Kalshi Leads NFL Betting App Downloads for a Fourth Straight Week
Kalshi topped US and Canada real-money gaming app downloads for the fourth consecutive week of the NFL season, according to Sensor Tower data cited by Citizens JMP Securities and reported by Legal Sports Report on October 7. The prediction-market platform accounted for 32% of Week 4 downloads among gaming apps, well ahead of DraftKings in second at 12%, Polymarket at 11%, and FanDuel at 8%.
Downloads are rising, but not evenly
Total real-money gaming app downloads across the US and Canada climbed 24% year over year in Week 4 and are up 22% through the season's first four weeks overall. But that growth isn't spread evenly across the industry: established sportsbook and fantasy-sports operators largely posted year-over-year download declines even as the category as a whole grew by double digits. Analysts attributed part of the gap to prediction-market apps simply having a much larger pool of potential first-time downloaders to draw from, compared with sportsbook apps that are already installed on many bettors' phones in legal states.
Prediction-market volume hits a record
Separately, research from Citizens and Aldrin Research found prediction markets generated a record $89 billion in notional trading volume over the trailing 30 days — a figure the report cautions isn't directly comparable to sportsbook handle, since it measures the value of contracts traded rather than money wagered. Within sports-specific contracts, Kalshi held 55.2% of notional volume over the past 30 days, down from 61.3% in August, while Polymarket held 28.3%. DraftKings' own prediction-market arm, DKeX, grew its share of sports volume from just 0.3% in August to 3.1% — a small slice, but a notable jump for a licensed sportsbook operator's newer entry into the space. On parlay-style combination contracts specifically, Kalshi's share was even larger, at 82.9% of notional volume, with Polymarket second at 9.7% and DKeX at 3%.
Why it matters
The download and volume data underline how much ground prediction-market platforms have gained inside the traditional NFL betting calendar, even as their legal status continues to be fought over state by state — Kalshi and Polymarket currently operate under federal commodities-exchange rules rather than state sportsbook licenses, a distinction at the center of ongoing litigation covered elsewhere on this site. For bettors, the practical takeaway is that the competitive landscape for NFL action now includes a fast-growing category of apps with a meaningfully different regulatory structure than a licensed sportsbook, which is worth understanding before moving money onto any new platform.
