About This Event
During the 2025-2029 term If X Supreme Court Justices are confirmed during the 2025-2029 presidential term, then the market resolves to Yes.
What Prediction Markets Are Forecasting
Traders on Kalshi are weighing in on a surprisingly specific question: how many Supreme Court justices will the next president confirm during the 2025-2029 term? Right now, the leading prediction is that exactly one justice gets confirmed, and the market puts that at roughly 43%, which is close to a coin flip. The other scenarios, zero or two or more, make up the rest of the probability mass.
In plain terms, the market sees a single confirmation as the most likely outcome, but it's not a slam dunk. There's a real chance the number could be zero, which would be a notable break from recent presidential history. Every president since Jimmy Carter has confirmed at least one justice, and most have confirmed two or more.
Why the Market Sees It This Way
Several forces are pulling the odds toward exactly one. First, the current Court has two justices over 70: Clarence Thomas is 76 and Samuel Alito is 74. Retirement speculation has been constant, but neither has shown signs of stepping down, and the market is pricing in a modest chance that one of them leaves during this term.
Second, the Senate math matters. If the president's party controls the Senate, confirmations move quickly. If not, the process becomes a slog, and the White House may choose to wait rather than burn political capital on a doomed nominee. The market is essentially betting that conditions will be favorable enough for one confirmation but not so favorable that two become realistic.
Third, historical rhythm. The average presidential term sees about two confirmations, but that average is skewed by eras when the Court turned over rapidly. The current Court has been stable since 2020, and aging justices tend to retire one at a time, not in pairs.
Key Dates and Events to Watch
The big signals will come from the justices themselves. Any retirement announcement would dramatically shift the odds. The Court's term ends in late June, and retirements are typically announced in spring or early summer, so watch for news between March and July of each year.
The 2026 midterms also matter. If the president's party loses the Senate, the window for confirmation narrows considerably. The market will react to polling shifts and primary results as early as late 2025.
How Reliable Are These Predictions?
Prediction markets have a mixed but generally decent track record on political events. They're quite good at forecasting elections and legislative outcomes close to the event, but less reliable for long-horizon questions involving individual human decisions. Whether a 76-year-old justice retires is deeply personal and hard to model. No market can predict health issues or personal circumstances.
That said, the collective wisdom approach has value. The market is synthesizing retirement rumors, political calculus, and historical patterns into a single number. It's not a crystal ball, but it's a reasonable baseline. If you're curious about the future of the Court, checking these odds periodically will tell you more than most pundits will.
Current Market Outlook
Kalshi traders currently price a 43% chance that the next President confirms at least one Supreme Court justice during the 2025-2029 term. That's a market saying "maybe" with a slight lean toward yes. A 43% probability means the market views one confirmation as plausible but far from guaranteed, roughly equivalent to a coin flip weighted slightly against.
The contract structure matters here. It's a threshold question, not a count. One confirmation resolves yes. Two or three also resolve yes. So the 43% figure captures the probability of at least one vacancy opening and being filled, not the odds of a specific number of confirmations.
Key Factors Driving the Odds
The Supreme Court has nine seats, and none are currently vacant. But three justices are over 70: Clarence Thomas (76), Samuel Alito (74), and Sonia Sotomayor (70). Historical retirement patterns suggest roughly one vacancy per presidential term is normal, but the current Court has gone four years without a retirement, which is unusual.
The political composition matters enormously. If the President is a Republican, a Thomas or Alito retirement creates an immediate confirmation fight with a 53-47 Republican Senate. If a Democrat wins, Sotomayor's seat becomes the focus, and Democrats would need to hold the Senate to confirm anyone at all.
Senate dynamics are the hidden variable here. Even with a vacancy, a divided government can stall confirmations indefinitely. The 2016 Merrick Garland precedent showed that a Senate can simply refuse to hold hearings. That possibility keeps the number below 50%.
What Could Change These Odds
The 2026 midterms are the biggest swing factor. If the President's party loses the Senate, confirmation odds drop sharply regardless of who retires. Conversely, a President whose party controls both chambers faces a much smoother path.
Health events are the wild card. Justices serve life terms, and medical emergencies can force retirements on short timelines. The market's 43% seems to price in a baseline probability of natural retirement plus a smaller probability of health-driven vacancies.
The 2028 election also creates a timing constraint. A justice retiring in 2029 would fall outside the contract window, which runs through the full term. Traders should watch for any public statements from justices about retirement plans, as those historically move these markets more than any other signal.

