NBA’s Adam Silver wants prediction-market data to spot insider bets
The NFL has gone further, telling the Supreme Court sports-related prediction contracts are gambling & should carry a trading age of 21.
The hit
NBA commissioner Adam Silver wants access to prediction-market trading data to catch insider bets on games, according to GamblingNews. Silver told CNBC’s Contessa Brewer that prediction markets raise the same integrity concerns as sports betting, singling out contracts on events like coach firings as “odd behavior.”
Why it matters
The NBA wants access to trading data & a single federal framework; the NFL wants state gambling law to apply. Both leagues worry insiders could trade on nonpublic information about player injuries, performance & coaching changes.
The record
| Silver’s comments | CNBC Squawk Box, 9 October (GamblingNews) |
|---|---|
| NFL’s proposed trading age | 21, to match the betting age in many US states |
| NBA’s regulatory footprint | roughly 40 jurisdictions, per Silver |
| Illinois ruling | temporarily blocked state gambling-law application to Kalshi & Coinbase event contracts |
What happens next
Watch the Supreme Court case on state gambling-law jurisdiction over prediction markets, with conflicting court rulings still unresolved.
