Clarence Thomas, the Supreme Court’s longest-serving justice at age 78, has shown no public or private signals of retirement plans as of late August 2026. Sources close to him confirmed in April that he does not intend to step down this year or in the immediate term, aligning with his past statements favoring service into the 2030s and his approach toward the longest-tenure record in 2028. He remains active, including recent interviews and oral arguments, with no reported health concerns, ethical issues, or institutional pressures. President Trump has expressed a preference for Thomas and Justice Alito to continue serving rather than create vacancies ahead of Senate dynamics. Any announcement would typically occur at term’s end, but low market-implied probabilities for 2026 dates reflect the absence of catalysts that have historically prompted exits.
