Amplify has filed for the Pro Sports Private & Public Ownership ETF ($PROS), a thematic fund tracking publicly traded sports companies alongside select private firms. The filing introduces a hybrid structure designed to provide comprehensive exposure to the professional sports ownership sector. The ETF allocates up to 15% of its portfolio to illiquid private assets, utilizing the regulatory allowance to complete the investment theme. This approach integrates private company exposure within a publicly traded vehicle, offering investors access to both liquid public equities and hard-to-access private sports ownership opportunities.
