How to use these odds
Treat the top of the table as the market consensus favorite. The real edge is finding teams you rate higher than the market does — a contender priced at 4% that you think is closer to 8% is where prediction-market value lives.
Why markets beat bracket experts
A bracket is one person's snapshot. A market is thousands of traders re-pricing on every injury report, seeding leak, and upset. That's why the live number is the sharpest single read on who's actually favored.
