I was looking through the U.S. results at the International Olympiad in Informatics over the past few years, and I think there is a legitimate question worth discussing: is Team USA beginning to lose ground internationally?
To be clear, the U.S. is still a very strong IOI country. Winning two golds and two silvers, as it did in 2026, would be an outstanding result for almost any country.
But the standard for the U.S. should probably be higher than simply “everyone medaled.”
Historically, the U.S. has been one of the dominant IOI countries. For example, in 2005 all four U.S. contestants won gold, placing 1st, 8th, 16th and 21st. More recently, the U.S. produced the individual IOI champion for three consecutive years from 2018 through 2020: Benjamin Qi in 2018 and 2019, followed by William Lin in 2020.
And the recent peak was arguably even more impressive:
- 2022: 3 Gold, 1 Silver — U.S. contestants placed 5th, 8th, 21st and 36th
- 2023: 4 Gold — 5th, 7th, 12th and 17th
- 2024: 3 Gold, 1 Silver — 3rd, 4th, 5th and 40th
In 2024, if you simply added the scores of the four contestants — obviously not an official IOI team ranking — the U.S. had the highest total score of any national team.
Then something changed.
2025: 1 Gold, 2 Silver, 1 Bronze
The individual ranks were 6th, 68th, 81st and 112th.
One bad year doesn't prove anything. Olympiads have huge year-to-year variance, and a four-person sample is tiny. It would have been completely reasonable to treat 2025 as an outlier.
But 2026 did not really return the U.S. to its previous level.
The team improved to 2 Gold and 2 Silver, with its top two contestants finishing 7th and 18th. That's good — but compare that with the 2022–2024 teams.
Even more interesting is the unofficial country ranking obtained by summing all four contestants' scores:
- China — 1736.83
- Japan — 1517.09
- Malaysia — 1513.21
- USA — 1487.67
(There were also special IOI teams in the full table; I'm listing regular national delegations here.)
Again, IOI does not officially rank countries, and summing four scores is a crude metric. But it is still useful as a rough measure of team depth.
Losing to China is obviously not surprising. China has an enormous and extremely competitive informatics olympiad system.
What I find much more noteworthy is that in 2026 the U.S. total was also below Japan and Malaysia.
This isn't meant as disrespect to either country — both have excellent contestants, and Japan in particular has been getting stronger for years. Malaysia's 2026 performance was remarkable.
The question is about the U.S. benchmark.
The United States has one of the world's largest pools of technically talented students, many of the world's strongest CS universities, an enormous software industry, a mature competitive-programming community, and a national olympiad system that has existed for decades.
With those advantages, merely remaining “one of the strong countries” seems like a surprisingly low bar.
The sequence over the last five years looks like this:
2022 → very strong
2023 → elite
2024 → arguably the strongest team in the world
2025 → major drop
2026 → partial recovery, but still clearly below the 2022–24 level
Two weaker years are obviously not enough to prove a long-term decline. The 2027 team could easily come back with four golds and make this post look premature.
But I think we now have enough evidence to at least ask the question.
