Will AC stop leaking on its own?

No, an air conditioning water leak will never stop, resolve, or fix itself on its own without physical intervention, because the leak is invariably caused by a mechanical obstruction or physical failure that worsens over time. Whether the root cause is a blocked condensate drain line choked with algae slime, a crushed drain hose, a cracked auxiliary drain pan, or a frozen evaporator coil melting excess water, ignoring the issue will only lead to increasing water accumulation, spreading mold growth, and expensive structural damage to your ceilings, walls, and flooring. You can troubleshoot by inspecting the indoor unit for ice and checking drain flow. You can verify that the leak is permanently resolved when clearing clogs, thawing frozen coils, or repairing broken components stops the water flow entirely and keeps your home dry.
