MATERIALLY INCOMPLETE HISTORY: TAE has raised over $1.3B across ~11-12 rounds since inception; public reporting on most early rounds is thin. BIGGER PICTURE: on Dec 18 2025, Trump Media & Technology Group (DJT) announced a ~$6B all-stock merger with TAE to create the first publicly traded fusion-power company (expected to close mid-2026) — a going-public event via reverse merger, not a conventional IPO, that supersedes any standalone private valuation as the relevant framework going forward. If the (unverified) $7.25B 2022 mark is accurate, TAE's private valuation fell ~66% by 2025 — a flag worth independent verification.

IPO year/valuation predictions are on the roadmap but not live yet — we want a real, defensible methodology (funding-round deceleration, revenue growth, IPO market conditions, comparable-company patterns, etc.) before showing numbers here, not just a guess.
Transparent, formula-based composite (not machine-learned) of five signals: raise velocity, round acceleration, secondary premium/discount vs. the last primary round, up-round streak, and freshness of the last known mark.
