How many Supreme Court justices will the President confirm?

The core question is not whether the President wants to confirm a justice, but whether a vacancy appears and the Senate can confirm a nominee before the term ends in January 2029. With roughly 2.5 years left, the Court’s older bloc creates a real vacancy risk, but the short remaining window also means timing matters a lot; a vacancy in late 2028 is very different from one in 2026. That makes exactly one confirmation a plausible outcome, but not one that should be treated as overwhelmingly likely.

My independent read is that one confirmation is slightly more likely than zero, but not by enough to justify a very high price. The same age and tenure profile that supports a single opening also leaves meaningful tail risk for two openings, especially if a retirement is strategically timed or if there is an unexpected death or health event. In addition, Senate control and election timing can turn a would-be vacancy into a delayed or blocked confirmation, which trims the exact-one scenario more than the headline vacancy probability suggests.

Compared with the market, I am a touch less bullish on exactly one and a bit more open to the tails. The market’s 40% on one looks slightly rich relative to the combined weight on zero and two, because the path to a second confirmation is not remote and the path to no confirmations is still very live given the limited time remaining. This is not a dramatic mispricing, but the market appears to understate how often the outcome could land on zero or two rather than exactly one.
