Kamala Harris be first this list to declare for 2028 United States presidential election before Nov 1, 2028 priced at 35.0% on Kalshi, up 22 points, on $6K traded

Harris contract rises without a fresh news catalyst

Kalshi’s contract on whether Kamala Harris will be the first person on its specified list to declare for the 2028 United States presidential election before Nov 1, 2028 stood at 35.0%, up 22 percentage points, with $6K traded. The figures accompanied the Oct 22, 2026 update published at 11:24 AM ET.

The news summary identified no significant new platform headline in the preceding 30 minutes. Search results instead resurfaced a Reuters report on political donations that had already featured in an earlier Oct. 22 update. The supplied material does not include that report’s contents or establish that it caused the price change.

What the move measures

According to predictionbubbles.net, its movers board compares market-implied probabilities over 24 hours and updates every 15 minutes using prices from Polymarket and Kalshi. The supplied page records a venue-data snapshot at 22 Oct 2026, 15:14 UTC.

The site ranks contracts by the size of their percentage-point changes, rather than their relative percentage gains. Trading volume does not determine that ranking. The 22-point increase and $6K traded therefore describe separate aspects of the Harris contract: the extent of its repricing and the reported activity behind it.

The contract’s scope is also narrower than a general question about whether Harris will run. It concerns whether she declares first among a specified list, before the stated deadline. The supplied material does not identify the other people on that list or provide the detailed settlement rules.

What it means for prediction markets

• The price applies to declaration timing. The 35.0% reading is not a probability that Harris wins the nomination or the presidency.
• The catalyst remains unconfirmed. Recirculated Reuters reporting does not, by itself, explain the 22-percentage-point increase.
• Volume provides context, not proof of conviction. The reported $6K traded does not establish order-book depth or explain how the move occurred.
• Contract wording matters. Assessing the outcome requires the specified candidate list and settlement criteria, neither of which appears in the supplied material.
