Will Samuel Alito announce his retirement by 2026?

Platform comparison

Market context

Samuel Alito, aged 76, has made no public announcement regarding retirement and is actively hiring clerks for the next term, with sources confirming he intends to serve into at least 2027[1]. This behaviour aligns with the historical pattern where Supreme Court justices typically retire near the average age of 80, a threshold Alito has not yet reached[2]. Recent analyst consensus, including confirmations from CBS News and Fox News, strongly predicts he will not retire this year, mirroring the 0% implied probability on the primary prediction market despite a divergent 40% odds line on Polymarket for a December 31 announcement[3][4].

Traders should monitor the Supreme Court’s term schedule and any official statements from Alito’s office, as the resolution depends solely on his formal announcement rather than the effective date of retirement[5]. While the White House reportedly exerts pressure on older justices like Thomas and Alito to retire, no concrete catalyst has emerged to suggest an immediate departure[7]. The next critical window will be the end of the current term or the start of the 2027 term, where hiring patterns and public health updates may signal a shift, though current indicators suggest continued service[1].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
