Am I missing something here? The LMarena data hasn’t been updated for over a week, so we’re missing a whole week of data for the month of may aren’t we?

@Cole1 no, the lmarena updates every week or so, this is normal stuff. it will probably update on monday or tuesday

but if you think that was a crux for whether claude opus 4 ends up #1, there's this market yuo might wanna bet on:
