Predict for Profit is a tools platform for Kalshi traders — fee-honest calculators, market monitoring, resolution rules, and a disciplined trading journal. No picks, no gurus. Software and education, not trading advice.
Five calculators — Fees, EV, Devig, Kelly, and Exit Ladder. Every number is fee-honest to the cent and computed instantly in your browser. Plan an exit ladder across up to eight rungs and see the blended P&L before you're in the trade.
Scan any Kalshi event for pricing incoherence — buy-the-field and sell-the-field dislocations, ladder monotonicity — with fees subtracted before anything is called tradeable. If the edge disappears after fees, we say so.
Every new Kalshi series and event, surfaced as our monitor detects it, with category and kind filters. Be early to new markets instead of hearing about them after the edge is gone.
Curated settlement rules for major series — the settlement source, the timing conventions, and the edge cases that decide whether you actually won. Read the rules before the market does.
Organize positions by belief, not chronology. Four positions expressing one belief aren't four trades — they're one bet, and your journal should say so. Fee-honest cost basis and realized P&L per position, rolled up per thesis.
