What each AI says

GPT-5.6 Luna

57% yes

Likely yes — Democrats are modest favorites in current reporting, and Republicans’ narrow majority means a net gain of three seats could flip control. The map remains highly competitive and redistricting complicates the Democratic path, so a Republican hold is a substantial possibility.

Claude Sonnet 5

57% yes

Likely yes but close — multiple reports describe Democrats as modest favorites given historical midterm trends against the incumbent party and ~22 toss-up districts, though redistricting gains for Republicans have narrowed the path. The race is within a few seats, so a small polling miss or late break either way could flip control before the Nov 3 election.

Gemini 3.8 Flash

58% yes

Likely yes — historical midterm dynamics heavily favor the out-party against the president's party, and Democrats need to flip only a net of 3 to 4 seats to reclaim the majority. While Republicans have favorable redistricting lines and a resilient geographic base, the polling and toss-up distribution lean slightly toward a Democratic flip. The main risk is that Republican strength in rural/Sunbelt toss-ups and strong turnout among their base limits Democratic gains to just one or two seats.

Grok 4.6

58% yes

Likely yes — recent reporting through mid-October calls Democrats modest favorites for a narrow majority, and they need only a net gain of three seats amid 22 toss-ups. Redistricting and the GOP’s current 218–214 edge could still hold if the late campaign breaks Republican.

DeepSeek V4 Pro

62% yes

Likely yes — Democrats are modest favorites to flip the House, needing only a net gain of about three seats, and recent reporting describes a narrow but real Democratic edge. The main risk is that the competitive map is highly uncertain, with 22 toss-ups, and redistricting could blunt Democratic gains.

Qwen 3.8 Max

63% yes

Likely yes — Democrats are described as modest favorites by multiple sources, need only 3 net seats, and the historical midterm pattern favors the opposition party. However, redistricting complications and the narrow margin (22 toss-ups) introduce meaningful uncertainty. The main risk to this call is that Republican redistricting advantages and a late-breaking shift could keep the GOP's slim majority intact.

Mistral Medium 3.5

60% yes

Likely yes — Democrats are modest favorites with a narrow but plausible path to flip at least three seats, given the competitive district count and recent polling trends. The main risk is that Republicans hold on in tight races or redistricting advantages tilt the map in their favor.

Kimi K3

62% yes

Likely yes — Democrats are modest favorites in recent reporting and need only a net gain of about three seats, with 22 toss-ups giving them multiple paths to a majority. Redistricting has complicated their path and the margin will be narrow, so this is far from certain. A strong Republican turnout or favorable resolution of the toss-up districts could keep the GOP in control.

GLM 5.3

62% yes

Likely yes — recent October 2026 reporting has Democrats as modest favorites to win the House, consistent with the historical pattern of midterm losses for the president's party. However, redistricting has narrowed the Democratic path and Cook lists 43 competitive districts with 22 toss-ups, so a narrow Republican hold is quite plausible. Late polling shifts or Democratic underperformance in toss-up districts would prove this wrong.

MiMo V2.5 Pro

62% yes

Likely yes — Democrats are rated as modest favorites by recent sources as of mid-October, and the GOP holds a very thin majority with dozens of competitive districts. However, redistricting complications and a large number of toss-ups introduce real uncertainty, so this is far from certain. The main risk to this call is that Republican incumbents outperform expectations in the roughly 22 toss-up races, which would be enough to hold the chamber.

News the AIs read (Oct 15)
- As of 2026-10-15, Republicans control the House, with the chamber reported at 218–214, 219–214, or 219–214 depending on whether an independent who caucuses with Republicans and vacant seats are counted; all sources agree Democrats need a net gain of at least three seats to take control. - The 2026 U.S. House elections are set for 2026-11-03, with all 435 voting seats on the ballot. - Recent reporting dated 2026-10-06 to 2026-10-14 says Democrats are modest favorites to win the House, though the margin is expected to be narrow. - Reuters reporting on 2026-10-12 says Republicans are defending a narrow majority and that redistricting has complicated the Democratic path to control. - NPR reporting on 2026-10-08 says Cook currently lists 43 competitive districts, including 22 toss-ups, underscoring how close the map is. - One source dated 2026-10-14 says there are 215 Democrats and 201 Republicans in its results display, but that appears to be a live election-results page rather than a confirmed seat-count summary, so it should not be treated as the governing count for control. - No injuries, suspensions, or similar team-style factors apply to this question; the key facts are seat count, competitive districts, and the election date.
Resolution rules
This market will resolve according to the party that wins control of the United States House of Representatives in the 2026 United States midterm election. A party wins control of the United States House of Representatives if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the chamber will be deemed controlled by the party with which the first elected Speaker of the House of the Congress that convenes after the 2026 midterm election is affiliated. The following rules govern the counting of seats for determining which party wins control of the chamber. All House elections in the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th Congress are included. Where a seat is decided by a runoff, the runoff result will determine attribution of that seat. Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected. House members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with, a party are included in that party’s count. If the caucus decisions of members of the House elected as independents cannot be determined on the date of the election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party. The resolution sources for this market will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.
