Anthropic expected to list at about $1.45 trillion as lower bets fade

Traders still expect Anthropic to go public at a valuation of about $1.45 trillion, but they are no longer confident which side of $1.5 trillion it will land on. A value between $1.25 trillion and $1.5 trillion, strongly favored on Tuesday afternoon after the company filed its proposed share price, fell back early Wednesday to roughly a toss-up, giving up all of that jump in well under a day. No reported news explained the retreat.

That range remains the likeliest outcome, though only narrowly. The range above it, $1.5 trillion to $1.75 trillion, has moved the other way: it collapsed to a long shot around midday Tuesday and has since recovered to unlikely but well within reach. A value below $1.25 trillion is a long shot. Overall, traders expect $1.45 trillion, down from the $1.5 trillion they anticipated when the story began, with most bets falling between $1.3 trillion and $1.7 trillion.

Anthropic filed proposed terms on Tuesday, seeking $70 to $78 a share for 825 million shares, according to an amended filing with the Securities and Exchange Commission. Axios estimated that the top of that range would imply a fully diluted valuation of roughly $1.37 trillion and a market capitalization of about $1.02 trillion. The filing followed a $70-to-$80 draft that was circulated and then retracted.

The filing's reach showed elsewhere. Traders pulled back bets that Anthropic's valuation will reach $1.75 trillion by the end of December, which went from a toss-up to unlikely, and trimmed bets on it reaching $1.5 trillion by then, though that is still seen as likely. Bets that its market capitalization will close its first trading day between $0.9 trillion and $1.2 trillion rose from a long shot to merely unlikely.

The $1.25 trillion to $1.5 trillion range has traveled a long way in a week. It was a long shot on Nov. 4, climbed on Nov. 5 and Nov. 6 to about even, and held there through the weekend. It jumped around midday Tuesday, eased through the afternoon and evening, and dropped early Wednesday.

The earlier climb followed reports of investor resistance. Reuters reported on Nov. 5 that prospective investors were pushing for a more attractive valuation and questioning the planned roadshow timing. In October, Reuters had reported that talk of a roughly $2 trillion valuation had given way to about $1.5 trillion amid concerns about slowing revenue growth and AI financing costs.

Anthropic filed to go public on Oct. 26. Axios reported that trading was likely to begin next week, though the amended filing does not set a pricing date, and most traders expect the listing in mid November. The question turns on the fully diluted valuation at the final IPO price, which could still land outside the proposed range, and a value of exactly $1.5 trillion would count in the higher range.
