Prediction markets went from niche to mainstream fast. Kalshi's event contracts now trade serious volume on everything from Fed decisions to football games, and a growing number of traders treat them exactly like any other instrument: with positions, sizing, entries, exits, and P&L.
What they didn't have was a journal. Every trading journal on the market assumes your trades are stocks, options, futures, or crypto. Event contracts didn't fit, so prediction market traders tracked their YES/NO positions in spreadsheets, or worse, not at all.
TradeZap 5.5 fixes that. It's the first trading journal with prediction markets support.
Journal Kalshi Event Contracts Like Any Other Trade
Prediction markets are now a first-class asset class in TradeZap, alongside stocks, options, futures, and crypto. Log a Kalshi position the same way you'd log a stock trade:
- YES/NO positions. Record which side you took and how many contracts.
- Entry prices. Event contracts trade between $0.01 and $0.99, and your entry price is your implied probability. TradeZap records it like any other cost basis.
- Resolutions. When the market settles at $1.00 or $0.00, log the outcome and your realized P&L flows into every stat you already use: win rate, expectancy, profit factor, the P&L calendar, all of it.
Your event contracts live in the same trade history, same calendar, and same analytics as the rest of your trading. One app, five asset classes.
Market Categories: See Where Your Edge Actually Is
Here's the thing about prediction markets: they're not one market. Being good at pricing NFL games has nothing to do with being good at pricing CPI prints. Most prediction market traders have a category edge and don't know it, because their P&L is one blended number.
5.5 introduces market category tags: Sports, Politics, Economics, and Crypto. Tag each market when you log it, and TradeZap breaks down your P&L by category. The picture that emerges is often blunt: up in sports, flat in economics, bleeding in politics. That's an actionable finding you can't get from your Kalshi account screen.
Aura Understands Prediction Markets
Aura, TradeZap's AI trading coach, treats event contracts as real trades, because they are. Ask her the same kinds of questions you'd ask about your stock trading:
- "How's my prediction market performance this month?"
- "Which market category am I actually profitable in?"
- "Do I do better on YES or NO positions?"
- "How do my event contracts compare to my options trading?"
She answers with numbers from your actual history, the same way she does for every other asset class. If you're overconfident in politics markets and don't know it, Aura will be the one to tell you.
Why Journal Prediction Markets at All?
The case is the same as for any instrument, maybe stronger. Event contracts are binary: you're either right or wrong, and your long-run P&L is a direct readout of whether your probability estimates beat the market's. Without a journal, every settled contract disappears into a vague memory of "doing okay." With one, you learn your calibration: which categories you read well, what position sizes you handle, and whether that Sunday parlay energy is helping or hurting.
Discipline compounds. That's the whole thesis of TradeZap, and it applies to a CPI contract exactly as much as to a covered call.
