Science Fair Prize Money: What Top Student Scientists Win

Science fair prize money at the top of the U.S. circuit is far bigger than most people picture. The single largest individual prize goes to the winner of the Regeneron Science Talent Search, and in 2026 it was $250,000. According to Society for Science, Connor Hill, 17, of State College, Pennsylvania, took that top award for cataloging the mathematical shapes known as noble polyhedra.

He was not the only one paid. Society for Science reports that the 40 Regeneron STS finalists shared more than $1.8 million in 2026, with every finalist guaranteed at least $25,000. Two months later, at the Regeneron International Science and Engineering Fair in Phoenix, more than 1,700 students split over $7 million.

So when you hear “science fair,” picture something closer to a scholarship tournament than a gym full of trifold posters. Below are the current, verified figures, where the money comes from, and how a student actually gets to the stage where those checks are handed out.

The Biggest Science Fair Prize Money in the U.S. Right Now

Two competitions dominate. The Regeneron Science Talent Search (STS) is for U.S. high school seniors and pays the largest single prize. The Regeneron International Science and Engineering Fair (ISEF) is the world’s largest precollege science competition and pays out the largest total pool.

Per Society for Science, STS awards run on a tiered ladder: 300 scholars receive $2,000 each, and their schools each receive $2,000 as well. Forty of those scholars advance to finalist status and receive a minimum of $25,000. The top 10 finishers receive between $40,000 and $250,000.

At ISEF 2026, Society for Science and Regeneron announced that Hikaru Kuribayashi, 17, of Sapporo, Japan, won the $100,000 George D. Yancopoulos Innovator Award for a simulation program that models complex folding, including origami. The award is named for Regeneron’s co-founder and chief scientific officer.

A Quick Table of the Current Science Fair Prize Money

Here are the headline figures from the two 2026 competitions, plus the leading middle school event, as published by Society for Science and Regeneron.

How Regeneron ISEF Spreads $7 Million Around

ISEF works differently from STS. Instead of one deep ladder, it spreads awards across 22 judged categories. Society for Science reported that the 76th annual fair ran May 9–15, 2026, in Phoenix, drawing more than 1,700 finalists from over 67 countries, regions and territories, who received more than $7 million in total.

The very top prizes are selected from among the first-award winners in those categories. Beyond Kuribayashi’s $100,000, Society for Science named two Regeneron Young Scientist Award winners at $75,000 each: Lakshmi Agrawal, 18, of Bellevue, Washington, for a sponge that removes salmon-killing pollutants from water, and Nikola Veselinov, 17, of Sofia, Bulgaria, for a new mathematical theorem.

Two $50,000 awards follow — the Gordon E. Moore Award for Positive Outcomes for Future Generations and the F. Thomson Leighton and Bonnie Berger Family Prize for STEM Excellence — along with several $10,000 awards. Society for Science says the number of awards in each category is proportional to how many projects were entered there.

The Odds Behind Science Fair Prize Money

The science fair prize money is real, but so is the funnel. Regeneron’s 2026 announcement noted that the 40 STS finalists were chosen from 300 scholars, who in turn came out of more than 2,600 total entrants. That puts a finalist slot — and the guaranteed $25,000 — at roughly one in 65 entrants.

ISEF is narrower at the door and wider at the payout. Society for Science says finalists come through a network of nearly 400 affiliated fairs across more than 80 countries, regions and territories, with more than 175,000 students competing at local, regional and national levels for roughly 1,800 invitations.

Here is the part that surprises people: because ISEF hands awards to a large share of its finalists across 22 categories, simply reaching Phoenix gives a student a meaningful shot at some science fair prize money. Reaching Phoenix is the hard part, not placing once you are there.

Middle Schoolers Compete for Science Fair Prize Money Too

The prize ladder starts before high school. Society for Science runs the Thermo Fisher Scientific Junior Innovators Challenge, described as the nation’s premier middle school STEM competition. Its top honor is the $25,000 Thermo Fisher Scientific ASCEND Award.

In 2025, that award went to Miles Wu, 14, of New York City. Society for Science reported that he tested 54 variations of the Miura-ori origami fold and found designs that supported more than 9,000 times their own weight, with an eye toward lightweight disaster-relief shelters.

The scale is smaller: 30 finalists from 10 states and Puerto Rico competed in Washington, D.C., for more than $100,000 in total awards. Still, a 14-year-old winning $25,000 for folding paper in a rigorous way is a fair snapshot of how this system works.

Where the Science Fair Prize Money Comes From

Corporate sponsors, mostly. The Science Talent Search began in 1942 as the Westinghouse Science Talent Search, a partnership between Science Service — now Society for Science — and Westinghouse executive G. Edward Pendray. Intel took over as title sponsor in 1998, and Regeneron Pharmaceuticals was announced as the new sponsor in May 2016.

That funding is not year-to-year. Regeneron announced that it is extending its STS title sponsorship through 2036, pledging $150 million to the program. The 2026 competition marked both the 85th anniversary of the Science Talent Search and Regeneron’s 10th year as title sponsor.

Society for Science lists the combined STS award pool at $3.1 million per year across scholars and finalists. So the science fair prize money you see on stage is one slice of a much larger, multi-decade commitment.

What Winners Should Know About Taxes and Paperwork

Large awards come with tax questions, and the rules are public. IRS Topic no. 421 explains that scholarships and fellowship grants can be tax-free if you are a candidate for a degree at an eligible educational institution and the money goes toward tuition, required fees, books, supplies and equipment.

The same IRS guidance says amounts used for incidental expenses — room and board, travel, optional equipment — must be included in gross income, as must amounts that are payment for teaching, research or other required services. IRS Publication 970, Tax Benefits for Education, covers the details.

How any specific award is treated depends on how it is structured and on the winner’s own situation. That is a question for the IRS directly or a qualified tax professional, not a rule of thumb. Nothing here is tax advice.

Surprising Facts Worth Knowing

Society for Science reports that Science Talent Search alumni have collectively gone on to receive 13 Nobel Prizes, 20 MacArthur Fellowships and 11 National Medals of Science. The first competition, in 1942, was won by Paul Teschan of Shorewood, Wisconsin, and Marina Meyers of Farmingdale, New York.

The winning projects also tend to be stranger than you would guess. The 2026 STS top three included Iris Shen, 17, of The Woodlands, Texas, who studied whether a marine clam with a naturally occurring blood cancer could help test human leukemia drugs. Edward Kang rounded out the top three.

And the science fair prize money increasingly rewards pure mathematics and computation. In 2026, a polyhedra catalog took the $250,000 STS award and an origami-folding simulation took the $100,000 ISEF award — neither one a lab experiment in the traditional sense.
