> Anthropic, Macquarie, and Singapore’s GIC launched Theseus Infrastructure — a dedicated data-center platform with Anthropic as anchor tenant, U.S. focus first, financiers funding most project equity. Anthropic’s existing February pledge covers consumer electricity impacts from partner-developed data centers; the venture announcement does not specify a new contractual guarantee.

**Theseus** brings sovereign and infrastructure capital to Anthropic’s planned data-center expansion. A separate, earlier Anthropic pledge addresses consumer electricity costs from partner-developed facilities.

**Anthropic**, **Macquarie Asset Management**, and **GIC** (Singapore’s sovereign wealth fund) announced a strategic partnership to create **Theseus Infrastructure** — a platform to **develop, operate, and lease** data-center facilities to Anthropic under long-term agreements. **Initial focus is the United States**, with additional sites to be identified over time. Funds managed by **Macquarie** together with **GIC** will **own the platform** and fund the **majority of equity** for each project; Anthropic is the **anchor tenant** and has an existing February commitment to cover **consumer electricity price increases** from data centers developed with partners for its workloads.

## What was announced

| Item | Detail (joint Business Wire announcement; February Anthropic pledge) |
|------|------------------------------------------------|
| **Vehicle** | **Theseus Infrastructure** |
| **Parties** | Anthropic (anchor tenant) · Macquarie Asset Management · **GIC** |
| **Scope** | Develop, operate, lease dedicated AI data-center capacity to Anthropic |
| **Geography** | **Initial focus: United States**; expand site pipeline as projects develop |
| **Equity** | Macquarie-managed funds + GIC fund **majority of equity** per project |
| **Prior company pledge** | Anthropic’s February pledge covers consumer price impacts from partner-developed facilities |

Theseus is a **build-to-suit / long-term lease** structure — not a one-off colo booking. The structure combines a named sovereign investor, a dedicated vehicle, and an anchor-tenant lab. Anthropic’s power-price pledge predates the venture.

## Limits

- First site / MW numbers not in the launch announcements.
- How the electricity-price guarantee is measured is not fully specified in the primaries.
- The existing company pledge is not a disclosed contractual remedy in the Theseus announcement.

**Correction (October 14, 2026):** Linked Anthropic’s existing February electricity pledge and distinguished it from a newly specified Theseus contract term.
