Kalshi College Admissions: How Admission Rate Wagers Would Work
On October 19 and 20, 2026, Kalshi shook up the college admissions world and moved to launch wagers on college admissions, filing paperwork with the CFTC to list contracts on admission rates at 22 selective universities, including all eight Ivy League schools, Stanford, and MIT.
If they launch, legal adults will be able to wager on yes-or-no questions such as whether a given university accepts fewer than 4% of applicants for the class entering in fall 2027. Each question will then be settled against that university's own published statistics months after decisions go out.
Below, we explain how these markets work, which numbers decide them, what recent figures reveal about what traders would be forecasting, and how to read the same official information yourself.
What is Kalshi?
Kalshi is a booming prediction market, an exchange where people buy and sell yes-or-no contracts tied to real-world events. Prices move between 1 and 99 cents, and each contract pays $1.00 if the event happens and nothing if it doesn't, so a price of 30 cents means traders collectively put the chance at roughly 30%. Users trade with each other, and the exchange charges fees.
Tarek Mansour and Luana Lopes Lara founded the company in 2018 after meeting as undergraduates at MIT. They went through Y Combinator, the Silicon Valley startup accelerator, in 2019. In November 2020, after about 18 months of work with regulators, the company received federal approval as the first federally regulated U.S. exchange built for event contracts. Its listings have centered on sports, politics, and economic figures such as inflation and interest rates, and it raised $1 billion at a $22 billion valuation in May 2026.
Because prediction markets like this one answer to a federal regulator instead of state gaming boards, the platform accepts users who are 18 or older, while state-licensed sportsbooks usually set the minimum age at 21.
What did Kalshi file for college admissions?
The exchange filed 22 separate notices, one per institution. Each covers two statistics: the first-year admission rate and the total number of applicants. Traders would bet on whether either figure lands above, below, at, or between values the exchange sets.
Group | Universities in the filings |
Ivy League (8) | Brown, Columbia, Cornell, Dartmouth, Harvard, Penn, Princeton, Yale |
Other private (12) | Caltech, Carnegie Mellon, Duke, Johns Hopkins, MIT, Northwestern, Notre Dame, Rice, Stanford, University of Chicago, Vanderbilt, Washington University in St. Louis |
Public (2) | UC Berkeley, UCLA |
On October 22, the exchange filed a second set that compares institutions against each other, asking whether Harvard will post the lowest rate in the Ivy League and whether it will see the largest year-over-year rise or drop. Those items settle on the Integrated Postsecondary Education Data System (IPEDS), the U.S. Department of Education's database of statistics.
A spokesperson for Kalshi has said that the company views selectivity as an economic figure tied to jobs and household spending. They are pushing heavily to launch before spring 2027 and told The Chronicle of Higher Education it hopes to list them in the coming months. It has historically listed other higher education questions, including the outcome of Harvard's lawsuit over federal funding freezes.
How would an admission-rate contract work?
Each listing names a university, a statistic, an admissions year, a comparison, and a number, for example: "Will the admissions rate at Princeton for the 2027 admissions season be below 4.0%?"
The rate is first-year admits divided by first-year applicants, multiplied by 100, then rounded to one decimal place. The filings work through examples using a hypothetical pool of 48,000:
Offers out of 48,000 | Unrounded | Rounded | "Below 4.0%" resolves |
1,872 | 3.900% | 3.9% | Yes |
1,895 | 3.948% | 3.9% | Yes |
1,897 | 3.952% | 4.0% | No |
1,920 | 4.000% | 4.0% | No |
In that example, two offers out of 48,000 separate a winning position from a losing one.
How will admission rounds be counted?
The count includes every first-year round. For readers outside the U.S., ED is binding: if you're accepted, you commit to attend. Early Action (EA) gives you an early answer without that commitment, and Restrictive Early Action (called Single-Choice Early Action often), used by Harvard, Yale, Princeton, and Stanford, limits where else you can apply early. Regular Decision (RD) is the standard spring round. QuestBridge is a national scholarship program that matches high-achieving students from low-income families with partner colleges. Offers made from the waitlist count too, while transfer and graduate admissions don't.
What doesn't count toward the result?
Anything outside official figures. Only the figure in a university's Common Data Set counts. Each market settles on the acceptance rate a school reports in its Common Data Set, which usually comes out the fall after decisions are released.
What is the Common Data Set?
The Common Data Set (CDS) is a standardized annual report that many U.S. colleges post on their websites. Universities developed it with the College Board, Peterson's, and U.S. News & World Report so every institution answers the same questions with the same definitions. Publishing it is voluntary, and reports appear well after admissions and rejections go out. Harvard, for instance, now releases its admissions figures in October or November after a class enrolls.
You don't need to be an expert to read one of these: search a school's name plus "Common Data Set" and open the most recent file. C1 gives first-year applicant and admit totals. C2 shows how many students were offered a waitlist spot and how many were admitted from it. C21 and C22 give ED and Early Action figures. C7 lists how much weight is put on factors such as rigor of the secondary school record, GPA, test scores, the application essay, recommendations, and activities.
What do Harvard's numbers show about what traders would be betting on?
The trend across four recent Harvard classes makes the mechanics clearer. Offers barely move from year to year, while the size of the pool swings by thousands.
