What Prediction Markets Are Forecasting
Traders on Kalshi see roughly a 19 in 20 chance that Kim Schrier advances past the primary in Washington's 8th Congressional District. That's a 95% probability, which is about as close to a sure thing as primary predictions get. The market asks who will finish in the top two, since Washington uses a "top-two" primary system where all candidates run together regardless of party.
Why the Market Sees It This Way
Schrier is the incumbent Democratic representative in a district that covers parts of King and Pierce counties, including suburbs east of Seattle like Sammamish and Issaquah. She first won in 2018, flipping a seat held by Republicans for years. She has won reelection three times since, each time by a narrow but consistent margin.
Washington's top-two primary means the two candidates with the most votes advance to the general election, regardless of party. In practice, that usually means one Democrat and one Republican. Schrier faces no serious Democratic challenger, so the question is whether she finishes first or second. The market sees her advancing as nearly certain because her name recognition, fundraising, and incumbency give her a huge advantage over any primary opponent.
The bigger uncertainty is who finishes second. Several Republicans are expected to run, including candidates who ran in 2024. That race is more competitive and less predictable than Schrier's own chances.
Key Dates and Events to Watch
The primary is scheduled for August 2026. Filing deadlines will come in spring 2026. The main things to watch: whether any well-funded Republican challenger enters the race, and whether national political trends shift. If the national environment turns strongly against Democrats, Schrier's general election prospects could weaken, but her primary advance looks solid regardless.
How Reliable Are These Predictions?
Prediction markets are generally reliable for incumbent primary races like this one. Incumbents almost always advance in top-two systems. The 95% figure reflects genuine near-certainty, not overconfidence. That said, surprises happen. A scandal or a sudden retirement could change everything. But based on the information available now, the market is giving Schrier's primary advance the same level of confidence as a coin landing on heads twice in a row.
Current Market Outlook
Kalshi traders are pricing Kim Schrier’s advancement in the 2026 WA-08 primary at 95%. That’s not a bet on whether she wins—it’s a bet she finishes in the top two. Washington uses a nonpartisan blanket primary where all candidates appear on the same ballot, and the two highest vote-getters advance regardless of party. A 95% probability means the market sees Schrier’s elimination as a near-impossibility, roughly a 1-in-20 event. The remaining 5% accounts for a scandal, health issue, or a surprise third-party surge that knocks her to third place.
Key Factors Driving the Odds
WA-08 is the most competitive House district in Washington. It flipped from Republican to Democrat in 2018 when Schrier, a physician, won by 5 points. She’s held it since, winning by 4 points in 2022 and 6 points in 2024. The district covers parts of King and Pierce counties including suburban Seattle exurbs like Sammamish and Issaquah. It’s a D+1 district by Cook PVI, meaning it leans Democratic but narrowly.
Two structural advantages protect Schrier in the primary. First, incumbents in Washington primaries almost always advance. Since 2012, only three sitting House members have failed to make the top two in their primary. Second, the Democratic vote in WA-08 tends to consolidate behind Schrier while the Republican vote splits among multiple candidates. In 2024, four Republicans ran, pulling 48% combined while Schrier took 52% alone. As long as Schrier holds Democratic voters, she clears the top-two bar easily.
What Could Change These Odds
The 5% downside comes from two scenarios. A credible Democratic primary challenger could siphon 10-15 points from Schrier, narrowing her margin for error if Republicans consolidate behind a single strong candidate. That hasn’t materialized yet. Alternatively, a national Republican wave in 2026 could drive turnout heavily toward GOP voters, pushing Schrier into third if two Republicans run strong campaigns.
The primary is in August 2026. Watch for candidate filing deadlines in May. If no serious Republican unifies the party base early, Schrier’s odds stay near 100%. If a well-funded GOP challenger emerges and a Democrat enters the race against Schrier, the probability could drop to 85-90%. But 95% accurately reflects the historical inertia of incumbency in Washington’s primary system.

Overview
Washington's 8th congressional district covers the central Cascade range, including Chelan, Kittitas, and parts of King and Pierce counties. The district has been represented by Republican Kim Schrier since 2019, when she flipped the seat from Republican Dave Reichert. The 2026 primary will determine which two candidates advance to the general election. Washington uses a top-two primary system where all candidates, regardless of party, appear on the same ballot, and the top two vote-getters move to the general election, regardless of party affiliation. The 8th district is considered a competitive swing district, having voted for Democratic presidential candidates in 2020 and 2024 while also electing a Republican House member in 2016. The district's partisan lean is roughly even, with a Cook Partisan Voting Index of D+1. The 2026 primary will be held in August 2026, with the general election in November. The outcome will signal which party has momentum heading into the general election and could determine control of the House in the 119th Congress.
Historical Context
Washington's top-two primary system was established by Initiative 872 in 2004 and first used in 2008. The system replaced the previous blanket primary that had been ruled unconstitutional by the U.S. Supreme Court in 2000. Under the top-two system, candidates from all parties appear on the same ballot, and the top two vote-getters advance to the general election, regardless of party. This has led to general elections where both candidates are from the same party, most notably in the 2010 U.S. Senate race where two Democrats advanced. The 8th district was created in 1983 after the 1980 census. It has been represented by Republicans for most of its history, with the exception of Schrier's tenure. The district has trended Democratic in presidential elections, voting for Barack Obama in 2008 and 2012, Hillary Clinton in 2016, Joe Biden in 2020, and Kamala Harris in 2024. However, it has also voted for Republican House candidates in 2010, 2012, 2014, and 2016. The 2020 primary saw Schrier and Larkin advance, with Schrier winning the general by 4 points. In 2022, Schrier and Larkin again advanced, with Schrier winning by 3 points. The 2024 primary saw Schrier and Republican Carmen Goers advance, with Schrier winning by 3 points.
Why It Matters
The 8th district is one of the most competitive House districts in the country. Control of the House of Representatives often hinges on a handful of swing districts, and WA-08 is a key battleground. The outcome of the primary will determine which candidates face off in the general election, and that matchup will influence national campaign spending. Both parties are likely to spend tens of millions of dollars on the race. The district's voters are independent and moderate, making it a bellwether for national political trends. If Schrier loses the primary, it would signal a shift to the left in the district. If a Republican wins, it would be a pickup opportunity for the GOP. The district's economy is driven by technology, agriculture, and tourism. Voters are concerned about the cost of living, healthcare, and education. The primary results will also test the influence of outside groups and the effectiveness of different campaign strategies.
Current Status
As of early 2025, no candidates have officially declared for the 2026 primary. Incumbent Kim Schrier is expected to run for reelection. On the Republican side, Matt Larkin is likely to run again, and other potential candidates are considering their options. The primary is scheduled for August 2026. The filing period typically opens in May 2026. National party committees are already fundraising and planning for the race. The outcome will depend on candidate recruitment, national political conditions, and local issues.
