Brett Harrison — FTX US former president speaks out

Professional Background & Market Philosophy

• Brad Harrison served as Head of ETF Technology at Citadel, President of FTX US, and is now the founder of Architect.
• Harrison views the growth of passive investing (ETFs) as net positive for individual investors due to lower costs and diversification.
• He identifies a specific downside of passive investing: it creates artificial correlation between instruments (e.g., Tesla moving with the S&P 500) purely based on index inclusion rather than fundamental value.
• Harrison argues that high-frequency trading (HFT) optimizations, even at the nanosecond level, provide societal value by ensuring liquid, efficient markets and minimizing the gap between news events and price discovery.
• He counters the "zero-sum" critique of HFT by noting that the resources spent on latency improvements are subsidized by value creation (profits) and may generate spillover infrastructure benefits (e.g., microwave networks).
• Harrison contrasts the "trader mentality" regarding tail risk (calculating probabilities of rare events) with civilizational risks, arguing that while it helps estimate probabilities, it does not offer actionable solutions for non-financial disasters.
• He notes that HFT firms adapted well to the COVID-19 pandemic, maintaining profitability through remote work, challenging the notion that physical co-location is strictly necessary for trading success.

FTX Tenure: Leadership & Organizational Culture

• Harrison joined FTX in March 2021 as President of FTX US, a role he accepted despite a desire to avoid proprietary trading, based on Sam Bankman-Fried's (SBF) assurance that Alameda Research and FTX were walled off.
• Harrison observed that SBF spent "virtually no time" helping the company move forward operationally, focusing instead on image, brand, and PR activities.
• A key structural disagreement involved the engineering team; Harrison advocated for hiring more developers to build a sustainable US infrastructure, while SBF insisted on keeping the core codebase small (approx. two developers) and centralized in the Bahamas.
• Harrison describes SBF's management style as "conflict-avoidant," noting he would often blow off employee concerns, avoid direct conversations, and refuse to delegate authority to US-based C-level staff.
• Harrison's relationship with SBF deteriorated after he sent a letter demanding better communication, the establishment of a separate US management team, and the growth of the US development team.
• In response to Harrison's letter, SBF reportedly threatened Harrison with termination and stated SBF would "destroy your professional reputation."
• SBF subsequently threatened Harrison's career, asking him to write an apology letter to remain employed, which Harrison refused, leading to his resignation in late September 2022.
• Following the resignation, SBF announced the closure of the Chicago and San Francisco offices, effectively forcing employees to relocate to Miami or leave the company.
• Harrison claims SBF publicly misrepresented his departure to investors and media, stating Harrison was fired for refusing to move his family to Miami, which Harrison confirmed was false.

Red Flags & The Collapse

• Harrison identified a significant red flag regarding Alameda Research: the delayed payment of semester bonuses (due in June and December) by 2-3 months in 2021-2022, which caused employee panic regarding liquidity.
• He notes that SBF maintained a "cult-like" belief in the small development team and kept financial details, including massive real estate purchases and venture deals, strictly within an inner circle to avoid internal criticism.
• Harrison states he had no access to FTX's core bank accounts or the financials of the Bahamas-based entities, relying on public volume data and internal reports that appeared consistent.
• He asserts that at the time of his departure, FTX US appeared solvent, with separate custody of assets (AWS, bank accounts, wallets) and a clear operational separation from FTX International, despite shared governance (SBF as CEO of both).
• Harrison reveals that during the FTX collapse, the "conventional narrative" regarding the sequence of events (Binance deal failure, FTT dump, Alameda insolvency) was largely accurate, thanks to rapid legal investigations.
• He observes that SBF's mental and physical state deteriorated significantly from his early days at Jane Street (where they first met), becoming angry, anxious, and unable to sleep.
• Harrison argues that the concentration of power in SBF, Nishad, and Gary, combined with the lack of an independent board, made it impossible for employees to detect fraud without disbelieving audited financials and regulatory assurances.
• He notes that the "FTX mafia" may not emerge as a positive force like PayPal alumni, as the talent is now exiting a failed company in a crisis rather than a successful acquisition.

Architect & The Future of Crypto Infrastructure

• Harrison founded Architect to provide a unified infrastructure layer allowing traders to access centralized exchanges, DeFi protocols, and custodians without building custom integrations for each.
• The company aims to solve the "market fragmentation" problem where individual exchanges have no incentive to build cross-exchange connectivity software.
• Architect's design philosophy prioritizes security, ensuring users can connect various wallets and exchanges without ever handing over private credentials to Architect.
• Harrison estimates that the crypto market will likely remain a mix of CeFi, DeFi, and regulated entities, but Architect intends to facilitate liquidity across all three regardless of where the market settles.
• He highlights that many centralized exchanges suffer from poor API designs (e.g., order cancellation issues) compared to traditional finance, creating friction for institutional traders.
• Harrison expects the "FTX stigma" to be the primary hurdle in hiring and fundraising, noting that the current market oversupply of talent (due to layoffs) has ironically made recruiting easier for him.
• He maintains that crypto is a viable $1-3 trillion asset class that requires mature infrastructure, similar to traditional commodities like gold or oil, to function efficiently.
• Harrison anticipates that blockchain technology could eventually replace current slow, error-prone equity settlement systems (currently 2-day cycles) with faster, transparent on-chain settlement layers.
• He argues that crypto markets are not yet as efficient as equity markets, leaving opportunities for sophisticated individual traders to generate alpha.
