Recent September ISM Services PMI data at 54.9, down 0.5 points from August amid softer business activity and new orders, anchors trader expectations for the October reading near 54–55. Elevated input costs, with the prices-paid index climbing to 74.0 on fuel, tariffs, and supply-chain strains from Middle East tensions, signal persistent inflation pressures that could cap upside. Employment ticked above 50 for the first time in months while backlogs rose, pointing to resilient domestic demand but limited hiring momentum. With the October report due November 4 and no major seasonal distortions flagged, Polymarket odds cluster tightly around the 54.0–55.9 range, reflecting uncertainty over whether activity moderates further or stabilizes near the 12-month average of 54.1.
