Overview

Spread Networks is a specialized telecommunications and network-infrastructure company associated with one of the most prominent low-latency connectivity projects in electronic finance. Its principal network links the Chicago financial market, including the Chicago Mercantile Exchange area, with the New York metropolitan market, including the Nasdaq data-center area in Carteret, New Jersey. The service was designed primarily for financial firms, especially high-frequency trading businesses, for which a difference of fractions of a millisecond can affect the order in which market data is received and trades are executed. The business originated from a market-structure problem identified by founder Dan Spivey. In 2007, while working on an arbitrage strategy involving discrepancies between Chicago futures and related equities traded in New York, Spivey encountered the practical limits of existing network connections. The strategy could be designed successfully, but access to the fastest available communications path was unavailable or insufficient. He therefore investigated whether a purpose-built route could reduce the distance and latency between the two markets. James L. Barksdale, the former Netscape chief executive, backed the project financially. Spread Networks constructed an approximately 827-mile, or 1,331-kilometre, fiber-optic route between the Chicago area and Carteret, New Jersey. The route was engineered to be as geographically direct as practical, reducing the distance traveled by signals compared with conventional paths. Construction was reportedly carried out with a high degree of secrecy during its early stages so that competing network providers would not learn the plan before the line was ready. The project cost approximately $300 million according to the cited reference material, although that figure is a historical project-cost estimate rather than a current financial disclosure. The first line was unveiled in June 2010. Spread Networks marketed both dark-fiber access and managed wavelength services, alongside colocation or related facilities at locations along the route. Its connectivity was intended to provide low latency, high bandwidth, and high reliability. The company reported an estimated round-trip latency of about 13 milliseconds for its Chicago-to-Carteret dark-fiber path. Its wave services were somewhat slower, with reported round-trip times of roughly 14.1 to 14.2 milliseconds after improvements from earlier performance levels. The network’s commercial importance came from the economics of electronic trading rather than from mass-market internet access. A low-latency connection can allow a trading firm to receive price information or submit an order slightly earlier than a rival using a longer route. Spread Networks therefore became a frequently cited example of how financial-market competition had turned physical geography, fiber routing, data-center location, and signal propagation into strategic business assets. The project also attracted wider public attention through discussion of high-frequency trading, including coverage in Michael Lewis’s book Flash Boys: A Wall Street Revolt. After launching the core route, Spread Networks expanded its New Jersey presence. In 2011 it added connectivity or network locations at Equinix NY4 in Secaucus, 300 Boulevard East in Weehawken, and 165 Halsey Street in Newark. In October 2012 the company announced a latency improvement that reduced estimated round-trip time from 13.1 milliseconds to 12.98 milliseconds. In January 2014 it announced a point of presence at the NYSE Euronext trading center in Mahwah, New Jersey. On November 27, 2017, Zayo Group Holdings announced a definitive agreement to acquire Spread Networks for $127 million in cash. The acquisition placed the network within Zayo’s broader communications-infrastructure portfolio.

History

Spread Networks emerged from the convergence of electronic trading and specialized communications infrastructure. Its founder, Dan Spivey, identified the opportunity in 2007 while developing an arbitrage strategy based on relationships between futures contracts traded in Chicago and underlying equities traded in New York. The strategy depended on receiving market information and transmitting orders quickly, but the available communications paths did not provide the lowest latency required for practical execution. Spivey consequently explored the feasibility of building a dedicated route and obtained financial backing from James L. Barksdale, formerly the chief executive of Netscape. The resulting project focused on a direct fiber-optic connection between the Chicago area and Carteret, New Jersey. Chicago was important because of its derivatives markets, particularly the Chicago Mercantile Exchange, while Carteret hosted a major Nasdaq data-center location. Rather than relying on an ordinary telecommunications route, Spread Networks designed an approximately 827-mile path intended to follow the shortest practical geography. The project reportedly cost about $300 million. Construction was conducted discreetly during its early phase, reflecting the commercial sensitivity of being first to offer a new low-latency route to financial firms. The initial line was unveiled in June 2010. Spread Networks offered dark fiber, allowing customers to control or dedicate their own optical equipment, as well as wavelength-based services. The network was promoted on three principal attributes: reduced latency, substantial bandwidth, and operational reliability. The company described continuous monitoring and regular testing of the route as part of its reliability approach. It also offered colocation or related server-access facilities in Chicago, Carteret, and Cleveland. The reported dark-fiber round-trip time between Chicago and Carteret was approximately 13 milliseconds. That represented a modest improvement over conventional fiber routes, but the difference had commercial value for high-frequency trading firms competing to act on market information. The network became emblematic of the physical infrastructure race surrounding electronic markets. Its business model showed that a communications company could monetize a very small speed advantage when customers traded large volumes in highly competitive markets. Spread Networks expanded its access points in 2011, adding locations at Equinix NY4 in Secaucus, 300 Boulevard East in Weehawken, and 165 Halsey Street in Newark. In October 2012 it announced that engineering or operational improvements had reduced estimated round-trip latency from 13.1 milliseconds to 12.98 milliseconds. In January 2014 it announced a point of presence at the NYSE Euronext trading center in Mahwah, extending its reach to another important trading location. The company’s technology also formed part of a broader debate about the limits of fiber optics. Because light travels more slowly through glass than through air, some competitors pursued microwave or other air-based transmission systems that could produce lower latency on suitable routes. Companies cited in discussions of the sector included McKay Brothers, Metrorede, and Tradeworx. Spread Networks nevertheless remained a prominent example of a purpose-built fiber route and of the infrastructure economics of high-frequency trading. The network received broader public exposure through writing about automated and high-frequency trading, including Michael Lewis’s Flash Boys: A Wall Street Revolt. This attention made Spread Networks recognizable beyond the telecommunications industry, although its customer base remained primarily institutional and financial rather than consumer-oriented. On November 27, 2017, Zayo Group Holdings announced a definitive agreement to buy Spread Networks for $127 million in cash. The transaction represented a strategic fit with Zayo’s portfolio of fiber and communications assets. The supplied reference material does not provide a later standalone operating history, named post-acquisition executives, or confirmation of the current status of the Spread Networks brand. Accordingly, the company’s post-acquisition identity is recorded conservatively.
