All Options is a proprietary options trading firm and market maker headquartered in Amsterdam, the Netherlands. Trading only its own capital, the firm provides continuous two-sided quotes on more than 250,000 listed option instruments across over 800 underlying assets on five European derivatives exchanges. It does not manage money for outside clients or offer any investment product to the public; its business is confined to making markets and taking proprietary trading risk. All Options is founder- and employee-owned, with no external investors, which it says lets it run a longer-term, non-hierarchical structure built around small collaborative trading teams (its stated motto is "we trade as a team") rather than the individual-P&L desk model common at some other options market makers. It is licensed by the Dutch Authority for the Financial Markets (AFM) and supervised by De Nederlandsche Bank (DNB). Its Amsterdam office runs roughly 268 trading screens and employs about 110 people from 21 nationalities, with an average age of around 33. Founded in 1998, All Options is based in a historic building on Kloveniersburgwal in central Amsterdam. Company records list Allard Jakobs as chief executive officer. The firm has since opened a second office in Austin, Texas, through which its US affiliate, All Options USA LLC, a FINRA member, prices options on more than 1,000 US underliers, extending the same proprietary market-making model it has run in Europe since the late 1990s into US options markets.
