Toplu Konut İdaresi tarafından yaptırılan ve 2017'de tamamlanan stadyum adını Mustafa Kemal'in Samsun'a çıktığı gün olan 19 Mayıs'tan almaktadır. İlk olarak Nisan 2011'de duyurulan proje 3 Aralık 2012'de Toplu Konut İdaresince yapılan ve Ali Acar İnşaat'ın kazandığı ihale ile resmiyete dökülmüş, 4 Ağustos 2013 tarihindeki temel atma töreni ile de inşa aşamasına geçilmiştir. İnşaatın başlangıç tarihinden itibaren en geç 800 gün içerisinde tamamlanması taahhüt edilse de UEFA'nın standartlarına uyum sağlamak için projede yenileme yapılması, çatının inşasıyla sorumlu şirketin iflas etmesi gibi sebeplerle tamamlanma süresi birkaç kez sarkmıştır. Bu bağlamda, ilk etapta 2014-15 sezonunda hazır hâle geleceği açıklanan stadyumun açılışı önce 2015-16, daha sonra 2016-17 sezonu başına ertelense de bu hedefler de yakalanamamıştır.",
