Who Wins and Why
| Outcome | Market | Model | Why |
|---|---|---|---|
| Clarence Thomas | 50.0% | 27.0% | No resignation has occurred as of March 26, 2026, and Justice Thomas has hired clerks through October Term 2027, strongly indicating he does not plan to resign during a potential Trump term, despite market speculation based on age and political timing. |
| Samuel Alito | 70.0% | 49.1% | The evidence indicates Justice Alito has no plans to resign, reinforced by his hiring of clerks for the October Term 2025 and expectations to fill future terms, directly contradicting the market's high probability driven by mere speculation about his age and book release. |
| Sonia Sotomayor | 10.0% | 2.6% | Web research and background checks confirm that Justice Sotomayor has not resigned and has no plans to, overwhelmingly indicating a lower probability for this event, while the market's positive probability accounts for the inherent possibility of unexpected resignations. |
| John Roberts | 14.0% | 2.8% | John Roberts explicitly stated in May 2025 he has no plans to retire and will go "feet first," strongly indicating a lower probability of resignation, though the market's remaining probability could account for unforeseen health or personal circumstances. |
