Ethereum's capitalization is still the highest among many top altcoins, and according to CMC, Ethereum's market cap is currently 2 times that of XRP, so I think it's still a long way for XRP to surpass Ethereum. But anything can happen in the crypto world, if something good happens, XRP might approach ETH. But it doesn't seem like it will happen anytime soon.
Eth has built its position with its smart contract initiative and EF's efforts over the years; it's not simply a blockchain copying BTC's ideas or other POW blockchains in the market. If Xrp wants to dethrone Eth, it needs a new idea, a new vision, not just a convenient global money transfer network.
Even though Eth is facing many difficulties, many other L1s in the market are still lagging behind in TVL, liquidity, and ecosystem value. As soon as Eth recovers thanks to internal reforms at EF and the Pectra upgrade, investors will FOMO into ETH again and no longer think about Eth's minor issues.
For XRP to overtake Etheruem is just a matter little time, as you can see, over the past eight months, Etheruem has failed to perform, and till this moment, Ether token has not shown any significant movements even when Bitcoin pumping with with records All Time High, Ether has been very weak.
Now, XRP and few other altcoins has been doing great, fortunately, Xrp and few others altcoins has been enlisted as part of the Bitcoin strategic reserve to further boost it potential on the market and possibly overtake Etheruem at the second position on the Coinmarketcap ranking.
Well, as far as the crypto market are concerned, anything can happen, but the best will remain on the top positions.
