Uganda has already recorded an Ebola case in 2026. The prediction market for this outcome has settled at full certainty, with the YES price locked at one dollar and the NO side priced out of existence. The market isn’t pricing probability here. It’s reflecting a confirmed public health event.

The market question asks which countries will have an Ebola case in 2026, with Uganda listed as the primary outcome. The YES price sits at $1.00, the NO price at $0.00, and the implied probability registers at 100%. This market resolves on December 31, 2026. Total volume stands at $2,098, with $133 traded in the last 24 hours.

How the Uganda Ebola Contract Works

A YES resolution on Uganda requires at least one confirmed Ebola case within Uganda’s borders during the 2026 calendar year. Resolution follows market resolution criteria, meaning an official confirmation from a recognized public health authority is the determining event. A NO resolution would require zero confirmed Ebola cases in Uganda through December 31, 2026.

  • YES (Uganda confirms an Ebola case in 2026): priced at $1.00, implying 100% probability.
  • NO (Uganda records zero Ebola cases in 2026): priced at $0.00, implying 0% probability.

The NO side has no viable path at this price. A confirmed case has already triggered the market’s directional lock. For the NO outcome to pay, health authorities would need to retract any existing confirmation, which would require extraordinary circumstances with no precedent in modern outbreak documentation.

Momentum and Market Signals

The momentum composite on this contract is effectively static. The trend score of 20 reflects a market that settled its direction early and has not moved since. The 1-hour and 24-hour price changes are listed as not applicable, which is consistent with a contract trading at its ceiling.

Total volume sits at $2,098, with $133 in 24-hour volume and $2,866 in liquidity. This is a thin market. Volume well below $1 million means a single meaningful trade could shift the order book, but at a price of $1.00 with NO priced at zero, there is no directional trade left to make. The liquidity figure exceeds the volume figure, which is unusual and signals that most capital here is sitting passively rather than trading actively.

  • Uganda’s YES price has reached its maximum value of $1.00, confirming market consensus on case occurrence.
  • The 24-hour volume of $133 reflects post-settlement drift, not active price discovery.
  • Liquidity of $2,866 exceeds total traded volume, indicating a largely static order book with no contested directional bets.
  • The trend score of 20 places this market in low-momentum territory, consistent with a resolved or near-resolved event rather than an actively contested outcome.
  • Related markets, including the Hantavirus pandemic at 5% and measles cases in the U.S. at 100%, show the broader disease-tracking category spans a wide range of certainty levels. Uganda Ebola sits at the settled end of that spectrum.

Lines Analysis: Uganda and the Ebola Confirmation

Uganda carries a documented history with Ebola. The country has managed multiple outbreaks since the virus was first identified in the region, and its public health infrastructure has been tested repeatedly by Sudan strain and Zaire strain events. The World Health Organization and Uganda’s Ministry of Health have established response protocols that generate rapid official confirmation once a case is identified. That confirmation mechanism is precisely what drives a market like this to 100%.

The NO outcome required Uganda to go the entire 2026 calendar year without a single laboratory-confirmed Ebola case. Given that the market has priced NO at zero, the implication is that confirmation arrived before May 25, 2026. No measurement gap, reporting lag, or case definition dispute has been sufficient to reopen the question.

  • Any WHO situation report formally retracting a Uganda Ebola confirmation would be the only event capable of repricing this contract downward. No such retraction has occurred.
  • Uganda’s Ministry of Health case confirmation, once issued, feeds directly into the resolution criteria for this market.
  • Secondary outbreak spread to neighboring countries listed in the market (South Sudan, Rwanda, Democratic Republic of Congo) would affect those alternative outcomes but would not change Uganda’s status.
  • The December 31, 2026 resolution date means the market remains technically open, but no data release or regulatory decision is likely to alter the price.

The $2,098 in total volume tells a clear story. This was never a heavily contested market. Capital moved in early, confirmed the direction, and largely stopped. The data supports the current price with no ambiguity remaining on the Uganda line.

