Real-money markets do have stronger incentives for sharps to scour for arbitrage, so the 1/1/26 market would have been more likely to be noticed before months had gone by.
However (depending on the fee structure for resolving N/A markets), real-money markets have even stronger incentives for sharps to stay away entirely from spurious conditional markets, since they’d be throwing away cash and not just Internet points. Never ever ever cite out-of-the-money conditional markets.
Yes, and I gained some easy mana from such markets; but the market that got the most attention by far was the intrinsically flawed conditional market.
