Highlights

•
Opaque commodity markets create opportunity for transparency
Markets like hay and scrap metal lack transparent price discovery and regional liquidity, creating room for data aggregation startups to extract value by making pricing and supply visible.

•
Hay demand is tightening due to broader supply and climate pressures
Global hay demand is outpacing supply due to climate constraints, feed substitution trends, and regional droughts, creating structural price pressure that HayWire tracks and reports on.

Editorial

•
Hay price spikes are eroding the ROI of horse ownership
Rising hay costs are reducing the financial viability of horse ownership, particularly for recreational and small-scale operations that depend on year-round hay purchasing.

•
Networking and relationships are essential to understanding commodity markets
Building HayWire required Johnson and Glasgow to develop relationships with hay farmers, traders, and logistics operators—people who understand how the market actually works on the ground.