Overview
The 2025-2029 presidential term presents a unique opportunity for the incumbent to shape the United States Supreme Court. The topic of how many Supreme Court justices the President will confirm during this period is a central question in American politics, given the Court's lifetime appointments and its role in interpreting the Constitution. As of the start of the term, the Court has nine justices, with three over the age of 70: Justice Clarence Thomas (born 1948), Justice Samuel Alito (born 1950), and Justice Sonia Sotomayor (born 1954). The possibility of retirements or vacancies during the term could lead to one or more confirmations, which would have long-lasting effects on the ideological balance of the Court. President Donald Trump, who began his second term in January 2025, has already had a significant impact on the Court. During his first term (2017-2021), he appointed three justices: Neil Gorsuch (2017), Brett Kavanaugh (2018), and Amy Coney Barrett (2020), moving the Court's ideological balance to a solid 6-3 conservative majority. This precedent sets the stage for potential additional appointments in his second term, though the number of vacancies will depend on retirements, deaths, or other unforeseen circumstances. The Senate's role in confirming justices is critical. With a Republican majority in the Senate for the 119th Congress (2025-2026), the confirmation process is likely to be smoother for the President than if the Senate were controlled by the opposition. However, the political dynamics could shift after the 2026 midterm elections, which might affect the confirmation process in the latter half of the term. Interest in this topic is high among legal scholars, political analysts, and the public because Supreme Court decisions affect nearly every aspect of American life, from abortion rights and gun control to environmental regulations and voting laws. The number of confirmations during this term will determine the Court's direction for decades, making this a subject of intense speculation and strategic planning by both political parties.
Historical Context
The number of Supreme Court justices has been fixed at nine since 1869, but the confirmation process has varied widely. In the 20th century, presidents averaged about two appointments per four-year term. For example, Franklin D. Roosevelt appointed eight justices during his 12-year presidency, while Jimmy Carter appointed none. More recently, Donald Trump appointed three in his first term, while Barack Obama appointed two in his first term and one in his second (Merrick Garland was not confirmed due to Republican inaction). The 2016 death of Justice Antonin Scalia and the subsequent refusal of the Senate to hold hearings for Merrick Garland set a precedent for highly politicized confirmations. In contrast, the 2020 confirmation of Amy Coney Barrett, just weeks before the election, demonstrated that a president can push through appointments even in a polarized environment. The current Court's ideological balance, with a 6-3 conservative majority, has been shaped by these recent appointments, and any new confirmations could solidify that majority for decades. Historical patterns suggest that retirements often occur when the president's party aligns with the justice's ideological leanings, as seen with Justice Anthony Kennedy's retirement in 2018, which allowed Trump to appoint Kavanaugh. This dynamic is likely to influence decisions by Thomas and Alito, who may choose to retire during Trump's term to ensure their successors are conservative.
Why It Matters
The number of Supreme Court confirmations during the 2025-2029 term will directly shape the Court's decisions on critical issues such as abortion, gun rights, affirmative action, and the scope of federal regulatory power. A single appointment can shift the Court's direction, as evidenced by the overturning of Roe v. Wade in 2022, which was made possible by the three Trump-appointed justices. Further conservative appointments could lead to rulings that restrict abortion access, limit LGBTQ rights, or expand gun rights, affecting millions of Americans. Beyond the immediate legal outcomes, the confirmation process itself has significant political and economic implications. A contentious confirmation battle could deepen partisan divisions and affect public trust in the judiciary. Additionally, businesses and investors closely watch the Court's composition, as rulings on issues like environmental regulations, labor laws, and corporate liability can alter the business environment. The confirmation count is therefore not just a matter of judicial procedure but a barometer of the nation's political trajectory and its impact on daily life.
Current Status
As of early 2025, the Supreme Court has no vacancies, and all nine justices are serving. President Trump has not yet announced any nominations, but speculation is high that he may have the opportunity to fill a vacancy if a conservative justice retires. Justice Thomas has been the subject of retirement rumors, but he has not indicated any plans. The Senate is controlled by Republicans, which facilitates the confirmation process. The 2026 midterm elections could alter the Senate balance, potentially making it harder for Trump to confirm a nominee in the latter half of his term. The market's resolution will depend on actual vacancies and confirmations, which are uncertain and influenced by health, political strategy, and unforeseen events.
Frequently Asked Questions
How many Supreme Court justices can a president appoint in one term?
There is no legal limit; the number depends on vacancies that occur. Historically, presidents have appointed anywhere from zero to four justices in a single term. The current term could see zero to three or more, depending on retirements and other factors.
Which Supreme Court justices might retire during 2025-2029?
The most likely candidates are the three oldest justices: Clarence Thomas (born 1948), Samuel Alito (born 1950), and Sonia Sotomayor (born 1954). Thomas and Alito might retire under a Republican president to ensure conservative successors, while Sotomayor would likely wait for a Democratic president.
What is the process for confirming a Supreme Court justice?
The President nominates a candidate, who then undergoes a Senate Judiciary Committee hearing and vote. If approved, the full Senate votes on confirmation, requiring a simple majority. The process typically takes about 70 days, but can be expedited or delayed for political reasons.
How does the Senate composition affect Supreme Court confirmations?
A simple majority is needed for confirmation. If the President's party controls the Senate, confirmations are more likely to succeed. If the Senate is controlled by the opposition, the process can be blocked, as seen with Merrick Garland in 2016.
What impact would a new Supreme Court justice have on major issues?
A new justice can shift the Court's ideological balance, affecting rulings on abortion, gun control, religious liberty, and executive power. For example, the 2022 Dobbs decision overturning Roe v. Wade was possible because of the three Trump-appointed justices.
Could the number of Supreme Court justices be changed during this term?
Changing the number requires legislation passed by Congress and signed by the President. There are proposals to expand the Court, but they face significant political hurdles and are unlikely to pass in the current Congress.
