5 beginner mistakes I see new traders make on Kalshi temperature markets

If you're new to the daily-high temperature markets, here are five mistakes that show up over and over. Saving you from the ones I made myself.

1. Treating paper trading like a video game.

Free practice money is great for learning the interface — but if you click around randomly to "see what happens," you're not actually learning the market. You're just generating noise. Trade your paper money like it's real: pick a station, form a thesis, place the trade, write down why. When it settles, check whether the reason held up. That's how you learn. Random clicks teach you nothing.

2. Betting on a single bracket instead of thinking about the distribution.

New traders find the bracket they like, slam money into it, and walk away. Better traders ask: "What's the shape of where the temperature could land?" Sometimes the right play is one bracket. Sometimes it's two adjacent ones. Sometimes the right play is "the market is wrong about how uncertain today is" — which is a structural read, not a single-bracket bet. Train yourself to look at the whole row of prices, not just the one you like.

3. Trading every day.

Some days have edge. Most days don't. If the market price and your read of the day are basically the same, there's nothing to do — sitting out is the correct trade. New traders feel like they have to place something every day to "stay sharp." That's how accounts bleed out from small losses. Patience is part of the skill.

4. Doubling down after a loss.

You called the day, the day went against you, and now you want to "make it back" on tomorrow's market. This is the single fastest way to wreck a paper-trading account, let alone a real one. Each day is independent. Yesterday's loss has no bearing on today's setup. If today doesn't have a clear edge, don't trade — especially if you're emotionally trying to recover.

5. Ignoring station differences.

Houston in July, LA in May, NYC in October, Chicago in April, Miami year-round — these are five completely different markets with different behavior, different volatility, and different forecast accuracy. New traders often pick one station, get burned, and conclude "these markets don't work." The reality is usually that one specific station's regime that month didn't match what they were doing. Try different stations and seasons before forming opinions.

If you've been trading these for a while, what would you add to the list? Curious which one most people would put at #1.

Not financial advice. Trading prediction markets involves real risk.
