In short, it lets some current holders sell stock over time. Xanadu said the filing covers up to 293.66 million Class B shares that may be sold by selling holders. That total includes shares tied to Class A share conversion, PIPE shares, founder shares, and warrant shares. That is the main issue for investors. Xanadu had 43.28 million Class B shares listed as of April 2, 2026, before the small warrant share count. So, while the filing does not mean all these shares will be sold right away, it does point to a much larger pool of shares that could weigh on the stock. ### Related Stocks - [XNDU.US](https://longbridge.com/en/quote/XNDU.US.md) ## Related News & Research - [Invezz was right about Xanadu Quantum stock: what comes next?](https://longbridge.com/en/news/285089261.md) - [Xanadu Files F-1, Unlocking Massive Share Sales That Could Pressure XNDU Stock](https://longbridge.com/en/news/284560201.md) - [Xanadu Quantum Computing Craters on Share Listing.
