Global Vertical Farming Market Size for 2025 Splits Between $6.2B and $9.89B Across Analyst Reports

Findings

• Five industry analyst firms publish 2025 global vertical-farming market-size figures ranging from $6.2 billion (MarketsandMarkets) to $9.89 billion (Polaris Market Research) -- a roughly 60% spread for the same calendar year and the same nominal market.
• Precedence Research ($9.63B) and Polaris Market Research ($9.89B) cluster at the high end, while Fortune Business Insights ($8.52B) and Global Market Insights ($7.4B) sit in the middle, and MarketsandMarkets ($6.2B) is the low outlier.
• The spread likely reflects inconsistent scope: reports differ on whether they count only produce-focused indoor/vertical farms, or also fold in broader controlled-environment-agriculture segments like greenhouse hydroponics, farm-tech hardware, and LED grow-light systems.
• None of the five public report summaries publishes a segment-level revenue breakdown alongside its topline figure, so a reader cannot reconcile the numbers without purchasing each firm's full paid report.
