The first ever player to have hit $1Bil to my knowledge was Cleocyde back before May 2019 in the middle of Season 1.
The All Time record to my knowledge was Wqlk on the very last day of Season 1, as he was a well-respected player with the biggest public farm on the server at the time of +1,000 Cow Spawners before re-locating it to iOutcasts public farm before SUPPOSEDLY it got lost. Everyone online at the server paid Wqlk all their balance, and by the end Wqlk acquired around $3.57Bil from mostly other people's contribution.
The IRL Dealer Record possibly belongs to cowFricker / DEREKEKLOUDE with a total of ~$2.1Bil, back in Season 2 or it either belongs to Hellcat_The_One or V_PTR in Season 3/4, but cannot confirm that statement myself.
The Non-IRL Dealer (Grinding) Record belongs currently to Nathan_97 with a supposed total of $2Bil from things like Cows and Blazes, and possibly IGS included, back in the near-end of Season 3 before doing an IRL Deal with Subsy for rankups.
As Kayloo and PEEKLOBSTER says, the record is potentially $8-10Bil, but at the moment, the #1 Balance Record with verifiable evidence belongs to Wqlk back on June 21st 2019. (Potentially making it the oldest record on InvadedLands)
