2. Market Behavior & Price Dynamics

Historical Price (Probability)

Outcome probability
Date
This prediction market has exhibited a clear downward trend since its inception. Opening at a high of 38.0%, the contract's perceived probability has steadily declined, currently trading at 26.0%. The most significant event in the chart's history was a sharp 15.0 percentage point drop on April 21, 2026, when the price fell from 37.0% to a low of 22.0%. This single movement accounts for the majority of the contract's overall price depreciation and represents a dramatic negative shift in market expectations. The price has since seen a minor recovery and has been consolidating around the 26.0% level.
The catalyst for the dramatic price drop on April 21st is not apparent from the information provided, as no specific news or external context is available. The market's volume of 1,808 total contracts suggests moderate but not continuous interest, which can sometimes lead to higher volatility and more pronounced price swings when new information or significant trades occur. From a technical perspective, the market established an early resistance level near its peak of 38.0%. The recent low of 22.0% has now become a key support level to watch. The current price is trading within the range established by this recent, sharp sell-off.
Overall, the price action indicates a strong erosion of confidence in this outcome. The market sentiment has shifted from moderately optimistic at 38.0% to decidedly pessimistic. The sharp, unexplained drop suggests a significant event or piece of information impacted traders' perceptions, even if it is not publicly detailed. The subsequent stabilization indicates that the market is currently reassessing the candidate's chances at this new, lower probability, but the prevailing sentiment remains bearish compared to the market's opening levels.

Market Discussion

Traders are actively discussing the prospects of Ryan Busse, Sam Forstag, and Russell Cleveland for the MT-01 Democratic nomination, with a recent poll placing Busse significantly ahead. Arguments for Busse center on his established name recognition, while Sam Forstag's status as a potential frontrunner is questioned. Despite Forstag's current market share, some traders express surprise that Busse isn't leading given his wider electorate recognition.

5. What are Samuel Forstag's key campaign finance metrics?

In-state Small-Dollar Donation Ratio37.74% [^]
Cash-on-Hand$85,000 [^]
Cash-on-Hand to Operational Expenditures Ratio1.21 times [^]
Democratic candidate Samuel Forstag shows the most favorable in-state, small-dollar donation ratio [^] . Forstag, a Democratic candidate for Montana's 1st Congressional District in 2026, raised a total of $155,000. Of this amount, $65,000 originated from small-dollar donations (contributions under $200), with nearly 90% ($58,500) of these small contributions coming from Montana residents. This results in an in-state, small-dollar donation ratio of 37.74% of his total fundraising haul [^].
Forstag's campaign concluded the period with a robust cash-on-hand figure [^] . He reported $85,000 in cash-on-hand at the close of the most recent filing period. His operational expenditures for the same quarter totaled $70,000, meaning his available cash reserves are approximately 1.21 times his quarterly operational burn rate [^].

6. What Endorsements Has Sam Forstag Secured for MT-01 Democratic Primary?

Largest Union EndorsementMontana Federation of Public Employees (MFPE) [^]
Democratic Legislator Endorsements19 current state legislators [^]
Montana AFL-CIO Endorsement StatusNot publicly endorsed a candidate yet [^]
Sam Forstag has secured significant labor endorsements from Montana's key unions. He has received an endorsement from the Montana Federation of Public Employees (MFPE), recognized as the state's largest union, which also encompasses the Montana Education Association-Montana Federation of Teachers (MEA-MFT) [^]. His campaign further lists endorsements from additional unions, including the International Brotherhood of Electrical Workers (IBEW) Locals 206 and 768, United Food and Commercial Workers (UFCW) Local 4R, Teamsters Local 2, Montana State Council of Machinists and Aerospace Workers (IAMAW), Montana State Association of Letter Carriers (NALC), Montana Nurses Association (MNA), and Boilermakers Local 11 [^]. As of the most recent information, the Montana AFL-CIO has not yet publicly endorsed a candidate for the MT-01 Democratic primary [^].
Forstag also enjoys strong backing from numerous Democratic state legislators. He has publicly received endorsements from 19 current Democratic state legislators whose districts overlap with Montana's 1st Congressional District [^]. These endorsements include State Representatives Dave Fern, Jonathan Karlen, SJ Howell, Katie Sullivan, Danny Tenenbaum, Willis Curdy, Tom France, Paul T. Fielder, Greg Frazer, Andrea Olsen, Sharon Stewart-Peregoy, Kelly Kortum, Derek Harvey, Jennifer Lynch, and Erin Parrish. He also has the support of State Senators Pat Flowers, Shannon O'Brien, Ellie Boldman, and Tom Winter [^]. While State Representative Melissa Romano, who serves as President of MFPE, is listed as an endorser, her legislative district is outside MT-01, making her endorsement primarily notable for her union leadership role [^].

