Longshots Losing 98% of Time Dominate Kalshi, Polymarket Trading

Around half of Kalshi trading volume involves bets with potential returns of at least 1,000%. Since early 2025, money staked on “yes” longshots has lost 15% on Kalshi and 27% on Polymarket, indicating poor outcomes for bettors.

Analysis

The key economic signal is not that bettors lose on longshots, but that high-payout contracts may generate substantial turnover while degrading user outcomes. That can support platform engagement, but it does not establish attractive economics: volume is not revenue, and the article provides no fee, retention, or customer-acquisition data. If repeat losses drive users away, apparent activity could be front-loaded rather than durable.

Over the next 1–3 months, the main risk is regulatory and reputational: conspicuous, repeated losses could invite scrutiny of how prediction markets market extreme payouts and assess customer suitability. That could raise compliance costs or constrain product design, even if the underlying contracts remain available. Over 6–18 months, sustained activity could help prediction markets compete with sportsbooks for speculative customers; conversely, poor retention or tighter rules could benefit established gambling operators. Neither outcome is demonstrated by the reported loss figures.

Contrarian point: these losses do not by themselves imply platform profitability or a deterioration in user economics across all contracts. Nor do they establish that platforms take the opposite side; losses may accrue to counterparties. With no company-specific financial or exposure data, this is a sector watch item, not a clean public-equity signal.

Key Decisions for Investors

• No direct trade on this evidence. Do not infer operator revenue or margins from trading volume or bettor losses; first verify fee capture, market-maker economics, and whether reported losses are gross or net of fees.
• Track any publicly traded distributor or broker that offers prediction-market access only after confirming revenue exposure and user activity. A material share of speculative, longshot-driven volume could be a growth signal initially but a regulatory and retention liability later.
• Watch for platform disclosures or regulatory actions over the next 1–3 months concerning user losses, marketing, or contract availability. A restriction on high-payout contracts would falsify the engagement-upside thesis; stable access alongside improving repeat-user metrics would weaken the churn concern.
