Vertical farming

Grader A: miss

Vertical farms produce leafy greens and herbs at the scale of single plants (about 1 million kg a year for a large facility) and do not supply staple crops. Leading firms failed: AeroFarms filed for Chapter 11 in June 2023 and the UK's Jones Food Company entered administration in April 2025. Share of produce stays far below 5% at the placed year. Provisional, window closes 2031.

Test: Share of produce supply: far below 5%; large facilities produce about 1 million kg a year each.

• AeroFarms (Wikipedia) (2026): AeroFarms filed for Chapter 11 on 8 June 2023, emerged September 2023.
• Vertical farming (Wikipedia) (2026): Large vertical farms produce about 1 million kg of greens a year; Jones Food Company placed into administration April 2025.

Grader B: miss

Vertical farming stayed a small niche with repeated failures. AeroFarms, a sector leader, filed for Chapter 11 in June 2023, and other operators went bankrupt or into administration (Jones Food Company, April 2025). No source shows vertical farms supplying a measurable share of produce. Provisional, window closes 2031.

Test: 20% of the relevant industry (produce supply). Actual: no measurable share of produce; leading firms in bankruptcy 2023-2025.

• AeroFarms (Wikipedia) (2023): AeroFarms filed for Chapter 11 bankruptcy on 8 June 2023 and emerged in September 2023 after restructuring.
• Vertical farming (Wikipedia) (2026): Vertical farms need large start-up funding and some start-ups went bankrupt before profit; Jones Food Company entered administration in April 2025.
