Manifold just launched a USDC prize drawing where you can pay mana for tickets (you also get a first free ticket): https://manifold.markets/prize

In the FAQ they say "We intend to keep running Prize Drawings and will share as much information as we can about our plans for future drawings". This market resolves YES if a second real-world money prize drawing with tickets purchasable in mana starts before the end of 2026 (even if it does not complete), and resolves NO at the end of 2026 otherwise. Charity lotteries do not count for this; there must be a real-world monetary prize claimable by users for themselves.
