Tether is stepping up its financial transparency efforts as it looks to expand in the US and attract major investors. The company has reportedly brought in KPMG for a full audit, while PwC is helping strengthen internal controls ahead of the review.

This move comes as Tether explores raising up to $20 billion at a massive valuation and pushes forward with new initiatives like a US-based stablecoin. A successful audit could address long-standing concerns around its reserves and regulatory risks.
