I have computed a snapshot estimating the July 4th content reward payouts for all top-level posts.
This is just the Steem Dollar (SMD) portion of the content rewards for top-level posts only. An equivalent value would also be distributed for the content rewards as Steem Power (SP).
This snapshot assumes that all posts/comments/votes and all accumulation of STEEM in the reward fund stopped as of block 1997811 (2016-06-02T22:09:09 UTC) until the July 4th payout. It also assumes the median price feed at time of payout on July 4th is 0.477 USD/STEEM.
