Contest rules
Last updated: 24 September 2026
1. Organiser
The contests are run by the founders of BestInvestor. BestInvestor is not a registered company.
2. Two monthly contests
- Prediction Champion: the highest total score from predictions settled during the month.
- Portfolio Champion: the highest simulated portfolio value at the end of the month, from a starting capital of SEK 100,000.
3. Free to enter
Entry is free. No purchase or stake is required, and you cannot pay to improve your chances.
4. Who can take part
Anyone with a BestInvestor account (16 or older) can take part. Prizes are only paid to members aged 18 or older. If a winner is under 18, the prize passes to the next eligible member in that contest’s ranking.
5. Prize
SEK 1,000 to rank 1 in each contest, each month. Other places receive no prize.
6. How winners are decided
Winners are the members ranked 1 when the month ends. At least one settled prediction is needed to qualify for Prediction Champion. If two members have the same prediction score, the one with the higher Rating ranks higher. The Portfolio Champion ranking has no automatic tie-break; if two portfolios finish on exactly the same value, we will explain how the tie is settled before paying the prize.
7. Monthly reset
Simulated portfolios reset on the 1st of each month. The month’s results are kept in the history.
8. Paying prizes
We contact winners by email within 14 days of the month ending to confirm their age and arrange payment. Winners are responsible for any tax due on their prize.
9. Withholding a prize
We may withhold a prize or disqualify a member who breaks these rules or the terms of use. This includes using multiple accounts or manipulating the contest. Questions: joakim@bestinvestor.se.
10. Law
Swedish law applies.
