With two new iPhones now in stores, Apple is expected to turn in its best holiday quarter ever. According to KGI Research analyst Ming-Chi Kuo, the Cupertino-based company will sell a whopping 82 percent more iPhones this quarter compared to last.

In total, Kuo believes Apple will put 71.5 million iPhones in the hands of consumers this quarter and could climb even higher if the supply chain holds up. If the estimates pan out, it would represent 40 percent year over year growth.

Under current circumstances, Kuo expects the iPhone 6 to account for nearly 60 percent of all sales during the quarter, or roughly 41.65 million units sold. The iPhone 6 Plus checks in with 15 million units sold while the 5S, 5C and 4S are expected to collectively account for 14.75 million units sold.

The iPhone business alone could bring in as much as $46.5 billion in revenue during the quarter.

Apple’s iPhone 6 Plus continues to be available in limited quantities. According to Kuo, this indicates robust demand while also confirming concerns regarding constraints within the supply chain. It’s unclear exactly which component(s) are slowing down production but by all accounts, Apple is turning out more iPhone 6 units than they are of the larger model.

Apple’s stock has once again hit an all-time high on the estimates. As of writing, shares are trading at $119.19 which is down just slightly from the $119.35 record earlier today.