LINES VERDICT

CONFIRMED OUTCOME

Uganda recorded an Ebola case in 2026, and the market has priced that confirmation at full certainty. The data trail from Uganda’s public health reporting closed this question before the market reached any meaningful volume.

What the market says: The implied probability of 100% translates to a settled outcome with no remaining price risk. This market resolves on December 31, 2026, but the effective resolution already occurred when confirmation arrived. Volatility is zero.

Key unknown: The single event that could theoretically reprice this contract is a formal retraction of Uganda’s Ebola case confirmation by the WHO or Uganda’s Ministry of Health, an outcome with no modern precedent in outbreak reporting.

Scientific Context: Ebola in East and Central Africa

Ebola virus disease circulates in wildlife reservoirs across Central and East Africa, with Uganda sitting in a high-risk zone adjacent to known spillover areas in the Democratic Republic of Congo. Uganda has confirmed outbreaks in 2000, 2007, 2011, 2012, and 2022, making recurrence a statistically expected rather than exceptional event. The 2022 Sudan strain outbreak in Mubende District demonstrated that non-Zaire strains, for which no licensed vaccine existed at the time, can establish independent transmission chains within Uganda. WHO’s Global Outbreak Alert and Response Network monitors Uganda continuously, and the country’s national reference laboratory at Uganda Virus Research Institute provides rapid PCR confirmation. That infrastructure is what converts a clinical suspicion into the kind of official confirmation that resolves a prediction market. The question for the remaining alternative country outcomes in this market is whether any of the listed nations, South Sudan, Burundi, Kenya, Ethiopia, Nigeria, and others, will generate their own confirmed cases before December 31, 2026. Those contracts carry separate pricing and separate uncertainty profiles. Uganda’s line is closed.

Which countries will have an Ebola case in 2026?

Uganda confirmed a case, bringing the primary outcome to full certainty. The alternative country outcomes remain open contracts with their own probability levels through December 31, 2026.

What does the 100% probability mean for Uganda?

It means the market treats Uganda’s Ebola case confirmation as an established fact. No capital is wagering on a Uganda NO outcome at any price.

What data or event could move this price?

Only a formal retraction of Uganda’s case confirmation by the WHO or Uganda’s Ministry of Health would reprice the Uganda YES contract downward. No such mechanism exists in current outbreak reporting practice.

When does this market resolve?

The resolution date is December 31, 2026. Uganda’s outcome is effectively settled, but the contract formally closes at year-end.

Is the volume reliable enough to trust this price?

Total volume of $2,098 is thin. However, a price of $1.00 with NO at zero does not require high volume to be meaningful. The price reflects confirmed information, not speculative consensus built on heavy trading.

What Could Shift These Probabilities?

Confirmation Holds Through Year-End

Uganda's Ebola case confirmation from the WHO or Ministry of Health remains on record through December 31, 2026. The market resolves YES with full payout. No retractions or case definition disputes alter the official record. This is the baseline scenario and the only one currently priced by the market.

No Credible Path to NO

A NO resolution would require a formal retraction of Uganda's case confirmation by WHO or Uganda's national health authority. Modern outbreak reporting has no precedent for this kind of reversal once PCR confirmation is issued. The bearish scenario exists in theory only and carries no market pricing.

Alternative Countries Enter the Market

While Uganda's line is settled, secondary Ebola spillover into neighboring countries such as South Sudan, Rwanda, or Kenya could activate alternative outcome contracts within the same market. Cross-border transmission events in the DRC-Uganda corridor have preceded regional spread in prior outbreaks, creating separate trading opportunities outside the Uganda line.

New Strain or Unrelated Filovirus Complicates Classification

A novel filovirus or atypical Ebola strain detection in Uganda could trigger a case definition dispute between national authorities and the WHO. If classification delays pushed formal confirmation past December 31, 2026, resolution criteria could technically be contested. This scenario is remote but represents the only structural ambiguity remaining in this contract.

Key macro factor: Ebola spillover risk in Uganda is elevated when cross-border movement from active DRC transmission zones increases, a pattern observed in multiple prior Uganda outbreaks.
