Perhaps. If a third party candidate gets 5% of the vote, they're eligible to draw public money from the Presidential Election Campaign Fund. That could be huge.
And aside from that, numbers build legitimacy. If a third party is obviously not going to win, but gets 10% of the vote, we start taking it seriously, and it can build on that success over multiple elections, just like individual candidates do.
The 'wasted vote' trope assumes that the sole point of a vote is to elect a candidate. Your vote is also an act of free speech - it can send a message to your fellow citizens and your government. Even in our stupid two-party system, politicians watch which way the wind is blowing.
