What to Know Before You Watch
What Is a Prediction Market?
Platforms where users buy and sell yes/no contracts on real outcomes. If the event happens, the contract pays $1. If not, $0. The price reflects the crowd's implied probability. These are not sportsbooks — they're CFTC-licensed commodity exchanges.
Are These Platforms Legal?
Kalshi and Polymarket are federally licensed by the CFTC as Designated Contract Markets. They operate under the Commodity Exchange Act, not state gambling law — though that distinction is actively contested in courts in Nevada, Illinois, and Michigan. Access varies by state.
Key Terms You'll Hear
“Trade” not “bet” — regulatory language that matters legally. “CFTC” — the federal regulator. “DCM” — the Kalshi exchange license. “Event contract” — the instrument, legally distinct from a sports wager.
How to Evaluate Claims in the Film
- Platform licensing: Kalshi and Polymarket are federally regulated. Check CFTC.gov/PressRoom for original DCM licensing orders.
- “Betting” vs. “trading”: The terminology distinction has real legal stakes. Kalshi disputes Netflix's use of gambling vocabulary like “bet slip.”
- Volume figures: World Cup wagering data should be confirmed at Kalshi's and Polymarket's official data pages or press releases, not third-party estimates.
- Nevada restriction: Kalshi has been barred from offering sports and election contracts in Nevada under a court order since May 2026. This is the context for the disputed documentary scene.
- Pre-premiere context matters: This guide was written before the film aired. Our fact-check section below launches after the July 26 premiere.

Full platform guideThe Legal Landscape the Documentary Covers
The regulatory battle over prediction markets is ongoing as of July 2026. Here's the high-level context:
Federal (CFTC)
Kalshi and Polymarket hold CFTC Designated Contract Market licenses. The CFTC has argued in court filings that its authority preempts state gambling regulation. The 2026 Digital Asset Market Clarity Act (H.R.3633) is pending in the Senate but does not directly address prediction market preemption.
State Courts (Nevada, Illinois, Michigan)
Three states have active litigation restricting Kalshi operations. Nevada has a court-ordered sports and election contract ban since May 2026 — the context for the disputed documentary scene. Michigan and Illinois have their own ongoing cases. Full legality breakdown by state →
What This Means for Viewers
If you want to trade after watching, check whether your state has active restrictions. Kalshi and Polymarket both display state-specific access information at account creation.
