In a bizarre and unexpected twist that has sent shockwaves through both the tech and sports worlds, Tesla CEO Elon Musk has allegedly sent a 5-word warning to Türkiye after rising football star Arda Güler publicly declined a multi-million-dollar advertising partnership with the electric car giant.

According to early reports from sources close to the situation, Güler — the 19-year-old sensation currently playing for Real Madrid and widely regarded as the future face of Turkish football — rejected a high-profile endorsement deal with Tesla, citing personal values and a preference to stay focused on his career. The decision, made during a press briefing, was met with admiration from fans but reportedly left Musk furious behind the scenes.

Shortly afterward, Musk allegedly sent a cryptic and direct message aimed at both Güler and the Turkish market:

“He will regret this decision.”

Those five words have sparked international controversy, igniting debates about corporate pressure, athlete independence, and the influence of billionaires in the world of sports.

While no official statement has come from Musk or Tesla, insiders claim that the tech mogul was counting on Güler’s rising star and global appeal to push Tesla’s expansion strategy in Turkey and across Europe. The sudden rejection — made very public by Güler’s camp — was seen as both a personal and professional blow to Musk.

The Turkish Football Federation has declined to comment, but fans and media across the country have come to Güler’s defense, with hashtags like #StandWithArda, #TeslaBackOff, and #TürkiyeSupportsGüler now trending on social media.

In Madrid, Güler has remained quiet since the controversy began but is reportedly “calm and focused” ahead of his next international match.
