Plutonian Acquisition Corp. II, trading under the ticker PLUN-UN, filed a Form 8-A12B with the SEC on April 27, 2026, registering its units for listing on a national securities exchange — a step that marks the formal commencement of the blank-check company's public trading life. The "II" designation indicates this is a follow-on vehicle from the same sponsor group behind the original Plutonian Acquisition Corp., though sponsor entity details are pending public disclosure. The SPAC completed its IPO in 2026 and is currently in the search phase, seeking a merger target across a yet-to-be-specified industry vertical.
