# AMM futarchy reduces state rent costs by 99 percent versus CLOB by eliminating orderbook storage requirements

Central Limit Order Books (CLOBs) in futarchy implementations require 3.75 SOL in state rent per pass/fail market pair on Solana, which cannot be recouped under current architecture. At 3-5 proposals per month, this creates annual costs of 135-225 SOL ($11,475-$19,125 at January 2024 prices). AMMs cost "almost nothing in state rent" because they don't maintain orderbook state—just pool reserves and a price curve.

The MetaDAO proposal notes that while state rent can theoretically be recouped through OpenBook mechanisms, doing so "would require a migration of the current autocrat program," making it impractical for existing deployments.

This cost differential becomes material at scale: a DAO running 50 proposals annually would spend ~$30K-$50K on CLOB state rent versus near-zero for AMMs, creating strong economic pressure toward AMM adoption independent of other mechanism considerations.

## Evidence
- MetaDAO proposal documents 3.75 SOL state rent cost per CLOB market pair
- Annual projection: 135-225 SOL for 3-5 monthly proposals
- AMM state requirements described as "almost nothing"
- State rent recovery requires autocrat program migration (feedback section)

MetaDAO proposal CF9QUBS251FnNGZHLJ4WbB2CVRi5BtqJbCqMi47NX1PG quantifies the cost reduction: CLOB market pairs cost 3.75 SOL in state rent per proposal (135-225 SOL annually at 3-5 proposals/month), while AMMs cost 'almost nothing' in state rent. At January 2024 SOL prices ($85), this represents $11,475-$19,125 annual savings.

Proposal 5 quantified the cost: CLOB pairs cost 3.75 SOL in state rent per proposal, which cannot be recouped. At 3-5 proposals/month, annual costs were 135-225 SOL ($11,475-$19,125 at then-current prices). AMMs cost 'almost nothing in state rent.' This is the specific cost basis for the 99% reduction claim.
