Infiniti Intelligence Hourly Briefing — Oct 11, 2026 · 12:54 PM ET

Senate odds soften

Democratic Senate control is priced at approximately 62%, down from 66% a week earlier, according to DeFi Rate. The four-percentage-point decline comes with the midterms 23 days away.

The figures, reported as of Oct 11, 2026, at 12:54 PM ET, show a narrower advantage for Democratic Senate control, though that outcome remains above 50%.

Michigan also moves lower

DeFi Rate’s Michigan Senate reading fell from 72% to 68%, matching the four-percentage-point drop in the Senate-control measure. The supplied summary does not identify which party or candidate the Michigan percentage represents.

House control, meanwhile, stands at approximately 90%, according to DeFi Rate. The summary does not specify the party associated with that figure or provide a prior-week comparison.

With the source page unavailable, the figures establish the direction of the Senate moves but do not explain what drove them.

What it means for prediction markets

• Senate control has become less certain: Democratic control remains the higher-probability outcome at approximately 62%, but its reading has weakened from 66%.
• Michigan shows an equal-sized decline: Its move from 72% to 68% is notable, although the missing outcome label limits interpretation.
• The House comparison is incomplete: The approximately 90% reading is more concentrated than the Senate figure, but the supplied material does not identify the favored party.
• Timing matters: With 23 days until the midterms, these readings are a snapshot rather than a settled result.

October hold remains the favorite

As of Oct 11, 2026, at 12:54 PM ET, Kalshi/Polymarket pricing put an Oct. 28 Federal Reserve rate hike at approximately 15.5–16.5¢, down 2 percentage points this week. A hold stood at roughly 84–85%, leaving unchanged rates as the clear market favorite.

According to defirate.com, the probability of a hold was 84%, while a cut was about 2%. Those figures reinforce the tilt toward no change, although the supplied quotes should not be treated as a single, synchronized probability distribution.

December carried substantially stronger hike expectations. Pricing for a hike at the Dec. 9 meeting was approximately 73–75%, making it the likelier hike meeting compared with October.

The distinction between a displayed trade and an executable price matters. According to defirate.com, Polymarket’s 16.5¢ figure reflected the last trade, and the price available to buyers could differ. The outlet also displayed an illustrative $645 return on $100 if correct, before fees; that illustration should not be read as a guaranteed return at the quoted purchase price.

What it means for prediction markets

• The October move favors a hold: Hike pricing fell 2 percentage points this week, while hold probabilities remained around 84–85%.
• Timing is the central contrast: The approximately 73–75% December hike probability was markedly higher than October’s, indicating a distinction between near-term inaction and later tightening.
• Quote conventions matter: Last-traded prices, current buying prices and pre-fee payout illustrations are different measures. The supplied snapshots do not establish that all outcomes were priced simultaneously.

DeFi Rate’s volume tracker reported $5.2B in trading over 24 hours across 9 prediction exchanges, according to defirate.com. The figure was published on Oct 11, 2026, at 12:54 PM ET.

Volume edges higher

The latest total was up from $5.1B this morning. That puts the reported increase at $0.1B between the two readings.

The figures describe 24-hour volume at each observation, rather than a cumulative total for the day. The increase therefore reflects a change in the tracker’s rolling measure.

How the total is counted

DeFi Rate counts contracts at $1 each when calculating volume. That convention is important: the $5.2B headline is a contract-based measure, not necessarily the amount traders paid for those contracts.

The available summary provides no exchange-level breakdown. It does not identify which of the 9 exchanges contributed most to the total or which markets drove the increase.

What it means for prediction markets

• Measurement matters: The $1-per-contract convention should be considered when comparing this figure with other trading-volume measures.
• The aggregate moved higher: Reported 24-hour volume rose from $5.1B this morning to $5.2B at the latest reading.
• Market-level conclusions remain limited: Without an exchange or contract breakdown, the total does not establish where activity was concentrated.
