Ante means before, just as pre does. An antenuptial agreement is the same thing as a prenuptial agreement, that is, an agreement entered into by the husband-to-be and the wife-to-be prior to the marriage. Ante = before nuptial = marriage An antenuptial agreement is the same as a prenuptial agreement. It is a legal agreement made between a man and a woman before marriage, typically to discuss division of assets should they eventually divorce.
Upping the ante comes from betting games. The ante is the amount that all players must commit to the pot before the game begins. (The pot is what is won in the game, and will be the total of the ante plus all bets during the game.) Because a player must at minimum ante up, or pay the ante, in order to be allowed to play the game, upping the ante can quickly demonstrate how serious, committed, and solvent a player is. The significance of upping the ante is that it increases the overall cost of the game, hence the idiomatic meaning of increasing the cost or risk of something.
