Another Trump political opponent federally charged by May 31?

Platform comparison

Market context

The market is pricing zero probability that federal prosecutors will charge any individual who previously investigated, prosecuted, or oversaw criminal cases against Donald Trump between now and May 2026. This covers special counsel Jack Smith, DOJ officials involved in the classified documents or January 6th investigations, state attorneys general who pursued cases, and any current or former investigators in those matters. The settlement window captures roughly eighteen months from typical market creation.

Historical precedent offers limited guidance. Post-Watergate, no prosecutor or investigator of a sitting president faced federal charges during the subsequent administration, though several faced civil suits and professional discipline. The Reagan era saw no federal charges against Carter-era investigators despite partisan tensions. However, the Trump administration's second term represents uncharted territory—the first instance where a former president returned to office after facing multiple criminal investigations. Prosecutorial independence norms have eroded measurably since 2020, and Trump has signalled intent to investigate his investigators. The 0% implied probability assumes either that such charges won't materialise or that the market creator's category definitions exclude relevant actors.

Catalysts centre on DOJ personnel decisions and Trump administration prosecutorial priorities. Watch for any appointment of special counsel or task force targeting prior Trump investigators, announcements from the Justice Department regarding investigations into DOJ conduct, and congressional hearings that might precede charges. Recent reporting indicates Trump allies have discussed potential investigations into Smith and FBI officials involved in the Mar-a-Lago search. The consensus appears to treat federal charges as politically implausible rather than legally impossible—a distinction worth testing against emerging prosecutorial signals.