Class | Applicants | Admitted | Rate |
Class of 2026 | 61,220 | 1,954 | 3.2% |
Class of 2027 | 56,937 | 1,965 | 3.5% |
Class of 2028 | 54,008 | 1,970 | 3.6% |
Class of 2029 | 47,893 | 2,003 | 4.2% |
The pool shrank by about 22% between the Class of 2026 and the Class of 2029, and the rate rose a full percentage point as a result, while the number admitted stayed within about 50 students. When a school accepts a stable number each year, a market on its rate works mostly as a forecast of how many people will apply.
That points to where prices will move. Many universities announce early application counts in November or December; Penn, for example, publicized that more than 9,500 students applied ED in a recent cycle. Testing policy also matters. When many colleges dropped SAT and ACT requirements during the pandemic, volume at the most competitive universities jumped. Traders will react to public signals like these, since the filings ban anyone with inside knowledge from trading.
Do Kalshi odds tell you your chances of getting in?
No. If a Duke market trades at a price implying the rate will stay under 5%, that describes the entire pool. Duke's most recent CDS shows 4.7% of 61,935 accepted across ED, QuestBridge, and Regular Decision.
Your own odds depend on the round you choose, your academic record, your essays and activities, and the group you're compared against. Published figures already differ by round at the same school. According to 2025-26 CDS figures, Brown accepted 6.3% overall and 17.9% in ED, and Wash U in St. Louis accepted 11.9% overall and 27.0% in ED. Early pools are self-selected, so a higher early figure doesn't transfer one-for-one to any individual's chances.
New listings also tend to start thin. The exchange's own guidance treats roughly $10,000 in volume or about 20 unique traders as the point where its forecasts sharpen. Until then, a price can reflect a handful of people.
Can high school students trade Kalshi contracts?
No. The exchange doesn't allow anyone under 18 to open an account. Students who turn 18 during senior year aren't automatically barred, but each filing lists people who can't trade that university's questions:
staff, student employees, and contractors in the undergraduate admissions and financial aid offices, including readers and committee members
faculty and administrators involved in the admissions process or with access to nonpublic figures, including institutional research staff
communications staff with early access to the CDS
employees and contractors of platforms or vendors that process the school's applications
anyone with material nonpublic information about the totals
immediate family and household members of everyone above
Will the admissions markets actually launch?
Filing and listing are separate steps. Self-certification lets an exchange list a new product without prior CFTC approval, as long as the filing comes at least one business day ahead.
The head of the National Association for College Admission Counseling (NACAC), the professional association for school counselors and admissions officers, publicly opposed the idea, and The Duke Chronicle covered concerns that people with early access to admissions figures could profit. The exchange is also defending lawsuits from states, including Ohio, Tennessee, and Utah, that argue some of its products amount to gambling under state law. Its position is that it runs federally regulated financial products, and its filings answer the insider concern with the trading bans listed above.
What should applicants do with this news?
Read the same numbers the traders will be reading by going right to the source:
Download the most recent CDS for each university on your list and note C1, C2, C21, and C22.
Compare like with like. Some colleges fold waitlist offers into their reported figure and some don't, and some publish months after the fact, so headline acceptance rates from different sources will often measure different things.
Check C7 to see which factors each institution ranks as very important, important, or considered.
Base your choice of round and your college list on your own record and the round-specific figures. Market prices on an overall rate aren't designed to inform either choice.
If your high school offers college counseling, bring your CDS notes to that meeting. Counselors can tell you how students from your high school have fared at the same universities, which no market can price.
Frequently Asked Questions
Are Kalshi college admissions markets live yet?
As of October 23, 2026, they hadn't launched, according to Inside Higher Ed. The company plans to allow trading before spring 2027 decisions if the markets go ahead.
Which universities are in Kalshi's college admissions markets?
All eight Ivy League universities plus Caltech, Carnegie Mellon, Duke, Johns Hopkins, MIT, Northwestern, Notre Dame, Rice, Stanford, UC Berkeley, UCLA, the University of Chicago, Vanderbilt, and Wash U in St. Louis.
Can a Kalshi price predict whether I'll get in?
No. Each tracks a university-wide statistic. Your chances depend on your record, your round, and the pool you're compared against.
What can students learn from the company's success?
The admissions filings are a small case study in building a product inside a regulated industry. Mansour and Lopes Lara spent about 18 months getting a federal license before they could operate at all. Lopes Lara has described calling more than 70 lawyers early on, who told them an exchange like theirs couldn't exist. The admissions filings show the same kind of work in detail: choosing one authoritative source, writing rules for rounding and late or corrected figures, and listing exactly who can't trade. That design work decides whether the product functions, and it happens long before any user sees a price.
Students who want to see how founders make strategy calls like these can study them up close at the Venture & Tech Summer Program (VTSP). Over six weeks online, students attend daily lectures and fireside chats with founders and investors, and they work in small teams on an internship project built around a real problem facing a VC-backed startup, which they present to the company's founder at the end. Our partner startups span AI, biotech, fintech, and other industries and are backed by firms including Sequoia Capital, Andreessen Horowitz, General Catalyst, and Y Combinator. VTSP 2027 runs in two sessions, June 8 to July 16 and July 5 to August 13, and applications are open now.
