Need idea validation. Nothing built yet, so not selling anything

I've been sitting on a concept for sometime and finally need a gut check from people smarter than me.

The premise is simple:

→ Brands need people to actually watch their ads

→ People hate watching ads

→ What if watching an ad gave you a real shot at winning real money?

No purchase. No entry fee. No catch.

You watch. You earn. (How exactly is USP and can’t share just yet)

The legal structure is clean (sweepstakes model). The economics work. The tech is straightforward.

What I don't know yet: do people actually want this?

Three honest questions before I build a single line of code:

1. Would you watch a 60-second ad if it gave you a real (not points, not coupons) chance at $500 or more, literally no upper cap

2. What's your gut reaction excited, skeptical, or "sounds like a scam"?

3. Is there a reason this obviously doesn't work that I'm missing?

I'd rather get crushed in the comments than build the wrong thing.

Be brutal please
