The claimed 6.8–12.4 billion range matches the three estimates named in the passage, and none of the provided sources addresses those specific estimates. Other sources put glyphosate market value around $7.6–10 billion, inside the claimed range, but they measure market value rather than spending and do not confirm the 12.4 upper bound.

The guest relays this claim without endorsing it. It counts as passed on, not against the post.

This claim is about the present, so it is judged as of the day it was checked.

What was said

… Here we go: worldwide annual spending on glyphosate-based weed killers is roughly seven to 12 billion dollars. Seems well, uhm, is one universally agreed total. Global Market Insight estimates 6.8 billion, Insight 8 estimates 9.3, Transparency Market Research estimates 12.4. These are commercial market estimates, not an audited tally of everyone's purchases, so there's not a clear number, but either way, we're talking about billions. …

What we found

Supports. Market research cited in the sources puts the glyphosate market at about $7.6 billion in 2020, projected to reach $8.9 billion by 2026, and at $8.5–10 billion by 2021; these figures fall inside the claimed 6.8–12.4 billion range.[3][4]

Supports. A 2025 herbicides market report says glyphosate holds 25.5% of a $31.4 billion herbicide market, which implies roughly $8 billion for glyphosate in 2025, also within the claimed range.[5]

Context. None of the sources addresses the three named estimates (6.8, 9.3, 12.4 billion), and the passage itself says these are commercial estimates, not an audited tally of purchases.

Context. The sources measure glyphosate market value or total herbicide expenditure (about $14 billion in 2011, per the EPA via Reuters), not glyphosate-based weed killer spending specifically, so the measures differ from the claim's wording.[1][2][6]
