How are prediction markets taxed in Luxembourg?

Luxembourg has two main treatments: (1) Gambling — tax-free for casual bettors, (2) Speculative gains — if held less than 6 months, half of the gain is included in taxable income at progressive rates (up to 42%).

What is the 6-month holding rule?

Gains on assets held for less than 6 months are considered speculative (bénéfice de spéculation). Only half of the gain is included in taxable income. Assets held longer than 6 months are generally tax-free.

Are gambling winnings tax-free?

Generally yes. Casual gambling/betting winnings are not taxable in Luxembourg. If prediction market trading is considered recreational betting, no tax applies.
