TSMC is pulling further ahead in the business of making chips for other companies, which is good for TSMC and bad for Samsung, now nearly tied with China's SMIC.

• TSMC's share of the contract chipmaking market rose above 72%, while Samsung's slipped to under 6%.
• The whole market hit a record quarter, lifted by demand for AI server chips, with TSMC's most advanced production lines running flat out.
• SMIC grew fastest of the big players and is now within half a percentage point of Samsung, threatening to push it out of second place.
• Samsung is making record profits on memory chips, but its contract chipmaking arm is falling behind the market.
• New foundry orders Samsung won from Tesla and Nvidia are not expected to show up in its numbers until next year.

Outlook: Samsung risks losing second place in contract chipmaking to SMIC before its new Tesla and Nvidia work starts paying off.
