The Boston Red Sox face the New York Yankees, with first pitch scheduled for 8:00 PM ET. The percentages below are implied probabilities converted from sportsbook-style American odds; they are not Polymarket share prices, and they may not add to 100% because of the bookmaker margin.
Game Winner and Run Line
The Red Sox moneyline is +120 (45.45% implied probability), while the Yankees are -142 (58.68%). On the run line, Boston +1.5 at -192 implies 65.75%, and New York -1.5 at +158 implies 38.76%.
Total Runs
The total is 6.5 runs: over 6.5 at -122 implies 54.95%, and under 6.5 at +100 implies 50.00%.
What $50 Buys
Using the listed sportsbook prices, a $50 stake would return about $110 total on the Red Sox moneyline (45.45% implied probability), or $85.21 total on the Yankees moneyline (58.68%). A $50 stake on Red Sox +1.5 (65.75% implied) would return about $76.04 total; Yankees -1.5 (38.76% implied) would return $129 total. On the total, over 6.5 (54.95% implied) would return about $90.98, while under 6.5 (50.00% implied) would return $100. Returns include the original stake and are approximate.

How Does Polymarket Work?
Polymarket is a prediction market exchange, not a sportsbook. Users buy and sell shares in an outcome at prices between 1 and 99 cents, and each winning share settles at $1. In this marketplace, the price is the implied probability of an event—meaning a 60-cent share implies a 60% chance of that outcome occurring.
Why Polymarket Promo Code MILE Is the Best Choice for Boston Red Sox vs. New York Yankees
Our team verified this offer by signing up with code MILE, depositing $10, and confirming the $50 trade bonus successfully landed in the account. This promotion stands out because the qualifying deposit is only $10, delivering a bonus that is five times your initial commitment, and the $50 can be spread across multiple markets rather than locked into a single outcome. While the Polymarket price on a favorite for the Red Sox and Yankees matchup is currently pending release, these bonus funds will offer flexible trading power once the market goes live.
