To determine which of the given options the Universe has the most of, we can analyze the contributions of each category to the overall composition of the Universe.

1. **Dark Energy**: It is estimated that dark energy makes up about 68% of the total energy content of the Universe. It is responsible for the accelerated expansion of the Universe.

2. **Hydrogen and Helium**: These two elements are the most abundant in the Universe, primarily consisting of hydrogen (about 75% by mass) and helium (about 25% by mass). Together, they make the majority of baryonic matter, which is roughly 4-5% of the Universe's total content.

3. **Stars and Planets**: While stars and planets are significant, they represent a small fraction of the Universe's total mass, significantly less than dark energy, dark matter, and even hydrogen/helium.

4. **Dark Matter**: This mysterious matter makes up about 27% of the Universe's total mass-energy content. Dark matter does not emit light or energy, making it invisible and detectable only through its gravitational effects.

### Conclusion
Thus, breaking down these contributions, the predominant component is **Dark Energy**, followed by Dark Matter, then hydrogen and helium, and finally, stars and planets.

**Final Answer: Dark Energy**
