To give a bit more of context. Ethereum at its funding stage, raised 18 million, when the entire cryptocurrency market was 11 billion.
This amounts to 0.16% of the total market cap.
EOS raised 4 billion dollars, with the current market at 333 billion dollars, that gives makes it 1.2% of the total market cap.
This still makes EOS funding a magnitude larger than Ethereum, but not a completely unreasonable amount.
Ethereum conducted a crowdsale in Ethereum with 2,000 Ether being provided for one Bitcoin. When the crowdsale was completed, the amount of Bitcoin raised only represents a miniscule fraction of the Bitcoin market cap. EOS conducted it's ICO accepting Ether. At near the time of completion, the market of the generated funds represents around 7% of the total Ethereum market cap. It will be interesting to see what happens if/when EOS goes to sell this significant holding.
