Millionaire Biohacker’s Nighttime Erections Fuel Rising Prediction Market Bet

There’s a new Polymarket bet for how long Bryan Johnson’s penis stays erect during nighttime. The antics of a man who injected his teenage son’s blood into his veins and underwent “penis rejuvenation therapy” has been a persistent topic on the prediction market—or more precisely, his penis has.

“This market will resolve to ‘Yes’ if Bryan Johnson sustains a nighttime erection for 2 hours and 12 minutes or more based upon the highest of three readings taken during the last week of December 2024,” the market’s official description reads.

Currently, there’s a bit over $22,000 at stake. We’ll know who wins by January 15, 2025, 12:00 PM ET.

Johnson, the 45-year-old tech millionaire who spent over $4 million testing anti-aging treatments on himself, is all in on the stunt, and announced that Polymarket had opened betting on his nighttime tumescence.

A nighttime erection “is something you can’t really try your best at,” Johnson posted on X (formerly known as Twitter). “They just happen or they don’t. You go to sleep and the body does its thing.”

The market will resolve based on measurements taken during the last week of December 2024, with a 50-50 split if Johnson doesn’t release data by January 15, 2025.

This unusual betting market follows Johnson’s previous weenie-related wagering history. Earlier this year, bettors who backed his ability to achieve specific sperm count targets above 20 million per ejaculation walked away with 50-50 result against skeptics after a disputed bet.

The stakes are higher this time, and Johnson warned bettors that his current travel schedule could impact the rigidity of his schmeckel.

“I return from China on the 16th of [December] and measurement will take place during the final week of the month,” he noted, explaining that international travel disrupts his body’s rhythms. “It’s TBD how long it takes my body to adjust normal NTE.”

Yeah, that’s how he abbreviates “nighttime erections.”

“NTE is a significant biological age marker representing sexual, cardiovascular, and psychological health,” Johnson posted, citing research showing deficient nocturnal erections correlate with a higher risk of premature death.

“Men: If you’re not having robust boners at night, you’re 70% more likely to die prematurely” he wrote in a recent blog post. “If you’re grinding at the expense of your health, you’re flaccid.”

At the risk of telling you more about the man’s putz than anyone would really want to know, consider that Johnson’s best recorded performance to date reached 2 hours and 59 minutes—a feat he claims matches an average 18-year-old.

That said, he had help via a combination of focused shockwave therapy and Botox treatments—which, to be fair, sounds like cheating. However, the aptly named Johnson notes these effects fade over time, adding another variable for potential bettors to consider.

These experiments form part of Johnson’s larger “Project Blueprint,” a comprehensive, open-source, anti-aging protocol that includes over 100 daily supplements, strict sleep monitoring, and constant blood testing. The program, which consumes $2 million annually, has reportedly reduced his biological age to that of a 30-year-old across various metrics.

Johnson’s methods have proven effective enough to attract Netflix’s attention. The streaming giant plans to release “Don’t Die,” a documentary following his quest for immortality, next year. Despite his extreme approach, Johnson’s basic health advice remains surprisingly simple.

Want more? OK. Johnson’s round of penis treatments began in mid-August with three sessions of shockwave therapy. “Improvements can take up to 12 weeks after the therapy,” Johnson noted, another important factor bettors ought to consider.

Bettors appear to be pretty confident that Johnson will successfully deliver. Some 67% of wagers trust that Johnson’s johnson will stand up to the challenge.
