Abstract: The recently measured $\ensuremath{\gamma}*\ensuremath{\gamma}*\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}$ anomalous form factor is analyzed using the $D4/D8\overline{D8}$ holographic approach to QCD. The half-on-shell transition form factor is vector meson dominated and is shown to exactly tie to the charged-pion form factor. The holographic result compares well with the data for the lowest vector resonance.
