After this weekend, No Way Home's 3-day was $20.8M, which puts it at $698.7M Domestic, which is less than $2M behind Blck Panther for 4th All-Time at the domestic box office. It will pass Black Panther tomorrow with the 4-day looking to be around $26M or so, which will put NWH somewhere around $704M.
4th is probably the highest it will climb on the all-time domestic chart with the next film being Avatar at $760M. I just don't think there's enough gas left to scrounge up an extra $56M or so, however with a very weak release schedule, it's not 100% out of the question either. I see it finishing around $730-$740M since it's starting to slow down and I just don't see it legging it out that far, but it's within the realm of possibility still.
