How It Works

You have a thesis about the world. SimpleFunctions turns it into a trading system.

1

Write your thesis

“The US-Iran war will persist. Hormuz stays closed. Oil stays above $100. SPR can't compensate. The Fed is trapped between inflation and recession.”

Plain text. No special format. Write what you believe and why.

2

Causal tree

The system decomposes your thesis into a tree of verifiable assumptions:

causal tree — f582bf76
  n1  War persists ........................ 88%
    n1.1  US initiated strikes .......... 99%
    n1.2  Iran continues retaliation .... 85%
    n1.3  No diplomatic exit ............ 82%
  n2  Hormuz blocked .................... 97%
    n2.1  Mines deployed ................ 99%
    n2.2  IRGC small craft active ....... 90%
    n2.3  Minesweeping takes 3+ months .. 87%
  n3  Oil stays elevated ................ 64%
  n4  Recession ........................... 45%

Each node has a probability. Nodes are causally linked — when upstream nodes change, downstream nodes update.

Edge detection

The system scans Kalshi and Polymarket for contracts related to your causal tree. For each contract, it calculates:

Thesis price

What the contract should be worth if your thesis is correct

Market price

What it actually trades at

Edge

Thesis price − market price

Executable edge

Edge minus orderbook spread

edge analysis
  Recession 2026 YES    market 35¢   thesis 72¢   edge +37   spread 1¢   high liquidity
  WTI $150 YES          market 38¢   thesis 75¢   edge +37   spread 1¢   high liquidity
  Gas $4.50 Mar YES     market 14¢   thesis 55¢   edge +41   spread 3¢   med liquidity

This means: the market thinks recession is 35% likely. Your thesis thinks it's 72%. If you're right, this contract is massively underpriced.
