# Will there be a year without polio before 2030? Before 2030 Updated: April 27, 2026 Category: Science and Technology HTML: /markets/science-and-technology/will-there-be-a-year-without-polio-before-2030/ ## Short Answer **Key takeaway.** Both the **model** and the **market** expect that there will be a year without polio before 2030, with no compelling evidence of mispricing. ## Key Claims (January 2026) **- - Security challenges consistently hinder polio vaccination in Pakistan and Afghanistan.** - Wild poliovirus detections significantly increased across Pakistan in the last year. - New cVDPV2 outbreaks continued in 15 countries despite nOPV2 use. - Polio vaccination coverage varies, with Somalia lower than Tajikistan and Iran. - GPEI targets WPV1 eradication by mid-2026 for WHO certification. ### 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** and **market** align at **4.3%**, reflecting consistent security disruptions, increased WPV1, and new cVDPV2 outbreaks. ### Who Wins and Why | Outcome | Market | Model | Why | | --- | --- | --- | --- | | Before 2030 | 4.3% | 4.3% | The market is correct in its low assessment because Grade A evidence from official GPEI reports consistently highlights persistent and major security challenges, including attacks and campaign suspensions, as ongoing obstacles to polio eradication efforts in endemic regions, validating the 4.3% debiased probability. | ## Model vs Market - Model Probability: 4.3% (Yes) - Market Probability: 4.3% (Yes) - Yes refers to: Before 2030 - Edge: +0.0pp - Expected Return: +0.0% - R-Score: 0.00 - Total Volume: $28,330.64 - 24h Volume: $40.44 - Open Interest: $14,718.26 - Expiration: January 1, 2030 ## Market Behavior & Price Dynamics This market has demonstrated a predominantly sideways trend, trading within a narrow and low-probability range. The price has fluctuated between a low of 3.5% and a high of 10.0%, indicating a consistent belief that the event is unlikely. The market opened at 6.9% and currently trades at 4.3%, showing a modest net decline over its history. The most significant price movement was a sharp drop from approximately 7.0% to 4.3% around April 27, 2026. The provided context does not contain any specific news or developments that would explain this particular shift in odds. The total traded volume of 1,702 contracts is moderate, but trading appears to be sporadic. The significant price drop in late April was accompanied by a noticeable volume spike, suggesting that the move was driven by a period of increased market activity and conviction rather than a single small trade. The price has since found a support level around the 3.5% to 4.5% area, while the 10.0% mark has acted as a firm resistance ceiling. Overall, the chart indicates a strong and stable market sentiment, with participants consistently assessing the probability of a polio-free year before 2030 as very low, never rising above 10%. ## Contract Snapshot The market resolves to YES if there is any year between 2024 and 2029 with zero reported wild cases of poliovirus 1. The outcome is verified using data from the WHO and CDC. If this condition is not met, the market resolves to NO by its closing date of January 1, 2030, at 10:00 am EST, though it may close earlier if the YES event occurs. Payout is projected 30 minutes after closing. ## Market Discussion Limited public discussion available for this market. ## Market Data | Contract | Yes Bid | Yes Ask | Last Price | Volume | Open Interest | | --- | --- | --- | --- | --- | --- | | Before 2030 | 4.3% | 10% | 4.3% | $28,330.64 | $14,718.26 | ## What security challenges hinder polio eradication in Pakistan and Afghanistan? Primary Obstacle | Security-related disruptions including attacks and campaign suspensions (GPEI reports) [[^]](https://polioeradication.org/wp-content/uploads/2025/10/GPEI-Action-Plan-2026.pdf) | Key Affected Regions | Southern Khyber Pakhtunkhwa (KP), Pakistan, and Eastern Region of Afghanistan (GPEI reports) [[^]](https://polioeradication.org/wp-content/uploads/2025/10/GPEI-Action-Plan-2026.pdf) | Nature of Disruptions | Recurrent and persistent, leading to limited access and missed children [[^]](https://polioeradication.org/wp-content/uploads/2025/09/24th-IMB-Report-20250922.pdf) | **Security disruptions consistently hinder polio vaccination in Southern KP and Eastern Afghanistan** Security disruptions consistently hinder polio vaccination in Southern KP and Eastern Afghanistan. The Global Polio Eradication Initiative (GPEI) consistently reports that security-related disruptions, including attacks on vaccinators and security personnel, alongside campaign suspensions, pose a significant and