Flutter Entertainment enters September with short sellers quietly rebuilding positions and options markets skewed defensively — even as the borrow market stays comfortably loose.
The most striking development this week is the pace at which short interest has climbed. Shorts rose 21.7% over the past five trading days to reach 7.1% of free float, a level that puts meaningful pressure on a stock already down 5% on the week and 7% over the past month. The rebuild is sharp enough to stand out: short interest was running near 14.4 million shares in early August, collapsed to roughly 10.2 million shares around August 11-14, and has now climbed back to 12.5 million — a partial reversal that suggests fresh bearish conviction rather than a simple covering overhang washing out.
The borrow market tells a different story, and that contrast matters. Despite the short interest rebuild, availability remains well above 700% — meaning there are roughly seven shares available to lend for every one already borrowed. That is loose by any measure. Cost to borrow has actually eased, down 7% on the week to just 0.48%, well below the 0.69% level seen at the start of August. Shorts are rebuilding positions without facing any meaningful squeeze pressure in the lending market. Options positioning amplifies the cautious tone without screaming panic: the put/call ratio runs at 1.58, modestly above its 20-day average of 1.46, and has been elevated all week following a sharp jump from the mid-1.3x range seen in mid-August. That is not an extreme reading — the 52-week high hit 2.10 in early August — but it confirms that options traders are paying more for downside protection than they were two weeks ago.
The Street's fundamental picture offers bears a clearer case than bulls. A recent note in Flutter's coverage flagged a 6% revenue decline and a 70% AEBITDA drop for 2025, with analysts cutting price targets into the $113 range from the prior $132. EPS momentum is deeply negative — ranking in just the 8th percentile on a 30-day basis and the 20th percentile over 90 days — and EPS surprise sits at only the 3rd percentile, meaning Flutter has been consistently missing expectations. The PE multiple has compressed to 14.2x, down 1.25 turns over the past week alone, with price-to-book also falling. The bull case rests on scale: 15.9 million monthly users, a dominant FanDuel position in the US, and forward EPS growth that carries a 60th-percentile ranking on a 12-month basis. The ORTEX short score has crept up to 52.3 from 47.8 two weeks ago, reflecting the recent positioning shift, though it remains in neutral territory rather than signalling an extreme.
Institutional ownership adds a layer of complexity. The ownership register is concentrated, with Kenneth Dart holding 18.6% as last disclosed in a February 2026 13G/A filing. Parvus Asset Management built its stake to 8.8% as of an August 14 filing, up from 6.7% previously — a meaningful addition from an active manager. Canadian Imperial Bank of Commerce filed a fresh 13G in August disclosing a 7.3% position. Meanwhile, Capital Research Global Investors trimmed below 5% in its August 13 filing, and Caledonia (Private) Investments similarly dropped below 5% in August 14 paperwork — both moving in the opposite direction to Parvus. As always, these positions are as-last-disclosed around the 5% threshold; holders dropping below that level can exit without filing again. The stock's nearest peer, DKNG, fell 9.1% on the week — a steeper drop than Flutter's 5% — suggesting the broader online gaming cohort is under pressure, not just Flutter specifically.
Flutter's next earnings event is scheduled for November 9. The most recent print, in August, produced an 11.4% single-day decline followed by a further 6.6% loss over five days — the key question heading into that date is whether the ongoing short rebuild and cautious options positioning reflect a well-founded view on near-term earnings risk, or whether the Parvus stake-building signals smarter money leaning against the bearish consensus.
