Talk to your boss. That amount so low that there's no question of overreacting: you basically didn't get a bonus. Having worked before in larger tech companies, I would entertain the idea that the amount is a fluke of accounting rules--you said you only started six months ago: maybe there is some kind of vesting rule. It's very likely it's nothing personal. If the company is indeed doing as well as you say, they would either give you no bonus or something real. If it's the former, they'd probably be talking to you about leaving. It's unlikely that this is some kind of passive-aggressive gesture because they secretly want you gone. Unlikely, but not impossible: bad management definitely exists, so anything is possible. If this was an intentional act then definitely leave at your earliest convenience. But I bet it wasn't.
