This loan shouldn't be possible (Ad)

On May 21, 2026, a federal board unanimously approved a roughly 3 billion dollar loan to a single American mining company - a sum larger than the company's entire current market cap. The people with access to the drill reports, projections, and internal data decided this business deserves more capital than Wall Street currently assigns it. The paperwork is set to be finalized later this year. One valuation is wrong. See which one before the correction happens.tc pixel
