Apple’s probability of becoming the world’s largest company by market capitalization on December 31 stood at 41.6% on Polymarket, up 13.5 percentage points over 24 hours, according to PredictionBubbles. The contract had recorded $1.4M in traded volume.
A sharp move, still below 50%
The price puts Apple’s year-end market-cap leadership below an even chance despite the increase. The supplied material does not identify a catalyst for the move or provide probabilities for competing companies.
The figures accompanied a headline published Oct 29, 2026, at 9:24 PM ET. The summary cites PredictionBubbles’ Oct. 30, 01:11 UTC crawl, which counted 186 open finance markets and $165.3M in traded volume.
Board totals reflect different snapshots
The supplied PredictionBubbles page separately lists 187 open markets, comprising 15 on Kalshi and 172 on Polymarket. That differs from the crawl cited in the summary; the material does not explain the discrepancy. PredictionBubbles says its data refreshes every 15 minutes, while trading on the underlying venues continues between updates.
Across the finance board, the largest contract by total traded volume concerned whether no Fed rate cuts would occur in 2026, with $9.3M traded on Polymarket, according to PredictionBubbles. The site distinguishes volume rankings from rankings based on absolute probability changes over the preceding 24 hours.
PredictionBubbles aggregates prices rather than operating a trading venue. It also cautions that related questions across Polymarket and Kalshi can have different wording and resolution rules, limiting direct comparisons.
What it means for prediction markets
- The repricing is substantial, but not a majority view: Apple’s 41.6% probability remains below 50% after a 13.5-point daily increase.
- Volume and movement measure different things: The $1.4M figure is total traded volume, not the amount traded during the latest probability jump.
- Timing matters: A board refreshed every 15 minutes is a snapshot, not necessarily the latest executable price.
- Contract terms matter: Comparisons with other market-cap leadership contracts should account for wording and resolution rules.
