## Content

As of April 20, 2026, the 9th Circuit merits ruling on Kalshi v. Nevada remains pending after the April 16 hearing. Industry lawyers anticipate the dispute will reach the Supreme Court "by next year."

**Circuit split structure:**
- **3rd Circuit** (New Jersey case): Ruled 2-1 in Kalshi's favor — federal preemption prevails
- **9th Circuit** (Nevada case): Panel appeared to lean Nevada's way at April 16 hearing; ruling still pending
- If 9th Circuit rules against Kalshi: explicit circuit split exists, making SCOTUS certiorari "ripe"

**Key legal questions framed for SCOTUS:**
1. Whether state gambling authorities can regulate prediction markets or if federal oversight preempts them
2. Whether Kalshi's sports contracts qualify as "events contracts" (swaps) rather than traditional gambling
3. How Dodd-Frank post-2008 financial crisis regulations apply to prediction markets

**Industry lawyer assessment:** "a true jump ball" — outcome genuinely uncertain at each stage.

**Timeline:** If 9th Circuit rules against Kalshi → Kalshi petitions SCOTUS (likely within months) → SCOTUS decides whether to take the case (requires 4 justices) → full briefing and oral argument (12-18 months if taken). Industry expects resolution "by next year" = 2027 at earliest.

## Agent Notes

**Why this matters:** The SCOTUS path means regulatory uncertainty for prediction markets extends at minimum 12-18 months. Living Capital vehicles launching in 2026 will operate under unresolved jurisdictional ambiguity throughout their early formation phase. This is a real operational risk, not just theoretical.

**What surprised me:** The Fortune framing explicitly positions this as analogous to other post-Dobbs federalism fights — the prediction market/federal jurisdiction question is being litigated as a federalism case, not primarily as a financial regulation case. This framing could attract SCOTUS interest beyond the financial regulation context.

**What I expected but didn't find:** Any indication that the SCOTUS path might be avoided through legislative resolution (GENIUS Act or similar). The article doesn't mention pending legislation as an alternative to judicial resolution — suggesting the courts are the primary arena.

**KB connections:**
- The 3rd Circuit (New Jersey) precedent is currently pro-prediction markets. If SCOTUS accepts and reverses, this could retroactively harm Kalshi even in states where it currently operates.
- Relates to existing claims about regulatory bifurcation — federal-friendly vs. state-enforcement-aggressive. A SCOTUS loss would collapse this bifurcation.
- Timeline implications for Living Capital: a 2027 SCOTUS ruling means the vehicle design must accommodate 3+ years of jurisdictional uncertainty.

**Extraction hints:**
- Claim candidate: "Prediction market federal jurisdiction dispute is tracking toward SCOTUS by 2027, creating 12-18 months of irreducible regulatory uncertainty for platform operators"
- The "true jump ball" framing from industry lawyers is notable — this is not a case where one side has an obvious legal advantage. The KB should reflect this genuine uncertainty.

**Context:** Fortune published this April 20 — two days after the 9th Circuit merits hearing. This is the mainstream financial press framing. Industry lawyers quoted are from the sports betting/gaming law bar.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: Existing claims about CFTC preemption as regulatory protection and federal-state regulatory bifurcation
WHY ARCHIVED: SCOTUS path is now concrete, not speculative. 2027 resolution timeline has direct implications for vehicle design decisions. The "true jump ball" framing from industry lawyers should update KB confidence levels downward on regulatory defensibility claims.
EXTRACTION HINT: The key claim is about timeline and uncertainty: 12-18 months of irreducible jurisdictional ambiguity, not permanent resolution. Frame it as a risk quantification claim, not a directional prediction.
