๐ Enhanced Key Takeaways
- โขSpaceX's valuation reached $800 billion in December 2025 through an insider share sale and is reportedly preparing for a potential 2026 IPO targeting approximately $1.5 trillion, aiming to raise over $30 billion.
- โขMichael Burry's skepticism regarding SpaceX's valuation is partly based on its S-1 filing, which reportedly disclosed $18.7 billion in revenue but a net loss of $4.9 billion in the previous year, leading him to question its projected $1 trillion or $2 trillion public valuation.
- โขBurry criticized Anthropic's $965 billion valuation, asserting that its AI model development is 'far too expensive' and that computing power will eventually be commoditized, creating a 'false demand signal' for current infrastructure buildouts.
- โขAnthropic recently secured $65 billion in a Series H funding round in May 2026, which propelled its post-money valuation to $965 billion, surpassing OpenAI's most recent valuation of $730 billion.
- โขSpaceX has invested over $15 billion in the development of its Starship rocket, a substantial expenditure that underpins a significant portion of its targeted IPO valuation, with the ambitious goal of achieving 'airline-like' reliability and drastically reduced launch costs.
๐ ๏ธ Technical Deep Dive
- SpaceX Starship: The Starship program has incurred over $15 billion in development costs, significantly more than the Falcon 9's $400 million development. The goal is to achieve 'airline-like' reliability and a projected launch cost of approximately $300 per kilogram to orbit for an expendable V3 vehicle, which would drastically undercut existing heavy-lift options. The Starship system is a two-stage, fully reusable super heavy-lift launch vehicle, intended to succeed Falcon 9 and Falcon Heavy. As of May 27, 2026, Starship has launched 12 times, with 7 successful flights.
- Anthropic Claude (Constitutional AI): Anthropic's Claude models are developed with a strong focus on AI safety, reliability, and alignment, utilizing a training method called Constitutional AI. This approach guides the model using a written set of principles, or a 'constitution,' rather than relying purely on human feedback. Anthropic published an updated, comprehensive constitution for Claude in January 2026, shifting from rule-based to reason-based AI alignment, which explains the logic behind ethical principles. This framework establishes a four-tier priority hierarchy: safety, ethics, compliance, and helpfulness. The constitution is written primarily for Claude itself, to give it the knowledge and understanding needed to act ethically.
