Notably, this announcement came a week after Google Play Store’s crypto store wallet app policies.

The backstop here guarantees lease payments tied to TeraWulf’s 10-year agreement dated August 14 with Fluidstack, an AI cloud platform to provide over 200 MW of HPC capacity at its Lake Mariner Campus in Western New York.

In the same part of the deal, Google agreed to the $1.8 billion backstop of Fluidstack’s lease obligations in return for 8% equity stake in TeraWulf before increasing it to $3.2 billion and its pro-equity stake to 14%.

Fluistack also exercised an option to expand the Laker Mariner campus, adding a 160 MW data center building. Notably, in exchange, Google will get the warrants allowing it to purchase more than 73 million WULF shares.

This could make it one of the biggest shareholders of this Bitcoin miner company in the future. Interestingly, at the same time, WULF company has also announced its plan to raise $400M by offering convertible senior notes due after 6 years.
