Start from your key markets, not from Wikipedia's rankings of largest editions. The language versions that matter are the ones your customers, regulators, investors, and journalists actually read: the languages of your biggest revenue markets, plus anywhere you are hiring, listing shares, or seeking government approvals. For most multinationals that produces a short list, usually some mix of English, German, French, Spanish, Japanese, and a few others specific to the business.
But there are other considerations, too:
For going by size, use traffic statistics, not article counts. A few Wikipedia editions are much larger than their actual speaker bases would imply. In recent years, Wikipedia editors at the Swedish and Cebuano Wikipedias have used machine translations to adapt pages mostly from the English Wikipedia.
Also remember that AI tools answer in the user's language, drawing on sources in that language, so the German article shapes what a German-speaking user hears about you. (And oftentimes they will pull from the English Wikipedia as well.)
One special case: Wikipedia has been blocked in mainland China since 2019, so the Chinese-language version mainly reaches Taiwan, Hong Kong, and Chinese speakers abroad, while perception inside mainland China runs through websites only written and read within the country itself.
Also useful to know: some wealthy countries do most of their Wikipedia reading in English. For the Nordic countries and much of the Gulf, the English article plus the local version is the real target, not the local version alone. Likewise, just as English is the business language of India, the subcontinent relies primarily on the English Wikipedia.
