About This Event
Tennessee's 7th District If the Republican Party wins the 2026 U.S. House of Representatives election in Tennessee's 7th District by X percentage points or more, then the market resolves to Yes. The margin of victory shall be calculated as follows based on the margin type. For percentage points: the vote percentage received by the Republican Party minus the vote percentage received by the candidate/party/option that finishes immediately behind the Republican Party if the Republican Party wins,
Current Market Outlook
The market is pricing an 84% chance that Republicans win Tennessee's 7th District by 4 or more percentage points in 2026. That is a strong signal. The market sees a blowout as the baseline expectation, not a close race. A 16% chance of a single-digit margin or a Democratic upset means traders are not entirely dismissing the possibility of a tighter contest, but they view it as an outlier.
This district covers parts of suburban Nashville and rural western Tennessee. It has been safely Republican since its creation after the 2020 census. The current representative, Mark Green, won by 38 points in 2022 and 27 points in 2024. The district's partisan lean is R+14 according to the Cook PVI. So the market is pricing a margin well below recent history, which suggests traders expect some regression toward the mean.
Key Factors Driving the Odds
Two things explain the 84% price. First, the district's fundamentals. Trump won this area by 18 points in 2024. The GOP has a structural advantage in voter registration and turnout patterns. A 4-point margin would actually be a relatively poor performance for a Republican here, which is why the market is so confident.
Second, the lack of a serious Democratic challenger. No high-profile Democrat has announced. The district was drawn to be safe for Republicans, and national Democrats have not invested here. Without a well-funded opponent, the Republican candidate will cruise. The 84% reflects that the GOP could nominate a generic candidate and still clear the 4-point threshold easily.
What Could Change These Odds
The biggest risk is a primary challenge that fractures the Republican base. If the incumbent draws a hard-right challenger and the general election becomes a referendum on the incumbent's record, the margin could tighten. That happened in a few safe districts in 2024. But the primary is in August 2026, so there is time for that scenario to develop.
Another risk is a national Democratic wave. If the 2026 midterm becomes a backlash against the Republican president, suburban districts like this one could swing. But the 7th District is not suburban enough to flip. A wave might cut the margin to 8 or 10 points, not below 4.
The filing deadline for candidates is December 2025. If a credible Democrat enters, expect the price to drop toward 70%. If no serious challenge emerges, the price could hit 90%.

Overview
Tennessee's 7th Congressional District covers a swath of Middle Tennessee, including parts of Nashville's western suburbs, all of Montgomery County (Clarksville), and rural areas stretching south to the Alabama border. The district has been held by Republicans since 1873, with the sole exception of a Democratic win in 1994. In the 2024 election, Republican incumbent Mark Green defeated Democratic challenger Megan Barry by a margin of about 59% to 41%, a spread of roughly 18 percentage points. The 2026 race will test whether that margin holds, shrinks, or expands, given demographic shifts in the fast-growing Nashville suburbs and the political environment of a midterm election under a new presidential administration. This prediction market focuses on the exact margin of victory for the Republican candidate, measured as the difference in vote share between the Republican and the second-place finisher. Interest in this market stems from its utility as a bellwether for suburban voting trends in the South and for gauging the relative strength of the two parties in districts that are reliably Republican but not overwhelmingly so.
Historical Context
Tennessee's 7th District has been a Republican stronghold since Reconstruction, with only one Democratic victory since 1873: in 1994, when state representative Ed Bryant defeated incumbent Democrat Bart Gordon in a GOP wave year. Gordon had held the seat since 1985, but after redistricting in 1992, the district became more conservative. Bryant held it until 2002, when he ran for Senate. Marsha Blackburn held the seat from 2003 to 2019, winning by margins ranging from 20 to 40 percentage points. When Blackburn ran for Senate in 2018, Mark Green won the open seat with 51% of the vote against Democrat Justin Kanew, the closest race in the district since 1994. Since then, Green's margins have expanded: 59% in 2020, 60% in 2022, and 59% in 2024. Redistricting in 2022 moved the district slightly north, adding more rural and exurban areas while removing some of Davidson County's more Democratic-leaning precincts. The Cook Partisan Voting Index (PVI) for TN-07 is R+10, meaning it leans 10 points more Republican than the national average. In presidential elections, the district has voted for Republican candidates by margins of 15 to 25 points since 2016.
Why It Matters
The margin of victory in TN-07 matters beyond the district itself because it serves as a proxy for suburban voting trends in the South. The district includes fast-growing suburbs of Nashville, such as Brentwood and Franklin, where populations have increased by 15% since 2020. These suburbs have been trending slightly more Democratic in some areas, but TN-07 has remained solidly Republican. A shrinking margin in 2026 could signal that suburban voters are drifting away from the GOP, while an expanding margin would suggest the opposite. National parties watch these margins to allocate resources for other races. Additionally, the margin affects the national conversation about gerrymandering and representation. If the Republican margin remains above 15 points, it reinforces the district's safe status and reduces pressure for redistricting reforms. If the margin drops below 10 points, it could trigger more aggressive Democratic recruitment and spending in the next cycle. Local impacts include the level of constituent services and federal funding the incumbent can secure; a narrower margin might lead the incumbent to focus more on district-specific issues like Fort Campbell's funding or transportation projects.
Current Status
As of early 2025, Mark Green has not publicly announced whether he will seek reelection in 2026. The Democratic Congressional Campaign Committee has not yet identified a target candidate for the district. The 2026 election will be a midterm under the first year of a new presidential administration, which historically produces a swing against the president's party. In Tennessee, the state legislature is considering new voter ID laws and potential changes to early voting hours, which could affect turnout. The district's boundaries remain unchanged from the 2022 redistricting. No major primary challengers have emerged for either party. The prediction market is currently trading with an implied probability that the Republican margin will be between 15 and 20 points, reflecting the historical trend.
