Kimi Antonelli be the 2026 F1 Drivers' Champion priced at 99.7% on Polymarket, up 0.3 points, on $5.2M traded

Kimi Antonelli’s market-implied probability of winning the 2026 F1 Drivers’ Championship stood at 99.7% on Polymarket, up 0.3 percentage points, with $5.2M traded, according to the supplied market snapshot published Oct 26, 2026 · 8:09 PM ET.

The price puts the contract close to its upper probability limit. It reflects traders’ assessment of the championship outcome, rather than confirmation that Antonelli has secured the title.

No fresh catalyst identified

The accompanying news summary reported no significant new platform headline in the preceding 30 minutes. Its search returned only material already used that day or excluded from the current batch, leaving no fresh reporting in the supplied material to explain the price increase.

The source excerpt also contains no Antonelli-specific race result, championship standings or contract-resolution update. The move can therefore be described as a market development, but not attributed to a particular sporting event.

Reading the market snapshot

According to predictionbubbles.net, its sports dashboard aggregates exchange prices from Polymarket and Kalshi and refreshes its data every 15 minutes. The site describes probability changes as percentage-point moves over the preceding 24 hours and volume as total trading activity where the venue reports it.

That distinction matters here: the $5.2M figure is cumulative traded volume, not a measure of money newly committed during the price increase. Likewise, a periodically refreshed dashboard is a snapshot of a continuously trading market, rather than a guarantee of the price available afterward.

What it means for prediction markets

• Near-certainty is priced in, not established as fact. The 99.7% reading represents the market’s assessment; the supplied material does not confirm the championship outcome.
• The catalyst remains unverified. No fresh Antonelli-specific reporting was provided to explain the 0.3-percentage-point increase.
• Timing and contract terms matter. According to predictionbubbles.net, related contracts across venues can have different wording and resolution rules, while its displayed prices refresh every 15 minutes.
