Wealth and making a lot of money or having a lot of abundant energy can be shown through a variety of factors in astrology. One way is through Jupiter and Pluto and their relationship to one another. It's actually a very strong indicator!
Jupiter-Pluto & Wealth in the Natal Chart
When looking for indicators of wealth in a natal chart, one of the things you can assess is Jupiter and Pluto. Jupiter is the planet of abundance while Pluto is unrelenting focus, so the combination of the two can be helpful for creating wealth.
If your Jupiter and Pluto make a major aspect to one another, this can be an indicator of wealth at some point in your life. With a sextile or trine, this can come with relative ease, while with a square or opposition, there may be a block to overcome first (though the squares and oppositions may actually be better indicators since their energy is stronger and force you to deal with it in some way, so the sextiles and trines may be less likely to produce wealth).
With a conjunction, it's more in your hands (hey Bill Gates). The closer the aspect is to exact, the stronger it can be. It's especially helpful if Jupiter or Pluto are in or rule the 2nd house (of money); if they aren't, you may achieve wealth through the areas of life ruled by the houses they are located in or rule.
Jupiter-Pluto Midpoint & Wealth
Another spot to look at with these two is their midpoint, which is the exact middle of two astrological points in the Zodiac. Natal planets that are conjunct, square, opposite, semisquare, or sesquiquadrate the Jupiter-Pluto midpoint can also play into wealth. You only use hard aspects for midpoints since they're not actual bodies and hard aspects have more energy with them.
Also assess the sign and house location of the Jupiter-Pluto midpoint as these can show potential ways you can attain wealth.
Jupiter-Pluto Transits & Wealth
Aspects by transit or progressed planets to your natal Jupiter, Pluto, or Jupiter-Pluto midpoint can trigger the energy and provide periods where you have greater opportunity for wealth.
Make sure to track when transit Jupiter aspects your natal Pluto and makes hard aspects to your natal Jupiter-Pluto midpoint; when transit Pluto aspects your natal Jupiter and makes hard aspects to your natal Jupiter-Pluto midpoint; and when progressed planets aspects your natal Jupiter or Pluto or make hard aspects to your natal Jupiter-Pluto midpoint.
