## Citadel Securities Urges SEC to Test Smaller Price Increments Before Major Market Overhaul
Citadel Securities is pushing the SEC to adopt a cautious, data-driven approach to market reform, formally requesting a pilot program to test the effects of reducing the minimum price increments—or tick sizes—for certain stocks and ETFs. The move signals a preference for incremental, evidence-based change over sweeping regulatory action, positioning the giant market maker as a key voice in the debate over modernizing U.S. equity market structure.

The proposal, detailed in a letter to the regulator, argues that a controlled pilot is necessary to understand the real-world impact of smaller tick sizes before implementing any broad, permanent changes. This would allow regulators and market participants to assess potential consequences on liquidity, spreads, and market quality without committing to a full-scale overhaul. The request comes amid heightened SEC scrutiny of market practices and follows years of industry debate on whether current tick sizes are optimal for today's high-speed electronic markets.

If adopted, the pilot could delay or reshape more aggressive structural reforms being considered by the SEC. The initiative places Citadel Securities at the center of a critical policy discussion, leveraging its market dominance to advocate for a measured transition. The outcome will influence trading costs, broker profitability, and the competitive landscape for years to come, making this a pivotal moment for U.S. financial market infrastructure.
