Upper bowl tickets are going for as low as $185. Upper bowl tickets which are premium, such as center court, or near row 1 go for around $300.
It's very interesting how many tickets are listed for sale in the upper bowl and are asking for over $350-400 and they aren't even premium upper bowl seats. There are almost no sales around this price for upper bowl tickets either. There are hundreds of tickets like this.
I expect to see upper bowl tickets decrease in price from around $185-220 to closer to $140 in the coming days. I don't see how it would be possible to have a price spike. We are coming up to the last 2 weeks before the game. I wouldn't be surprised to see them come down to even $120 in the last week. I already have seen packs of 4 tickets having accepted bid offers for $150.
These guys either will start accepting bids for much lower than their asking price, or start decreasing the asking price.
Leading up to the Brown vs Steelers game, the price got over $190 for cheap upper seats. I'm talking about row 32, no alcohol section. The largest marketplace, StubHub, had less than 600 tickets available the last week before the game. This is less than 1% of total stadium available. The last day before the game was close to 350 tickets.
The Cavs currently have 6% of the total stadium for sale on FlashSeats. The demand simply isn't there for the price they are asking. Of course there will be some people who just say sure I'll go the game, but there are many many people who will sell.
