Kalshi is 4 points higher than Polymarket (35% vs 32%). Polymarket trades about 3.5× more volume today, so its price has more money behind it. They resolve on different dates (Jan 1 vs Apr 1), so they may not be exactly the same bet.
History starts when we first saw each market, so a newly added market has a short line.

Resolution rules: read both before trusting a gap
Kalshi
If Jensen Huang announces after market issuance and before Jan 1, 2027 that they have left or will leave the board of NVIDIA Corporation (NVDA), then the market resolves to Yes.
Polymarket
This market will resolve to "Yes" if Jensen or Lori Huang file for divorce or announce their definitive intention to divorce by March 31, 2027, 11:59 PM ET. Otherwise, this market will resolve to "No". An announcement from either Lori or Jensen Huang, or their official authorized representatives, of their definitive intention to divorce will be sufficient for a "Yes" resolution, regardless of when or whether the divorce ultimately occurs. Announcements that they are considering or open to a divorce will not qualify. The resolution source will be statements from Jensen Huang and/or Lori Huang, and their representatives, as well as relevant court records; however, a consensus of credible reporting may also be used.
