# Rhode Island Republican Senate nominee? In 2026 Updated: April 29, 2026 Category: Elections Tags: Primaries HTML: /markets/elections/primaries/rhode-island-republican-senate-nominee/ ## Short Answer **Key takeaway.** Both the **model** and the **market** overwhelmingly agree that Raymond McKay will be the Rhode Island Republican Senate nominee, with only minor residual uncertainty. ## Key Claims (January 2026) **- - Raymond T.** McKay is actively campaigning for the U.S. Senate. - Allen Waters is currently campaigning for a U.S. House of Representatives seat. - McKay's Q1 2024 FEC report indicated zero cash-on-hand. - Allen Waters' 2020 primary vote lagged typical Republican support. - The 2026 Rhode Island Republican State Convention deadline is July 25. ### Why This Matters (GEO) - AI agents extract claims, not arguments. - Improves citation probability in summaries and answer cards. - Enables fact stitching across multiple sources. ## Executive Verdict **Key takeaway.** **Model** estimates **96.6%** vs 87c **market** price (+9.6-point gap), favoring McKay as the only active Senate candidate. ### Who Wins and Why | Outcome | Market | Model | Why | | --- | --- | --- | --- | | Allen Waters | 7.0% | 3.4% | Allen Waters is currently campaigning for a U.S. House seat, not the Senate. | | Raymond McKay | 87.0% | 96.6% | Raymond McKay is an active candidate for the U.S. Senate in Rhode Island. | ## Model vs Market | Outcome | Market Probability | Octagon Model Probability | | --- | --- | --- | | Allen Waters | 7.0% | 3.4% | | Raymond McKay | 87.0% | 96.6% | - Expiration: November 3, 2026 ## Market Behavior & Price Dynamics Based on the chart data, this market has exhibited a complete lack of price volatility. The price for the "YES" contract has remained fixed at 87.0% since the market's inception. This perfectly sideways trend indicates that no new information has emerged to alter the market's initial assessment. The absence of any price spikes or drops means there are no specific market-moving events to analyze from the provided context. The price of 87.0% acts as the single, unchallenged key level, functioning as both the floor (support) and ceiling (resistance) for the duration of trading. The trading volume has been relatively low, with a total of 121 contracts traded across 130 data points. The sample data shows periods with zero volume, suggesting that trading activity is sporadic. This low volume, combined with the static price, indicates that while an initial consensus was formed, there is not significant ongoing engagement or conviction from traders to either reinforce this price or challenge it. The market appears to be in a holding pattern, waiting for new developments. Overall, the market sentiment is one of high, stable confidence in the outcome represented by the "YES" contract. The 87.0% probability suggests a strong belief that a particular result will occur. However, the lack of price movement and low trading volume imply this sentiment was established early and has not been tested since. The market is confident, but also quiet and potentially illiquid, reflecting a lack of new information or significant opposing viewpoints. ## Contract Snapshot This market resolves to YES if Raymond McKay wins the Republican Party's nomination for the 2026 Rhode Island Senate seat; otherwise, it resolves to NO. The market opened on July 2, 2025, and will close after the nomination is decided, or by November 3, 2026, at 10:00 AM EST. Outcome verification will be sourced from state governments, and the event is mutually exclusive. ## Market Discussion Limited public discussion available for this market. ## Market Data | Contract | Yes Bid | Yes Ask | Last Price | Volume | Open Interest | | --- | --- | --- | --- | --- | --- | | Allen Waters | 2.3% | 7.6% | 7% | $3,975 | $2,403 | | Raymond McKay | 85% | 87% | 87% | $1,224 | $387 | ## When Will Raymond McKay and Allen Waters Q3/Q4 Fundraising Data Be Public? Q3 2024 Reporting Deadline | October 15, 2024 [[^]](https://www.fec.gov/data/candidate/S4RI00051/), [[^]](https://www.fec.gov/data/candidate/H4RI01141/?tab=other-spending), [[^]](https://www.fec.gov/data/committee/C00827964/?cycle=2024) | Raymond McKay Q1 2024 Cash-on-Hand | $0.00 [[^]](https://www.fec.gov/data/committee/C00827964/?cycle=2024) | Allen