On the first day of trading in 2022, the Silicon Valley company's shares hit a record of $US182.88 around mid-day.
The world's most valuable company is the first to reach the latest milestone as investors bet consumers will continue to shell out top dollar for iPhones, MacBooks and services such as Apple TV and Apple Music.

"It just shows you how far Apple has come, and how dominant it is seen as in the majority of investors' eyes."
Apple shared the $US2 trillion market value club with Microsoft - now worth about $US2.5 trillion. Alphabet, Amazon.com and Tesla each have a market value above $US1 trillion.
"The market is rewarding companies that have strong fundamentals and balance sheets, and the companies that are hitting these sort of huge market caps have proven they are strong businesses and not speculation," Scott Wren, senior global market strategist at Wells Fargo Investment Institute, said.
The rapid embrace of technologies such as 5G, virtual reality and artificial intelligence has also helped these stocks become market darlings as investors moved towards cash-rich companies and away from businesses that have been more sensitive to economic growth.
Apple's quick adoption of 5G technology provided a big boost. It recently launched iPhone 13 in its second wave of phones with 5G.
In China, one of Apple's biggest markets, it continued to lead smartphone sales for the second successive month, beating rivals such as Vivo and Xiaomi, recent data from CounterPoint Research showed.
Apple's stock touched a record high of $US182.88 on Monday, putting its market value just above $US3 trillion, based on about 16.4 billion outstanding shares.
