In 2011, Arnault launched LVMH "Special Days", the aim of which is to communicate about the expertise of the group. In 2013 he repeated the initiative and doubled the number of workshops open to the public, bringing the total to 42. The objective was to showcase the fact that the technical know-how was continually being passed on from skilled craftsmen unto the next talented generation.
Since 2011, he has been the CEO of Berluti and has worked to develop this LVMH brand through the opening of shops in California, Dubai and New York City. He hired the designer Alessandro Sartori in order to expand from being a colourful shoemaker household to a full-on menswear luxury brand name. Antoine Arnault has invested €100 million in developing the brand and its colourful footwear and classic modern fit clothes.
Since 2011, he has been in a relationship with the Russian model and philanthropist Natalia Vodianova, with whom he has two sons, Maxim, born 2 May 2014, and Roman, born 4 June 2016. Vodianova announced their engagement on 31 December 2019. The COVID-19 pandemic forced the cancellation of their 27 June 2020 wedding at Saint-Pierre d'Hautvillers Abbey, and the couple officially married on 21 June 2020 at a Paris registry office.
