· ComputeLabs Research · from the November 4, 2026 edition

The transaction was reported as completed on November 4. Microsoft’s $25 billion issuance comprised $2 billion of floating-rate bonds and $23 billion of fixed-rate bonds. FinancialJuice separately reported the same aggregate amount and 10-tranche structure.

The fixed-rate securities carried coupons of 4.85%–6.35%. Maturities across the offering ranged from 2028 through 2066, and the named underwriters included JPMorgan, UBS, and Wells Fargo. The supplied report does not map individual coupons or principal amounts to each maturity.

The sources do not specify how Microsoft will allocate the proceeds. They therefore do not establish that the money is earmarked for GPUs, data centers, or other particular capital expenditures. The evidence supplied is Telegram reporting rather than Microsoft’s offering documents, and it provides no collateral or conversion provisions.
