Market context
Polymarket prices Putin leaving the Russian presidency by 30 June 2027 at about **8% YES**, so the on-chain market is still assigning a strong **No** base case on the USDC-settled, Polygon-based conditional tokens contract. That price implies traders see a low-probability event, but not a vanishing one, with the market paying for a narrow tail risk rather than a mainstream transition.
The comparison point is Russia’s recent political structure: Putin was re-elected in 2024 for a further six-year term, and the constitution after the 2020 amendments allows him to remain eligible for more terms, which is why the 2027 window sits inside an already secured mandate.[13][14] That is consistent with wider forecast markets that have tended to put his exit well beyond this date, including Metaculus, which currently centres on 2030 rather than 2027.[11] In practice, the 8% price is less about routine electoral turnover and more about an extraordinary interruption to continuity, such as resignation, formal removal, or incapacity.
For traders, the main catalysts are Kremlin succession signalling, any official resignation or dismissal announcement, and major health or detention rumours that become credible enough to move the market, because the contract resolves to Yes on announcement alone if departure is declared before expiry. Recent reporting on Polymarket has shown the June 2027 rung can reprice quickly after shocks tied to the war in Ukraine, even when nothing has changed institutionally, which is a reminder that this market reacts to headlines as much as to hard political mechanics.[6][15] The relevant dependency is simple: until there is visible evidence of elite rupture or a formal Kremlin statement, the contract remains anchored to continuity.
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.