persistent barrier to polio eradication efforts. These challenges are particularly acute in the seven endemic districts of Southern Khyber Pakhtunkhwa (KP), Pakistan, and Afghanistan's Eastern Region, which includes provinces like Nangarhar, Kunar, and Nuristan. The 24th Independent Monitoring Board (IMB) Report in September 2025 specifically noted that security concerns limit access to children in parts of Southern KP, with attacks on vaccination teams often leading to campaign suspensions and reduced reach [[^]](https://polioeradication.org/wp-content/uploads/2025/09/24th-IMB-Report-20250922.pdf). Similarly, insecurity in Afghanistan's Eastern Region continues to restrict access and disrupt campaign implementation, resulting in missed children [[^]](https://polioeradication.org/wp-content/uploads/2025/09/24th-IMB-Report-20250922.pdf). GPEI documents describe these disruptions as ongoing, indicating a consistent negative trend rather than fluctuating quarterly incident counts [[^]](https://polioeradication.org/wp-content/uploads/2025/10/GPEI-Action-Plan-2026.pdf). News reports confirm ongoing security incidents, including attacks on personnel. Although GPEI documents do not detail specific quarterly statistics on the frequency of security-related disruptions, news reports corroborate their continuous occurrence. For instance, in February 2026, police personnel sustained injuries during an attack on a polio security team in Hangu, Southern KP [[^]](https://khyberchronicles.pk/police-personnel-injured-in-attack-on-polio-security-team-in-hangu-large-scale-search-operation-underway/). Throughout 2025, several security officers guarding polio teams were reportedly attacked and martyred in various parts of Khyber Pakhtunkhwa, with incidents noted in August, September, and January [[^]](https://www.geo.tv/latest/628723-another-security-officer-guarding-polio-team-gunned-down-in-kp). These events underscore the persistent militant threats and security challenges impeding eradication efforts in Pakistan, aligning with GPEI's assessment of ongoing security concerns in the region [[^]](https://thekhorasandiary.com/en/2025/01/15/pakistan-remains-global-polio-hotspot-as-militant-threats-misinformation-impede-eradication-efforts). ## How Have WPV1 Detections Changed in Pakistan's Major Cities? Pakistan WPV1 Positive Samples (Last vs. Prior 12 Months) | 56 vs 11 samples [[^]](https://epinews.emphnet.net/en/news/slider/who-emr-polio-bulletin-issue-no1434-week-12) | Quetta WPV1 Environmental Surveillance Positivity | 0% in 2024, 2025, and early 2026 [[^]](https://reliefweb.int/attachments/2c19804d-3ef5-505e-a1d3-554b637b4a1f/EMR_Polio_Bulletin_Issue_1427_Week_05-2026.pdf) | Karachi WPV1 Positive Environmental Samples (2024 vs. 2025) | Increased from 6 to 20 samples [[^]](https://reliefweb.int/attachments/2c19804d-3ef5-505e-a1d3-554b637b4a1f/EMR_Polio_Bulletin_Issue_1427_Week_05-2026.pdf) | **Wild poliovirus detections significantly increased across Pakistan in the last year** Wild poliovirus detections significantly increased across Pakistan in the last year. Environmental surveillance in Pakistan recorded a substantial rise in wild poliovirus type 1 (WPV1) detections, with 56 positive environmental samples isolated in the most recent 12-month period (approximately March 2025 to February 2026). This marks a significant increase from the 11 positive samples found in the preceding 12-month period (March 2024 to February 2025) [[^]](https://epinews.emphnet.net/en/news/slider/who-emr-polio-bulletin-issue-no1434-week-12). In contrast, Quetta consistently reported zero WPV1 positive environmental surveillance sites and samples throughout 2024, 2025, and into early 2026 [[^]](https://reliefweb.int/attachments/2c19804d-3ef5-505e-a1d3-554b637b4a1f/EMR_Polio_Bulletin_Issue_1427_Week_05-2026.pdf). Karachi and Peshawar show a clear increase in WPV1 positivity. While precise aggregated percentages of positive sites for Karachi and Peshawar over the entire 12-month periods are not fully detailed, available data indicates an increasing trend in WPV1 presence. Snapshot data from March 2025 showed Karachi with **5%** positivity (1 of 20 sites) and Peshawar with **10%** positivity (1 of 10 sites) [[^]](https://reliefweb.int/report/pakistan/pakistan-weekly-environmental-sampling-results-15-march-2025). Peshawar also reported **10%** positivity in January 2026, with one out of ten samples testing positive [[^]](https://www.thenews.pk/print/1404430-low-polio-virus-detected-in-sewage-as-only-one-case-reported-so-far-in-2026). Furthermore, both cities experienced a notable increase in annual positive WPV1 environmental samples: Karachi's detections rose