Ai16z co-founder Shaw said in a post on X that code he previously published in the GitHub repository lalalune/pumpfun-source was not open source. He said the code did not belong to him and that he had never had the authority to publish, license or authorize its use.
Shaw said license notices in the repository, including “Copyright (c) 2026 Shaw,” were invalid and granted no rights. He warned people not to treat those notices or his earlier statements as permission to use, copy, fork, modify, build on or distribute the code. He also said the pump.fun code is copyright-protected and should not be distributed or reverse-engineered.
Foresight News reported that Bracket Company Inc., pump.fun’s parent company, had sent Shaw a cease-and-desist letter through law firm Brown Rudnick on October 29. At the time of its report, the original repository had either been deleted or made private; the report did not establish which.
