| Abstract: In this study, we investigate a comprehensive empirical investigation of Holographic Dark Energy (HDE) models, inspired by the holographic principle that correlates the quantum degrees of freedom within a volume to its enclosing surface. We present an extensive observational investigation of Holographic Dark Energy (HDE) models employing the most recent cosmological probes, including Type Ia Supernovae, Cosmic Chronometers (CC), and DESI DR2 baryon acoustic oscillation (BAO) measurements. Utilizing a Markov Chain Monte Carlo (MCMC) framework, we perform joint parameter estimation for both canonical and interactive HDE models, methodically including uncertainties and correlations across datasets. Current data impose significant limits on the holographic parameter regulating dark energy dynamics, permitting deviations from the conventional cosmological constant model. Our findings indicate that current large-scale structure and distance measurements are already responsive to the unique signals of holographic dark energy in the expansion history. We further demonstrate that forthcoming high-precision large-scale structure surveys will significantly tighten these constraints, providing a robust method to investigate the physical origin of cosmic acceleration within holographically inspired dark energy models.
