The top Sino-U.S. tech titans now reach the trademark total market capitalization of $4 trillion as of July 2018.

The east-west tech rivalry intensifies between BATs (Baidu, Alibaba, and Tencent) and FAANGs (Facebook, Apple, Amazon, Netflix, and Google). These Sino-U.S. tech titans now reach the trademark total market capitalization of $4 trillion as of July 2018. The U.S. tech giants aim to achieve digital supremacy worldwide; yet, only Apple and Amazon receive open access to the Chinese market. The Chinese tech leaders, Baidu, Alibaba, and Tencent dominate in Mandarin online search, e-commerce, mobile payment encryption, social media, and digital communication.

These Sino-American tech titans avoid each other in their home markets, and the recent bilateral trade frictions make it less likely for a fundamental clash to happen in these respective markets. In light of tariffs, quotas, and other trade barriers, the Trump administration bans China Mobile from acquiring access to the U.S. market due to national security concerns. In response to the recent M&A request of Ant Financial Group (an affiliate of Alibaba in China), the Trump administration vetoes Ant's acquisition of a U.S. payment firm. Several investment restrictions prevent Sino-U.S. tech titans from entering the uncharted territory on the other side of the northern hemisphere.

For this reason, these Sino-U.S. tech titans expand their reach and impact in third countries with high population dividends, such as Brazil, India, and Indonesia etc. FAANGs and BATs are now aggressively seeking both domestic and foreign M&A targets, especially unicorns or tech startups each with $1 billion market valuation. These unicorns tend to specialize in specific R&D innovations in order to package themselves for lucrative takeover deals.

As global income and wealth increasingly concentrate in the Sino-U.S. tech titans, consumer benefits manifest in the form of technological improvements. Whether this pecuniary concentration would exacerbate global economic inequality remains an open controversy. Rampant socioeconomic polarization and inequality may be the inevitable by-product of this income and wealth concentration in the Sino-U.S. tech titans. This trend raises a red alert due to grave antitrust concerns, and both U.S. and Chinese regulators and policymakers must attend to the key implications for better economic reform. The law of inadvertent consequences counsels caution.
