We present a sub-2% measurement of the Hubble constant that is independent of this scale, using data from the first data release of the Dark Energy Spectroscopic Instrument (DESI DR1). Building on previous work, we remove dependency on the sound horizon size using a heuristic rescaling procedure at the power spectrum level. A key innovation is the inclusion of uncalibrated (agnostic to rs ) post-reconstruction BAO measurements from DESI DR1, as well as using the CMB acoustic scale θ * as a high-redshift anchor. Uncalibrated type-Ia supernovae are often included as an independent source of Ωm information; here we demonstrate the robustness of our results by additionally considering two supernova-independent alternative datasets. We find somewhat higher values of H 0 relative to our previous...