from 6 in 2024 to 20 in 2025, and Peshawar's from 3 in 2024 to 14 in 2025 [[^]](https://reliefweb.int/attachments/2c19804d-3ef5-505e-a1d3-554b637b4a1f/EMR_Polio_Bulletin_Issue_1427_Week_05-2026.pdf). As of early February 2026, both cities continued to report WPV1 detections, each with 2 positive samples [[^]](https://reliefweb.int/node/4197845). ## Are New cVDPV2 Outbreaks Still Occurring Despite nOPV2 Use? Countries with New cVDPV2 | 15 (October 2025 - March 2026) [[^]](https://www.who.int/news/item/04-03-2026-statement-of-the-forty-fourth-meeting-of-the-polio-ihr-emergency-committee) | Reporting Period | October 2025 - March 2026 [[^]](https://www.who.int/news/item/04-03-2026-statement-of-the-forty-fourth-meeting-of-the-polio-ihr-emergency-committee) | nOPV2 Reach (Ethiopia Example) | Over 24 million children in one round [[^]](https://www.afro.who.int/countries/ethiopia/news/over-24-million-children-reached-recent-integrated-nopv2-campaign) | **New outbreaks of circulating vaccine-derived poliovirus type 2 (cVDPV2) continued across 15 countries** New outbreaks of circulating vaccine-derived poliovirus type 2 (cVDPV2) continued across 15 countries. Between October 2025 and March 2026, new emergences or expansions of cVDPV2 were reported in Chad, Mali, Nigeria, Niger, Somalia, Afghanistan, Democratic Republic of the Congo (DRC), Burundi, Central African Republic, Guinea, Mauritania, Mozambique, Pakistan, South Sudan, and Yemen [[^]](https://www.who.int/news/item/04-03-2026-statement-of-the-forty-fourth-meeting-of-the-polio-ihr-emergency-committee). These detections highlight an ongoing challenge, particularly within the African region, with Burundi and DRC specifically reporting cVDPV2 detections in October 2025 [[^]](https://polioeradication.org/news/gpei-statement-on-cvdpv2-detections-in-burundi-and-democratic-republic-of-the-congo/). These outbreaks occurred amidst widespread global deployment of the novel Oral Polio Vaccine type 2 (nOPV2), which has been extensively utilized in response efforts, such as campaigns in Ethiopia reaching over 24 million children in a single round [[^]](https://www.who.int/news/item/04-03-2026-statement-of-the-forty-fourth-meeting-of-the-polio-ihr-emergency-committee). Despite nOPV2's widespread use, new cVDPV2 emergences remain a concern. The Global Polio Eradication Initiative (GPEI) recognizes that nOPV2's broad application is having a significant impact on outbreak response and mitigation [[^]](https://www.who.int/news/item/04-03-2026-statement-of-the-forty-fourth-meeting-of-the-polio-ihr-emergency-committee). However, the concurrent detection of multiple new cVDPV2 emergences and expansions since October 2025 suggests that while nOPV2 is crucial for controlling outbreaks, it has not yet fully prevented new emergences in all contexts [[^]](https://www.who.int/news/item/04-03-2026-statement-of-the-forty-fourth-meeting-of-the-polio-ihr-emergency-committee). The Polio IHR Emergency Committee's continued expression of concern over rising cVDPV2 cases underscores the critical need for sustained vigilance and vaccination efforts to address the persistent threat of poliovirus [[^]](https://www.who.int/news/item/04-03-2026-statement-of-the-forty-fourth-meeting-of-the-polio-ihr-emergency-committee). ## What are Polio Vaccination Rates in Tajikistan, Iran, and Somalia? Tajikistan IPV Coverage (2022) | 99% IPV1, 98% IPV2 (children by 12 months) [[^]](https://immunizationdata.who.int/dashboard/regions/european-region/TJK) | Iran IPV Coverage (2022) | 99% IPV1, 99% IPV2 (children by 12 months) [[^]](https://data.unicef.org/topic/child-health/immunization/) | Somalia IPV Coverage (2022) | 53% IPV1, 22% IPV2 (children) [[^]](https://data.unicef.org/topic/child-health/immunization/) | **Tajikistan and Iran demonstrate high inactivated polio vaccine coverage** Tajikistan and Iran demonstrate high inactivated polio vaccine coverage. In 2022, Tajikistan reported an estimated **99%** of children by 12 months receiving their first IPV dose (IPV1) and **98%** receiving their second (IPV2) [[^]](https://immunizationdata.who.int/dashboard/regions/european-region/TJK). Similarly, the Islamic Republic of Iran achieved **99%** coverage for both IPV1 and IPV2 among children by 12 months in the same year [[^]](https://data.unicef.org/topic/child-health/immunization/). Furthermore, a study on Afghan refugee children aged 12–23 months in Iran indicated that **92.1%** had received at least one IPV dose, with **71.3%** being fully vaccinated overall [[^]](https://www.emro.who.int/emhj-volume-31-2025/volume-31-issue-8/immunisation-coverage-among-refugee-afghan-children-in-islamic-republic-of-iran.html). Somalia