Methodology & Data Sources
Yellowcake Analytics is an independent uranium- and nuclear-market data site. Our goal is to make institutional-grade uranium data legible to everyone — and to be transparent about where every figure comes from and how reliable it is. This page documents our sources and the provenance system applied across the site.
Where our data comes from
Uranium spot price (headline)
An independent, published on-chain U₃O₈ spot feed, with a physical-uranium-trust NAV-implied cross-check. The headline is the live value of the Yellowcake Composite below.
Price history — the Yellowcake Composite
The site shows ONE price series. Where a live published spot print exists, the composite is that print (real). From July 2007 until the live-feed era it is our own derived daily estimate: a weighted blend of a specialist daily spot indication and a physical-uranium-trust-implied price, with its trailing 20-day median basis removed and quantized to a $0.05 grid — labeled estimated, and validated against the live feed (121-day overlap: mean −$0.01, σ $0.85). Before 2007, long-range charts use an official public monthly reference series. Third-party inputs are used only as model inputs under their terms and are never republished raw.
Long-term (term) price
Publicly reported month-end term price levels, shown as monthly context and attributed where displayed.
Physical uranium trust
A publicly-traded physical uranium trust — holdings, net asset value, and units outstanding as published by the trust — used for the NAV-implied cross-check.
Equity prices & market caps
Multiple third-party market-data providers for quotes; a third-party fundamentals provider for shares outstanding and exchange listings used to compute market capitalization.
Dividends & analyst price targets
Third-party fundamentals data — forward dividend yield and the consensus analyst target price shown on individual stock pages. Analyst targets are aggregated third-party estimates, not forecasts by Yellowcake.
Company uranium resources & AISC
Company disclosures prepared under NI 43-101, JORC, or SEC S-K 1300 (technical reports, annual and quarterly reports). Figures are machine-extracted from the filings with LLM assistance, carry a link to the source document, and are refreshed as new filings appear.
SEC filings
SEC EDGAR full-text and submissions API.
Reactor fleet, supply & demand
World Nuclear Association and IAEA PRIS, supplemented by company production guidance.
Nuclear map — reactor sites
Global Energy Monitor, Global Nuclear Power Tracker, September 2025 release, used under CC BY 4.0 (plant locations, unit statuses, capacities, grid-connection and retirement years).
Nuclear map — mine production & country data
World Nuclear Association public tables (World Uranium Mining Production; Uranium Production by Country; World Nuclear Power Reactors & Uranium Requirements; Supply of Uranium per the OECD-NEA/IAEA Red Book), cited per figure.
Nuclear map — fuel-cycle facilities
WNA fuel-cycle pages (conversion, enrichment, fuel fabrication) and operator disclosures; capacities are licensed/nameplate figures as published.
Nuclear map — EU import flows
Eurostat Comext monthly extra-EU trade (HS 2844.10, 2844.20, 2612.10), the same live source as the import monitor.
Nuclear map — US facility statuses
Cross-checked against the EIA Domestic Uranium Production Report (annual) and USGS Fact Sheet 2025–3057 (April 2026, doi.org/10.3133/fs20253057).
Nuclear map — scope reference
EPA Uranium Location Database (EPA 402-R-05-009): ~15,000 legacy US uranium locations documented; the map tracks the modern investor-relevant fleet, not the legacy inventory.
Provenance: how we label every figure
Headline figures across the site carry a badge describing how they were produced; derived figures (averages, ratios, chart annotations) inherit the provenance of the inputs shown alongside them. We would rather show you a transparent estimate than a confident-looking number with no lineage.
Real
Taken directly from a primary source — a price feed, an exchange quote, or a regulatory filing — with no transformation beyond formatting.
Estimated
Derived from real inputs using a disclosed calculation (for example a NAV-implied spot price), where some assumption is involved.
Modeled
Produced by one of our forward models (for example a demand projection). Clearly the most uncertain category and labeled as such.