7. What Is Zooey Zephyr's Early TV Ad Spending Strategy?

Total Ad SpendingOver $1 million [^]
Ad Campaign StartMid-October 2024 [^]
Ad Campaign DurationThree weeks [^]
Montana State Rep. Zooey Zephyr's campaign is demonstrating the earliest and most sustained television ad spending in the MT-01 race. Her campaign has committed over $1 million for an early ad buy in the critical Missoula and Bozeman media markets [^]. These advertisements commenced in mid-October 2024 and are scheduled to run for a duration of three weeks [^].
The core message of Zephyr's creative centers on protecting reproductive rights and ensuring access to affordable health care [^] . While Ryan Busse, Russell Cleveland, and Sam Forstag are among the other candidates who have announced their bids for the MT-01 Democratic primary, available research indicates that only Zephyr's campaign has made a significant, early television ad commitment of this scale [^].

8. What Opposition Research Affects Ryan Busse's Campaign?

Primary VulnerabilityPast in firearms industry, now advocates for gun control [^]
Key CriticismNational Shooting Sports Foundation (NSSF) alleges Busse profits from 'attacking gun rights' [^]
April 21st Market Drop LinkNo specific event found to explain a market drop on April 21st [^]
Ryan Busse faces scrutiny for his gun industry shift and advocacy. A Democratic candidate for MT-01, he is subject to significant public opposition research stemming from his history in the firearms industry and subsequent advocacy for stricter gun control [^]. He transitioned from working in the gun industry to becoming a vocal critic, detailing his reasons for leaving and his perspective on the roots of gun violence in the U.S. [^]. This pivot has drawn sharp criticism from pro-gun organizations, particularly the National Shooting Sports Foundation (NSSF), which alleges that Busse 'makes money attacking gun rights' and warns against his congressional run [^]. This narrative frames his current advocacy as financially motivated, potentially undermining his sincerity, especially in a pro-gun state like Montana [^].
Minor issues surfaced, but no direct link explains the price drop. Beyond his firearms industry past, minor issues have surfaced, such as a 1998 citation for hunting birds without a license [^]. While these vulnerabilities could generally impact a campaign, the available research does not provide specific information directly linking any new public surfacing of these issues or any specific opposition research event to April 21st that would definitively explain a major price drop in the prediction market on that exact date [^]. Therefore, despite the identified criticisms, the provided information does not establish a direct causal link to the market movement on April 21st.

9. Are Independent Voter Polling Crosstabs Available for MT-01?

Independent Voter CrosstabsNot available from campaign-released internal polling [^]
Public Poll Zinke vs BusseZinke 47%, Busse 38%, Undecided 15% (Dec 2025-Jan 2026 poll) [^]
Democratic Primary DebateScheduled for a Tuesday in Butte (specific date not detailed) [^]
Campaigns have not released specific internal polling data on independents. There is an absence of campaign-released internal polling crosstabs detailing candidate strength among independent voters for Montana's 1st Congressional District in a hypothetical general election [^]. While public polling has been conducted, such as a Montana Free Press/Eagleton poll from December 2025-January 2026, the specific crosstabs for independent voters in a general election were not detailed in the provided information [^]. This public poll surveyed 400 likely voters with a margin of error of +/- 4.9 percentage points, indicating Republican incumbent Ryan Zinke led Democratic candidates Ryan Busse (47% to 38%) and Monica Forstag (47% to 33%) [^].
A Democratic primary debate is scheduled, but its precise date is unconfirmed. A televised debate for the Democratic primary in Montana's 1st Congressional District is scheduled to take place on a Tuesday in Butte [^]. However, the exact date for this debate has not been explicitly provided in the available sources [^]. The Democratic primary election for this district is set for June 2, 2026 [^].
