Flutter Short Interest Hits Year High Before Tuesday's Print

Flutter Entertainment, the parent company of FanDuel and one of the world's largest online betting operators, reports third-quarter results on Tuesday, November 4, against a backdrop of sharply rising short interest and a notable shift in the ownership register.

Short sellers have added to their positions at the fastest pace in over a year. Short interest has climbed 53% over the past month to reach 9.1% of the free float, the highest level in the data. The move accelerated last week, with shorts rising a further 4.5% in five sessions. Despite that accumulation, borrow conditions remain comfortable: availability is at 685%, meaning there are roughly seven shares available to borrow for every one already shorted, and the cost to borrow is just 0.56%, even after rising 20% over the past week. The lending market is not under stress. Options traders are leaning defensive, with the put/call ratio at 1.65, above its 20-day average of 1.40, though well within the past year's range.

The debate heading into the print centres on the tension between Flutter's structural market-share gains and the regulatory and competitive costs of sustaining them. The company's own FanDuel brand has continued to outpace DraftKings on active users through the NFL season, and the Q2 2026 results beat on both revenue and EBITDA. Brazil's regulatory crackdown, however, removes an estimated $70 million in annual revenue, and promotional spending in the US market remains elevated. At 12.7 times trailing earnings and 8.5 times EV/EBITDA, the stock is not priced for disappointment, and EPS momentum scores rank in only the 11th to 22nd percentile versus peers, suggesting the Street has been trimming expectations rather than raising them.

The ownership picture adds another layer of complexity. Kenneth Dart holds 18.6% of shares, an unusually large single-investor concentration disclosed in a February 2026 13G/A filing. Parvus Asset Management built its stake from 6.7% to 8.8%, as last disclosed in August, making it the second-largest external holder. Canadian Imperial Bank of Commerce filed its first Schedule 13G in August disclosing a 7.3% stake. Running the other way, The Vanguard Group disclosed in March that it had exited entirely after previously holding over 10%, and Capital Research Global Investors trimmed from 5.4% to 3.7%. All stakes are as last disclosed and may have changed since filing. ORTEX puts the chance at 65% that FLUT is added to the MSCI World Small and MSCI USA Small indices at the November Quarterly Review, with an announcement expected November 11 and a trade date of November 30. That same review is forecast, also at 65%, to remove FLUT from the MSCI World, MSCI USA and several related large-cap indices. The stock would need to close above $88.32 to change that call, roughly 7% above its current level of $82.59. The combined selling flow from large-cap deletions is forecast at up to $710 million, against potential buying of $397 million to $707 million from small-cap additions, making the net mechanical impact of the rebalance a live variable alongside the earnings result.

The quarterly print will test whether FanDuel's NFL-season momentum is converting to margin improvement, or whether the combined drag from Brazil, elevated marketing spend and a smaller MSCI universe has begun to reset how the market prices Flutter's long-term earnings power.
