NVIDIA’s contract to be the world’s largest company by market capitalization on December 31 was priced at 63.5% on Polymarket, up 4.0 probability points, with $1.5M traded, according to the supplied market update published Oct 26, 2026, at 7:24 PM ET.
According to PredictionBubbles, the December 31 contract appeared among rising finance markets on its movers board. The gain reflects a higher market-implied probability over the preceding 24 hours, rather than a 4.0% relative increase.
The supplied board text separately identifies a contract asking whether NVIDIA will hold the largest-company position on October 31, 2026 as a category’s biggest mover. That is a different deadline from the December 31 contract highlighted in the update; the two should not be treated as interchangeable.
The material does not identify a company announcement or other specific development behind the December 31 repricing. It also does not specify the measurement period for that contract’s reported $1.5M in trading.
PredictionBubbles ranks contracts from Polymarket and Kalshi by their absolute 24-hour probability-point changes, refreshing the board every 15 minutes. The supplied source records a venue-data snapshot of 26 Oct 2026, 22:37 UTC, which precedes the publication time of the market update.
The board’s stated universe comprises 1,991 markets lasting longer than 14 days. Its table displays the top 150 of 503 markets moving at least one probability point. Only open contracts with a valid 24-hour comparison qualify, and trading volume and liquidity do not affect the movement ranking.
Polymarket’s contract on whether Russia will announce a new forced mobilization by December 31, 2026 was priced at 8.0%, down 3.5 percentage points, with $171K traded, in the supplied market update published Oct 26, 2026 at 7:24 PM ET.
The decline indicates a lower market-implied probability for an announcement before the deadline. The accompanying material, however, provides no fresh reporting on Russian mobilization policy that explains the change.
The supplied news-search summary reported no significant new platform headline in the preceding 30 minutes. It described the search results as previously used items or material excluded by the collection process. That limits the evidence for linking the repricing to a specific development; it does not establish that no relevant news occurred elsewhere.
According to predictionbubbles.net, its movers board compares prices over 24 hours and updates every 15 minutes using data from Polymarket and Kalshi. The supplied page records a venue-data snapshot of 26 Oct 2026, 22:37 UTC. It ranks moves by probability-point changes rather than relative percentage changes.
The provided page explains that methodology but does not display the Russia contract’s individual entry. The 8.0% price, 3.5-point decline and $171K traded therefore come from the supplied headline, rather than an independently visible contract listing in the source excerpt.
