The Battle of Chicago takes front and center stage in baseball today, Tuesday, Aug. 18, 2026, as the White Sox take on the Cubs at 8:05 p.m. ET on TBS.

Why the ProphetX Promo Code TANBONUS Fits White Sox vs. Cubs
What appealed to me when signing up with the ProphetX promo code TANBONUS is the ratio of how the $20 welcome offer works. A $10 buy-in is small enough that a rivalry game such as White Sox-Cubs becomes a low-commitment first market. Plus, the $20 credit you receive afterwards doubles your working balance to trade on other prediction markets.
ProphetX is a peer-to-peer exchange, not a traditional sportsbook. You trade against other users rather than against a house line, so pricing moves with demand as injuries, starting pitchers, and lineup changes are announced. A crosstown rivalry in prime time such as the battle of Chicago provides tighter prices and better liquidity.
Worked Example: White Sox Moneyline
Say you sign up with the ProphetX promo code TANBONUS from Action Network, deposit $10, and put the full amount on my personal White Sox vs. Cubs prediction of White Sox moneyline (-110)
- If the White Sox win: the trade returns roughly $9.09 in profit plus your $10 stake.
- If the White Sox lose: you are out the $10.
Either outcome unlocks the $20 bonus, so don't sweat getting your pick right for that reason. Once your initial qualifying trade settles, $20 in bonus funds are credited. Keep in mind that bonus stakes are not returned with winnings, so a $10 bonus trade at a price of -110 pays just $9.09 in profit rather than $19.09.
Before You Trade
Once you claim ProphetX promo code TANBONUS and $20 new player offer, check the probable starters and posted lineups before locking any of your MLB picks in. Late scratches move exchange prices faster than they move sportsbook lines.
