Sources indicated on 4 November 2026 that US private sector growth eased in October after a downward revision to the preliminary reading. The Composite Purchasing Managers' Index fell to 55.9 from 58.4 in September, its weakest reading in three months and below the earlier estimate of 57.6.

The revision means the private sector expanded less than previously thought, with both manufacturing output and services activity recording weaker gains in October. reports summarised the release as showing slower momentum across the two main components of the Composite PMI, even as headline expansion remained in place.

Downward revision and its immediate meaning

The October Composite PMI outturn, 55.9, represents a clear reduction from September's 58.4 and sits below the preliminary 57.6 figure announced earlier. That combination of a lower final number and a revision down from the preliminary estimate was described in the report as evidence that expansion in the private sector was not as strong as first reported.

The published summary highlighted that both manufacturing output and services activity showed weaker gains during the month. The report did not amplify those sectoral trends with further component detail beyond noting the relative softening of activity in both areas.

New business remained a bright spot

Despite the softer readings for output and activity, new business continued to rise sharply in October, the report noted, with the services sector providing the primary support for that increase. reports emphasised that strong demand in services underpinned the flow of new work even as other indicators slackened.

The juxtaposition of weaker output gains alongside a sharp pickup in new business points to a mixed picture of demand and capacity in the US private sector for October. The report left open the question of whether services-led order growth will be converted into sustained output increases in coming months.

Market participants and observers will note the final October reading when assessing near-term momentum, given the downward revision from the preliminary estimate. The report's summary of the PMI release provides a snapshot that reduces the degree of optimism conveyed by the initial figure, while still recording expansion overall.

The release, dated 4 November 2026, frames October as a month of slower private sector expansion relative to September, tempered by resilient services demand and continued new business growth. The report's figures and summary therefore portray a private sector that is expanding, but not as briskly as earlier indicated by the preliminary data.
