Pacific Fusion: Milestone-Based Series A Capital Deployment Schedule
| Tranche | Milestone Trigger | Capital Released | Target Date | |
|---|---|---|---|---|
| Tranche 1 (immediate) | Series A close + initial capital deployment | ~$200M (estimated of $900M total commitment) | Oct 2024 (closed) | |
| Tranche 2 | Lab-scale physics validation + first major scientific milestone | Not disclosed specifically; estimated ~$200M | Target 2026 | |
| Tranche 3 | Sub-scale device construction + first operations | Not disclosed specifically; estimated ~$250M | Target 2027-2028 | |
| Tranche 4 | Sub-scale demonstration of fusion conditions | Not disclosed specifically; estimated ~$250M | Target 2029 | |
| Total Series A commitment | Total capital pool subject to milestone achievement | $900M (largest single fusion round in industry history) | Cumulative deployment 2024-2029+ | |
| Sub-scale fusion demonstration target | Pacific Fusion-stated scientific milestone | N/A (operational milestone) | Target 2030 | |
| Commercial demonstration target | Pacific Fusion-stated commercial roadmap | N/A (commercial milestone) | Target 2032 (slipped from original 2030) | |
| Editorial. Why this matters | Strategic context | Pacific Fusion's milestone-based Series A is structurally unique among fusion financings. Most fusion rounds are flat-tranche commitments; Pacific Fusion's milestone-gated approach reflects sophisticated VC underwriting of a high-risk technical bet. Marquee question: as Pacific Fusion executes against milestones, does the company access subsequent tranches on schedule, or do milestone-gate slips delay tranche releases + slow the commercial demonstration roadmap further? |
