A Kalshi contract on Leylah Fernandez winning was priced at a 78.0% market-implied probability, up 12 percentage points, with $1.6M traded in the Oct 21, 2026 · 6:54 AM ET snapshot. According to PredictionBubbles’ sports-board summary, the contract was among the category’s largest upward moves.

PredictionBubbles ranks probability changes over the preceding 24 hours. The supplied material does not identify Fernandez’s opponent, the event or the contract’s resolution terms, and it provides no explanation for the price increase.

Reading the sports board

According to PredictionBubbles, its sports coverage includes 526 open markets: 191 on Kalshi and 335 on Polymarket. Its embedded visualization displays the 300 largest by traded volume, while the full board covers all 526. The site refreshes its data every 15 minutes, rather than reflecting every trade immediately.

The board separates price movement from trading activity. Its movers ranking uses the absolute change in probability over 24 hours, while its volume ranking uses total traded volume. Fernandez’s $1.6M figure therefore should not be read as the amount traded during the period of the 12-point increase.

PredictionBubbles displays exchange prices rather than setting odds or accepting wagers. It also cautions that related contracts across Kalshi and Polymarket can have different wording and resolution rules, limiting direct comparisons.

What it means for prediction markets

• The price reflects trader expectations, not a confirmed result. The 78.0% reading is a market-implied probability of the contract’s winning outcome.
• The catalyst remains unspecified. The supplied reporting establishes the upward move but does not tie it to match developments or other news.
• Timing and contract details matter. The board’s 15-minute refresh cycle can lag trading, and the missing event and resolution terms prevent a precise assessment of what the Fernandez contract covers.
