Infiniti Intelligence Hourly Briefing — Oct 28, 2026 · 7:24 PM ET

San Francisco’s contract to win the 2027 Pro Football Championship was priced at a 15.0% implied probability on Kalshi, down 1.0 percentage point over 24 hours, according to PredictionBubbles’ reported market snapshot. Total traded volume stood at $12.1M.

A lower price in a heavily traded contract

The price reflects traders’ assessment of San Francisco’s championship prospects, rather than a probability set by a bookmaker. The supplied material does not identify a specific development behind the decline.

The figures accompanied an Oct. 28, 2026 update published at 7:24 PM ET. The summary cites a PredictionBubbles crawl at 23:12 UTC that covered 552 open sports markets with $794.4M traded.

Board totals reflect different snapshots

The supplied PredictionBubbles page separately lists 569 open sports markets: 204 on Kalshi and 365 on Polymarket. That differs from the crawl cited in the summary, so the two totals should not be treated as one synchronized snapshot. PredictionBubbles says it refreshes its aggregated data every 15 minutes, while trading on the underlying exchanges continues between updates.

The board distinguishes trading activity from price movement: its volume rankings use total traded volume, while its movers rankings use absolute probability changes over the preceding 24 hours. San Francisco’s $12.1M figure therefore measures cumulative trading, not the amount traded during the latest decline.

What it means for prediction markets

• The move is in percentage points: The reported decline is 1.0 percentage point, leaving San Francisco at a 15.0% market-implied championship probability.
• Volume does not explain direction: The $12.1M total indicates trading activity but does not establish what caused the repricing.
• Timing matters: A 15-minute aggregation cycle means displayed prices may differ from current exchange prices.
• Cross-venue comparisons require care: PredictionBubbles notes that related Kalshi and Polymarket contracts can have different wording and resolution rules.

1W sale contract moves higher

Polymarket’s contract on whether commitments to the 1W public sale will exceed $60M was priced at 35.5%, up 12.0 percentage points, with $120K traded, according to the supplied market update published Oct 28, 2026, at 7:24 PM ET.

The increase represents a higher market-implied probability of crossing the $60M threshold—not confirmation that commitments have reached that level. Despite the rise, the contract remained below 50%.

No fresh catalyst identified

The accompanying news-search summary identified no significant new platform headline in the preceding 30 minutes. It reported that search results repeated previously used or excluded material, leaving no fresh reporting in the supplied record to explain the price change.

According to predictionbubbles.net, its movers board measures probability-point changes over 24 hours and refreshes every 15 minutes using venue prices. The supplied page’s snapshot was taken on 28 Oct 2026, at 23:14 UTC. Its rankings cover Polymarket and Kalshi, with trading volume presented as context rather than a factor in ranking moves.

The supplied page explains that methodology but does not display the individual 1W contract entry. The contract’s price, change and traded amount therefore come from the supplied market headline; the source excerpt offers no independent detail on sale commitments or the reason for the repricing.

What it means for prediction markets

• Price is not a commitment tally: The 35.5% reading describes the contract’s implied probability, not the amount raised or committed.
• The change is measured in points: The 12.0-point increase is a probability shift, not a 12.0% relative gain.
• The catalyst remains unverified: Neither the news-search summary nor the source excerpt establishes what drove the move.
• Volume provides limited context: The reported $120K traded does not, by itself, establish order-book depth or explain the repricing.
