From sports to pop culture: Prediction markets $1 trillion bet

Market Volume and Growth Trajectory

• Weekly prediction market (PM) volume reached $13 billion as of early July 2026, implying a $670 billion annualized run rate.
• PM volume doubled between the start of May and the most recent week, representing a 60x increase in the seven-day period compared to one year prior.
• Eilers and Krenek (gaming consultancy) forecast total PM volume could reach $1 trillion by 2030.
• Approximately 50% of current PM volume is attributed to the FIFA World Cup, with roughly 80% of total value concentrated in sports categories.
• PM volume is currently approaching parity with the projected $160–$170 billion handle of the traditional U.S. online sports betting (OSB) market for the year.

Market Mechanics and Consumer Economics

• The "handle" metric for PMs is roughly four times higher than OSB handle due to the inclusion of both maker and taker sides in volume calculations.
• Consumer costs on PMs (typically ~1–4% embedded spread plus ~2% platform fee) are currently comparable to the ~4.5% "vig" found on OSB platforms like DraftKings or FanDuel.
• PMs offer a distinct advantage for professional "sharp" bettors via lower market-maker fees (30–40 basis points) and the ability to trade without risk of account limits or bans common on OSB platforms.
• No fee compression has been observed on Kalshi's 2% market-taker fee despite increased entrants, though further competition is anticipated.

Category Expansion and Demographics

• Institutional growth is driven by "KPI markets" allowing hedge funds to hedge specific earnings line items (e.g., customer acquisition counts) without trading the underlying stock.
• Retail growth is concentrated in crypto perpetuals, with markets nearing $2 billion in monthly volume, including high-frequency 15-minute price direction bets.
• Pop culture markets (e.g., Taylor Swift wedding details, reality show contestant longevity) are expanding into non-traditional demographics, specifically targeting female users to widen the Total Addressable Market (TAM).
• Sports betting demographics are historically 90% male aged 18–35; pop culture markets aim to diversify this base.

Incumbent Strategy and New Entrants

• DraftKings: Launched the DKX vertically integrated exchange; currently holds ~2% market share since March, leveraging existing state licenses to operate in the 50% of U.S. states without legal OSB (e.g., California, Texas).
• FanDuel: Operating a joint venture with the CME Group, scheduled for a major marketing push at the start of the NFL season.
• Robinhood: Previously drove 60% of Kalshi volume; now holds ~20% and launched its own exchange, "Rothesa," in partnership with Susquehanna International Group (SIG).
• Other Entrants: Polymarket, Coinbase, and Crypto.com have intensified marketing pushes, contributing to volume surges during the World Cup.
• Incumbents are moving toward a "fee-only" revenue model for PMs to avoid the directional risk and volatility inherent in traditional OSB betting.
• Incumbents plan to utilize their pricing expertise to act as market makers on both their own exchanges and third-party platforms like Kalshi.

Customer Acquisition and Retention

• Kalshi gained 4 million new app downloads during the World Cup, reaching the #1 spot on the overall App Store for over a week.
• DraftKings added 800,000 new users to its unified app, combining sports betting and prediction markets.
• DraftKings introduced a Spanish-language app to capture demographic segments previously underpenetrated by OSB operators.
• Operators are offering aggressive promotions (e.g., "$5 to get $350") during the World Cup, with expectations to retain users for the upcoming college football and NFL seasons.

Regulatory Risks and Legal Landscape

• Prediction markets face 15–20 lawsuits across various states, primarily regarding tax revenue loss and consumer protection.
• Key regulatory disputes involve age restrictions (18+ for PMs vs. 21+ for OSB) and gambling addiction safeguards.
• Active Legal Cases:
  • New Jersey: Ruled in favor of Kalshi; a dissenting opinion suggests a path to the Supreme Court.
  • Nevada: Waiting on a decision regarding state bans on PMs.
  • Maryland: Case currently in federal circuit court.
  • Michigan: A temporary restraining order was recently issued against sports event contracts.
• Market participants anticipate a U.S. Supreme Court decision regarding the legality of sports event contracts on PMs by late 2027 or early 2028.
• Potential legal outcomes include a split ruling based on the "economic hedge" argument, where markets with tangible economic consequences (e.g., betting on bar revenue impacts) are distinguished from player prop bets.
