John Procopion

John Procopion has built a career in financial services, specializing in electronic trading and alternative trading systems. He spent nearly nine years at INET ATS, where he headed sales and transactions, before joining Citi's Lava Trading subsidiary. In January 2011, he was promoted to head transaction services at Lava Trading, overseeing the LavaFlow ECN (where he served as President), the smart order router ColorBook, and transaction analytics products. Prior to that, he was responsible for Lava's sell-side execution services business.

At Citi, Procopion led the transformation of multiple alternative trading systems into a single new ATS called Citi-ONE, which was hosted by a third-party provider under Citi's supervision. He also spearheaded Citi's first colocation initiative with Equinix NY4 and achieved approximately two percent market share for LavaFlow ECN. His roles included Director of Cash Trading Electronic Trading (Alternative Trading Systems) from April 2020 onward, and prior to that, Director of Data Governance and Alternative Trading Systems from October 2015 to April 2020.

Unlike his extensive financial career, John Procopion's presence in the poker world is minimal. He has no recorded cashes or appearances in major live tournament databases such as the Hendon Mob, WSOP, or WPT. Based on available information, his poker involvement appears to be purely recreational, with no public tournament results or competitive achievements.

Procopion is based in New York, New York, United States. He holds a Series 24 license as a FINRA Principal/Supervisor. While he has been mentioned in industry publications like Traders Magazine for his professional promotions, he has no known poker-related stories or public image within the poker community.
