Current Position
Justin Schack is Head of Market Structure at Rosenblatt Securities.
Background & Biography
The firm’s public team biography states that he joined in 2008 after twelve years covering market-structure transformation at Institutional Investor. His professional background combines financial journalism with analysis of the organisation of trading markets. Rosenblatt’s New York operating address provides the basis for the United States designation, rather than an inference about personal nationality.
The firm describes its market-structure practice as examining trading volumes, venues, order types and changes in North American and European markets. Schack leads that practice, but leadership of the team does not establish personal authorship of every report or responsibility for every conclusion it publishes.
Notable Contributions
Rosenblatt’s public 2025 Global Exchange Leader Conference agenda lists Schack as moderator of its US market-structure and regulation panel. The published scope expressly includes equity tokenisation and overnight trading alongside conventional market-regulation questions. That is a documented connection between his market-infrastructure work and debates about digital representations of securities.
The agenda supports the description of a public programme role, not a claim that he developed a tokenisation platform, implemented a regulatory change or endorsed every idea discussed by other participants. His current team biography also identifies conference speaking as part of his professional activity.
Why Katharos.ai Is Following Them
Katharos.ai is following Schack for the connection between established trading-market structures and proposals to change how securities are represented and traded. Tokenisation raises questions about execution, liquidity and the interaction of new and existing venues. A market-structure perspective can help separate technological proposals from the practical requirements of operating markets. Inclusion here is based on that specific professional relevance, not a general finance title alone.
Areas to Follow
Areas to follow include public commentary on tokenised equities, overnight or continuous trading and the interaction between trading venues and market rules. Future coverage will identify the publication date and context of particular positions, distinguish a conference topic from a personal conclusion, and check any changes to his professional responsibilities.
Reporting Scope
Coverage is confined to permitted public professional information and identifiable public contributions. This profile does not reproduce Rosenblatt’s signed-in Workspaces research, disclose confidential clients or attribute team-wide findings without an authorship source. It is not investment advice or an endorsement of any proposed market model.
