For more than three decades, a copper statue outside CIA headquarters at Langley has quietly driven codebreakers up the wall. According to a recent feature in Wired, a crypto-focused venture capital firm has effectively become the official keeper of the last unsolved secret of that sculpture, and the people involved say they haven’t even looked at the answer themselves.
If you’ve ever gone down the rabbit hole of the internet researching unsolved codes, you’ve likely heard of Kryptos. Here's what's going on, and why it's a bigger deal than it sounds.
What even is Kryptos
In 1990, artist Jim Sanborn installed a rippled copper sculpture at CIA headquarters, covered in four panels of coded text. According to the NSA, the sculpture is about 10 feet tall and has four encrypted panels that professional and amateur cryptanalysts have been trying to crack ever since it went up.
Three of them were cracked within about a decade. But the fourth, a tricky 97-character message known as K4, has confounded everyone for decades. Sanborn has been fielding years of wrong guesses and, more recently, a flood of absurd AI-assisted submissions.
The artist finally sold the answer
Sanborn, now 80, decided he'd had enough and finally sold the answer. He also wanted to grow his retirement fund. So in 2025, he arranged the auction of the solution to K4 with an auction house, along with the solution to an unrevealed panel, K5.
The bidding was intense. According to an Associated Press report on the auction of the Kryptos archive, the information required to decipher K4 fetched almost $1 million, with Sanborn receiving $770,000. The names of the winners were kept secret for a time. That has changed recently.
