You can trade prediction markets on elections, sports, the economy - all sorts of things. We picked one quiet corner and stayed there: daily temperature. Here's why that corner is so good, and why we only ever take one side of it.
Three reasons temperature is a sweet spot
1. It settles fast. A "high temperature today" market is decided by tonight. You're not waiting months for an election - you find out the same or the next day, and your money is free again.
2. There's a real forecast. Unlike "who wins the game," the weather is something the world's supercomputers genuinely predict well a day or two out. There's actual science to lean on.
3. It's often mispriced. This is the big one. Casual traders love an exciting story - "it's gonna be a scorcher, it'll hit 100!" - and they pile onto the dramatic side. That leaves the boring, more-likely side priced too cheap.
The boring side is the profitable side
Picture a city forecast to top out at 88°F. Now picture a market asking, "Will it hit 95°F or higher today?" The honest answer is almost certainly no - but because a few people are dreaming of a record-breaker, the YES side gets bid up, and the NO side ends up trading at, say, 92¢.
If we're confident the day stays well under 95°, buying NO at 92¢ to collect $1 is a strong, high-probability trade. We're not predicting the exact temperature - we're just confident it won't reach an extreme. That's a much easier call to get right.
Our edge isn't "better weather forecasting"
We're not trying to out-forecast the National Weather Service. The edge is the gap between a good forecast and a slow-to-react market. Two things create it:
First, prediction-market prices often lag the latest model runs by hours - so a forecast can shift while the price hasn't caught up yet. Second, retail traders chase longshots and manage risk poorly, which leaves consistent mispricing on the safe side.
The forecast is the gate - it tells us whether a market is safe enough to touch. The mispricing is the edge - it tells us whether there's money in it.
That's why most days are quiet
A signal only fires when several things line up at once: a wide safety margin, agreement across our weather models, and a real pricing gap. Most days, across 40+ cities, nothing clears the bar - and we'd much rather send you nothing than send you a weak trade. Quality over volume, every time.
