What

Why it matters

Open questions

• How will Anthropic's S-1 address the direct contradiction between SpaceX's $45B compute disclosure [13][14] and Musk's personal denial [12], and how will SEC reviewers handle two simultaneous registrations with conflicting characterizations of the same contract?

• Will the SEC require Anthropic to standardize its run-rate methodology — 28-day consumption × 13 plus monthly subscriptions × 12 [10] — and how does the $45B/$47B discrepancy between the S-1 announcement [8] and Series H materials [6] resolve?

• Was Oceanus pulled because of the leak [25], a product decision, or an IPO-related disclosure concern, and does its ~3x Opus pricing [24] still represent a planned revenue tier in the offering narrative?

• Does OpenAI's parallel filing at ~$852B [16][19] affect the valuation case Anthropic makes to public market investors, and do two overlapping AI IPO roadshows — already drawing dotcom bubble comparisons [18] — compress or widen each company's room to price?

Perspectives

Tensions

• Musk personally stated SpaceX holds no long-term Colossus lease with Anthropic [12], but SpaceX's own S-1 filing discloses Anthropic pays SpaceX $1.25B/month in a $45B total arrangement [13][14], contradicting Musk's denial in his own company's SEC filing. [12][13][14][32]
• Anthropic's run-rate methodology — 28-day consumption × 13 plus monthly subscriptions × 12 [10] — is non-standard, and the $45B/$47B discrepancy between the S-1 announcement [8] and Series H materials [6] is unresolved disclosure the SEC will formally evaluate. [10][6][8]
• Anthropic ($965B post-money) and OpenAI (~$852B post-money) are simultaneously in confidential SEC registration [8][16], forcing parallel public disclosure of overlapping competitive intelligence that neither company controls independently, while financial press draws dotcom-era comparisons [18]. [8][16][18][19]
• MCP as foundational enterprise infrastructure vs. a CVE-tracked vulnerability surface: 43 AAIF members [28], but registered CVEs for Claude Code [26] and OWASP's Tool Poisoning catalogue [27] challenge the enterprise-ready narrative at peak institutional momentum. [26][27][35][28]
• Revenue trajectory vs. billing reform cap: Bessemer projects $100B annual run rate [21], but the $500M accidental-spend incident [22] and subsequent usage-based billing shift [23] raise whether the fastest revenue growth was partially driven by governance gaps now being corrected. [21][22][23]
