Anthropic to sell up to $3.5 billion of shares in Japan

Anthropic will sell up to 552.9 billion yen, about $3.5 billion, of new shares to investors in Japan as part of its United States public listing, according to a filing reported by Reuters on Monday.

Why it matters: A $3.5 billion Japan tranche, larger than the $2.2 billion Japanese investors took in SpaceX's record June listing, shows the largest United States technology offerings are now being sized for Japanese demand as a distinct funding channel.
