Larry Page and Sergey Brin started Google in 1998 as a Stanford research project, then restructured the company in 2015 under a new holding entity called Alphabet to separate the core ad business from experimental bets. Headquartered in Mountain View, the group runs Search, YouTube, Android, Google Cloud, Gemini, DeepMind, and Waymo, generating roughly $350B in annual revenue. Sundar Pichai has led Alphabet as CEO since December 2019. A DOJ antitrust case now threatens forced divestiture of Chrome and parts of the search distribution business.

Equity comp at Alphabet
- 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.

If a meaningful share of your net worth sits in GOOGL, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with GOOGL's option-implied volatility.
Example: 5,000 GOOGL shares at $373.25 is a $1,866,250 position. A 30% drawdown costs $559,875; a 50% drawdown costs $933,125; a 70% drawdown costs $1,306,375. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using GOOGL's option-implied volatility and your cost basis.

Alphabet equity questions
- How much GOOGL 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 GOOGL position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Alphabet grant ISOs, NSOs, or RSUs?
- Equity compensation at Alphabet typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Alphabet RSUs use double-trigger vesting?
- No. Alphabet 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.
