Shaires Holdings Ltd (AIM:SHR) has completed its acquisition of indirect interests in Anthropic and Stripe, giving the AIM-listed investment company exposure to two of the world's most valuable private technology businesses.
The London-listed vehicle invested a total of $25.4 million through a special purpose vehicle, with $16.2 million allocated to Anthropic and $9.2 million to Stripe.
The Anthropic stake was acquired at the artificial intelligence company's $965 billion Series H valuation, equivalent to around $589.01 per share.
That gives Shaires an indirect interest of approximately 0.001% in Anthropic's equity.
The Stripe exposure was bought at the payments group's $159 billion February 2026 tender valuation, equivalent to about $63 per share.
Shaires' indirect stake in Stripe amounts to roughly 0.006% of the company.
Anthropic, the developer of the Claude family of AI models, reported an annualised revenue run rate of approximately $65 billion as of July 2026 on a management basis.
Stripe processed around $1.9 trillion of total payment volume in 2025 and acquired the AI model routing platform OpenRouter in August 2026.
Both companies are privately held and do not publish audited financial statements.
Shaires said the closing follows satisfaction of the customary conditions set out in its announcement of 13 August 2026.
The company's proposed investment in Figure AI, also announced that day, has not yet completed, with a further update expected in due course.
Chief executive Vivek Seth said Anthropic and Stripe represented the calibre of businesses Shaires wanted at its core, citing their scale and long-term growth potential.
Seth added that Stripe was increasingly becoming part of the economic infrastructure underpinning the AI economy, while Anthropic continued to operate at the frontier of artificial intelligence.
