Apple leaker Jon Prosser followed through on his pledge to shave his eyebrows after incorrectly predicting an Apple event on March 23, turning the mishap into a charitable fundraiser for Wigs for Kids.
Jon Prosser's eyebrows are gone. On March 23, 2021, the day came and went without an Apple event—and the serial leaker made good on a promise he'd made weeks earlier on his YouTube show Front Page Tech. He'd sworn, with theatrical certainty, that if Apple didn't hold a product launch that day, he would shave them off on camera. So he did, trimmer in hand, turning a failed prediction into a YouTube spectacle complete with dramatic music, self-deprecating humor, and a charitable angle.
Prosser has built a reputation as one of tech's most entertaining leakers, a personality-driven source with what appears to be genuine access to information flowing out of Cupertino. His track record, according to AppleTrack, stood at 78.2% accuracy before the March 23 miss—a respectable hit rate that gave his predictions real weight among Apple followers. He'd made waves with a string of accurate scoops delivered in his signature style: irreverent, funny, and laced with the kind of insider detail that makes tech journalists envious. During an appearance on the Cult of Mac podcast, he'd recounted stories that suggested he had access to the kind of information most reporters could only dream of. But predictions, even from well-sourced leakers, can fail. And when they do, there's nowhere to hide.
The March 23 prediction had circulated among several prominent leakers, lending it apparent credibility. Some observers later wondered whether Apple itself had deliberately seeded the false date as disinformation, a way to identify which journalists were receiving leaks and from whom. It's the kind of cat-and-mouse game that plays out constantly in the tech industry, where Tim Cook has long prioritized secrecy and Apple has grown increasingly aggressive about plugging leaks. Earlier that month, the company had sued Simon Lancaster, a former materials engineer, alleging he'd leaked details about unreleased hardware, feature changes, and upcoming announcements to a member of the media. The legal pressure was real.
But Prosser's response to his own miss was pure entertainment. The Front Page Tech episode opened with a clip of his earlier vow, his voice solemn and certain: "I am so sure, that if you don't get an event on March 23, I will shave off my eyebrows. I'll do it right here for you, on this show." Then the video cut to the present-day Prosser, visibly resigned. "Oh god, yep," he said. "Today is that day." The episode proceeded with his usual mix of tech news and irreverent commentary, building toward the inevitable climax. Around the ten-minute mark, he fired up the clippers. But he'd added a twist: he was turning the stunt into a fundraiser for Wigs for Kids, a nonprofit that provides hairpieces to young cancer patients. "I'm gonna do it! For the kids! For the kids!" he yelled, before following through with theatrical hesitation and then the actual deed.
The moment became a footnote in Apple history—a reminder that even well-connected leakers can get it wrong, and that the tech industry's obsession with secrecy and advance information creates a strange ecosystem where failed predictions become content opportunities. Prosser's accuracy rating would drop as a result of the miss, a measurable cost to his credibility. But he'd handled it with humor and turned it into something that benefited others, which is perhaps the only way to recover from such a public miscalculation. The question now was whether his eyebrows would grow back in time for the next event. According to Prosser's latest prediction, Apple would unveil new products in April—possibly including iPads and the long-rumored AirTags. Whether he'd learned his lesson about making absolute guarantees remained to be seen.
Notable Quotes
I am so sure, that if you don't get an event on March 23, I will shave off my eyebrows. I'll do it right here for you, on this show.— Jon Prosser, in an earlier Front Page Tech episode

The Hearth Conversation Another angle on the story
Why would someone make such a specific, public promise about their own face?
Because in the leaker world, credibility is currency. If you're confident in your sources, you bet on yourself. It's theater, but it's also a way of saying: I believe what I'm telling you.
But he was wrong. Doesn't that destroy his reputation?
It damages it, sure. His accuracy rating drops. But he owned it immediately and turned it into something generous. That matters to people who follow him.
Was the March 23 date actually Apple's disinformation, or did he just miss?
Nobody knows for certain. But it's plausible. Apple has every reason to seed false dates to catch leakers. Prosser might have been fed bad information by a source, or the source might have been fed bad information by Apple itself.
So the leaker got played?
Possibly. That's the risk when you're working with sources you can't fully verify. You're only as good as your last prediction.
Why does he keep doing this if the stakes are so high?
Because being first with accurate information is valuable—financially, professionally, and in terms of audience. One miss doesn't erase a 78% track record. And his audience loves him partly because he's willing to be wrong publicly.
