How a Vibecoded Newsletter Is Making the Hay Market More Transparent

What It Covers

Aidan Johnson, a 20-year-old college basketball player, built Haywire — an AI-powered newsletter aggregating USDA auction data to bring price transparency to the $8 billion U.S. hay market, a fragmented commodity with no standardized benchmark and prices currently at $180 per ton for hay and $185 for alfalfa.

Key Questions Answered

• •Public data arbitrage: The USDA publishes weekly hay auction prices by region, bale type, weight, and quality — buried in PDFs almost nobody reads. Aggregating this via direct API integration and presenting it in plain-English newsletters creates immediate value. Any niche market with ignored government data reports represents a similar opportunity for a lean, two-person operation.
• •Hyperlocal commodity pricing: U.S. hay prices cannot be tracked as a single national figure. Transportation costs of $5–$8 per mile make cross-regional shipping economically unviable, meaning regional prices diverge sharply. Buyers and sellers should benchmark against their nearest auction house — such as Rock Valley, Iowa — rather than national USDA averages, which mask local supply-demand conditions.
• •Drought-driven demand migration: 46% of U.S. alfalfa acreage is currently in drought conditions, pushing buyers in Western states to source from Midwest auction houses. Haywire tracked this pattern — dubbed the Missouri Pattern — by monitoring sequential weekly price spikes moving eastward, demonstrating that regional price anomalies can signal broader supply stress before it becomes widely reported.
• •Quality tiers determine end-use: Hay is graded by Relative Feed Value (RFV), indexed at 100 as baseline. Dairies and horse owners purchase premium alfalfa above RFV 150 for high protein and leaf content. Beef operations use lower-grade, drier hay with less leaf content. Understanding which quality tier applies to your operation determines which regional auction data is actually relevant for purchasing decisions.
• •AI-enabled niche media business model: Haywire operates with two people by automating data ingestion, cross-referencing, and newsletter generation using agentic AI tools. A free tier builds audience; a pro subscription runs $14 per month, rising to $17 after June 30. This cost structure — previously requiring a full editorial team — is now viable at small subscriber counts, making dozens of similarly opaque commodity markets addressable.
