A famous 10-foot CIA sculpture just changed hands, and the crypto firm that bought its last secret says it hasn't peeked, because the mystery of Kryptos is still the point

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.

It was nearly all gone with one wild swing
Two weeks before the auction deadline, two researchers, Jarett Kobek and Richard Byrne, contacted Sanborn to say they’d already found the text of K4. The Smithsonian holds Kryptos-related materials in its archives, and Byrne went to photograph the holdings. Kobek found that Sanborn had inadvertently included K4 plaintext in his own papers.

The researchers agreed not to publish their solution, and the auction went off as planned. According to Scientific American’s report on the Kryptos K4 solution, Sanborn verified the solution's authenticity and asked the Smithsonian to seal the files for the next 50 years, which they did.

Enter Paradigm
The winner was crypto-focused venture capital firm Paradigm, co-founded by a Coinbase co-founder. According to Paradigm's team page for Dan Robinson, Robinson is a General Partner at the firm, where he focuses on crypto investments and research into open-source protocols.

One of the people behind the deal has been into this stuff since he was a kid. Robinson, who joined Paradigm in 2019, has been obsessed with cryptography as a kid. Last summer, he read about the auction and encouraged Paradigm to get involved because it aligned with a lot of the firm's philosophy about the kinds of things it likes to support in the world. Owning a piece of Kryptos could also draw top talent to the firm, which feels very on-brand for the current tech and crypto job market, according to Robinson.

So how do you actually submit a guess
This is the clever bit. The real answer was hashed to create a unique ID. The same function is used for new submissions, and if the two hashes match, the puzzle is solved, all without having to read through every wrong guess manually.

According to Wired, Paradigm will charge $1 per submission, down from the $50 Sanborn charged, in an effort to encourage guesses and discourage brute-force attempts. The firm will also run contests with progressively harder decoding challenges, with the first person to crack each one getting $1,000.

There is no money prize for solving K4 itself. It’s glory and a video Sanborn recorded, just for whoever finally cracks it.

There's still a K5-shaped mystery left
K4 falls, but that’s not the end of the story. Sanborn says that once K4 is solved, K5 will somehow become solvable too. When the time is right, Paradigm will publish the encrypted K5 text and invite the public to have a go at it, Robinson says.

Sanborn doesn't seem quite ready to give up either. He says he will continue to tell people who contact him directly to contact Paradigm instead, but admits he won't shut down his email and people may want him to look at their guesses anyway.

He’s even talked about burying a K5 teaser in future public art. Sanborn has mentioned the concept of embedding K5 in one of his “projection cylinder” pieces, where he projects long strings of scrambled text onto large surfaces, basically hiding a clue in plain sight for anyone who is paying close attention.

Why this matters beyond the crypto world

This is not just a quirky collectibles story. It’s a snapshot of how crypto wealth is increasingly finding its way into cultural history, much the same way tech money has bought sports teams and art collections. It’s also fitting for American audiences that a puzzle that has sat outside the CIA for 35 years now is being defended by a venture firm built on decentralization and open systems. The mystery isn't solved yet, but for the first time in decades it feels like it might actually be within reach.
