What Weights & Biases actually allows
Every private-company stock transfer goes through a layer of approval. The company's bylaws and your grant agreement define whether you can sell, to whom, and under what conditions. Most late-stage cos maintain a right of first refusal (ROFR) on any proposed sale; some run quarterly company-approved transfer windows. Weights & Biases has active secondary-market activity, which typically means pre-approved platforms (Forge, EquityZen, Hiive, Nasdaq Private Market) will handle transfers with the company's cooperation.
Tax treatment
A secondary sale of vested RSU-origin shares is a capital gain event with basis equal to the vest-date FMV. For ISO-origin shares, the treatment splits based on holding periods: qualifying dispositions (two years from grant, one year from exercise) produce long-term capital gains on the full spread; disqualifying dispositions treat part of the spread as ordinary income.
The ROFR question
Before you list shares, request the current transfer-restriction language from your stock plan administrator. ROFR periods typically run 30-60 days. Buyer-side pricing in the secondary market already accounts for this wait; plan for the tax event in the quarter the sale actually closes, not when you list.
