The US economy is still number 1, when it comes to finance, service-based businesses and some high-tech sectors.
The economy of China is number 1 in terms of industrial capacity and production(and also some high-tech sectors).
India is still a very poor and underdeveloped country, but the Indian economy is growing pretty fast. AFAIK, India has higher GDP growth in comparison to China.
The Russian economy is basically oil, gas, grain and weapons. The Russian industrial military complex is what keeps the Russian economy growing. I don't know what will happen, after the war in Ukraine ends. Maybe the Russian economy would adapt pretty fast, or maybe there will be some short term recession in Russia.
