The Atlanta Fed's GDPNow model estimate for real GDP growth in Q3-2025 is 4.0% (saar) today, up from 3.9% on October 27 (chart). After this morning's Manufacturing ISM Report on Business from the Institute for Supply Management, the nowcast of Q3 real gross private domestic investment growth increased from 4.4% to 4.6%. Of course, the model is based solely on data compiled by private-sector sources because the federal government shutdown has cut off the supply of government-reported data since early October.
