In March, 2022, Phil McParlane posted a Twitter thread looking for sponsors for his newsletter. He decided to promote it as an auction and started the bidding at $1.
The idea quickly got traction. He regularly posted updates of bids, which allowed the bidders to get more exposure.
Cameron Whitehead won the auction, with a bid of $165. Two other people offered to match his bid. Phil earned $495 from this auction.
He ran a similar auction for his 4 day week newsletter in July. This time, people had four hours to submit their bid. The newsletter went to 30k subscribers and attracted a winning bid of $800.
Check out the second auction thread. He posted a second thread summarizing the auction.
