Muddy Waters Research

What Muddy Waters Research does

Muddy Waters Research is a privately held investment research firm founded by Carson Block in 2010 and domiciled in the United States as Muddy Waters, LLC. The firm publishes due diligence-based short-seller research reports on publicly traded companies it suspects of fraud, financial misstatement, regulatory violations, or misleading disclosure. Its work began with Chinese-listed equities (most notably the 2011 Sino-Forest report, which preceded the company's bankruptcy and a subsequent Ontario Securities Commission ruling of investor fraud) and has since expanded to U.S.-listed targets across fintech, ad-tech, gaming data, aviation, and healthcare.

The firm's core product is its research reports, distributed on a subscription basis through muddywatersresearch.com. Its underlying investigative methodology combines on-the-ground field work, undercover operations (e.g., investigators posing as sportsbook operators at the ICE 2026 conference to test Sportradar's jurisdictional compliance), proprietary code analysis conducted with cybersecurity experts, and forensic financial accounting. The firm has codified this tradecraft into frameworks such as the "Six Rules of China Due Diligence." Founder Carson Block maintains a high media profile on Bloomberg, CNBC, and at investor conferences (Sohn, Kase Learning, Bloomberg Hedge Funds Summit), which functions as the primary top-of-funnel distribution channel.

Muddy Waters operates with a deliberately small team of 1-10 employees and generates revenue through paid subscriptions to its research, serving institutional investors (hedge funds, asset managers) as its primary customer segment and individual investors as a secondary segment. The firm is independently owned and has no disclosed external funding, parent company, or M&A activity.

Emerging players

• Bonitas Research: Bonitas Research publishes short-seller research with a forensic-accounting focus on North American listed companies. Comparable to Muddy Waters in publishing paid, evidence-led research alleging misconduct at public companies.
• Iceberg Research: Iceberg Research is a Europe-based short-seller research firm that publishes investigative reports on publicly traded companies it suspects of fraud or mismanagement. It is comparable as an emerging player in the same short-research subscription niche but with a European footprint.
• Wolfpack Research: Wolfpack Research is a newer entrant in the short-research space, founded by former Muddy Waters analyst Jed Silver, which directly leverages the investigative short-seller playbook. Its existence as a credible new entrant validates the demand for Muddy Waters' type of research.
• Fuzzy Panda Research: Fuzzy Panda Research is a newer short-seller research firm publishing investigative short reports on public companies. It competes in the same paid investigative-research subscription niche as Muddy Waters, with overlapping target sectors such as Chinese ADRs.

Direct peers

• Blue Orca Capital: Blue Orca, founded by Soren Aandahl (formerly of Glaucus Research), publishes short-seller research reports on listed companies, particularly those with operations in China. The firm shares Muddy Waters' investigative style and focus on cross-border due diligence.
• Citron Research: Andrew Left's Citron Research is a long-running short-selling research firm that publishes paid research notes on public companies it believes are overvalued or fraudulent. Citron is the closest historical analogue to Muddy Waters in combining a single high-profile founder with subscription-based short research.
• Spruce Point Capital Management: Spruce Point is an activist short-focused research firm that publishes due-diligence-driven reports alleging fraud or accounting irregularities at public companies. The model — single high-profile firm publishing paid short research — closely mirrors Muddy Waters' subscription research approach.
• Hindenburg Research: Founded by Nathan Anderson in 2020, Hindenburg is the most direct competitor to Muddy Waters, publishing investigative short-seller reports on public companies using similar on-the-ground, forensic-accounting-led methodologies. Both firms operate small teams and distribute paid research via subscription to institutional short-oriented investors.
• Kerrisdale Capital: Kerrisdale Capital runs a long/short equity strategy and publishes publicly available short theses with detailed investigative research. It overlaps with Muddy Waters in publishing rigorous, public short-investment research, though it operates alongside a fund management business.

Broad incumbents

• Bloomberg Intelligence: Bloomberg Intelligence is the broad incumbent in equity and industry research, providing institutional research, data, and analytics on thousands of public companies. While not a short-seller specialist, it is the broader incumbent research platform through which many of the same institutional investors (Muddy Waters' customers) consume investment research.
