The Heisman’s Real Voters Are on Kalshi and Polymarket This Year

Welcome to the 2025 Heisman race, where the sportsbooks don’t matter, the media doesn’t matter, and the voters don’t matter, because Kalshi and Polymarket have already reduced the entire award to a two-man duel decided by one football game on Saturday.

Ohio State vs Indiana. Julian Sayin vs Fernando Mendoza.
Winner gets confetti, a playoff spot (so does the loser in this case), and probably a bronze trophy shaped like a man stiff-arming regulators.

Let’s break down how the markets are treating this like the presidential election, the Super Bowl, and the Hunger Games all wrapped into one.

Kalshi

  • Julian Sayin – 36% (Yes price: 37¢)
  • Fernando Mendoza – 34% (Yes price: 34¢)
  • Diego Pavia – 28% (hanging in like a perfectly average 28%)
  • Everyone else – basically décor

Sayin and Mendoza are separated by just 2 percentage points, which in Kalshi terms means “everyone is pretending they already know who will win Saturday.”

Polymarket

  • Julian Sayin – 34%
  • Fernando Mendoza – 33%
  • Diego Pavia – 24%
  • Others – rounding errors with shoe contracts

Polymarket traders woke up today and said:

“What if… it’s actually a coin flip?”

And honestly? That’s the correct take.


Why This Race Is Simple: Win Saturday, Win the Heisman

The markets are forming a giant neon sign:

Big Ten Champ QB = Heisman Winner.

  • Sayin wins? He jumps from mid-30s to “lock it in, boys.”
  • Mendoza wins? You might as well engrave the trophy before the commercial break.

The voters want an answer that requires zero thinking. A conference title in primetime gives them exactly that.

The moment each QB’s team wins big? Their Heisman line goes vertical. 

The moment each QB’s team loses? Their line collapses like a poorly insurable crypto exchange.

The markets aren’t valuing the player. They’re valuing the result of one single game.


How to Actually Bet / Trade The Heisman

1. Pick the Game Winner, Not the Trophy Winner

Because they’re the same bet.

If you think Ohio State beats Indiana → Sayin at 34–37¢ is stupidly cheap.
If you think Indiana pulls off the upset → Mendoza at 33–34¢ is the value side.

This is a derivative of the Big Ten Championship. The Heisman market is basically a shadow spread.

2. Micro-Arbitrage Between Kalshi and Polymarket

These differences are small, but exploitable:

Sayin:

  • Kalshi: 37¢
  • Polymarket: 34.9¢

Mendoza:

  • Kalshi: 34¢
  • Polymarket: 34.0¢

Sayin is the arbitrage opportunity right now.

The Strategy:

  • Buy Sayin on Polymarket at ~35¢
  • Sell Sayin on Kalshi at 64¢ (No side)

The gap is wide enough to scalp actual EV for traders who like to brag about risk-free returns while still eating ramen.

3. The Live-Trading Spike Method

Because both markets move faster than your ex after a blue check slides in.

The moment Ohio State scores:
Sayin jumps 5–10¢.

The moment Indiana strikes first:
Mendoza spikes instantly.

If you’re fast, caffeinated, and morally comfortable trading like a teen on Adderall, you can:

  • Buy both pregame
  • Wait for the first TD
  • Sell the spiker
  • Let the cheaper one ride

This is the closest the Heisman gets to day trading.


Can Diego Pavia Still Win?

Technically yes.
Realistically no.
Emotionally? Also no.

He’d need:

  • A catastrophic meltdown from both Big Ten QBs
  • A nationwide voter strike
  • Maybe a viral TikTok

Pavia at 24–28% is pure narrative nostalgia. The markets have already moved on.


Final Read: This Is a 60-Minute Trophy Race

The Heisman is no longer a season-long award.
It’s not a résumé contest.
It’s not a legacy trophy.

It’s a one-game referendum.

Beat your rival under the lights → claim your crown.
Lose? See you next season… maybe.

Saturday decides the Heisman.
Next weekend only confirms it.
