Week in Review: the Senate control gap flips toward Democrats, Texas swings 9 points

The calendar

No rates or polls events resolve in the next 14 days. The board ahead is college football: Indiana at Northwestern (market has Indiana 92.5%) and Louisville at Wake Forest (Louisville 83%) on Sep 25-26, plus lopsided lines on Texas Tech (99.5%) and Miami FL (99.5%). Sports and commodity markets settle continuously (see the desk sections).

Market vs. fair value
