Amazon announced an additional $5 billion investment in Anthropic immediately, plus up to $20 billion more in the future (tied to commercial milestones). This brings its total committed capital to as much as $33 billion. The announcement does not specify how much new equity/percentage this adds or the exact structure, but it will increase Amazon’s stake further as part of a deepened cloud/AI hardware partnership (Anthropic committed to over $100B spend on AWS over 10 years).
There is still a race to build AI Data Centers. There are announced deals but then there are delays and cancellations. Funding can be reduced or fall through.
Amazon’s Stake (as of April 21, 2026)
Prior investment: $8 billion (through 2024).
New deal (announced April 20)
$5 billion immediately + up to $20 billion more tied to commercial milestones → total committed up to $33 billion.
Valuation for the new $5 billion: $350 billion pre-money (not including the new funding), per Anthropic. (This is slightly below the $380 billion post-money valuation from Anthropic’s February 2026 Series G round.)
Analysts and prior SEC-based calculations put Amazon in the ~15–19% range before this deal (some earlier 2025 filings implied 7.8% at lower valuations, but later rounds and fair-value marks pushed estimates higher). The new $5 billion at $350–380 billion valuation adds roughly 1.3–1.4% of new equity.
Post Amazon deal estimate is Amazon will have 16–20% of Anthropic.
Google (Alphabet) still has about ~14%. This is based on court filings from the Google antitrust case and has been consistent for over a year. Google’s total investment is roughly $3 billion.
Nvidia and Microsoft have combined smaller stakes (estimated ~3–5% total together after their recent investments).
The 7 founders have about 12-15%.

Anthropic got something right that others cant, didnt figure out yet. First they had the best coding model, but not general AI. Then they get on pair even with general Ai. After that domination begins,… 4.7 is just a fraction better than 4.6, but they out a worse version out, because the flagship AI got so good and I believe them.
Maybe I’m either reading too much into things or not totally misinterpreting, but I see this as how the A.I. “bubble” thing goes. I don’t think there will be a burst. Rather, I can see how the largest tech companies will divvy up the most efficient and interesting LLM companies, and that those LLMs will begin silently conforming to the standards of their largest shareholders: big tech.
Taking it a bit further:
“Abundance for all” doesn’t require us to exchange autonomy and privacy for convenience. That would not be true abundance. We need A.I. that is personal and decentralized, umplugged, open-source, and accessible to everyone (though I realize the “unplugged” bit will be a long way off).
