Cornerstone Investor

A cornerstone investor is a large, reputable investor who commits to an IPO early and publicly, anchoring confidence in the offering.

The cornerstone concept, prominent in markets like Hong Kong, is broadly analogous to the anchor investor role in Indian IPOs: a marquee institution commits a sizeable amount before the public issue, lending credibility. The investor's commitment and lock-in are disclosed in the offer document.

While India formally uses the 'anchor investor' framework rather than the cornerstone label, the term appears in cross-border deals and global coverage. Both serve to validate pricing and demand ahead of the public offering.
