April 3 (Reuters) – Elon Musk is requiring banks and other advisers working on SpaceX’s ‌planned IPO to buy subscriptions to ‌Grok, his artificial intelligence chatbot, the New York Times ​reported on Friday, citing people familiar with the matter.

Some banks have agreed to spend tens of millions of dollars a year on the ‌chatbot and have ⁠begun integrating it into their IT systems, the report said.

Morgan Stanley, Goldman ⁠Sachs, JPMorgan Chase, Bank of America and Citigroup are serving as active bookrunners, or the ​lead banks ​managing the deal, Reuters ​reported earlier this ‌week.

Musk and SpaceX did not respond to Reuters’ requests for comment. The five banks did not immediately respond to Reuters’ queries.

The Starbase, Texas-headquartered rocket maker boosted its target initial public offering ‌valuation above $2 trillion, according ​to a Bloomberg News report ​a day ​earlier, setting the stage for what ‌could become the largest stock ​market listing ​on record.

The company aims to raise a record $75 billion, which would dwarf previous mega-IPOs ​such as ‌Saudi Aramco in 2019 and Alibaba in ​2014.
