With a budget of about ten million Swiss francs, Weltklasse Zürich ranks among the most expensive events in athletics.

[11] Other sponsors are Vaudoise Assurances, Migros, Le Gruyère Switzerland, Medica, Omega, Swiss, Lexus, Erdgas and Puma.

[13] During 2020 the COVID-19 pandemic prevented Weltklasse Zürich from taking place, instead an event called Inspiration Games was held.

[25][13] The number of lanes was increased to eight in the early 1970s which forced the Weltklasse to be put on hold for two years for the construction to take place.

[27][28][29] The new surface was installed in June 2014 at a cost of 800,000 CHF and was paid for by the city of Zurich, which owns Letzigrund Stadium.
