Jim Simons's aircraft lands on Long Island the week of a major JPMorgan shake-up

Jim Simons's Gulfstream G800 (N773MJ) was tracked flying a 32-minute hop from Essex County Airport in New Jersey to Republic Airport on Long Island on Thursday evening, June 25. The aircraft climbed to just 5,900 feet, a short hop across the Hudson.

If aboard, Jim Simons would arrive the same week JPMorgan Chase announced a major executive reshuffle, with co-presidents Doug Petno and Troy Rohrbaugh taking over consumer and community banking as Marianne Lake prepares to retire, per American Banker. The flight also coincides with Micron locking in historically high memory prices for five years, as reported by The Register, and IBM unveiling a new chip architecture that could extend Moore's Law, covered by MIT Technology Review. Simons, the Renaissance Technologies founder, has long invested in quantitative finance and tech-adjacent plays; the confluence of banking succession and chip supply deals would make a compelling case for a quiet strategy session.

The aircraft's recent flights show it returned from Italy just hours earlier, touching down in New Jersey after a transatlantic crossing. The quick repositioning to Long Island suggests a tight schedule — possibly a meeting at Renaissance's East Setauket headquarters or with industry contacts in the New York area.
