AltStreet Analysis

Generated from EDGAR primary sources

Bighorn Carbon Fund, LLC filed an original Form D on June 8, 2026, in pre-open status with no capital raised or investors disclosed. The filing claims multiple exemptions (506(b), 506(c), Rule 504, and 4(a)(5)) simultaneously. This is a carbon and climate-focused investment vehicle with no minimum investment or first sale date disclosed.

Carbon and climate investment vehicles typically file under 506(b) or 506(c) for institutional or accredited investor raises. The simultaneous claim of four exemptions—including Rule 504 (small offerings under $10M) and 4(a)(5) (unregistered securities)—alongside the more common 506 exemptions is atypical and suggests either a complex multi-tranche structure or potential filing error.
