Anthropic (ANT) IPO to sell 825mln shares, according to a draft prospectus cited by Reuters; indicative band of USD 70/shr to USD 78/shr

• Cornerstone investors include: AMD (AMD), Broadcom (AVGO), Alphabet (GOOG), Micron (MU), Microsoft (MSFT), Nvidia (NVDA) & TSMC (TSM).
• Cornerstone investors to purchase USD 26bln of common stock, in a private placement.
• IPO to raise as much as USD 64.4bln.

A raise of this size has no precedent in US listing history, and the structure is as notable as the scale: the cornerstone book is drawn almost entirely from the company's own supply chain and distribution partners, the chip designers, foundry and hyperscalers whose hardware and cloud capacity the issuer consumes. That pattern of suppliers and customers taking equity stakes has been a recurring feature of the AI complex, and past episodes of such cross-holding have been read two ways, as validation of demand and as circular financing that flatters the revenue of the participants. The listed tags are therefore the transmission channel: the trade runs through the peer set's perceived revenue visibility as much as through the debut itself. On mechanics, heavy cornerstone and private placement commitments shrink the effective free float, which in prior mega-listings has meant thin early price discovery, pronounced first-day moves, and index-inclusion flows that matter more than usual. The draft-prospectus caveat matters: band, share count and cornerstone terms all remain subject to revision, and on past form the tells are whether the band is revised upward, whether cornerstone allocations hold at the cited level, and the length of lock-ups. The follow-ons are the confirmed filing, the pricing versus the band, and the syndicate's greenshoe and allocation disclosures.
