After some technical difficulties, starting here:

It appears that the high tide of hunger for chips is lifting all boats.

"...while SMIC came in fifth with $1.344 billion in its ongoing attempt to build up China for its chipmaking war with the U.S. Though fifth place isn't impressive by itself, consider that SMIC grew by 21.8% QoQ to achieve that revenue haul, granting it 5.3% of the total foundry market share."

But the market is cyclical. After a big build-out, I expect it to drop towards the end of 2023.

The expansion by China's largest chipmaker comes as the shortage rattled the automotive and electronics industries, spurring new capacity plans by firms like Taiwan Semiconductor Manufacturing Corp Ltd (2330.TW) and GlobalFoundries.
SMIC said it agreed to build a production line with monthly capacity of 100,000 12-inch wafers in the Lingang Free Trade Zone (FTZ) in the Pudong district of China's business hub.
The plan will focus on integrated circuit foundry and technology services on process nodes for 28-nanometers and above, backed by a joint venture majority-owned by SMIC."

SMIC clearly expects to be able to get the SME from somewhere.

"The semiconductor industry is notoriously cyclical. As such, semiconductor companies are subject to the ups and downs of regular chip cycles tied to the law of supply and demand.

When conditions are favorable, chipmakers have trouble keeping up with demand. But when supply exceeds demand — either through overproduction or a pullback in end markets — prices fall. In turn, so do chip manufacturing levels."

Chinese semiconductor manufacturers increased their shipments of chips in July compared to June and set a new all-time record. Every day, the semiconductor industry in China produced over a billion integrated circuits (ICs), but it is going to take a lot of time before the country's production of semiconductors outpace imports. " ...
"Chinese semiconductor producers (including makers of 3D NAND, DRAM, and logic components) manufactured 31.6 billion chips in July (up 41.3% compared to July, 2020), over one billion of ICs per day. To put the number into context, the Chinese semiconductor industry made 30.8 billion chips in June and 29.9 billion ICs in May.

So far this year, Chinese semiconductor makers have produced 203.6 billion of chips, according to the National Bureau of Statistics, reports the Southern China Morning Post. That's up 47.3% year-over-year, a very impressive result, especially considering the fact that companies like Semiconductor Manufacturing International Co. (SMIC) cannot easily get the equipment they need from American companies, as they're blacklisted by the U.S. government. "

Even if demand lowers in 2023, will it do so asymmetrically? They ask about percentage, not quantity, so if the decrease is symmetric then it should not decrease percentage
