What we see in reality is that companies tend to consolidate into bigger and bigger conglomerates.
It’s easy to see why.
I recently finished reading a book on theory of the firm, a branch of economics which studies where the boundaries of companies end up and why they end up there. For instance, why do companies in-house some functions and outsource others? What’s the equilibrium number of companies in an industry? Why don’t companies end up larger or smaller than observed?
Based on that background knowledge… your empirical claim here is true only in a relatively narrow subset of industries, and the “easy to see why” part is just wrong.
There are many industries where companies do not tend to consolidate, and even in industries where companies do consolidate there’s usually an equilibrium with new companies constantly entering the industry. Larger companies are not always more efficient at producing goods and services—size introduces inefficiencies of its own, and industries vary in the extent to production costs decrease at scale (sometimes production is cheaper at smaller scale!).
On the “why” side of things, there’s no inherent reason why large-scale production has to take place within a single company—many of the benefits of scale can be achieved via multiple independent companies pooling resources (as is commonly the case in e.g. the finance industry). This was the first and primary insight which really kickstarted the theory of the firm—why do some industries see a few giant companies, rather than many smaller companies with resource-pooling agreements? Presumably there are trade-offs between the overhead of contracts and the overhead of company management, and those trade-offs are exactly what the theory of the firm studies.
Restaurants, car dealerships, spas and hair salons, construction, plumbers and electricians, doctors and lawyers. Every industry dominated by small businesses.
Even in some of the sectors you list—like automotive manufacturing—we haven’t seen much net consolidation. We haven’t seen a lot of new entrants, but’s it’s not like the number of car manufacturers is rapidly decreasing either. It’s at an equilibrium, and that equilibrium has a lot more than just one company—which is not something you’d see if economic forces generally favored consolidation.
Restaurants, car dealerships, spas and hair salons, construction, plumbers and electricians, doctors and lawyers.
What you are saying is that services can be provided by small companies.
Fair enough.
But we still can see consolidation there.
Starbucks uses a tactic known as ‘clustering’. They’ll build several cafes right in the same area to obliterate competition. This costs a lot of money, but they can afford it… They even use a strategy called ‘predatory real estate’. They pay more than market rate rents to keep competitors out of a location.

The American automotive market consolidated from more than 250 manufacturers in 1909 to fewer than 50 by 1930. How many companies are there now?
One more example:
At the end of 1985 there were 18,000 banks in the United States. By 2007, this had been reduced to just 8,534, and since then has dropped further. Today, the ten largest U.S. financial institutions own more than 50% of total financial assets.
Of course there have been particular cases where an industry consolidated during a particular period. You made a much stronger claim: that industries in general tend toward consolidation. Pointing to two or three examples where industries consolidated does not provide much evidence for such a claim. On the other hand, pointing to examples where industries did not consolidate provides significant evidence against such a claim.

That period being… any moment in time.

