I'm assuming that he has a battery of attorney's that already reviewed all of the loopholes and legal minutia and have their "defense" pre-crafted.
Sounds like the angle they're going for is claiming it's a "job opportunity"
a job opportunity, saying winners “will be selected to earn $1M as a spokesperson for America PAC.” The two winners picked over the weekend have appeared in promotional videos on the super PAC’s account on X, formerly Twitter.
It's a legal grey area, as there have been other instances (even this past year) that have involved "dangling a carrot" to try to get people to register to vote.
Ariana Grande and voter-registration nonprofit HeadCount have launched a 'Wicked' contest aiming to increase voter registration among young people.

While it's pretty clear that Musk's little contest is specifically trying to identify and register likely Republican voters, one could make the argument that Ariana Grande, allowing people enter in a contest to attend the premier of a broadway show (and win free cosmetics from her personal line) is certainly trying to isolate and target a particular type of voter as well.
...and while the law specifically pertains to federal elections, other organizations have tried these sorts of antics in local elections in the past
US’s oldest nonpartisan Latino voter participation organisation is trying to combat voter apathy but critics say prize destroys integrity of democratic process

Ironically enough, Trump actually tried to sue the Nevada Native Vote organization for doing something very similar...it wasn't a million bucks obviously, but they were offering Visa gift cards in "raffle format" for people who showed they voted.
Speaking before North Carolina Republicans, former President Donald Trump on June 5 rehashed a number of falsehoods abou

(while his overall speech was riddled with conspiracy theories and fibs, the tiny nugget of it that actually had merit, that was lost in the sea of falsehoods, was that Nevada Native Vote was questionable in their gift card incentive program)
Ben & Jerry's found themselves in hot water for running such a promotion as well (and they responded to a cease&desist by just expanding their free ice cream day to everyone instead of just the people who voted lol)
The winner will be chosen from those who sign a petition by the tech billionaire's Trump-supporting group.

But the strategy may be covered by a loophole under US election law because no-one is being directly paid to vote - despite introducing money into a process that could identify likely Trump voters.
In the US, it is illegal to provide payments to get people to vote - not only for a certain candidate, but to simply cast a ballot.
The rule prompted ice cream-maker Ben & Jerry's to give its product free to everyone on election day in 2008, having initially planned to limit it just to those with an "I voted" sticker.
