CoreWeave (CRWV) secured an $8.5 billion financing round with a credit rating upgrade to A3 from B, reflecting stronger asset quality as inventory depreciation is slower than previously modeled, while full-year 2025 revenue hit $5.131 billion (up 168% YoY) backed by a $66.8 billion backlog anchored by $22.4 billion in OpenAI commitments and $14.2 billion from Meta. Corning (GLW) is benefiting from the fiber-over-copper trend in AI infrastructure, with its Optical Communications segment generating $1.70 billion in Q4 revenue (up 24% YoY).

CoreWeave’s improved credit terms and larger backlog reduce the cost of scaling a business model that requires immense capital expenditures and currently operates with negative free cash flow.

A recent study identified one single habit that doubled Americans’ retirement savings and moved retirement from dream, to reality. Read more here.

CoreWeave (NASDAQ:CRWV) grabbed the spotlight on CNBC's Stop Trading Tuesday morning, with Jim Cramer calling the company's latest financing round a genuine watershed moment for AI infrastructure. "My god, there's so much happening this morning with the landmark $8.5 billion financing, obviously, for the great data center builder," Cramer said, flagging the deal as something investors in the AI buildout need to pay attention to.

The Credit Rating Upgrade Changes the Calculus

The financing itself is notable, but the credit rating story behind it is what makes this deal structurally significant. CoreWeave received an A3 credit rating on the deal, up from a B rating previously, a multi-notch jump that signals a fundamental reassessment of the company's asset quality. Cramer pointed to the reasoning: the inventory is worth more than previously thought and depreciates slower than assumed, which drove the upgrade. For a company carrying total liabilities of $45.967 billion against total assets of $49.302 billion, better credit terms on new debt materially reduce the cost of growth.

That matters because CoreWeave's capital requirements are immense. The company spent $10.309 billion in capital expenditures in 2025 and generated free cash flow of -$7.251 billion for the year. Interest expense alone hit $388 million in Q4 2025. Cheaper financing at investment-grade-adjacent rates is the lever that makes the model more sustainable as the company scales toward its $66.8 billion revenue backlog.

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

The underlying business momentum supports the upgraded view. Full-year 2025 revenue hit $5.131 billion, up 168% year over year, making CoreWeave, in CEO Michael Intrator's words, "the fastest cloud in history to reach $5 billion in annual revenue." The backlog grew more than 4x during 2025, anchored by commitments from OpenAI (total commitments of $22.4 billion) and Meta (up to $14.2 billion).

The stock is trading at $72.95 as of Tuesday morning, up 6% on the day after a rough stretch that saw shares fall -16% over the prior week. The financing announcement appears to be providing a near-term floor.

The Broader AI Infrastructure Picture

Cramer also flagged Corning (NYSE:GLW) in the same breath, noting that Jensen Huang's deal is a win for fiber, not copper — a distinction that plays directly into Corning's optical communications strength. Corning's Optical Communications segment generated $1.70 billion in Q4 revenue, up 24% year over year, and the company carries a $130 analyst consensus price target with 11 buy or strong-buy ratings. Separately, Cramer noted Palo Alto Networks (NASDAQ:PANW) CEO Nikesh Arora's $10 million open market stock purchase — a conviction signal worth watching given the stock's -16% year-to-date pullback and analyst consensus target of $206.97.

Data Shows One Habit Doubles American’s Savings And Boosts Retirement

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.

And no, it’s got nothing to do with increasing your income, savings, clipping coupons, or even cutting back on your lifestyle. It’s much more straightforward (and powerful) than any of that. Frankly, it’s shocking more people don’t adopt the habit given how easy it is.
