A wild claim made by a Kenyan man Nyakundi Kibiru alleging to be the eldest son of billionaire Elon Musk took social media by storm this week.

What began as a bizarre but headline-grabbing claim quickly fell apart under scrutiny, after the  40-year-old mental health activist declared himself to be the eldest son of tech billionaire Elon Musk only to have the internet swiftly dismantle his story.

Kibiru’s viral social media posts, in which he demanded a DNA test from Musk and cited a supposed romantic encounter between his mother and the entrepreneur in Kenya’s Masai Mara during the “early 1990s,” drew widespread attention and skepticism in equal measure.

But within hours, online sleuths and fact-checkers began highlighting major inconsistencies — not least of which was the math.

According to Kibiru, he is 40 years old, placing his birth sometime in 1985. Yet, in his story, the alleged relationship between Musk and his mother happened in the early 1990s — which would have made Elon Musk still a teenager at the time and years too late to be Kibiru’s father.

“Musk was born in 1971. If Nyakundi was born in 1985, Musk would have been only 14 — and still living in South Africa — when the child was conceived,” one user wrote in a viral thread that picked the story apart point by point.

Others were even more blunt, with posts reading, “Bro, your math is AI-generated too,” and “Elon Musk didn’t time-travel, man.”

Adding to the implausibility, the photo Kibiru posted to “prove” his resemblance to Musk was quickly flagged by digital forensics experts as being likely AI-generated. Users noted distorted facial features, inconsistent lighting, and smoothing typical of AI tools like Midjourney or DALL·E.

Reverse image searches failed to match the photo to any known individuals, and metadata revealed signs of digital manipulation.

“This is textbook AI fabrication,” said Njeri Gathoni, a Nairobi-based tech journalist. “We’re entering an era where people can spin entire false identities — and for a few hours, they can be believed.”

Elon Musk has not responded to the claim, which isn’t surprising given the volume of strange and speculative allegations frequently directed at him. The billionaire, who has several publicly acknowledged children, has not been linked to Kenya or the Masai Mara in any official record.

Meanwhile, the internet has moved from brief curiosity to mockery. Satirical posts flooded platforms:

Others have used the incident to highlight how AI and misinformation are reshaping public narratives — and not always for the better.

While Kibiru has not responded to the debunking, many observers suggest the episode underscores growing concerns about how AI-generated content, emotional storytelling, and viral algorithms can create a short-lived but potent illusion of truth.

“This situation may have been quickly unraveled, but in the wrong hands, these tools could do real damage,” said Dr. Wycliffe Mutiso, an expert in digital ethics. “We should treat this as a warning, not just a joke.”
