The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
It is an acidic magma and has a huge caldera.
The Yellowstone caldera is a supervolcano located in Yellowstone National Park. While it is an active volcanic system, there is no current indication that it is about to erupt. The USGS monitors Yellowstone closely, and any signs of increased volcanic activity would be detected well in advance.
The heat for Yellowstone's geysers comes from magma beneath the Earth's surface. This magma heats up the water in underground reservoirs, creating pockets of steam that eventually erupt through geysers.
The world's largest known magma chamber is located beneath Yellowstone National Park in Wyoming, USA. This massive chamber fuels the park's geothermal activity and is responsible for the park's famous geysers and hot springs.
Volcanic features like those in Hawaii and Yellowstone are associated with hotspots, which are areas where magma rises to the Earth's surface from deep within the mantle. The magma creates volcanoes, geysers, and other geothermal features in these regions.

The magma in the earth had to go somewhere and it has accumulated around the Yellowstone area for many thousands of years.

Yellowstone's last magma eruption was about 70,000 years ago. The last super eruption was approximately 640,000 years ago.
A few miles under Yellowstone is an enormous magma chamber associated with a supervolcano.
