About This Event
In 2028 If a representative X party is sworn in as a Senator of Wisconsin for the term beginning in 2029, then the market resolves to Yes. Early close condition: This market will close early following the swearing in of the Senator for the seat in question. This market will close early following the swearing in of the Senator for the seat in question.
Current Market Outlook
Kalshi traders are pricing a Democratic win in Wisconsin's 2028 Senate race at 57%. That is a slight edge, not a lock. A 57% probability means the market sees Democrats as the favorite, but with enough uncertainty that Republicans have a real shot. This is not a blue-leaning state trending bluer. Wisconsin has been decided by less than 1 point in the last two presidential elections and flipped its Senate seat in 2024 when Republican Eric Hovde lost to Tammy Baldwin by just 0.9 points.
Key Factors Driving the Odds
The market is betting on incumbency and national trends. Tammy Baldwin, the current Democratic senator, has not announced whether she will run for reelection in 2028. If she does, she starts with name recognition and a track record of outperforming the national Democratic brand in Wisconsin. She won by 10 points in 2018 and 0.9 points in 2024, both times running ahead of the top of the ticket.
But the 57% number also reflects the state's genuine competitiveness. Wisconsin has gone Republican in 2016, Democratic in 2020, and Republican again in 2024. The state legislature is under firm Republican control, and the state's electoral college votes have flipped twice in three elections. The market is essentially saying "Democrats have an edge, but this is not a safe seat."
What Could Change These Odds
The biggest unknown is Baldwin's decision. If she retires, the Democratic bench is thin. The party lost its most obvious replacement candidates in the 2024 cycle when Governor Tony Evers and Lieutenant Governor Sara Rodriguez both declined to run for Senate. Republicans have a deeper bench here, including 2024 Senate candidate Eric Hovde, who kept the race close despite being outraised 3-to-1.
Watch for the 2026 midterm results. If Republicans gain seats nationally, the 2028 Senate map could shift further right. Wisconsin's Senate race will also be shaped by the 2028 presidential contest, which will drive turnout. A high-turnout presidential year benefits Democrats in Wisconsin, but only if their candidate can actually win the state.

Overview
The 2028 Wisconsin Senate election will determine who represents the state in the United States Senate for the term beginning in January 2029. Wisconsin is a perennial battleground state, and its Senate races are often decided by razor-thin margins. The incumbent, Republican Ron Johnson, was first elected in 2010 and won reelection in 2016 and 2022. He has stated he will not seek a fourth term in 2028, making this an open-seat contest. The election will be held on November 7, 2028, and the winner will be sworn in on January 3, 2029. The race is expected to be one of the most expensive and closely watched Senate contests in the country, with both national parties investing heavily. Control of the Senate could hinge on this seat, as the chamber is often closely divided. Wisconsin's electorate is roughly evenly split between Democrats and Republicans, with a significant bloc of independent voters who decide elections. The state's political geography features a Democratic stronghold in Milwaukee and Madison, and Republican dominance in rural areas and the WOW (Waukesha, Ozaukee, Washington) counties surrounding Milwaukee. The 2028 race will likely focus on economic issues, healthcare, abortion rights, and the direction of the Supreme Court. Both parties are already recruiting candidates, and the primary elections will take place in August 2028. The outcome will have major implications for federal policy on issues ranging from taxes to immigration to judicial appointments.
Historical Context
Wisconsin has a long history of close Senate elections. In 2016, Ron Johnson defeated former Senator Russ Feingold by 3.4%, a rematch of their 2010 race which Johnson won by 5.6%. In 2018, Tammy Baldwin won reelection by 10.8%, a relatively comfortable margin. The 2022 race was the most expensive in state history, with Johnson and his opponent Mandela Barnes spending over $200 million combined. Johnson won by 1.0%, the smallest margin of any Senate race that cycle. The state has voted for the winner of the presidential election in every cycle since 1984, except 2000 and 2004. In 2020, Joe Biden won Wisconsin by 0.6%, and Donald Trump won it in 2016 by 0.8%. This volatility makes the state a bellwether. The 2028 race will be the first open Senate seat in Wisconsin since 2010, when Feingold was defeated. Open seats often attract more candidates and higher spending. The last time an open Senate seat was contested in Wisconsin was 2000, when Herb Kohl won his third term. The state has not elected a Republican to an open Senate seat since 1980, when Bob Kasten won. Democrats have held the seat from 1957 to 2011, except for Kasten's term from 1981 to 1987.
Why It Matters
The 2028 Wisconsin Senate election will likely determine which party controls the Senate for at least the first two years of the next presidential term. The Senate is currently split 51-49 in favor of Democrats (including independents who caucus with them), but several Republican-held seats are up in 2028 in states like Texas and Florida, while Democrats defend seats in Montana and West Virginia. A Republican pickup in Wisconsin could give the GOP a working majority. Control of the Senate affects the confirmation of federal judges, including Supreme Court justices, as well as Cabinet positions and agency heads. The winner will also influence legislation on taxes, healthcare, climate change, and voting rights. For Wisconsinites, the senator will shape federal spending on dairy subsidies, Great Lakes restoration, and infrastructure. The outcome will signal the national mood heading into the 2030 midterms. A Democratic win would reinforce the party's hold on the Midwest, while a Republican win could cement the state's shift to the right. The race will also test the strength of both parties' ground games and the effectiveness of their messaging on economic and cultural issues.
Current Status
As of early 2025, no major candidates have officially declared for the 2028 Wisconsin Senate race. Ron Johnson has reiterated that he will not run again. On the Democratic side, Governor Tony Evers is seen as a potential candidate, but he has not made any public moves. U.S. Representative Mark Pocan and state Attorney General Josh Kaul are also mentioned as possibilities. On the Republican side, former Governor Scott Walker and former Lieutenant Governor Rebecca Kleefisch are considering runs, as is businessman and 2022 gubernatorial nominee Tim Michels. The primary elections will be held in August 2028, and the general election is on November 7, 2028. The race is expected to be one of the most competitive in the country, with both parties already preparing their campaign infrastructure.
