XPRIZE Healthspan measurement and trials

XPRIZE Healthspan organises a competition around improvements in muscle, cognitive and immune function. Twenty teams entered the finals in August 2026. Its contribution is a shared trial and measurement framework; finalist selection is not evidence that a competing intervention has achieved the prize's target.

XPRIZE Healthspan asks competing teams to demonstrate functional improvement in people. Its target is expressed in years of expected age-associated decline, using reference populations and specified tests.

The competition is research infrastructure. It contains multiple interventions, sponsors and trials. Listing the competition as a single successful therapy would conceal the different approaches and the evidence required for each.

XPRIZE announced 20 finalist teams on 11 August 2026, with ten receiving $1 million milestone awards. An older page still displays the earlier 40-team semifinalist group.

SchematicThe domains assessed by the framework
  • Muscle functionStandard functional assessments.
  • Cognitive functionDefined computerised testing.
  • Immune functionSpecified assessments under the prize rules.

These are parallel assessment domains. A prize threshold does not measure extra years of life. Sources for this account.

The mechanism

The framework examines muscle, cognitive and immune function. Teams compare their intervention with a control condition, then submit results for assessment under shared rules.

The published guidelines translate a functional change into an equivalent period of expected decline in a reference population. The calculation defines a prize threshold. It does not measure the number of extra years a participant will live.

The finals rules specify standard assessments, including a six-minute walk and lower-body power tests, with computerised cognitive testing. They also separate exploratory biomarker analyses from the principal judging outcomes.

Common measurements can help readers compare trials, but they do not make the interventions interchangeable. A cell therapy and a behavioural programme can carry very different mechanisms, burdens and safety questions even when participants complete the same tests.

Human evidence

The finalists advance into a clinical-testing framework. Selection reflects the organisers' assessment of rationale, readiness and other criteria. It is not a pooled human efficacy result for twenty programmes.

The central data coordinating centre is associated with the University of Utah, with shared laboratory and sample resources coordinated through UC San Diego. These arrangements create a route to more consistent collection and analysis across sites.

Each team's intervention needs its own registry record, protocol, participant characteristics and results. Selection as a finalist does not establish the outcome of that team's trial.

Studies and experimental evidence

XPRIZE Healthspan finals framework

Comparison
Placebo, control or standard-of-care condition, depending on intervention
Duration
Intervention and assessment within approximately one year
Outcome
Functional responder thresholds across muscle, cognition and immunity

No pooled finals efficacy result verified as of 4 October 2026

Prize participation and awards cannot establish efficacy; interventions and populations differ

Funding and interests: Hevolution, SOLVE FSHD and other competition supporters; team funding differs

Development history

First milestone awards announced

Forty Healthspan teams were selected as milestone winners from the earlier qualifying cohort.

Unresolved questions

  • Which finalist trials have registered complete protocols and begun recruitment?
  • How much change exceeds control-group improvement on the shared tests?
  • Do improvements persist after the intervention period?
  • How sensitive are responder classifications to the chosen reference population?
  • Will complete datasets and negative results become publicly accessible?
  • What does each intervention cost and require when moved beyond its research setting?

The competition is in its finals stage and states that it culminates in 2030. Individual trial registrations, participant follow-up and released results will show what each intervention achieves.
