Ben Delo is a British entrepreneur, mathematician and programmer best known for co-founding BitMEX, one of the early major cryptocurrency derivatives exchanges. His background in software engineering and quantitative finance contributed to BitMEX's development of sophisticated crypto derivatives products, and he is widely credited with a major role in the development of the perpetual swap — the funding-rate-based perpetual futures contract that became a defining crypto trading instrument. He is no longer a BitMEX executive. His U.S. legal case ended with a guilty plea in 2022 to a Bank Secrecy Act violation, followed by a presidential pardon in March 2025. In July 2026, BitMEX announced that it would cease operations on September 23, 2026. This profile is current as of August 2026.

1. About Ben Delo
Ben Delo is a British entrepreneur, mathematician and programmer whose relevance to crypto is primarily as a co-founder of BitMEX and a contributor to crypto derivatives infrastructure. His professional path runs from mathematics and computer science at Oxford, through software engineering and quantitative/high-frequency trading, to the founding of BitMEX in 2014, its growth into one of the largest crypto derivatives exchanges, a major U.S. regulatory case, a presidential pardon, and a later shift toward philanthropy and public-interest work. He is no longer an operational BitMEX executive.
2. Education
Reliable public biographies identify Delo as having studied Mathematics and Computer Science at the University of Oxford, receiving high academic honours. This profile does not publish unsupported stories about school or childhood, and does not include health information.
3. Software Engineering Background
Before BitMEX, Delo worked in technology and finance. Public biographies reference software engineering work at IBM and related technology roles. This profile does not attribute specific patents to him without checking original patent records, and does not exaggerate his role at major technology employers.
4. Quantitative Trading Background
Delo's pre-BitMorg career included quantitative and high-frequency trading work. Public biographies reference roles at JPMorgan (Hong Kong) and GSA Capital, involving kdb+/Q and trading-engine development. This quantitative and programming background influenced the later BitMEX trading architecture. This profile does not exaggerate his role at these financial institutions.
5. Founding BitMEX
BitMEX was founded in 2014 by Arthur Hayes, Ben Delo, and Samuel Reed. This founder group is confirmed in current BitMEX historical materials and U.S. Department of Justice records. The exchange was operated by HDR Global Trading Limited and was based in Seychelles. The three co-founders built the early trading engine and derivatives products together; this profile does not attribute the entire exchange solely to one founder.
6. Role at BitMEX
Per U.S. Department of Justice records, Delo served in several executive positions at BitMEX, including Chief Operating Officer (COO), between September 2015 and September 2020. His responsibilities included trading-engine architecture, product design, operations, risk systems and backend market infrastructure. COO is not his current title — he is a former executive of BitMEX.
7. Perpetual Swaps
A perpetual swap (or perpetual futures contract) is a derivative that resembles a futures contract but has no expiry date. Instead, it uses a funding rate mechanism to keep the contract price tethered to the underlying spot price: when the contract trades above spot, longs pay shorts; when it trades below, shorts pay longs. Perpetual swaps support long and short positions with leverage, with liquidation when margin falls below required levels. They became important in crypto because they allowed continuous leveraged exposure without contract rollover.
Regarding Delo's role: in August 2022, Izabella Kaminska at Bloomberg described Delo as “the BitMEX co-founder most responsible for the perpetual swap's invention.” CoinDesk has described BitMEX as “the exchange that invented perps.” This profile uses careful attribution — Delo played a major role in BitMEX's perpetual swap product design and implementation — while acknowledging that the product was the result of the broader BitMEX founding team and that multiple people contributed.
8. Trading Infrastructure
BitMEX's trading infrastructure included a derivatives matching engine, margin and leverage systems, liquidation engines, risk management, an insurance fund, market data feeds and order execution. Delo's software engineering and quantitative-finance background informed his work on these systems. This profile does not describe the architecture as risk-free.
9. Leverage and Risk
BitMEX became known partly for offering highly leveraged cryptocurrency derivatives (up to 100x). Leverage amplifies both gains and losses: leveraged positions can be liquidated when price moves against the trader, and volatility can cause rapid margin calls. High-leverage trading carries substantial risk of total loss, alongside counterparty and exchange risk. This profile does not promote high leverage.
10. Regulatory History
BitMEX's regulatory history is a central part of Delo's profile. U.S. authorities investigated BitMEX for failing to implement adequate anti-money-laundering (AML) and know-your-customer (KYC) programs, as required by the Bank Secrecy Act (BSA). The U.S. Department of Justice and the Commodity Futures Trading Commission (CFTC) brought enforcement actions against BitMEX and its founders.
11. 2022 Guilty Plea & Sentence
On February 24, 2022, the U.S. Attorney for the Southern District of New York announced that Ben Delo and Arthur Hayes had each pleaded guilty to one count of violating the Bank Secrecy Act by “willfully failing to establish, implement, and maintain an anti-money laundering program at BitMEX.” Under their plea agreements, Delo and his co-founders each agreed to pay a $10 million criminal fine. On June 15, 2022, Delo was sentenced to 30 months of probation (through December 15, 2024). This was a Bank Secrecy Act / AML compliance conviction — not a fraud conviction. This profile uses precise legal terminology and does not describe unrelated allegations as proven facts.
12. Presidential Pardon
On March 28, 2025, U.S. President Donald Trump granted pardons to BitMEX co-founders Ben Delo, Arthur Hayes, and Samuel Reed, as well as former employee Gregory Dwyer (confirmed by Reuters, CNBC, and Bloomberg). Delo issued a statement describing the pardon as “a vindication of the position we have always held.” A presidential pardon does not erase the historical fact that the guilty plea and conviction occurred; it is an executive act of clemency, not a judicial exoneration.
13. What Happened to BitMEX?
On July 23, 2026, BitMEX announced that it would shut down operations on September 23, 2026 at 04:00 UTC, following a strategic review of the business and the broader crypto industry by the board of HDR Global Trading Limited. New account registrations were halted immediately. Users were urged to close positions and withdraw funds before the deadline; any open positions remaining at closure would be force-closed. As of August 2026, BitMEX's status is wind-down / scheduled for closure. Status checked: August 2026.
14. BitMEX Historical Significance
BitMEX was one of the most influential early crypto derivatives exchanges. Its perpetual swap product, high-leverage offering and professional trading infrastructure helped shape the crypto-native derivatives market and influenced later centralized exchanges. This profile does not use unsupported claims such as “invented crypto trading” or “world's most important exchange.”
15. What Is Ben Delo Working on Now?
Current Activities: Recent public biographies describe Delo as having shifted much of his attention toward philanthropy and public-interest projects, particularly in mathematics and science.
Previous Crypto Role: Co-Founder and former COO of BitMEX (2014–2020 executive period).
Status Unclear: Any additional current business or advisory roles beyond publicly documented philanthropic activity are not independently verified and are omitted.
Information checked: August 2026
16. Mathematics and Science
Recent public reporting indicates that Delo has directed substantial funding toward mathematical and scientific causes. The Milken Institute describes him as a major donor across mathematics education, neurodiversity, Commonwealth-related initiatives, and organizations supporting rationalism and free inquiry. This profile keeps philanthropic activity factual and does not turn it into promotional praise. Specific donation amounts and recipient institutions are presented only where independently verified.
17. Why Ben Delo Matters in Crypto
His relevance lies at the intersection of BitMEX, crypto derivatives, perpetual swaps, quantitative trading, trading-engine infrastructure and the growth of professional crypto markets. His BitMEX history also includes major regulatory failures (the BSA/AML case) and a later presidential pardon. This profile presents both the technical/business influence and the regulatory history without sanitizing or sensationalizing either side.
