Jesse Powell

Jesse Powell is an American entrepreneur who co-founded the cryptocurrency exchange Kraken in 2011 and ran it as chief executive for more than a decade. He built it in direct response to watching Mt. Gox fail from the inside, and the resulting obsession with solvency and security produced the industry's first proof-of-reserves audit, eight years before the rest of the market decided it needed one.

"Don't trust, verify." - a Bitcoin maxim Powell applied to exchanges themselves

Mt. Gox Is the Reason Kraken Exists

Powell's route into crypto was not a whitepaper. It was a disaster.

He had been running an online gaming business and became an early Bitcoin user not long after Satoshi Nakamoto released it. When Mt. Gox, then handling the overwhelming majority of global Bitcoin trading, was hacked in June 2011. Powell went to Tokyo to help. He advised the exchange during the incident and saw at first hand how thin the operational substance behind it was: inadequate accounting, no meaningful segregation of client funds, and no way for anyone outside to verify whether the assets existed.

He concluded that the exchange layer, not the protocol, was the weak point, and that somebody should build one that could survive. Kraken launched trading in 2013. Mt. Gox collapsed in 2014, taking roughly 850,000 BTC with it, and Kraken was appointed to help process creditor claims in the bankruptcy, which is an unusually direct vindication of a founding thesis.

The lesson generalises beyond one exchange. Every subsequent custodial failure has followed the same pattern, which is why understanding crypto exchanges as businesses rather than as websites is the single most useful thing a newcomer can do.

Proof of Reserves, Eight Years Early

In 2014 Kraken commissioned an independent proof-of-reserves audit. Very few people cared at the time.

The mechanism lets an exchange prove cryptographically that it holds the assets it owes, with each customer able to verify their own balance is included in the total without seeing anyone else's. It converts a solvency claim from a marketing statement into something a user can check. Powell argued for years that this should be table stakes and that any exchange refusing to do it was telling you something.

In November 2022 FTX collapsed with an eight-billion-dollar hole and the argument was settled overnight. Proof of reserves went from a Kraken eccentricity to an expectation, and most large exchanges now publish some version of it. Powell had been right for close to a decade, which is a rarer thing in this industry than being right at the right moment.

A Decade of Regulatory Attrition

Kraken's history with US regulators has been long and largely adversarial, and Powell was its most outspoken voice.

In February 2023 Kraken settled an SEC action over its US staking-as-a-service programme, agreeing to shut the service for US clients and pay a penalty. Later in 2023 the SEC filed a separate civil complaint alleging Kraken operated as an unregistered exchange, broker, dealer and clearing agency. Powell was consistently and publicly critical of the agency's approach, at one point describing the SEC as the country's leading obstacle to technological progress, and argued that enforcement without rulemaking left honest operators guessing.

His position, whatever one makes of the tone, was reasonably consistent: he wanted written rules he could comply with, and objected to having compliance defined retroactively through litigation. Competitors including Coinbase under Brian Armstrong made a similar case with more diplomacy and comparable results.

The Culture Fight and the Step Back

In 2022 Powell published an internal document setting out a "crypto-first" culture with a deliberately high bar for mission alignment and a permissive stance on internal debate. It leaked, and the coverage was hostile. Critics said the tone risked alienating staff; Powell offered generous exit packages to employees who disagreed with the direction and framed the whole exercise as protecting focus.

In September 2022 he announced he would step down as chief executive. Dave Ripley took over, and Powell moved to chairman, remaining on the board. He described the change as wanting to spend his time on product and advocacy rather than management, and the timing, in the middle of a bear market and an intensifying regulatory fight, invited less charitable readings.

The Investigation, and How It Ended

In 2023 the FBI opened an investigation into Powell following allegations from the Verge Center for the Arts, a Sacramento nonprofit he had been involved with, which claimed he had unlawfully accessed its computer systems and blocked members' access to email. Agents searched his home and seized devices. Coverage at the time was extensive.

It ended without charges. In April 2025 Powell's attorney was informed the investigation had concluded, and a letter from the US Attorney's Office in June 2025 confirmed his seized devices would be returned. Court filings and his attorney's statements indicated the inquiry concerned only his relationship with the nonprofit and was never connected to Kraken or its customers. Powell has since filed a civil suit against members of the Verge Center board, alleging false statements prompted the federal investigation.

Both halves of that sequence belong on the record. A two-year federal investigation of a major exchange founder is significant, and so is the fact that it produced no charges.

Kraken's Listing Window

With the SEC matter resolved and the DOJ investigation closed, Kraken has been reported to be exploring a public listing, with coverage pointing to a window around the first quarter of 2026. Powell enters that process with no active US enforcement or criminal matter attached to his name, which would not have been true at any point in the preceding three years.

A listing would subject Kraken to exactly the disclosure regime Powell spent years arguing regulators should have written in advance. It would also make the exchange's own solvency a matter of audited public record rather than voluntary attestation, which is a reasonable endpoint for the person who introduced proof of reserves.

What Powell Got Right

Powell's record is unusual in that his central technical conviction was correct and unfashionable for most of a decade. He held that exchanges are the dangerous layer, that solvency should be verifiable rather than asserted, and that customers should be able to check rather than trust. Mt. Gox, Celsius and FTX each proved the point at enormous cost to people who had no way to look.

He is a less persuasive figure on governance and tone, where his instinct for public confrontation created problems that more measured peers avoided. And the deeper implication of his own argument cuts against his business: if exchanges are the weak point, the safest place for assets you are not actively trading is not an exchange at all. Anyone persuaded by Powell's case for verification should decide deliberately between trading and holding, follow the argument through to how to store crypto in self-custody, and treat platform-level assurances as a floor rather than a guarantee against crypto scams and operator failure alike.

Kraken's survival from 2011 to 2026, through every cycle that removed its contemporaries, is the strongest evidence for how he built it. The exchanges that did not survive were not short of users or funding. They were short of the thing Powell insisted on from the start: a way for anyone on the outside to check that the money was actually there.
