According to CoinMeta, Anthropic obtained up to $77 billion in undrawn note financing from Broadcom, Google, and Amazon. Among them, Broadcom received the largest amount of financing, reaching $42 billion, followed by Google's $20 billion and Amazon's $15 billion, which has not yet been drawn down. Google also holds an option to purchase up to $1 billion in non-voting Class N shares at the issue price during its initial public offering (IPO), which will reduce its financing amount by the same amount. Amazon's note conversion ratio cannot exceed 12% of the company, while Google's issuance limit is 14.99%, unless both parties waive this restriction.
