Market context

Parliamentary elections in Sweden are set for 13 September 2026, when the Riksdag will elect the next Prime Minister, a process that currently shows a 0% market price for any specific individual on Polymarket. On-chain, this contract trades in USDC on Polygon using conditional tokens, meaning liquidity is thin and prices reflect the uncertainty of coalition formation rather than a settled candidate. The zero probability is not an error but a mechanical signal that no single name has yet secured the parliamentary majority required to assume office officially.

Historically, Swedish Prime Ministers emerge from complex multi-party negotiations, as seen in 2018 when Stefan Löfven’s Social Democrats needed support from the Greens and Centre Party after a fragmented election. Similar to that period, current polls show Socialdemokraterna leading with 32.4%, followed by Sverigedemokraterna at 19.4% and Moderaterna at 17.2%, creating a scenario where no party can govern alone[2]. This fragmentation explains the market’s caution: past elections required months of post-vote bargaining, and the 0% price mirrors the absence of a definitive winner before the September vote.

Traders should monitor coalition announcements, polling shifts, and the Swedish government’s election security measures against foreign malign influence, which could delay or alter outcomes[5]. The key catalyst is the September 13 election itself, when the 349 Riksdag members are elected and begin Prime Minister negotiations[1]. Until formal appointments occur, conditional token prices will remain volatile, with USDC liquidity likely to surge only after a clear coalition emerges. Watch PolitPro’s latest trend updates for coalition scenarios, as these often precede official government declarations[2].

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
