Blind pool is a term frequently used in the finance industry to describe an investment fund whose portfolio is unknown to investors. It is also known as a blank-check company or a special purpose acquisition company. Blind pools are used by institutional investors to raise capital from the public and take over an existing company, or to fund an acquisition, merger, or other business combination. Synonyms for blind pool include shell company, zero-revenue company, and pre-IPO company. Blind pool investments are high-risk, high-reward opportunities for investors, and they must have a high risk tolerance to participate. Overall, blind pool investments allow investors to bet on the reputation and expertise of the fund manager to generate attractive returns.
