WADA 2026 Annual Report: Sample Testing Rises, But the Growth Curve Has Flattened

At 5:12 in the morning, at a training pool with no spectators, I heard three sounds stacking on top of each other: the crack of water as the last swimmer entered the lane, the squeak of the sample collector's rubber shoes along the technical corridor, and the zip of a cold bag holding test tubes. Nobody applauded. No scoreboard was lit. There was only a receipt form and a ballpoint pen laid neatly on the edge of a plastic chair.

Those three sounds never appear in any results bulletin. They belong to another layer of sport, the layer that runs behind the race and is never projected onto a big screen. WADA's 2026 annual report records that layer in numbers. As for me, sitting in that technical corridor, what I remember most is the silence before a test tube gets its label. In the emptiness, I hear the breathing of the contest more clearly. This year, that breathing sounds different.

Context: an inventory of sport's submerged half

WADA's annual report is not a results sheet. It is an inventory of a governance system: how many samples were collected, how many returned adverse findings, how many countries were flagged as non-compliant, how much money came in, how much went out, and when the next code takes effect.

That system stacks in tiers. WADA sets the standard. The International Olympic Committee and national governments pay. National anti-doping organizations run sample collection. International federations, with World Aquatics for swimming, are responsible for applying the standard within their sport. When one tier falls out of rhythm, every other tier hears it.

Some terms to hold before reading the numbers. AAF is an Adverse Analytical Finding, the technical term for a positive sample. Out-of-competition testing means no-notice collection outside the competition window. Non-conformity is a finding that an organization or government fails to meet the Code. The World Anti-Doping Code is the founding document harmonizing anti-doping rules worldwide. The Athlete Biological Passport is a long-term monitoring tool tracking physiological markers, running alongside direct sample collection.

One timing detail is worth noting. The document is called the 2026 report, yet the sample series it publishes is tied to 2026 and 2026, while the income line is marked 2026. That is a conventional publication lag, and it may also be loose labeling. Anyone reading the numbers needs to know what is being compared with what before drawing conclusions.

For swimming, there is an extra layer of context. Swimming has a dense testing program: many events, many distances, many young athletes not yet in the routinely monitored pool. A standard-setting system tightening money and time will reach swimming earlier than many sports, not at the starting blocks, but in the technical corridor.

Sample volume and a flattening gradient

Total samples in 2026 were 288,865. In 2026, 297,965. The gap is roughly 9,100 samples, equivalent to a 3.2 percent increase.

Step back one more year and the picture changes. From 2026 to 2026, total samples rose 12.5 percent. From 2026 to 2026, growth was only 3.2 percent. The growth curve has bent sharply downward: most of the momentum was front-loaded, then cooled noticeably. The growth rate fell nearly fourfold in a single step.

For a system measured by coverage capacity, slope matters more than total. A decelerating line usually signals that resources have hit a ceiling, not that an expansion is underway. In other words, the system is still growing, but growing far more slowly than it was two years ago.

The data also has a long axis. The report's chart runs from 2026 to 2026. That series is long enough to rule out temporary swings, and long enough to show that seven years produced no step change in scale. This is a system that grows in steps, not in a vertical line.

Based on my experience covering international swimming meets, I noticed a detail rarely mentioned in news copy. The 9,100 additional samples in one year sounds large, but spread across hundreds of national federations and dozens of sports, it becomes a small share per unit. In the places where I have stood, the increase is not visible to the eye; it is only perceptible as sample collectors appearing more often within a single training session.

Detection rate and the base-rate trap

The AAF rate over the last three years was 0.77 percent, 0.80 percent and 0.78 percent. The swing sits within a 0.03 percentage-point band. This is the most stable point in the entire report, and the easiest to misread.

When sample volume rises while the detection rate holds, there are two explanations. One is that the true violation rate in the athlete population is unchanged. The other is that testing has expanded into a group with a positivity level similar to the old group. The available data cannot separate these. Both produce the same figure on the page.

What cannot be inferred is that the system is cleaner, or that it is less effective. A stable rate says nothing about the trend in violations. It says only that the numerator and denominator are growing in step. Anyone reading 0.78 percent as a safety guarantee is turning a flat number into a promise.

For swimming, caution is required in any argument about whether the sport is clean. The report does not break numbers down by sport. Any claim that swimming has a low positivity rate is borrowing a global figure to describe one sport. That is an inference the data does not support, however plausible it sounds.

Compliance audits: improvement on a thin sample

The report records average non-conformities falling from 25.5 to 20. That sounds like clear progress. But the figure is drawn from nine audits.

Nine audits is a thin sample. With that size, a few organizations changing behavior is enough to move the average. The conclusion that compliance is improving is not solid enough to be a trend; it is only a signal. In analytical work, I generally ask about sample size before asking about results. Here, the sample size answers before the results do.

Kazan taught me that speed knows how to dance. Here, what dances is the average: shifting a few audited entities can produce a flattering figure with nothing changed in operational reality. A tidy table does not always reflect a tidy system.

Sample collection is the fracture point

This is the report's most concrete finding. Non-conformities related to sample collection account for 45 percent of all findings, up 11 percent year on year, with 23 percent of them rated critical.

Read the direction of these two figures carefully. On one hand, average total non-conformities fell. On the other, the collection-related group rose. The rising group sits exactly at the stage that determines the quality of the input data. If samples are collected outside procedure, every conclusion downstream carries systematic error, and systematic error cannot be offset by collecting more samples.

