Anthropic expects to match or beat the size of SpaceX’s record-setting initial public offering, according to people familiar with the matter, in the latest sign of overwhelming demand from investors looking to profit from the artificial intelligence boom.

The Claude developer is running the numbers as it prepares to file publicly for its potential mega-IPO as soon as the end of this month, the people said. Recent investor briefings led by Chief Financial Officer Krishna Rao skirted the question of valuation, they said.

Elon Musk’s rocket and satellite firm raised $75 billion at the outset, making it the biggest first-time share sale ever, data compiled by Bloomberg show. The final figure increased to $86.2 billion with the so-called overallotment option, which is typically exercised if shares rise in early trading.
