Estimates only. Excludes disqualifying dispositions, NSOs, multi-state moves, and AMT preferences other than ISO bargain elements. Long-term capital gains tax assumes a qualifying disposition (ISO held ≥1 yr from exercise and ≥2 yr from grant); state LTCG follows ordinary brackets except where the state grants preferential treatment (HI, ND, SC, WI, AR, NM) or has a dedicated LTCG-only tax (WA). Assumes you are within the $100K ISO limit (any portion of an annual ISO grant whose FMV at grant exceeds $100K is treated as NSO from the start, §422(d)). State AMT figures are 2025 (next-year values published in late 2026). Not financial advice.
QSBS note. If your shares qualify (typically pre-IPO C-corp grants held 5+ years), a federal rule lets you exclude up to $10M of gain on a future sale from federal tax. That single rule shifts exercise-timing math more than AMT does. (This is §1202 “qualified small-business stock”.) Modeled in beta, not here.
You optimized one grant in isolation. The beta optimizes ISOs alongside your RSUs, NSOs, and stock in one plan.

Spun out of Harvard University's quantum computing lab in 2017, Zapata Quantum builds hardware-agnostic software for quantum computers. Founded by Harvard professor Alan Aspuru-Guzik, four of his postdoctoral researchers, and CEO Christopher Savoie, the company developed the Orquestra platform and holds patents for Quantum Intermediate Representation (QIR), a translation layer that lets quantum programs run across multiple hardware platforms. After ceasing operations in October 2024 and filing for bankruptcy, the company relaunched under CEO Sumit Kapur and closed an oversubscribed $15 million financing round in April 2026.

Equity comp at Zapata Quantum, Inc.
- Zapata Quantum completed a SPAC merger in March 2024 when Andretti Acquisition Corp. merged with Zapata Computing, Inc. and domesticated as a Delaware corporation. The company ceased operations in October 2024 due to debt obligations, filed for bankruptcy in 2025, and re-emerged as Zapata Quantum focused on quantum software after converting over $10 million of debt to equity. Pre-restructuring equity plans were substantially disrupted by the bankruptcy. As of year-end 2025, total unrecognized stock option compensation was approximately $1,849, indicating minimal active grants. The company has used stock options rather than RSUs as its primary equity vehicle both before and after restructuring.
- Vesting schedule: stock options vest monthly over four years with a one-year cliff on initial grants.

Zapata Quantum, Inc. equity questions
- How much alternative minimum tax (AMT) will I owe exercising Zapata Quantum, Inc. ISOs?
- Exercising incentive stock options (ISOs) does not create regular income tax, but the bargain element (the fair market value at exercise minus your strike price) counts toward the alternative minimum tax (AMT). The amount depends on the bargain element, your other income, your filing status, and your state. The calculator above models federal and state AMT, the AMT crossover point, and how the credit recovers in later years for your exact Zapata Quantum, Inc. figures.
- Does Zapata Quantum, Inc. grant ISOs, NSOs, or RSUs?
- Equity compensation at Zapata Quantum, Inc. typically takes the form of incentive stock options (ISOs) and non-qualified stock options (NSOs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise.
- Are Zapata Quantum, Inc. shares eligible for QSBS?
- They might be. Qualified small business stock (QSBS) under Internal Revenue Code Section 1202 can exclude federal tax on much of the gain when shares were acquired at original issuance from a C-corporation while its gross assets were under $50 million, and held at least five years. Whether your Zapata Quantum, Inc. shares qualify turns on when you acquired them and the company's asset size at that time.
