Thunder championship pricing diverges sharply between Polymarket and Gemini
Rivo's prediction market arbitrage board, read at 8:54 AM ET on November 4, shows the Oklahoma City Thunder's NBA Championship price as the widest gap among the biggest markets it tracks, at 12.5 cents on Polymarket against 19 cents on Gemini, a 6.5-point spread. The Miami Heat show the next widest gap in the same market, at 1 cent on Polymarket US against 7 cents on Gemini.
The Oklahoma City Thunder had the largest cross-venue price difference among the biggest markets tracked by Rivo’s prediction market arbitrage board, according to Rivo. The board was read at 8:54 AM ET on November 4.
Championship prices differ across venues
The Thunder’s NBA Championship price stood at 12.5 cents on Polymarket and 19 cents on Gemini. That put the spread at 6.5 points in the snapshot accompanying the November 4, 2026 update, published at 10:00 AM ET.
The Miami Heat had the next-largest gap in the same championship market, according to Rivo. Their price was 1 cent on Polymarket US, compared with 7 cents on Gemini.
Gemini therefore showed the higher price for both teams. The comparison also involved different Polymarket venues: the Thunder figure came from Polymarket, while the Heat figure came from Polymarket US.
What it means for prediction markets
- The Thunder’s 6.5-point spread was the widest among the biggest markets Rivo tracked—not necessarily across every prediction market.
- The Heat comparison showed another substantial venue-level difference within the NBA Championship market.
- These figures describe prices at the 8:54 AM ET reading. The supplied summary does not establish whether the gaps persisted or could be captured after trading costs.
