Case Study

A tale of two startups trying to launch a decentralized sports betting platform.

Startup A: "DeFi Bet" (The AMM Fork)

Tech Stack: Forked a standard LMSR (AMM style) on Polygon.

• The Launch: Users deposited USDC into a pool.

• The Game: "Lakers vs Warriors". Users swapped "USDC" for "LakersToken".

• The Problem:

  1. Impermanent Loss: Liquidity providers lost money when the Lakers won (the pool became unbalanced). LPs pulled liquidity.

  2. Slippage: A user tried to bet $10k. The pool only had $50k. Slippage was 20%. The user left.

  3. Speed: Live betting was impossible because transactions took 5 seconds to confirm.

• Result: Shutdown after 3 months due to lack of volume and LP losses.

Startup B: "ProTrade Sports" (The Orderbook Integration)

Tech Stack: [Orderbook.trade](https://www.orderbook.trade/) SaaS + Custom React Frontend.

• The Launch: Integrated the Orderbook API in 2 weeks.

• The Game: "Lakers vs Warriors" Binary Market (0 to 100).

• The Solution:

  1. CLOB: Market Makers quoted tight spreads (Buy Yes @ 0.45, Sell Yes @ 0.55). No Impermanent Loss concept.

  2. Depth: A $10k bet was matched instantly against resting limit orders with < 0.1% slippage.

  3. Speed: "Fast-Bet" feature allowed instant off-chain matching.

• Result: $10M Volume in Month 1. Now the leading sports prediction market.

Key Takeaway

For outcomes with expirations (like sports or derivatives)

AMMs mathematically fail. Only an Orderbook (CLOB) can handle the risk/reward structure correctly.
