In The Phantom Menace Anakin Skywalker participated in the Boonta Eve Classic, a pod race on Tatooine. After winning the race did Anakin receive anything from the race's hosts, the Hutts, i.e. a purse or any other sort of winnings?
Anakin was going to win money from the race through Qui-Gon's bargaining, but Qui-Gon essentially traded the money for the parts to repair their ship. He also won the Boonta Cup, though it is unclear whether this was an actual cup (like the NHL's Stanley Cup), or merely the name of the prize money. Personally, the only thing he actually received was his freedom, and that too was more a result of Qui-Gon's bargaining.
From the Episode I film script:
WATTO So, you supply the Pod and the entry fee; I supply the boy. We split the winnings fifty-fifty, I think.
QUI-GON Fifty-fifty!?! If it's going to be fifty-fifty, I suggest you front the cash for the entry. If we win, you keep all the winnings, minus the cost of the parts I need... If we lose, you keep my ship. WATTO thinks about this. ANAKIN tries not to be nervous.
QUI-GON Either way, you win.
Additionally Anakin's Podracer was sold to Sebulba after the race, providing money that they gave to Shmi Skywalker.
Anakin Skywalker was a slave when he participated in the race. It is unlikely he personally won anything. On a side note, he did secure his own freedom in winning, due to the bet between Qui-Gon Jinn and Watto.
Other answers are referring to the wagers and such surrounding the race, but I think you're asking about whether there was any prize for winning the race itself, or if it was just a prop for wagers. The only canon reference to any prize or award to the winner of the Boonta Eve Classic Podrace appeared in the novelization of Episode III:
Not because of the overwhelming odds, or the danger he was in; he didn't care about odds, and he didn't think of himself as being in any particular danger. A few wings of droid fighters didn't much scare a man who'd been a Podracer since he was six, and had won the Boonta Cup at nine. Who was, in fact, the only human to ever finish a Podrace, let alone win one.
