Have market forces eroded Apple's monopsony power for chips?

To see how monopsony works graphically, see the Wikipedia article. Monopsony means one buyer (whereas monopoly means one seller). Similar to what happens in monopoly where the price is higher than in competition and the quantity produced is lower, in monopsony less is produced and sellers get a lower price because the one buyer has market power.

And that is something that Apple has been accused of. See Apple Is America’s Semiconductor Problem. Excerpt:

"Apple’s sheer size as a buyer puts this into perspective. In 2022, Apple bought $67 billion of semiconductor chips, a full 11% of the global market for chips across all industries. Apple buys a far larger share of smartphone and computer semiconductors, given that it accounts for half of global smartphones sales and earns 85% of all smartphones profits. Apple’s supply agreements with U.S. mobile operators demand that Apple products get the deepest subsidies and the largest share of sales."

But the recent increase in demand for chips for AI purposes means that there are many more buyers and it looks like Apple's influence is decreasing. See Apple to Raise Prices Due to Memory Chip Crunch, Tim Cook Says: The CEO tells the Journal in an exclusive interview that soaring costs make price increases ‘unavoidable’ by Rolfe Winkler of The WSJ. Excerpts:

"Apple plans to raise prices on its products to offset the surging costs of memory and storage chips, Chief Executive Tim Cook said"

"“There’s less supply at a time when consumers want devices and the memory guys are passing along huge price increases,” said Cook. “We definitely need memory pricing and supply to return to reasonable levels for consumer products. That’s the bottom line.”" (there is less supply for Apple)

"Memory companies are building more factories: Morgan Stanley forecasts that production capacity for DRAM wafers, the silicon discs on which chips are patterned, will grow 30% by 2027. Yet as suppliers prioritize the specialized AI memory, wafers for consumer tech will fall up to 15% short of demand, Morgan Stanley estimates." (so if there is more demand now with more buyers more will be produced meaning the monopsony power is being reduced)

"Companies that make PCs, game consoles, smartphones and more have raised prices"

"Morgan Stanley estimates a 15% bump for prices of smartphones and PCs in the U.S. this year."

"It is unclear how Apple could match, let alone beat, the deal terms that AI hyperscalers are offering to lock up supply. Those companies are signing three-to-five year agreements with huge cash prepayments that Apple is unlikely willing to match"

"Historically it has used its heft to wring the lowest prices out of suppliers, playing them off each other and leaving them little profit. As AI companies have stormed into the market, suddenly Apple has to wait in line." 

This last passage shows that Apple had some monopsony power that is decreasing since they used to be able to play suppliers off each other with little profit (meaning a low price as monopsony predicts) but now they have to wait in line because there are more buyers they have to compete with.
