Navalnaya's overnight Polymarket surge revives the Nobel leak question

A move from long shot to favourite in one night ^[1] had to be bought, and the sources show the bill only in aggregate. Navalnaya's contract drew more than $1.7m ^[4] out of just over $30m traded on the whole event ^[5], or roughly 6% of its turnover ^[13]. Neither publisher says how much of her $1.7m changed hands overnight. Her price rose four to thirteen times from its starting range ^[14]. I think a line that small, next to the market around it, takes much less money to lift that far than the event total implies.

The template is 2025. Maria Corina Machado had not been considered a favourite ^[6] when her odds spiked late to near 73%, and she won ^[7]. The two publishers describe that episode with different confidence. Bloomberg, in the Straits Times account, says a leak of her name triggered the surge hours before she was unveiled ^[6]; Crypto Briefing calls the breach suspected and the link to the trading possible ^[11]. This year's high, put at 65.5% to 69% ^[3], sits 4 to 7.5 points below Machado's ^[15].

The pullback, or rather how far it ran before the announcement, is the part I find more informative. A trader who knew the name would have kept buying as the price fell, and both reports have it well off the high ^[17][18]. The counter-case comes from 2025 itself. With a probable leak in the market, Machado's price still topped out 27 points short of certainty ^[16]. Informed money, if that is what moved it, stopped buying early too.

Navalnaya has carried on her husband Alexei Navalny's campaign from exile since his death in an Arctic prison in February 2024 ^[10]. A crowd needs no inside information to back that candidacy the night before a Peace Prize. If Kuleba, Sudan's Emergency Response Rooms or another contender wins ^[12], the spike becomes what Crypto Briefing called "a cautionary tale about crowd momentum" ^[21]. If Navalnaya wins, the price was right and the record still would not show why.

In my view the evidence supports a narrow claim: some buyers became convinced overnight, and the rest of the market would not follow them to the end ^[17][18]. That view is wrong if Navalnaya wins and the Nobel Institute finds that the 2026 name got out early ^[8].
