This market is based on whether Leyline of Resonance, a red enchantment from Duskmourn, will be banned in any official constructed Magic: the Gathering format by January 1st, 2025. These formats include, but are not limited to, Standard, Pioneer, Modern, Legacy, Vintage and Commander.
Leyline of Resonance must be legal, in the aggregate, in a format and then prohibited for this condition to trigger. For example, if Wizards of the Coast officially announces Pre-Modern as an official format, Leyline of Resonance is not considered banned in Pre-Modern as it does not meet the underlying restrictions for legality.
Other conditions will be clarified as necessary.

3.00It is indeed banned in Arena Bo1! https://magic.wizards.com/en/news/announcements/mtg-arena-banned-and-restricted-announcement-october-22-2024
@ScottWolchok I think it's both clearly playable and also unlikely to be banned in anything anytime soon
