Key Takeaways
- • Four major hedge funds—AQR Capital Management, DE Shaw & Co, Marshall Wace, and Two Sigma Investments—have disclosed combined short positions totaling approximately £640m (€738m) against Flutter Entertainment, representing 5.15% of the company's 177 million shares at a Thursday price of £71.46.
- • Flutter's share price has collapsed nearly 70% since July 2025, falling from an all-time high of over £230 to £71.50, driven by operational setbacks and strategic challenges that have attracted aggressive short-seller interest.
- • Two Sigma Investments holds the largest disclosed short position at 2.17% of available shares and is leveraging artificial intelligence, machine learning, and data science capabilities to execute its bearish thesis against the Paddy Power owner.
- • Market analysts estimate the true short position may be substantially higher—potentially double the disclosed 5.15% at closer to 10%—as disclosed FCA filings exclude short selling activity on Flutter's concurrent New York listing.
- • The short campaign reflects broader sector weakness, with hedge funds generating over $2.3bn in profits this year betting against gambling stocks amid mounting regulatory and operational pressures.
Summary
Four of the world's largest hedge funds have established a coordinated bearish position against Flutter Entertainment, the Irish gambling giant behind Paddy Power and Betfair, with combined disclosed short positions valued at £640m on the London Stock Exchange. The four funds—AQR Capital Management, DE Shaw & Co, Marshall Wace, and Two Sigma Investments—collectively hold approximately 9 million shares representing 5.15% of Flutter's 177 million outstanding shares, according to FCA filings disclosed as of May 2026.
The aggressive short bet reflects a dramatic deterioration in Flutter's valuation over the preceding eleven months. Since July 2025, when the company's shares traded at an all-time high exceeding £230, the stock has declined approximately 70% to £71.46, erasing roughly £30 billion ($40 billion) from market capitalization. This collapse has been driven by multiple operational setbacks and strategic missteps that have made the company an attractive target for short sellers betting on further downside.
Two Sigma Investments has taken the most pronounced position, disclosing a 2.17% short holding. The quantitatively-driven hedge fund is known for deploying sophisticated artificial intelligence, machine learning, and data science methodologies to inform its trading decisions, suggesting a systematic rather than sentiment-driven thesis against Flutter's prospects. DE Shaw, which commenced its short position in October 2025, has built a 1.49% stake, while Marshall Wace and AQR Capital Management hold additional disclosed positions.
Market analysts caution that the disclosed 5.15% short position likely understates the true bearish exposure. One analyst noted that the FCA filings do not capture short selling activity on Flutter's concurrent New York listing, suggesting that aggregate short interest could realistically reach 10%—nearly double the disclosed level. This interpretation suggests the actual monetary value of the short bet substantially exceeds the £640m figure calculated from London exchange positions alone.
The Flutter short campaign is part of a broader wave of hedge fund profitability from bearish gambling sector bets. Across the gambling industry, hedge funds have generated over $2.3bn in profits during 2026 by shorting listed gaming and sports betting operators facing mounting regulatory headwinds, consumer demand challenges, and operational execution failures. Flutter's combination of household brand recognition and significant valuation destruction has made it a focal point for this sector-wide short strategy.
