Kalshi eats into sportsbook app download share during NFL Playoffs

Summary

US sportsbook apps saw subdued performance during the NFL Divisional Round, with combined legal US and Canadian sportsbook downloads of about 836,000 — a 2% decline year on year. Weekly real‑money gaming downloads have now fallen year on year for roughly 12 consecutive weeks (excluding a couple of market launches).

Major operators were hit unevenly: BetMGM downloads fell ~25% YoY, FanDuel ~14%, Caesars ~8%, while DraftKings eked out ~1% growth. Hard Rock benefited from market expansion (+43% YoY) but couldn’t offset the wider softness.

Against that backdrop Kalshi, the prediction‑market app, surged to roughly one million downloads during the NFL playoffs — its biggest two‑week share ever — and led all apps in absolute download volume. Analysts estimate Kalshi’s expansion has the equivalent cannibalising impact of about 5% of sports betting handle, marking it as a meaningful headwind for licensed sportsbooks.

Why should I read this?

Short version: if you care about customer acquisition, handle or where users are spending attention during big sports moments — this matters. Kalshi isn’t just a niche outlier any more; it’s siphoning downloads and potentially handle away from traditional sportsbooks. Read it so you know what’s eating your growth and why promo budgets might not be working like they used to.

Context and relevance

This story matters to operators, affiliates and investors in iGaming because it signals a shifting consumer preference during peak events. With sportsbooks tightening promotions to prioritise profitability, prediction markets have room to grow and to steal engagement that would otherwise flow to fixed‑odds apps.

If the trend continues, expect operators to: adjust acquisition tactics, experiment with product differentiation (including in‑app markets or microbetting), and reassess marketing spend during marquee fixtures. Regulators and market entrants should also watch the space closely — changing product mix can shift revenue and risk profiles across the sector.
