Anthropic is reportedly laying the groundwork for an IPO — possibly as early as 2026 — in a move aimed at beating OpenAI to the public markets. According to the report, Anthropic has tapped Wilson Sonsini (the law firm behind Google’s and LinkedIn’s listings) and hired CFO Krishna Rao, who helped take Airbnb public. The company is also assembling an internal checklist of changes needed to list and is pursuing private capital at a valuation north of $300B; Microsoft and NVIDIA are said to be potential investors for up to $15B combined.
OpenAI is also preparing for a public listing and has been discussed at valuations as high as $1 trillion. The newsletter highlights why timing matters: the first of these AI giants to list may set pricing expectations for the sector, and public markets will scrutinize growth and revenue to decide if current private valuations are sustainable.
The same briefing also covers related Anthropic developments: a leaked “Soul” document published after extraction from Claude 4.5 Opus (Anthropic confirms its authenticity) describing Claude’s safety priorities and a company survey showing heavy internal use of Claude (roughly 60% of tasks) alongside worker concerns about job impact.
