The big picture
The market's price on Jannik Sinner or Alexander Zverev winning the 2026 US Open crossed to YES today, now reading 61%, having moved 21 points across the window.

On September 8th this brief named Alexander Zverev's chances at 27% YES: the market's price has risen to 61% since, moving 34 points in 4 days. Five of today's biggest movers cluster in the Americas: the North Carolina Senate race, the Sinner-Zverev match market that led today, Zverev-Alcaraz and Zverev-Djokovic matches, and a Federal Reserve hike expectation, now at 66% YES and up 27 points over the month. That rising confidence in a Federal Reserve hike extends the month-long tightening of borrowing costs: the 10-year Treasury is now 4.95%, in the zone where policy reversals have historically occurred, and mortgage rates are at their highest in a year. Consumer sentiment has edged upward to 55 over the month but remains depressed, below the 60 threshold where household spending typically rebounds.

up from 6.69% a month ago, near its highest in the past year.

People filing for unemployment Normal
206k
up from 200k a month ago, in the middle of its range for the past year.
People filing for unemployment is 206k, up from 200k a month ago, and in the middle of its range for the past year. If the recent trend holds, next week it would be near 212k (a trend estimate, not a forecast).

Jobless claims at 206,000 per week track how many people are losing jobs, and when they rise it's often a warning sign for recessions.
