Most indicators suggest growth in output, spending aggregates (while employment is trending sideways). Housing is suggested as a leading indicator by Leamer (2007, 2015), but less a leading indicator recently (Green, 2022). Here’s a picture of residential fixed investment, which on average leads economic activity by approximately 7 quarters:

GDPNow has residential investment as flat in Q4, and below the November SPF trajectory.

On the other hand, some people claim “AI is the new housing” (here). I will note that over the 1986-2025 period (omitting the pandemic period, 2020-2022), residential investment appears to Granger cause GDP, while the reverse does not appear to be the case (at 5% msl).
