The FantasyLabs crew took a look at the Polymarket promo code MLB LABS, and it’s an easy one to like. New users drop in $10 and get $20 in trading funds, with no qualifying trade to clear first. It’s good to go for Mariners vs. Yankees on Tuesday, first pitch 7:05 p.m. ET on TBS from Yankee Stadium.
If you’re new to Polymarket, it’s the biggest MLB prediction market out there by volume. You buy contracts anywhere from a penny to 99 cents, and a winner pays out a flat dollar. So a $0.56 Yankees contract just means the market gives New York about a 56% shot to get it done. My early Mariners vs. Yankees prediction is the Yankees moneyline at around $0.56, since New York’s the home favorite with the better pitching setup tonight.

Polymarket Promo Code LABS: Trade on Mariners vs. Yankees Prediction
I like the Yankees tonight. New York’s got lefty Ryan Weathers (3.79 ERA) going, and Seattle’s bats haven’t done much against lefties this year, so that’s a good matchup for the home side. The Mariners run righty Bryan Woo (4.31 ERA) the other way. Throw in two of the better bullpens in baseball and this looks like a tight, low-scoring one, which is right where I want the home favorite. Sign up with the Polymarket promo code MLB LABS, and trade on the Yankees to win ($0.56) with one of the best prediction market promos from FantasyLabs.
