What you actually hold at Mistral AI

Most Mistral employees in France hold BSPCE (bons de souscription de parts de créateur d’entreprise) — warrants that let you subscribe for shares at a set price, with a favourable French tax regime. Some staff (for example outside France, or who don’t qualify) may hold ordinary options or RSUs instead. You exercise BSPCE or options into shares before you can sell. Check your grant for which instrument you hold, your strike and vesting.

How Mistral AI equity turns into cash

Mistral is private, with no open market. Liquidity has come mainly with its funding rounds (which can include some secondary selling) rather than a regular tender. Outside those, selling is subject to Mistral’s transfer rules. Don’t assume a tender window on a fixed schedule.

The decision you’re probably facing

BSPCE is the detail that changes everything. If you hold BSPCE, your instrument and tax are French-specific — not the US option/RSU playbook. There’s a favourable flat-tax regime, but it can be less favourable if you leave within three years of the grant. Confirm you hold BSPCE (not ordinary options) before you plan.

The practical steps: confirm your instrument, value your vested BSPCE at the latest round minus your strike, and check the French tax of exercising and selling.

The tax reality (France)

French BSPCE have their own regime. The gain between your strike and the sale price is generally taxed under a flat regime (the prélèvement forfaitaire unique, around 30% including social levies) when you sell, with a higher rate possible if you leave within three years of the grant. Ordinary options or RSUs are taxed differently. Take French tax advice; see our methodology.

What to expect on price

A tender has a set price; a private secondary to an outside buyer usually happens at a discount to the last headline valuation — because the buyer takes an illiquid minority stake, and you likely hold common shares worth less than investors’ preferred. See what discount is fair.

Is Mistral going public?

No IPO has been confirmed as of November 2026. For now, liquidity depends mainly on funding rounds and Mistral’s own arrangements.

Do I need Mistral AI's approval to sell my shares?

Almost always, yes. Mistral AI, like most private companies, controls share transfers through a right of first refusal, transfer restrictions and board or company approval written into your equity documents. No marketplace or buyer can override that. Start by reading your grant and shareholder agreements and asking Mistral AI's stock administration what is permitted.

What tax will I pay when I sell Mistral AI shares or stock?

It depends on where you live and what you hold. In the United States, selling settled shares usually triggers capital-gains tax, and exercising options first can create a separate taxable event (including AMT on ISOs). In Europe the treatment varies by country. This is general information, not tax advice — confirm your own position with a qualified adviser before you sell.
