4-bullet brief | narrative

Ladder pricing implies September U-3 in the 4.2-4.3% range: 54% above 4.2%, 37% above 4.3%, dropping sharply to 12% above 4.4%.
The CBS analysis highlights broader labor underutilization, but prediction markets are priced off the official BLS U-3 measure, not alternative metrics.
The 65% probability above 4.1% signals modest upward drift from July's reading is the consensus, not a sharp deterioration.
Resolution tied to BLS official U-3; alternative unemployment definitions cited in the CBS report do not affect contract settlement.