faces substantial challenges in achieving adequate polio vaccination rates. In 2022, only **53%** of children in Somalia had received one dose of IPV (IPV1), and a significantly lower **22%** had received two doses (IPV2) [[^]](https://data.unicef.org/topic/child-health/immunization/). While a 2023 survey showed national fractional IPV (fIPV) coverage at **73.1%** among children under five, regional disparities were evident, such as **76.5%** in Puntland and **69.4%** in South-Central regions [[^]](https://bmcglobalpublichealth.biomedcentral.com/articles/10.1186/s44263-024-00044-7). This reflects a broader concern about under-immunization, as only **38%** of children aged 12–23 months had received all basic vaccinations [[^]](https://link.springer.com/article/10.1007/s44197-025-00395-w?error=cookies_not_supported&code=4da8e502-007a-447e-a122-b25c0a560c2e). The persistent wild poliovirus transmission in neighboring Pakistan and Afghanistan intensifies the need for improved vaccination efforts in these interconnected, high-risk areas [[^]](https://healthpolicy-watch.news/wild-poliovirus-transmission-persists-in-afghanistan-and-pakistan/). ## How Does Polio Eradication Align with WHO Certification Goals? GPEI's Projected Last WPV1 Case | By the end of 2024 [[^]](https://polioeradication.org/wp-content/uploads/2024/11/GPEI-Strategy-extension-20241113.pdf) | WHO Certification Requirement | Three consecutive years with zero detected WPV1 cases [[^]](https://iris.who.int/server/api/core/bitstreams/49602e7f-8824-4450-bb10-a1636d14c800/content) | Practical Deadline for Last WPV1 Case (to certify before 2030) | Late 2026 [[^]](https://polioeradication.org/wp-content/uploads/2025/10/GPEI-Action-Plan-2026.pdf) | **The Global Polio Eradication Initiative (GPEI) projects the last WPV1 case by late 2024** The Global Polio Eradication Initiative (GPEI) projects the last WPV1 case by late 2024. In its "Strategy Extension 2024-2026," the GPEI targets the interruption of all wild poliovirus type 1 (WPV1) transmission by the end of 2024 [[^]](https://polioeradication.org/wp-content/uploads/2024/11/GPEI-Strategy-extension-20241113.pdf). This strategic update also aims to achieve the eradication of all polioviruses, including circulating vaccine-derived polioviruses (cVDPV), by 2026 [[^]](https://polioeradication.org/wp-content/uploads/2024/11/GPEI-Strategy-extension-20241113.pdf). WHO mandates three consecutive years with zero WPV1 for certification. Global polio eradication certification, as required by the World Health Organization (WHO), necessitates a three-year period without any detected WPV1 cases following the last reported instance [[^]](https://iris.who.int/server/api/core/bitstreams/49602e7f-8824-4450-bb10-a1636d14c800/content). To achieve certification before the end of 2029 or early 2030, the final WPV1 case must be identified no later than late 2026. This timeline would enable three full calendar years (2027, 2028, and 2029) to pass without WPV1 cases, thus satisfying the WHO's essential requirement for certification by the close of 2029 [[^]](https://iris.who.int/server/api/core/bitstreams/49602e7f-8824-4450-bb10-a1636d14c800/content). GPEI's 2024 target provides a significant buffer for certification. The GPEI's projected date for the last WPV1 case by the end of 2024 aligns favorably with the practical deadline needed for pre-2030 certification. Should the GPEI successfully meet this target, the last WPV1 case would occur approximately two years ahead of the late-2026 cutoff required for certification before 2030. This provides a substantial buffer for the three-year disease-free surveillance period mandated by the WHO [[^]](https://polioeradication.org/wp-content/uploads/2024/11/GPEI-Strategy-extension-20241113.pdf). ## What Could Change the Odds **Key takeaway.** Catalyst analysis unavailable. ## Key Dates & Catalysts - **Expiration:** January 01, 2030 - **Closes:** January 01, 2030 ## Decision-Flipping Events - Catalyst analysis unavailable. ## Related Research Reports - [AI capability growth before July?](/markets/science-and-technology/ai/ai-capability-growth-before-july/) - [Will the U.S. confirm that aliens exist before 2027?](/markets/science-and-technology/trump/will-the-u-s-confirm-that-aliens-exist-before-2027/) - [What will the average number of measles cases be during Trump's term?](/markets/science-and-technology/diseases/what-will-the-average-number-of-measles-cases-be-during-trump-s-term/) - [NVIDIA B200 Compute Price Up or Down by Apr 10, 2026?](/markets/science-and-technology/energy/nvidia-b200-compute-price-up-or-down-by-apr-10-2026/) ## 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.
