Polymarket’s $32M Nobel Market Didn’t Anticipate the Peace Prize Winner

Nobody Priced the Eventual Winner

The Norwegian Nobel Committee awarded the 2026 Peace Prize to Navi Pillay on Oct. 9 “for her efforts to promote peace and international law.” On Polymarket, where traders had put $32.3 million into a market on the winner since it opened in October 2025, Pillay was not one of the 70 named candidates.

Donald Trump drew the most money, with $7.96 million traded on whether he would win, followed by UNRWA at $2.1 million and Yulia Navalnaya, the widow of Russian opposition leader Alexei Navalny, at $1.99 million.

Pillay is a former UN High Commissioner for Human Rights, and a former judge at the International Criminal Court and the International Criminal Tribunal for Rwanda. The committee noted that she now sits on the International Court of Justice in the case in which Myanmar is accused of genocide.

Navalnaya traded at about 5 cents through Thursday evening. Starting at around 23:30 UTC, buyers pushed her contract to 54 cents within half an hour, and single trades reached 70.6 cents at 00:02 UTC on Friday, according to Polymarket’s public trade data. The price fell back below 20 cents minutes later and swung between 20 and 30 cents through the morning before going to zero at the 09:00 UTC announcement. A market roundup by RG.org noted that a similar late surge a year ago came before María Corina Machado’s win—but this time, the markets moved in the wrong direction.

Pillay appears now on the resolved market, but there is nuance to this. Her win paid out through the market’s catch-all contract, which until the announcement read “Will any other person or organization win the Nobel Peace Prize in 2026?” After the result, Polymarket relabeled that same contract, created alongside the rest of the market in October 2025, with her name.

It now shows as “Will Navi Pillay win the Nobel Peace Prize in 2026?” with about $38,800 traded, roughly a tenth of a percent of the market. RG.org’s overnight price check found that Pillay was not among the 12 highest-priced names. Kalshi had a smaller book and no catch-all option. Its 2026 Nobel Peace Prize market listed 50 candidates and traded about 5.7 million contracts, with Trump again the most active at 3.06 million. All 50 settled at “no.”

The science prizes went the same way on Polymarket. Its chemistry market named 30 candidates and drew about $60,900, but did not include Henri Kagan or Kenso Soai, who won for asymmetric synthesis. Its physics market named 24 candidates on about $5,300 in volume and left out winner Francis Halzen of the IceCube Neutrino Observatory. Neither market had a catch-all, so every contract settled at “no.”

Kalshi fared better on two prizes: its literature market listed winner Anne Carson and its medicine market listed co-laureate Karl Deisseroth. The economics prize, to be announced Monday, is the last one still outstanding. On Polymarket, about $69,300 has traded across 17 names, with Ariel Pakes leading at 22.5%.

This is a useful case study for the current limits of how prediction markets work: traders can only price the outcomes that are listed by the exchange—and the money follows familiar names. Still, the Nobel Prize markets were a sideshow for an industry whose sports and combo contracts reached $68 billion in a single month this fall.
