Market context
The real-world event in question is whether Mohammed bin Salman, Saudi Arabia’s de facto ruler and Crown Prince, will cease holding leadership power before the end of 2026. In prediction markets, a YES share pays out if this event occurs, while a NO share pays out if he remains in power throughout the settlement window. Currently, the crowd assigns a 0% probability to YES, reflecting near-total confidence in his continued rule.
Historically, sudden removals of Saudi leaders are rare; power transitions within the House of Saud typically follow negotiated family consensus rather than abrupt dismissals. Mohammed bin Salman’s consolidation of authority—becoming Crown Prince in 2017 and Prime Minister in 2022—has entrenched him as the kingdom’s central figure, with his brothers controlling defence and energy [1][2]. Comparable cases, such as the gradual sidelining of King Salman, show that Saudi leadership shifts are usually pre-announced and institutionalised, not sudden ousters.
Traders should monitor official royal decrees, cabinet reshuffles, and King Salman’s health, as any formal announcement of resignation or removal would instantly resolve the market to YES. Recent reports confirm Mohammed bin Salman’s role as prime minister has expanded his control over ministries and bureaucracies, further reducing the likelihood of displacement [1]. With no credible signals of internal dissent or external pressure threatening his position, the market’s 0% probability aligns with the current geopolitical stability surrounding his leadership.
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
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
