Peter Peterson and Stephen Schwarzman founded the firm in 1985 with $400,000, starting in advisory before raising its first buyout fund. It is now the largest alternative asset manager, with real estate the biggest segment, alongside private equity, credit, and hedge fund solutions. The 2007 listing was among the first for a private equity firm, and the 2019 conversion from partnership to corporation broadened its investor base. Fee-related earnings from permanent capital vehicles have become the emphasis. Headquarters are in New York City.

Equity comp at Blackstone
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

Blackstone equity questions
- How much BX stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your BX position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Blackstone grant ISOs, NSOs, or RSUs?
- Equity compensation at Blackstone typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Blackstone RSUs use double-trigger vesting?
- No. Blackstone restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
