Musk had briefly supported OpenAI's ICO plan before changing his mind and ceasing his support.

CoinFeed reported on April 30th that OpenAI disclosed in previous filings that in mid-January 2018, Elon Musk congratulated them on their successful fundraising, agreed to their Initial Coin Offering (ICO) to raise $10 billion—which would involve a for-profit subsidiary—and told them they had resolved their long-term funding issues. However, by the end of January, he told them he was no longer supporting ICOs (at which point they had also lost faith in ICOs) and believed OpenAI was "doomed to fail relative to Google." Then, in February 2018, Elon Musk concluded that OpenAI would not be able to raise sufficient funds. That same month, he resigned, focusing instead on developing Artificial General Intelligence (AGI) at Tesla.
