AtmosOption turns every tornado and severe thunderstorm warning into a live market. Read the atmosphere, take a position, and let the storm settle the score.
The second the NWS issues a warning, AtmosOption opens three YES/NO contracts on what the cell will actually do — the gust, the hail, the tornado on the ground. Take a side before the clock runs out; they settle on the verified storm report.
Markets open and settle inside the warning window — the same nowcasting horizon you're already working in lab.
Every market is seeded off live NWS tornado and severe thunderstorm warnings. No invented events, no noise.
No deposits, no risk. Just your read of the atmosphere against everyone else's, scored on what verified.
Track your calibration across a season and find out whether your gut really beats the guidance.
Set up your book, watch the radar, and take a position before the storm does. It's free, it's play money, and it's built for you.