Waters Q1 2024 Cash-on-Hand | $18.57 [[^]](https://www.fec.gov/data/candidate/H4RI01141/?tab=other-spending) | **Q3 and Q4 2024 fundraising totals are not yet publicly available** Q3 and Q4 2024 fundraising totals are not yet publicly available. Federal Election Commission (FEC) filings for these periods are not yet due, as the reporting cycles have not fully concluded. Third quarter reports, covering July 1 to September 30, are typically due by October 15, 2024. Fourth quarter reports, spanning October 1 to December 31, are due by January 31, 2025 [[^]](https://www.fec.gov/data/candidate/S4RI00051/), [[^]](https://www.fec.gov/data/candidate/H4RI01141/?tab=other-spending), [[^]](https://www.fec.gov/data/committee/C00827964/?cycle=2024). Current FEC filings show only Q1 2024 financial data for both candidates. Raymond McKay, a Republican candidate for the U.S. Senate in Rhode Island, reported **$0.00** cash-on-hand as of March 31, 2024, in his Q1 2024 filing [[^]](https://www.fec.gov/data/committee/C00827964/?cycle=2024). Allen Waters, who is campaigning for a U.S. House of Representatives seat in Rhode Island's 1st Congressional District, not a Senate seat, reported **$18.57** cash-on-hand as of March 31, 2024, in his Q1 2024 filing [[^]](https://www.fec.gov/data/candidate/H4RI01141/?tab=other-spending), [[^]](https://upgrade.ballotpedia.org/Allen_Waters). Consequently, detailed breakdowns of contributions from Rhode Island-based individual donors for Q3 and Q4 2024 are also currently unavailable, awaiting the passing of their respective reporting deadlines. ## Who Received Endorsements from RI Republican Officials? RI State Central Committee Endorsements | No records of specific public endorsements found (Research findings) [[^]](https://polymarket.com/event/rhode-island-republican-senate-primary-winner/will-allen-waters-be-the-republican-nominee-for-senate-in-rhode-island) | Top 5 Town/City Committee Chair Endorsements | No records of specific public endorsements found (Research findings) [[^]](https://polymarket.com/event/rhode-island-republican-senate-primary-winner/will-allen-waters-be-the-republican-nominee-for-senate-in-rhode-island) | Candidate Endorsement Comparison | Insufficient information to compare endorsements for candidates like Allen Waters or Ray McKay (Research findings) [[^]](https://polymarket.com/event/rhode-island-republican-senate-primary-winner/will-allen-waters-be-the-republican-nominee-for-senate-in-rhode-island) | **Currently, insufficient information exists to compare candidate endorsements from specific GOP officials** Currently, insufficient information exists to compare candidate endorsements from specific GOP officials. Research does not provide sufficient details to determine which candidate, such as Allen Waters or Ray McKay, has secured more public endorsements from current members of the Rhode Island Republican State Central Committee and the official chairs of the five largest town/city Republican committees by voter registration. The available sources lack the necessary specifics for such a comparison. Specific committee membership and endorsement records are currently unavailable. The research does not provide a list of individual State Central Committee members, identify the five largest town/city Republican committees by voter registration, name their official chairs, or contain records of specific public endorsements from these individuals for any candidates. While Allen Waters is mentioned in prediction markets for a 2026 primary [[^]](https://polymarket.com/event/rhode-island-republican-senate-primary-winner/will-allen-waters-be-the-republican-nominee-for-senate-in-rhode-island) and Ray McKay as a U.S. Senate candidate [[^]](https://www.mckayforussenate.com/meet-ray-mckay/), these references do not include endorsement details from party officials. Similarly, details regarding changes in Rhode Island GOP leadership, such as the re-election of a "Powers' Dream Team Slate" [[^]](https://ri.gop/2025/03/01/the-fight-continues-the-powers-dream-team-slate-wins-re-election-to-keep-building-a-stronger-rhode-island-gop/), indicate internal party dynamics but do not enumerate State Central Committee members or their endorsements for primary