Prediction markets as corporate hedges: who decides payouts?

Trading desks are buying prediction-market ‘Yes’ contracts priced around $0.10 for a $1 payout to hedge specific corporate losses. The contracts behave like binary options: a winning share redeems for $1 and a losing share is worthless. Large hedges face a central constraint: order-book depth.

A desk facing a $1 million loss would need roughly 1.11 million winning contracts because each winning share nets $0.90 after the $0.10 purchase cost. At the quoted price that trade would cost about $111,000, but that figure assumes a platform can supply more than a million contracts near $0.10 without moving the price.

Institutional activity has risen. Combined monthly volume across Kalshi and Polymarket increased from $7.2 billion in January to about $14 billion by June. Kalshi reported an 800% increase in institutional trading volume over six months, completed its first customized block trade and announced employment-disclosure requirements and a whistleblower portal on June 9. Some money managers are testing markets tied to scheduled economic releases and regulatory outcomes and sometimes pair them with offsetting positions elsewhere in their portfolios.

Risk managers point to several failure modes. Liquidity risk occurs when a large order moves the price and raises hedge cost. Basis risk appears when a contract’s wording diverges from the economic event it was meant to track; one market resolved ‘No’ after a firm disclosed selling 32 BTC because resolution rules focused on the timing of public confirmation. Resolution risk arises when a dispute process determines the outcome; one Polymarket contract tied to a Ukraine minerals deal moved from single-digit implied probability to 100% and then resolved ‘Yes’ while disagreement persisted over whether the agreement had been finalized.

Governance concentration affected contested outcomes. Over three years, nine wallets accounted for about half of the UMA tokens used in dispute votes on Polymarket. After high-profile disputes, UMA shifted toward an allowlisted proposer model to reduce who can propose resolutions. Some market operators are writing contracts keyed to verifiable, objective data sources to limit interpretive disputes.

Regulatory developments are under way. The Commodity Futures Trading Commission released draft rules on June 10 that would formalize federal oversight of certain prediction markets. States and other parties continue to debate limits and disclosure expectations for these venues.

Marcin Kazmierczak, co-founder at RedStone, listed liquidity depth, legal and counterparty clarity, and settlement integrity as the barriers institutions focus on. Eneko Knorr, chief executive of Stabolut, argued that buying a contract tied directly to a specific adverse event removes the need to estimate how proxies would move across a portfolio.

Market participants say they require deeper order-book liquidity, precise contract language that maps to the economic exposure, and a reliable dispute-resolution process before placing hedges large enough to offset corporate losses.