For swimming, collection carries particular complexity. Swimmers spend many hours a day in the water. Out-of-competition testing requires reaching the right person, at the right time, with the right storage procedure. A country with few anti-doping staff will struggle most at exactly this stage, not at the laboratory analysis stage.

In Southeast Asia, where I grew up and have followed sport for years, the gap between a swimming federation with enough staff and one that outsources collection is a gap in fairness. The report names no country, but the structure of the errors shows where allocation problems exist within the system.

Money: the report's most strained point

The financial section is where the report leaves an administrative tone and touches politics. WADA records a shortfall of 8.3 million US dollars against plan. Two major contributors are in arrears: the United States at 3.8 million dollars and Russia at 3.9 million dollars. At the same time, the agency reports a net surplus of 1.2 million dollars.

The coexistence of a large shortfall and a small net surplus implies two things. Either spending was tightened hard, or some expenditures were deferred. Both point to the same short-term consequence: investment in sample collection may be compressed while cash flow stabilizes.

When a standard-setting body depends on the goodwill of member states for its budget, enforcement authority does not rest entirely with that body. Money is the material condition of fairness. When cash flow wobbles, the question of who enforces the enforcer returns, and it returns exactly when the system needs stability most.

For swimming, the impact travels indirectly but is real. Swimming's testing program demands steady resources because athlete numbers are large and testing windows are many. Developing swimming federations with thin resources depend on support from the shared system. If shared resources tighten, the first affected are those with the least voice, and those often have the youngest athletes.

A strategic pivot: from sampling to investigations

The report describes a clear shift: the system is moving from traditional testing toward investigations and prevention. The accompanying figures include more than 250 investigative operations, 88 laboratories dismantled, and more than 90 tonnes of materials seized.

This is a weighty change. Testing is a probability strategy: more samples, more chances of detection. Investigation is a targeting strategy: fewer actions, aimed better. The two do not fully replace each other; they share one budget. Every dollar spent on investigation is a dollar not spent on a test tube.

If money tightens and priority tilts toward investigations, the logical consequence is that samples per sport may fall. For a sport with high testing density like swimming, this is worth watching in the coming cycle. A smarter system may not be one that collects more samples, but it must prove that with results, and the current report offers no such comparison.

Athlete consultation: breadth yes, depth unmeasured

WADA and the Athlete Council ran an athlete-centered consultation with more than 600 athletes and commissions from over 60 countries and over 70 sports. The breadth is real, and it shows athlete representative bodies maturing as a force in sports governance.

But the report does not say whether athlete input changed the substance of the Code. No indicator measures influence. This is an evidence gap, not a statement about effectiveness. In years of writing about sport, I have learned that a broad process is not necessarily a weighty one, and the difference between the two only shows up when a hard decision is made.

The 2027 Code: a fixed milestone

The 2027 edition of the World Anti-Doping Code and Standards was adopted in Busan, South Korea, and takes effect on January 1, 2027.

This is the highest planning-value information in the entire report. A fixed, published date lets every signatory prepare. At the same time, the period from now to that date is a compliance-gap window: behavior under the old standard can persist while the new one has not taken effect. Such transition periods tend to create grey zones, and grey zones punish weak organizations hardest.

For swimming, a January 1, 2027 date means the next two seasons run under the old standard. Any change to collection procedure, filing requirements, or athlete whereabouts obligations takes effect only after that date. Federations have time to prepare, but preparation time is only valuable where there are people to use it.

The contrarian angle: the headline says up, the data says slowing

One thing should be said plainly: the report is communicated with a message of expanded testing, while the data show expansion slowing from 12.5 percent to 3.2 percent. That is a gap between headline and body, and it is not small.

The message of a win for WADA in the report should also be read as the author's framing, not a finding. The real picture is mixed: audits improved, finances are strained, sample collection worsened. Three currents run in different directions inside one document.

A second counterintuitive point: a system reporting a nearly flat detection rate for three years could be working better, or could be stalling. Both states produce the same number. No secondary indicator in the report distinguishes them, which is why the 0.78 percent figure carries the least information relative to its precise appearance.

A third counterintuitive point concerns power. The global standard-setter depends on contributions that major states themselves can delay. A system with unstable resources has unstable universality. If arrears become routine, the funding model erodes structurally, not just numerically.

A fourth point, perhaps the least discussed: a system pivoting to investigations may look stronger in communications while being harder to verify with public statistics. Sample counts are numbers anyone can tally. Successful investigations are not. Moving to a harder-to-measure strategy is a bet on trust.

Takeaway

Silence is not short of language; it owns a language of its own. This report speaks in that language: slowly rising numbers, a flat rate, a fracturing collection stage, and a milestone already fixed for 2027.

The task for swimming is not to argue whether the sport is clean. The task is to track three specific indicators in the next reporting cycle: whether sample growth has bottomed out, whether the detection rate breaks above 0.85 percent, and whether the collection-stage error share keeps exceeding 45 percent.

Each of those indicators, when it moves, will precede a change in the technical corridor, where there are no spectators, but where the fairness of swimming is decided one test tube at a time. People tend to remember the speed of a stroke more than the name of the person who labels that swimmer's sample. Yet both belong to the same competition, differing only in that one is broadcast and the other sits in a file nobody opens.

When the next season begins, I will again stand in some technical corridor, counting how many times the door opens, and noting the breathing of the contest. The numbers in the report will only mean something when set against what is heard at the closest distance to the water.
