To Zero and Beyond | Building Muddy Waters Capital with Carson Block | Other People's Money with Max Wiethe

Episode Summary

Executive Summary: Carson Block traces how skepticism about fraud in the market led him from long-only investing and law to founding Muddy Waters and pioneering activist short selling. The conversation then shifts to the economics of running a short-activist fund, including capital constraints, fee structure, regulatory burdens, and why Muddy Waters expanded into Vietnam and junior mining to apply its research edge in other underfollowed markets.

Main Topics: From long-side investor to short seller (Priority: 5/5): Block explains his early exposure to investing through his father, his disillusionment with widespread fraud and weak verification in public markets, and how that experience pushed him toward skepticism and eventually short activism. The Orient Paper breakthrough and birth of Muddy Waters (Priority: 5/5): A deep dive into Block's first major fraud report, how it went viral, and how it transformed a one-off project into a business model built on public exposés and trading around them. How activist short selling is monetized (Priority: 5/5): Block details the evolution from self-funded trade publication, to balance-sheet provider arrangements, to launching pooled funds, emphasizing that the business depends on rare, high-conviction opportunities rather than frequent trading. Fund economics, fees, and regulatory friction (Priority: 5/5): The discussion covers Muddy Waters' higher fee structure, the burden of compliance and legal costs, and Block's view that SEC rules and asset thresholds make small fund businesses harder to run and less competitive. Expanding beyond short activism: Vietnam and mining (Priority: 4/5): Block describes using the firm's China-based research and governance expertise to launch a long-only Vietnam fund and a junior mining strategy, arguing that deep research, communication, and skepticism transfer across markets. Allocator behavior and niche LP base (Priority: 4/5): Block explains that investors in activist-short products tend to be smaller family offices, funds of funds, and select endowments, while larger institutions often avoid the reputational risk or do not understand the strategy's edge. Market structure and industry consequences (Priority: 4/5): Block argues that higher compliance costs and regulatory hurdles push talent toward pod shops and large firms, reduce coverage of small-cap/micro-cap markets, and worsen market quality overall.

Key Arguments: Public markets, especially in microcaps and China-linked companies, are rife with misrepresentation, which makes skeptical, forensic research a durable edge. Activist short selling is a capital-constrained business: the model relies on a small number of high-conviction trades and cannot scale like long-only or multi-manager strategies. Publishing fraud research can create trading opportunity, but the real business requires institutional shorting infrastructure and balance-sheet support. High compliance and legal costs are not neutral; they function as a tax that disproportionately harms small managers and reduces market breadth. Muddy Waters can transfer its core competencies—deep diligence, communication, and legal/structural analysis—to other underfollowed markets like Vietnam and junior mining. LPs in short activism often prefer lower-volatility, lower-return profiles and may resist strategies that hold shorts longer, even if that could improve long-term returns. Regulatory and reputational constraints make it difficult to market niche strategies broadly, even when the research process is strong.

Data Points: Orient Paper market cap at publication: $150 million - Block says the first major fraud report targeted a company with this approximate valuation in 2010. Claimed revenue reported by Orient Paper for 2009: $103 million - Block says the real figure was roughly $2.5-$3 million, highlighting the alleged fraud. Balance-sheet provider anchor commitment: $40 million - A family office initially planned to anchor the new fund before the GameStop/Melvin event changed sentiment. Initial pooled-vehicle fee structure: 2.5% management / 30% incentive - Block says Muddy Waters launched its first pooled vehicle with a higher, clean fee structure but later thought pass-throughs should have been used. Break-even period after outside capital: 3-4 years - Block says the management company did not break even quickly and cost structure rose after launching outside capital products. Current short-activist AUM: North of $200 million - Block references the scale of the activist short products in discussing economics and capacity. Typical annual short-activist trade count: 4-5 trades per year - Block says the firm can only produce a small number of high-quality activist shorts annually. Maximum theoretical activist capacity: About 6 trades per year - Block says the firm could perhaps do six if firing on all cylinders, but usually does fewer. Trade count with balance-sheet provider model: 25-30 trades per year - The balance-sheet provider business lets Muddy Waters support more positions across clients and reduce concentration. Initial fund AUM growth limit: About $250 million - Block says the original fund became cumbersome around this size and they did a partial redemption. Vote result for Mayfair Gold board replacement: Over 91% - Block notes a successful activist campaign in junior mining. Investor qualification threshold for short-activist funds: $5 million net worth or more - Block says those vehicles rely on the qualified purchaser exemption. Accredited investor threshold: $1 million net worth or $200,000 annual income - Block contrasts this with newer Vietnam and mining vehicles using the 506C route. SEC registration threshold cited from Dodd-Frank: $150 million AUM - Block argues this threshold has not been indexed and is now much lower in real terms. Equivalency of $150 million in 2011 dollars: Almost $800 million today - Block uses inflation to argue the regulatory threshold is outdated. Regulatory attorney hourly rate in 2012: $1,200/hour - Block cites early big-firm legal costs as a reference point for rising compliance expenses. Regulatory attorney hourly rate today: $2,500/hour - Block says legal/compliance costs have increased sharply. Number of hedge funds referenced in the industry: 33,000 - Block uses this figure while arguing the industry is highly fragmented and burdened by regulation.

Pivotal Quotes: ""I had assumed wrongly as do probably 99 point something percent of investors that auditors are there to perform an anti-fraud function. That's, that is literally not what they do."" — Carson Block: Explaining how frauds in China and the broader market changed his worldview and pushed him toward short activism. ""If your goal in life, or if one of them is to never have a conversation with the SEC, there's probably no reason for us to continue speaking."" — Carson Block: Describing how he filtered out potential capital sources after publishing his first fraud report. ""I think that these are significant issues, especially with the SEC's view of its books and records. You know, it's such an expansive view of what that covers now."" — Carson Block: Critiquing regulatory burden and the way compliance costs affect small managers and market structure.

Implications: The episode shows how niche fund strategies are built on expertise, credibility, and scarce capital, but can be squeezed by regulation and scale limits. For investors, it highlights why activist shorting is hard to replicate—and why firms like Muddy Waters keep broadening into adjacent underfollowed markets.
