Kalshi’s “Grants license” outcome for whether a new nuclear reactor will be approved by Dec 31, 2026 was priced at 4.6%, down 2 points, with $836K traded, according to the supplied market snapshot published Oct 23, 2026 at 7:54 PM ET.
The snapshot puts the market-implied likelihood of approval near the bottom of the probability range. The accompanying summary identified no significant new platform headline in the preceding 30 minutes, leaving the material without a clear news explanation for the decline.
According to predictionbubbles.net, its technology-market board displays market-implied probabilities, changes over the previous 24 hours and total traded volume where available. Its data refreshes every 15 minutes, while trading on the underlying venues continues between updates.
The supplied predictionbubbles.net page describes an aggregation service covering Kalshi and Polymarket, rather than reporting a reactor licensing development. It does not provide the reactor contract’s detailed resolution terms or a licensing announcement, so the price movement alone does not establish a change in the approval process.
Apple’s chances of being the world’s largest company by market capitalization on October 31, 2026 were priced at 38.1% on Polymarket, up 10.7 percentage points over 24 hours, according to PredictionBubbles’ finance-board snapshot. The contract had $215K in total traded volume.
The update, published Oct 23, 2026 at 7:54 PM ET, placed the Apple contract among the board’s largest upward finance moves. Despite the increase, its market-implied probability remained below 50%.
PredictionBubbles ranks its movers by the absolute change in probability over the preceding 24 hours. That is separate from its ranking by total traded volume: the Apple contract’s $215K figure represents cumulative trading, not necessarily money traded during the price increase.
The supplied material does not identify what drove the repricing. It includes no accompanying Apple valuation figures or comparisons with other companies, leaving the probability change as the central observable development.
According to PredictionBubbles, the finance board covered 189 open markets at its latest refresh: 22 from Kalshi and 167 from Polymarket. Its data updates every 15 minutes, while trading on the underlying venues continues between updates.
PredictionBubbles displays venue-published prices rather than accepting wagers or holding funds. It also cautions that related contracts across venues can differ in wording, resolution rules and deadlines; the supplied material does not establish a matching Kalshi contract for the Apple question.
