Amazon to invest $25B in Anthropic, securing cloud deal through 2036

Amazon plans a $25 billion investment in Anthropic, locking in Anthropic as a cloud customer through 2036. The deal is expected to affect Anthropic’s odds in the Third Best AI Model by April 2026 market, where traders are now reassessing the company’s competitive position against OpenAI and Google DeepMind.

Market reaction

The investment is likely to move both the Third Best AI Model by April 2026 and Third Best AI Model End of April markets. The April 30 markets have just 10 days left, making them especially sensitive to new information. This capital injection could drive a 15% shift in odds across these markets. Current face value volume is at $0, but the news may draw fresh liquidity as traders reprice Anthropic’s chances.

Why it matters

Amazon’s commitment gives Anthropic both money and cloud infrastructure access, which matters directly for training and evaluating large AI models. Anthropic is competing for a top spot in public benchmarks, and $25 billion in backing through 2036 changes the resource equation against better-funded competitors.

What to watch

For traders, buying YES in the April 2026 market at current odds could pay off if Anthropic’s Claude Mythos 5 performs well on benchmarks. Watch for statements from Dario Amodei or any Anthropic performance updates before month’s end, as these would directly affect market expectations.
