📉 Cumulative realized P&L
Cumulative realized P&L · Polymarket + Kalshi · Oct 3–31, 2026 · held to resolution
Running total across all 84 resolved markets on both platforms, grouped by the day each result landed. Amber diamonds mark deposits — Polymarket US: $10 on Oct 3, $10 on Oct 6, $100 on Oct 13; Kalshi: $100 on Oct 13 — cash added to the balances, not profit, so the line itself doesn't step on those days. Deposits funded the book — the line tracks forecasting results only.
Daily P&L
Resolved P&L by day · stacked by platform · Oct 3–31, 2026
Polymarket
Kalshi
One bar per day, built from the same resolved results listed below. Each platform's segment stacks from the zero line in the direction of its own sign — gains up, losses down — so each bar shows the day's split and its net. Hover or tap a bar for the day's figures.
