Make sure you do not measure this by how the "total solved" changes, since this will include old solutions also. You have to manually count which of those solutions happened during 2026.

@ThomaslZZ0 The market will be resolved by the difference between the N in “N have been solved” as stated on the website at the end of the year and 451. Right now, the website says “466 (41%) have been solved” so the difference today is 15.

@BraydonDymm You should reword "solved by the end of 2026" as "solved during 2026". And you may want to specify a timezone.

@vee updated

On 1 January 2025 there were 292 solved out of 895 total

@duck_master I’m using the website as the official source. Do you have a different official source?
