Michigan Senate (Dem) slips to 68%, down 6 points in 7 days — biggest move on the board

Michigan leads the weekly moves

The Michigan Senate Democratic contract was priced at 68% on Kalshi in DeFi Rate’s Oct. 12 snapshot, observed at 10:52 AM ET. That was down from 74% over seven days, according to DeFi Rate.

The 6-percentage-point decline was the largest seven-day move among the contracts tracked in that snapshot. Michigan therefore stood out for the size of its repricing, even as the Democratic contract remained above 50%.

A snapshot, not an explanation

The supplied summary establishes the contract’s level and weekly change but does not identify what drove the decline. It provides no polling, campaign developments or trading-volume figures to explain the move.

The underlying defirate.com page text was unavailable. The report, published Oct. 12, 2026, at 10:54 AM ET, consequently offers a narrow view: a notable weekly shift rather than a detailed account of the market’s path.

What it means for prediction markets

• A lower Democratic assessment: The move from 74% to 68% reflects a 6-percentage-point reduction in the contract’s market-implied probability over seven days.
• The ranking has limits: Michigan’s decline led the tracked contracts in DeFi Rate’s snapshot; that does not establish it as the largest move across all prediction markets.
• The cause remains unestablished: Without additional reporting or trading data, the snapshot cannot show whether the change reflects new information, shifts in participation or other factors.