candidates. Guidance on finding local committees [[^]](https://ri.gop/find-your-local-committee/) also does not detail leadership by voter registration size or list specific endorsements. Therefore, a comparative analysis of support for candidates cannot be performed without explicit documentation of public endorsements from the specified committee members and chairs. ## How Did Allen Waters Perform in Republican Rhode Island Towns? Waters' Avg Primary Vote (Top 10 GOP Towns) | 28.1% [[^]](https://elections.ri.gov/sites/g/files/xkgbur756/files/publications/Data_Files/RIPRIM20Summary.pdf) | Baseline GOP Performance (Top 10 Towns) | 57.2% (2020 Presidential) [[^]](https://uselectionatlas.org/RESULTS/state.php?elect=0&f=0&fips=44&off=0&year=2020) | Waters' Performance Deficit | 29.04 percentage points [[^]](https://uselectionatlas.org/RESULTS/state.php?elect=0&f=0&fips=44&off=0&year=2020) | **Allen Waters' 2020 primary vote significantly lagged typical Republican support** Allen Waters' 2020 primary vote significantly lagged typical Republican support. In the 2020 US Senate Republican primary, Allen Waters competed against Donald F. Carlson [[^]](https://www.ri.gov/election/results/2020/statewide_primary/races/445.html). An analysis of Waters' performance in Rhode Island's ten most Republican-leaning towns revealed a substantial difference compared to the average baseline Republican performance in those areas. His primary vote percentage in these towns averaged approximately **28.1%**, which was significantly lower than the average Republican presidential vote of roughly **57.2%** in the same towns during the 2020 presidential election [[^]](https://uselectionatlas.org/RESULTS/state.php?elect=0&f=0&fips=44&off=0&year=2020). These Republican-leaning towns were identified by 2020 presidential election results. Specifically, the percentage of votes for Donald Trump in the 2020 presidential election was used to determine the top ten Republican-leaning towns [[^]](https://uselectionatlas.org/RESULTS/state.php?elect=0&f=0&fips=44&off=0&year=2020). Waters' average primary vote across these towns was **28.11%**, leading to an average deficit of 29.04 percentage points when compared to the **57.15%** average baseline Republican performance [[^]](https://uselectionatlas.org/RESULTS/state.php?elect=0&f=0&fips=44&off=0&year=2020). Overall, Allen Waters received **28.5%** of the statewide Republican primary vote [[^]](https://www.ri.gov/election/results/2020/statewide_primary/races/445.html). ## What is Raymond T. McKay's U.S. Senate Campaign Messaging Focus? McKay's Primary Messaging Focus | National conservative themes (campaign websites, news article [[^]](https://www.mckayforsenate.com/)) | McKay's RI-Specific Issues Approach | Framed through federal policy impact (news article [[^]](https://www.yahoo.com/news/where-stand-us-senate-candidate-171724273.html)) | Allen Waters' Messaging Data Availability | Not available since January 2024 (Ballotpedia [[^]](https://upgrade.ballotpedia.org/Allen_Waters)) | **For an analysis of campaign messaging, Raymond T** For an analysis of campaign messaging, Raymond T. McKay was identified as a candidate for the Rhode Island Republican Senate nomination, with his campaign websites and a news article providing sufficient material for review [[^]](https://www.mckayforsenate.com/). Allen Waters is also noted on Ballotpedia, but recent campaign websites or social media posts from him since January 2024 were not available in the provided sources, thus preventing an assessment of his messaging themes [[^]](https://upgrade.ballotpedia.org/Allen_Waters). Consequently, the following analysis focuses exclusively on Raymond T. McKay based on the accessible information. McKay primarily emphasizes national conservative themes in his messaging. An examination of his campaign websites and a news article reveals a strong focus on national conservative topics [[^]](https://www.mckayforsenate.com/). As a candidate seeking a seat in the U.S. Senate, his platform naturally addresses federal concerns, including national economic policy, border security, and federal spending, all of which align with established national conservative positions [[^]](https://www.mckayforsenate.com/). Rhode Island issues are framed through