I am "willo2", the top holder of YES on "MicroStrategy sells Bitcoin by May 31st".
Here's what happened:
Polymarket had a market for whether Michael Saylor's Strategy would sell Bitcoin this year, and broke that down by certain dates.
May 31st 2026
June 30th 2026
December 31st 2026
There were also two markets in 2025 that had resolved NO due to no sales occuring.
