Will Bosi repeated Burden of Dreams in April 2023. I think he's heading to the USA soon (already?) and I've heard speculation that he might try hard boulders there. (Megatron? Return of the Sleepwalker?) (Wait, isn't it too hot at this time of year?)

This market resolves YES if Will Bosi climbs any existing boulder graded at 9A (V17), or if he makes a first ascent and proposes the grade 9A. If he climbs an existing 9A and downgrades it, this market still resolves YES.

(If a new "9A" is put up after market creation, and then Bosi repeats it and downgrades it to something ridiculously low such that nobody could reasonably have expected it to be 9A then I reserve the right to resolve NO. But if it's Megatron, Return of the Sleepwalker, or a new problem that could reasonably be considered 9A then the market resolves YES. This is a little bit of discretion on my part, but it's an unlikely edge case of an unlikely edge case so I don't think it'll be an issue. If a new 9A boulder is put up after market creation and you think Bosi might repeat it, feel free to ask me in the comments if it counts.)
