Market context
Russia has not conducted an actual nuclear detonation, and the contract’s 0% crowd-implied probability reflects how far that remains from the current baseline. Recent Russian activity has centred on nuclear-capable missile launches and exercises rather than weapons tests, including a successful Sarmat launch in May and a separate unannounced nuclear drill, both of which are signalling events rather than qualifying detonations. [2][4][12]
That keeps this market closer to historical “watch but don’t price” territory than to a live escalation set-up. Comparable cases show traders usually stay near zero unless there is an explicit political break with the nuclear test moratorium, clear site preparation at Novaya Zemlya, or a formal Russian announcement that removes ambiguity; absent that, even dramatic rhetoric has tended to move attention more than settlement odds. Prediction-market commentary in August put Russian nuclear-test probabilities for 2026 at near-zero to low double digits, while analyst consensus has framed the recent exercises as serious but still unlikely to be a pretext for an actual detonation. [1][3][6][11]
The main catalysts are official statements from Putin, the defence ministry, or state media about “full-scale” tests, any visible preparation at established test infrastructure, and reciprocal pressure tied to wider US-Russia nuclear signalling. The most recent news flow still points the other way: Russia’s nuclear activity in May was exercise- and missile-test-driven, not a treaty-breaking detonation, and the latest commentary says no credible report has emerged of an actual nuclear test during the current window. [1][2][8][15]
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
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
