Jeffrey Randall Allen looked at a phone in the middle of an extremely difficult challenge during MrBeast’s Beast Games late at night. Instead of asking for money or anything he might gain an upper hand from, Jeffrey Randall Allen surprisingly Direct Messaged Elon Musk.
Allen, known as Player 831, walked away with the $10 million grand prize the biggest in game show history on Amazon Prime Video’s high-stakes reality competition. But his real mission wasn’t the money. It was his young son Lucas, who lives with Creatine Transporter Deficiency, or CTD.
During one of the intense “cube” challenges, contestants got access to a phone and could “ask for anything.” Allen didn’t hesitate. He reached out directly to Musk, hoping for a call about potential help for Lucas’s rare genetic disorder.
“I asked for a phone call with Elon Musk because I was trying to go between Tesla, which is an energy company, and Neuralink, the brain, can he figure out how to get creatine to the brain?”
Allen said in an interview. He added that Musk replied the next day, but it was too late at night during the show for an immediate conversation.
Allen has been open about the emotional weight. In the full YouTube interview with Jon Youshaei titled “I Prayed for a Miracle. Then MrBeast Called,” he explained the moment around the 53:49 timestamp. He said he was so focused on his son that he might have walked away from the competition entirely if it meant getting Musk on the line right then he even mentioned he could have gotten “cuffed” (eliminated) because family came first.
CTD is a rare X-linked genetic disorder caused by mutations in the SLC6A8 gene. It stops creatine an essential energy molecule from properly reaching the brain and muscles. This results in developmental disorders, speech problems, intellectual disabilities, movement problems, and even seizures. Lucas has been diagnosed since about 2019, when his parents realized that he had not met certain milestones by the age of eight months. At the moment, there is neither cure nor any FDA approved treatment.
Allen has always stated that he participated in Beast Games with the sole aim of raising awareness for the research of CTD, and not for any monetary benefit.
“It was not a money issue,”
He insisted in the interview.
MrBeast (Jimmy Donaldson) has built a massive U.S. following through over-the-top challenges and philanthropy. His Beast Games turned that formula into a global streaming hit on Prime Video, blending intense competition with raw personal stories. Allen’s win and his outreach to Musk tapped into two big American fascinations: viral entertainment and the idea that tech billionaires might solve tough problems.
The clip of Allen’s plea spread quickly on platforms like X and Instagram, where he continues posting updates, including one titled
“I Tried Calling Elon Musk Again…”
Musk’s companies, especially Neuralink (focused on brain interfaces), made the request feel like a long-shot hope for neurological breakthroughs, even if no direct collaboration has been confirmed.
Allen, who serves as Vice Chair and Director of Impact for the Association for Creatine Deficiencies (ACD), has directed much of the prize money toward research. He pledged $1 million over two years to ACD’s “Race for a Cure” and has raised hundreds of thousands more through events like Ruck4Rare walking marathons with a weighted backpack to symbolize the daily burden kids with CTD carry. His family’s total contributions are approaching $1.5 million in recent reports.
He has also rung the Nasdaq Closing Bell and appeared in segments highlighting CTD. Lucas, described as a bright and resilient boy, has a younger brother Jack, and the family stays active in advocacy via creatineinfo.org/lucas.
Allen’s story puts a spotlight on rare disease challenges in the U.S., where conditions like CTD often struggle for funding and awareness. Research partners include institutions like UCLA and Stanford, with work ongoing into gene therapy and better delivery methods for creatine to the brain.