I didn’t point to “two or three examples”, but eleven business sectors dominated by huge conglomerates.
On the other hand, pointing to examples where industries did not consolidate provides significant evidence against such a claim.
You responded with a single sector: services.
Even then, I gave a counter-example showing how big companies can drive small companies away.
And you see that happening all the time: Starbucks, McDonalds, etc.
The consolidation is a process, it didn’t finish yet.
Services are not “one sector”, they’re generally considered a category of sectors, and they comprise a majority of all first-world economic activity. If something is true of the service sectors, then it’s true of the majority of the economy.
Your eleven business sectors are not all dominated by huge conglomerates. Automotive production is, but automotive sales aren’t. Construction isn’t. Electronics isn’t. Finance is mixed bag, depending on the sub-sector. Healthcare isn’t. Insurance has big conglomerates on the backend, but lots of small independent salespeople on the frontend. Internet infrastructure is dominated by large companies, but the volume of small e-companies operating on that infrastructure is massive. Oil and gas is more concentrated than most of these sectors, but I’d still guess that you’ve never looked at the numbers enough to notice the long tail of medium-to-small oil producers (I have seen some of those numbers). Pharma is also relatively concentrated, and there the pressure toward aggregation is real. Retail has a long tail. Telecoms is concentrated, though it’s become less concentrated in recent decades.
Note that, in each of these sectors there do exist large conglomerates. That does not mean that the industry is dominated by conglomerates. The big conglomerates are highly visible and salient; the small companies are not.
So out of these, you’re right on maybe half of them if I’m generous. Overall, it sounds like you’re making a really strong claim without ever having looked at the data, and the data does not back the claim.
Retail is a prime example of consolidation—think of Walmart,
Sales by the 20 largest food retailers totaled $515.3 billion in 2016, accounting for 66.6 percent of U.S. grocery store sales, up from 42.2 percent in 1996. Amazon acquired Whole Foods in the summer of 2017. (Source)
Fast forward to 2020, “Amazon and Walmart are like two elephants wrestling, and all the other retailers in the U.S. are the grass” (Source).
Telecoms is concentrated, though it’s become less concentrated in recent decades.
Telecom is another classic example of consolidation.
A long antitrust case completed in 1984 led to the old AT&T being broken into seven regional Bell operating companies and the much smaller new AT&T.
Less than 30 years later, in 2009 the Department of Justice started to look into whether AT&T and Verizon were abusing the market power they had amassed in recent years.
Now… you don’t have to take my word for it. Google for “consolidation in _____ industry” and you are going to see the phenomenon being repeated everywhere.
You still seem to be missing the key point: if you want to claim that industries tend toward concentration in general, citing particular concentrated industries isn’t going to cut it. You need to argue that industries which don’t concentrate don’t exist (or are at least rare), not merely that industries which do concentrate do exist. That requires a more comprehensive view. You cannot get there just by picking particular industries and arguing that they’re concentrated.

Well… I gave you some examples in trillion-dollar industries and asked for counter-examples.
Many of your counter-examples—car dealerships, spas, hair salons, etc—are niche markets.
Few of them were multi-billion industries, and they provide more examples of consolidation.
Just google for “consolidation in restaurant industry” and you will find articles like “6 reasons for restaurants’ massive consolidation wave”, “Deals and consolidation dominate restaurant industry”.
“With the rise in demand for their service, combined with the dire situation COVID-19 has created for most of the population, platforms such as Uber Eats and GrubHub are facing increased scrutiny over restaurant fees that can range from 10% to 40% of gross transactions, according to restaurant owners. (...)
In the future, retailers and customers can expect to pay even more in delivery fees, as the few delivery conglomerates monopolize the market and limit retailers’ ability to sustain a profitable business.”

Can you give me a few examples? I’ll list a few important industries:
Automotive
Construction
Electronics
Financials
Healthcare
Insurance
Internet
Oil and gas
Pharmaceutical
Retail
Telecommunications
In each one of these, you’ll find a bunch of big players.
For example:
Automotive
Volkswagen (Germany)
Toyota (Japan)
Daimler (Germany)
Ford (US)
Honda (Japan)
General Motors (US)
Internet
Google
Facebook
Retail
Walmart
Amazon
Costco
Even if you consider new entrants (such as Tesla) we are still talking about a few companies that dominate the industry.

Isn’t it? Think of a subcategory.
Lenovo, HP, Dell and Apple dominate 3⁄4 of the computer market.
Samsung, Apple, Huawey and Xiaomi dominate 3⁄4 of the smartphone market.
I could go on and on.

How about the small restaurants? According to “Food Delivery Consolidation: Good For Now, But Not For Long”, platforms such as Uber Eats and GrubHub are taking 10% to 40% of gross transactions:
“With the rise in demand for their service, combined with the dire situation COVID-19 has created for most of the population, platforms such as Uber Eats and GrubHub are facing increased scrutiny over restaurant fees that can range from 10% to 40% of gross transactions, according to restaurant owners.
