Mr. Thiel has said in interviews that the benefits accruing to tech investors like himself should be more widely shared outside a few ZIP codes in New York and around San Francisco. One role of the meeting is to spur ideas for changing this situation. A spokesman for Mr. Thiel declined to comment.

In Apple’s case, Mr. Trump has said he told its chief executive, Timothy D. Cook, in late November that he wants the company to build “a big plant” in the United States — or even better, “many big plants.”

Apple itself does not do any manufacturing in the United States. A contractor, Flex, manufactures high-end desktop computers on its behalf in Austin, Tex., employing about 2,000 people. A vast majority of Apple’s production is in China, where there is an enormous ecosystem devoted to it. Many economists say that reproducing such an interlocking web of suppliers here would push the cost of iPhones up considerably.

Mr. Trump also tangled with Jeff Bezos, the founder and chief executive of Amazon, during the campaign, saying that Mr. Bezos has “a huge antitrust problem because he’s controlling so much.”

Amazon is overwhelmingly the dominant force in e-commerce. In its original business of books, for example, it is by far the most important retailer of both physical and electronic books. In several spheres, it is developing technology that eliminates the middleman — in other words, jobs. This week, the company debuted a new system for operating stores without cashiers.

How much Silicon Valley is reconciling itself to the thought of President Trump is a complicated question. Last week, David O. Sacks, the chief executive of the human-resources software start-up Zenefits, said he was stepping down after having had discussions about helping Mr. Trump’s transition team. Mr. Sacks is a longtime associate of Mr. Thiel’s.

If there are some overtures being made in Silicon Valley, there are also some lines being drawn.

Chris Sacca, a prominent venture investor, said there was only one path for those attending next week’s meeting: defiance.
