Backtests can be tuned. A forward ledger cannot: each position below was opened by the rex engine in real time and settled against the market's actual on-chain outcome. Losses included, always.
| market | strategy | entry | stake | result | date |
|---|
| strategy | oos hit | 95% CI | edge | roi/bet | n |
|---|---|---|---|---|---|
| Bedrock | 93.3% | 91–95% | +3.6pts | +13.6% | 451 |
| Keystone | 92.4% | 90–94% | +3.9pts | +15.3% | 471 |
| Vanguard | 90.4% | 88–93% | +3.4pts | +13.7% | 539 |
Don't trust the page — check the math. The settled ledger is published as canonical JSON and fingerprinted daily; past fingerprints are never edited.
Reproduce it: curl -s https://rex-income.vercel.app/ledger/ledger.json | shasum -a 256 — then match it against the append-only daily timeline at /ledger/hashes.json (5 days recorded). Every verdict carries its Polymarket conditionId, so each outcome is independently checkable on-chain. And because nobody publishes their failures: the losses page — every losing position, permanently public.
Methodology: positions are sized with fractional Kelly from each strategy's out-of-sample, ground-truth backtest (survivorship-bias-free — full methodology on the home page). Paper money; verdicts settle against gamma-api resolved outcomes. This page regenerates automatically from the engine's ledger. Past performance does not guarantee future results. Not financial advice. Snapshot: 2026-06-22 19:57 UTC.