a federal policy lens in McKay's messaging. While specific Rhode Island issues are mentioned, they are predominantly presented within the context of how federal policies and decisions would impact the state, rather than as purely local or state-level concerns [[^]](https://www.yahoo.com/news/where-stand-us-senate-candidate-171724273.html). This approach indicates a significantly higher proportion of national conservative themes compared to state-specific issues in McKay's campaign communications. ## What are the key deadlines for the 2026 RI Republican Convention? Convention Date Deadline | On or before July 25, 2026 [[^]](https://vote.sos.ri.gov/Forms/Elections/Guides/2026_ElecCal.pdf) | Primary Election Date | September 9, 2026 [[^]](https://vote.sos.ri.gov/Forms/Elections/Guides/2026_ElecCal.pdf) | Candidacy Declaration Window | July 1 to July 10, 2026 [[^]](https://vote.sos.ri.gov/Forms/Elections/Guides/2026_ElecCal.pdf) | **The 2026 Rhode Island Republican State Convention has a firm July 25 deadline** The 2026 Rhode Island Republican State Convention has a firm July 25 deadline. This key event, where the party officially endorses candidates for offices including U.S. Senate, U.S. Representative, General Officer, and state legislative positions, must take place on or before July 25, 2026 [[^]](https://vote.sos.ri.gov/Forms/Elections/Guides/2026_ElecCal.pdf). Rhode Island General Laws mandate that the state convention be held no later than ninety (90) days before the primary election [[^]](https://law.justia.com/codes/rhode-island/2013/title-17/chapter-17-12/section-17-12-13). Given that the 2026 primary election is scheduled for September 9, 2026 [[^]](https://vote.sos.ri.gov/Forms/Elections/Guides/2026_ElecCal.pdf), the July 25th deadline aligns with this legal requirement. The Republican Party's state committee will ultimately determine the precise date and location for the convention. Candidates interested in filing for the primary election must declare their candidacy between July 1 and July 10, 2026 [[^]](https://vote.sos.ri.gov/Forms/Elections/Guides/2026_ElecCal.pdf). Delegate selection for the convention follows specific state law guidelines. The Rhode Island Republican Party State Convention is composed of several groups: state committee members, Republican members of the House and Senate, Republican general officers, and Republican mayors [[^]](https://law.justia.com/codes/rhode-island/2013/title-17/chapter-17-12/section-17-12-13). Additionally, city or town committee members participate, alongside further delegates chosen by their respective city or town committees [[^]](https://law.justia.com/codes/rhode-island/2013/title-17/chapter-17-12/section-17-12-13). These additional delegates are limited to one for every one thousand (1,000) votes, or major fraction thereof, cast for the party's gubernatorial candidate in the most recent gubernatorial election [[^]](https://law.justia.com/codes/rhode-island/2013/title-17/chapter-17-12/section-17-12-13). For the city of Providence, this calculation is applied uniquely to the votes received for the party's gubernatorial candidate within each individual ward [[^]](https://law.justia.com/codes/rhode-island/2013/title-17/chapter-17-12/section-17-12-13). ## What Could Change the Odds **Key takeaway.** Catalyst analysis unavailable. ## Key Dates & Catalysts - **Expiration:** November 03, 2026 - **Closes:** November 03, 2026 ## Decision-Flipping Events - Catalyst analysis unavailable. ## Related Research Reports - [EU loses a member before 2030?](/markets/elections/international/eu-loses-a-member-before-2030/) - [Who will run for the Democratic presidential nomination in 2028?](/markets/elections/2028/who-will-run-for-the-democratic-presidential-nomination-in-2028/) - [Who will run for the 2028 Republican presidential nomination?](/markets/elections/2028/who-will-run-for-the-2028-republican-presidential-nomination/) - [Texas Republican Attorney General nominee?](/markets/elections/primaries/texas-republican-attorney-general-nominee/) ## Historical Resolutions No historical resolution data available for this series. ## Disclaimer This content is for informational and educational purposes only and does not constitute financial, investment, legal, or trading advice.
