This is unlikely. Apple's CPU budget for it's devices is likely much higher than anything Qualcomm's customers are willing to pay (vs the current snapdragon pricing). Apple's CPUs are very very large and consequently relatively expensive. As an example, a latest gen snapdragon 835 has 3 billion transistors, while Apple's A11 has 4.3 billion.
And those numbers severely understate the difference since, IIRC, a much larger fraction of Apple's SoC transistor budget is devoted to its application processors.
EDIT: Found an image. More a simple understatement than a severe one.
Of course competitors want more powerful options, and they certainly have the budget for it given the pricing of premium Android devices.
Qualcomm simply fell behind. While Apple went for powerful, enormous cores in small numbers, Qualcomm and friends bet on simpler, smaller cores. Apple has started copy/pasting their fantastic cores, yielding the enormous transistor counts.
I admit to being a skeptic when Apple went off to do their own thing, sure that a whole industry (and options like the Tegra) would make them eat their hat. Apple executed and are in a remarkable position now.
