Public record / Tickers / ARCI

ARCI — Archimedes Tech SPAC Partners III Co.†

Both disclosure regimes on one name: who in Congress filed about ARCI, which institutions reported holding it. Each section keeps its own clock — congressional trades on the 45-day PTR clock, 13F holdings as quarter-end snapshots.
