This market resolves YES if Duolingo launches a public Toki Pona course on its app or website before 2028-01-01 00:00 UTC. A public beta or public preview counts if ordinary users can access the course without a private invite. A waitlist, incubator placeholder, job listing, blog post, social-media announcement, forum discussion, or third-party/non-Duolingo Toki Pona course does not count unless the Duolingo course itself becomes publicly accessible. A course under a translated or alternate title counts if Duolingo clearly presents it as Toki Pona. Resolution sources: Duolingo course directory/app, official Duolingo blog/social posts, and reliable coverage that points to an actual public course. Toki Pona is a constructed language; this market was created for soweliSon's conlang market bounty. Pre-creation duplicate search found no obvious Manifold market for Duolingo launching a Toki Pona course.
