What Did I Notice Redeeming the Code Myself?
Redeeming the Kalshi MLB promo code LABS offer took me under 10 minutes start to finish.
I opened my own account in March, typed LABS into the promo field, and funded it with a $20 debit card deposit that cleared in roughly 90 seconds. ID verification took about four minutes, mostly waiting on the selfie scan.
I split my $25 across three MLB contracts (two moneyline markets and one series price) and my bonus tier posted that same evening. I drew the $15 tier, which matches the 70% share above.
Setting a limit order at $0.42 per contract felt closer to a brokerage app than a sportsbook, and the fill notification hit my phone instantly. One detail I still appreciate: the order ticket shows your max payout per contract in plain dollars, so you see the downside before you confirm.
