminates speed bump in 2025-01 rule by mid-2027.
  • LTOM by Cboe and MIAX blocks IEX options entry in 2026.

What makes IEX Group unique

  • The Signal employs machine learning to detect unstable stock prices.
  • D-Peg order rests outside NBBO, steps to midpoint unless Signal active.

Swxtch.Io Launches Industrial Internet Of Things Commercial Offering

NEW YORK, June 6, 2023 /PRNewswire/ -- swXtch.io LLC, a wholly owned subsidiary of IEX Group, Inc., today announced the launch of its Internet of Things (IOT) commercial offering for cloudSwXtch. This offering will help companies accelerate digital transformations and migrate high-performance workloads to the cloud, which was not previously possible.cloudSwXtch is an important advancement for the IOT ecosystem as it introduces the ability for users to equip cloud networking stacks with features that are relied on by on-prem workflows. Several top features now accessible with the availability of cloudSwXtch include multicast, high-availability, and Precision Time Protocol (PTP), among others. To illustrate these capabilities, two leading workflows are outlined below, cloud-based audio & video monitoring and virtual test & simulation.Brent Yates, CEO of swXtch.io, commented on the news, "Cloud computing has been a cornerstone of IOT industry growth, driving new heights in asset and operational performance and opening the door to new business models. With cloudSwXtch, no-code multicast enablement is available to network engineers for the first time on all the major clouds."Cloud-Based Audio & Video MonitoringLocal and state governments often rely on large, rugged camera networks to monitor thousands of real-time streams for traffic, emergency management, and other services. These networks overwhelmingly originate and distribute multicast streams, which were previously incompatible with existing cloud networks.cloudSwXtch offers two primary features to support the migration of these video monitoring workflows from on-prem to cloud: the ability to enable multicast traffic distribution from on-prem to edge and cloud environments and the ability to enable bandwidth conservation using the dynamic bridge feature
