The production of Bitcoin BTC blocks depends on two major mining pools

CoinWorld reported:
Bitcoin mining competition always produces leaders. After the recent halving, the network is now dominated by only two mining pools, which generate over 60% of the blocks.
Bitcoin mining is entering a new stage of maturity, where mining pools are competing for the reduced block rewards. Typically, around 50% of the blocks flow to four leading pools. However, the shift in investments has changed the landscape of the mining industry, making two major mining pools the top block producers.
The two largest mining pools in terms of output are Foundry USA and Antpool. Together, they possess over 51% of the hash power, theoretically capable of attacking the Bitcoin network. So far, Bitcoin has not seen collusion among producers, but it would require at least three pools to control 51% of all mining.
Within a seven-day timeframe, these two pools also produced 55% of all blocks, with over 29% flowing to Foundry. The pools do not necessarily control all the mining machines, as only a portion of the hash rate is under their direct control. Theoretically, miners can choose to switch pools, but most miners still remain with the major producers for a higher chance of reward.
Update: Two entities now control 63% of the BTC block production, with their known proxies controlling 76%.
