Infiniti Intelligence Hourly Briefing — Oct 30, 2026 · 6:54 PM ET

Susan Collins is the underdog in Kalshi’s Maine Senate market, with a 36% probability of securing a sixth term against Democratic challenger Troy Jackson’s 64%, according to Kalshi News. The election is November 3, 2026.

The figures, reported by Kalshi News on October 29, favor Jackson even as the polling cited by the outlet shows a close contest. They represent traders’ assessments of the outcome, rather than projected vote shares.

Polls show a narrow contest

A Marist survey published Oct. 27 put Jackson at 49% and Collins at 47%, according to The Hill’s reporting cited by Kalshi News. That advantage falls within the poll’s 6.6-point margin of error.

A Fox News survey conducted Oct. 16 to 20 recorded 49% support for each candidate. Nate Silver’s Oct. 28 forecast showed Jackson leading by 2.4 points, according to Kalshi News.

Jackson previously served as president of the Maine Senate and comes from northern Maine, where he is a fifth-generation logger. Maine Democrats selected him at a July 2026 convention following the original nominee’s withdrawal, Kalshi News reported. He faces Republican incumbent Collins.

Broader congressional pricing

Beyond Maine, Kalshi News reported a 68% probability of Democrats taking control of the Senate in the platform’s chamber-control market. A separate contract assigned a 66% probability to Democrats winning both the Senate and the House.

What it means for prediction markets

• Jackson is favored, not assured victory: The reported 64%–36% pricing leaves a substantial probability of Collins winning another term.
• Polling and market odds measure different things: The close polling figures describe voter support; the market percentages describe the assessed likelihood of victory.
• Timing matters: These probabilities come from Kalshi News’s October 29 report, not a newly verified October 30 market snapshot.

Andrey Gyurov’s price to win the next Bulgarian presidential election reached 38.5% on Polymarket, rising 19.5 probability points over 24 hours, according to the supplied Oct. 30, 2026 market headline. The headline reported $1.0M traded, but did not specify the period covered by that volume.

The increase marks a substantial change in traders’ assessment, although the price remains below 50%. The supplied material does not identify an election development, poll or announcement behind the move.

Reading the market snapshot

According to PredictionBubbles, its movers board compares prices on Polymarket and Kalshi over 24 hours and updates every 15 minutes. Rankings reflect the size of the probability-point change in either direction, rather than relative percentage gains or trading volume.

The supplied snapshots differ. The summary describes an Oct. 30, 22:57 UTC crawl, using data read at Oct. 30, 22:04 UTC, with 1,991 markets ranked and 524 moving at least 1 point. The source-page extract instead gives a venue-data timestamp of 30 Oct 2026, 22:34 UTC, with 1,997 markets covered and 530 moving at least one probability point; its table displays the top 150.

What the figures establish—and leave open

PredictionBubbles says the board covers markets lasting longer than 14 days and excludes same-week fixtures. Only open markets with a usable 24-hour price comparison qualify. Those filters matter: the rankings are not a comprehensive list of every contract trading on either venue.

The supplied page extract explains the methodology but does not display Gyurov’s individual market entry. His 38.5% price, 19.5-point increase and $1.0M traded therefore come from the supplied headline, rather than an independently visible row in the extract. Neither order-book depth nor election-market settlement terms are provided.

What it means for prediction markets

• The move is measured in points: the reported increase is 19.5 probability points, not a 19.5% relative gain.
• Volume is context, not proof of liquidity: the $1.0M figure does not establish how much traded during the repricing or how readily additional orders could be filled.
• The catalyst remains unverified: the material documents a price change, not an explanation for it or confirmation that Gyurov will win.
• Timestamps matter: the differing board snapshots should not be treated as one simultaneous market reading.
