The United States has been a leader in microchip design with dominant companies like Nvidia, Intel and Qualcomm, but it risks a big drop in global market share without government support for the sector, warned a report released on Wednesday.

   The U.S. share of chip design revenue has been slipping in recent years, dropping to 46% in 2021 from over 50% in 2015. Without government support, that could drop to 36% by the end of this decade, according to the analysis released by U.S. industry body Semiconductor Industry Association (SIA) and Boston Consulting Group.
