The Nasdaq Stock Market LLC filed a proposed rule change with the Securities and Exchange Commission on March 5, 2026, to expand its co-location services into a new expansion area known as NY11-5. This filing, detailed in the Federal Register on March 20, 2026, introduces cabinet offerings, power options, and related services that mirror those in the existing NY11-4 area. The proposal took immediate effect under Section 19(b)(3)(A) of the Securities Exchange Act of 1934, allowing Nasdaq to begin accepting orders ahead of the anticipated first-quarter 2026 opening of NY11-5. This development addresses increasing demand for co-location amid evolving market needs, while ensuring uniform service availability without altering competitive dynamics in securities trading infrastructure.
Background on Nasdaq's Co-Location Services
Co-location refers to the practice where market participants place their servers in the same data center as an exchange's matching engine to reduce latency in trading. Nasdaq's primary data center, NY11, has long offered various cabinet and power options. In recent years, expansions like NY11-4 introduced higher-density power configurations to accommodate advanced computing needs. The current proposal extends these enhancements to NY11-5, part of Nasdaq's ongoing data center growth.
Historically, Nasdaq has filed similar expansions under SEC oversight to comply with the Exchange Act's requirements for fair access and competition. For instance, prior filings, such as those related to NY11-4, emphasized voluntary participation and non-discriminatory offerings. This latest change builds on that framework, responding to capacity constraints in existing areas. Key players include Nasdaq as the self-regulatory organization, the SEC as the approving body, and co-location customers such as high-frequency trading firms, brokers, and vendors who rely on these services for efficient market access.
Key Components of the Proposed Rule Change
The filing proposes introducing a standardized cabinet option in NY11-5, identical to that in NY11-4, designed to support uniform cooling, power distribution, and structural loads. Nasdaq notes that it does not allow customer-provided cabinets to maintain consistency across the data center.
Additionally, five power options currently exclusive to NY11-4 will be available in NY11-5: Phase 1 20 amp 240 volt, Phase 1 32 amp 240 volt, Phase 1 40 amp 240 volt, Phase 3 20 amp 415 volt, and Phase 3 32 amp 415 volt. These options cater to varying capacity needs, with Phase 3 providing greater power density through three-wire delivery compared to Phase 1's single-wire setup. Nasdaq asserts that these are not inherently superior to NY11's options, as customer preferences depend on specific requirements.
The proposal also extends power distribution units (PDUs) to NY11-5, including Phase 1, Phase 3, and a switch-monitored add-on for remote control. PDUs are optional, allowing customers to supply their own if preferred. Fees for all NY11-5 services remain to be filed separately, with placeholders like 'TBD' in the rule text indicating future determinations.
Nasdaq justifies these changes under Section 6(b)(5) of the Exchange Act, stating they promote just and equitable trade principles by enhancing customer choice without unfair discrimination. The filing emphasizes that services are voluntary and available on equal terms.
Legal and Regulatory Context
This proposal aligns with precedents in SEC approvals of co-location expansions. For example, in Securities Exchange Act Release No. 34-101078 (September 18, 2024), Nasdaq addressed equalization of cross-connects across its data center, though the current filing explicitly excludes such network-related changes. The immediate effectiveness under Rule 19b-4(f)(6) reflects the SEC's view that the change does not significantly affect investor protection or competition, with a 60-day window for potential suspension.
Politically, such filings occur amid broader debates on market infrastructure fairness. Critics, including some investor advocacy groups, argue that co-location advantages high-speed traders, potentially disadvantaging retail investors. Supporters, like industry associations, highlight efficiency gains for the national market system. Nasdaq's filing counters burden-on-competition concerns by noting alternatives, such as indirect co-location through vendors or opting out entirely.
Implications and Perspectives
In the short term, this expansion could alleviate space constraints in NY11 and NY11-4, enabling more participants to access low-latency services as trading volumes grow. Long-term, it may influence market structure by standardizing offerings across Nasdaq's facilities, potentially setting a model for other exchanges like NYSE or Cboe.
Different perspectives emerge: proponents see it as a necessary adaptation to technological demands, fostering innovation. Opponents worry about entrenching advantages for well-resourced firms, though Nasdaq's filing asserts no undue burden on competition. Regulators, via the SEC, balance these views by ensuring compliance with the Exchange Act's anti-discrimination provisions.
The proposal's scope is limited to physical infrastructure, avoiding latency-sensitive elements like the ongoing Equalization Project.
In summary, Nasdaq's expansion into NY11-5 extends established services to meet demand, with implementation slated for early 2026. Potential next steps include the SEC's review period and Nasdaq's fee filing. Ongoing debates may focus on equitable access, while challenges could arise from capacity planning or regulatory scrutiny. This development underscores the evolving intersection of technology and regulation in securities markets.
