The prediction markets were never about predicting outcomes. If that's the level you are playing on, you're playing at the lowest possible level, and probably won't win.

The markets are now about properly modelling other peoples' manipulation of prediction. That's how Wall Street works as well. Companies can beat earnings and their stocks crash immediately after. It makes zero sense if you just model companies. It makes full sense if you stochastically model how an ensemble of humans behave under incentives and human-written bots behave under human-written policies.

"Hairdryer sometimes get pointed at the weather sensor" and "Government sometimes fudges jobs/CPI data" are more or less the same thing. Build it into your model. That's the level you need to play on to profit in these markets. It's not that different from how a chess engine works.
