Sweden's potential accession to NATO has been a subject of considerable debate and negotiation. In recent years, the process of Sweden joining the North Atlantic Treaty Organization has seen various hurdles and developments. On 5 July 2022, an accession treaty was signed in Brussels, Belgium. However, the entry into force of this treaty is conditional on its ratification by all current NATO members. As of now, most member states have ratified Sweden's NATO membership, but a few, notably Turkey and Hungary, have expressed reservations.
The resolution of this prediction market will be based on whether or not Sweden officially becomes a NATO member before the end of the year (EOY) 2023 (UTC). The outcome will be considered "Yes" if Sweden's accession to NATO is formally completed and they become a member state of the alliance before the specified deadline. Conversely, the outcome will be "No" if Sweden does not become a NATO member by the end of 2023. Formal completion refers to the completion of all necessary ratifications and procedures required by NATO for a country to officially join the alliance. Official announcements from NATO or the Swedish government will be used to determine the resolution.
