Who will be the next Supreme Court justice?
Andrew Oldham is a credible future Supreme Court candidate, but the current evidence does not support him as the most likely next justice. I put his independent probability at 14%, with James Ho and D. John Sauer looking somewhat stronger on the present shortlist dynamics.
Analysis
Andrew Oldham is a serious conservative legal figure and clearly part of the Supreme Court feeder ecosystem, which gives him real optionality if a Republican administration gets a vacancy to fill. He is young enough to matter, has a strong appellate record, and fits the profile of a jurist acceptable to the activist and judicial-selection wings of the GOP. That said, the supplied context shows no nomination process, no vacancy-specific signaling, and no evidence that he is the active front-runner rather than one name among several plausible contenders.
Compared with the other leading names, James Ho and D. John Sauer appear at least as compelling, and arguably more so, for a near-term appointment. Ho has long been one of the most prominent conservative appellate judges in the country and is widely perceived as ideologically reliable and intellectually forceful. Sauer, as a high-profile Trump-world legal figure, may have a different kind of advantage if the White House prioritizes loyalty and confirmation strategy. Neomi Rao is a credible institutionalist choice, while Amul Thapar has prestige and judicial experience but is somewhat more constrained by age relative to a long-horizon appointment.
The market seems to be giving Oldham a respectable but not dominant chance, which is broadly sensible, but I think it may still be slightly overconfident on him relative to Ho and Sauer. Oldham’s profile is strong enough that he belongs near the top tier, yet the evidence provided does not show any unique pathway that would make him the clear favorite. In a field this open, the better interpretation is that Oldham is a live contender, not the default next justice, and the market’s 20% for him looks a bit rich versus a more balanced distribution across several conservative alternatives.
Arguments
For
- Arguments for Yes: Oldham is young, ideologically aligned, and already embedded in the appellate-to-Supreme Court pipeline.
- Arguments for Yes: His current Fifth Circuit role and feeder-network status make him a realistic candidate if the vacancy arises under favorable political conditions.
Against
- Arguments against Yes: The supplied evidence shows no nomination, no vacancy, and no White House or Senate movement for Oldham specifically.
- Arguments against Yes: Several rivals appear at least as plausible for the next opening, so Oldham is not clearly the leading contender.
Key drivers
- Oldham has a strong conservative-judicial profile and fits the Supreme Court feeder-network pattern.
- There is no current vacancy or nomination-specific evidence pointing uniquely to Oldham.
- Near-term selection may favor candidates with stronger national visibility or clearer political relationships, such as Ho or Sauer.
Risk factors
- A sudden vacancy during a Republican administration could sharply favor any well-positioned conservative judge and compress current distinctions.
- If Trump-style selection logic dominates, a loyalty or vetting advantage could elevate Sauer or another insider over Oldham.
Scenarios
Best case
A Supreme Court vacancy opens during a Republican administration, Oldham becomes an early short-lister favorite, and his combination of youth, ideology, and appellate pedigree wins the nomination.
Most likely
Oldham remains a prominent and credible future Supreme Court prospect, but another conservative contender, or an entirely different nominee, is chosen first.
Worst case
No vacancy emerges before January 2029, or a vacancy is filled by someone else who has stronger political backing, making Oldham irrelevant to the next-justice selection.

Who will Trump pardon?
AI2%MKT51%Edge-49HypedI put the chance of Barron Trump receiving a presidential pardon before Jan. 21, 2029 at 2%. There is no visible legal predicate for a pardon, and absent a federal case or at least a credible public controversy, the event is extremely unlikely.
