Reuters reported that Astra Space is seeking to raise $250m at a $1bn valuation, in a round expected to close in the same quarter, to fund Rocket 4 development and expand satellite propulsion work for defence missions. The company was taken private in 2024 and has not launched since the Rocket 3 series.
On 10 August 2026 Alphabet closed an underwritten public offering of $25 billion of US dollar-denominated senior notes off its June 2026 Form S-3 shelf (File No. 333-296395), under the February 2016 BNY Mellon indenture. Ten tranches were issued: $750m floating rate due 2028, $1.25bn 4.500% due 2028, $500m floating rate due 2029, $2.0bn 4.625% due 2029, $3.5bn 4.875% due 2031, $2.5bn 5.200% due 2033, $4.5bn 5.450% due 2036, $3.0bn 6.250% due 2046, $4.5bn 6.375% due 2056 and $2.5bn 6.500% due 2066. Coupons of 6.25-6.50% at the long end are notably high for an AA-rated issuer and show the price of raising this much duration at once. Combined with the May euro, Canadian dollar and yen offerings (roughly $21bn) and the June $49.6bn net equity and mandatory convertible raise, Alphabet has taken in well over $95bn of external capital in four months, against a $40bn at-the-market equity programme still undrawn - the clearest single measure of what frontier AI infrastructure now costs.
CFS announced (Jul 30) $1B in new equity, bringing total raised to ~$4B and roughly 30% of all private fusion investment globally — its largest single round since the $1.8B Series B in 2021. Notably the backers are pension funds, sovereign wealth funds and infrastructure investors, a first for the fusion industry, signalling a shift toward treating fusion as an infrastructure-grade bet. Proceeds de-risk ARC-specific systems and prep the first commercial site; SPARC is ~80% assembled with first plasma/net energy gain targeted for 2027.
Lowercarbon Capital joined Focused Energy's Series A financing round, adding to the $240 million raised in May 2026. Focused Energy describes the round as the largest fully secured Series A in the global fusion industry.
RLWRLD raised $26 million in Seed 2 funding, bringing total seed funding to $41 million, to expand into North America and accelerate proof-of-concept projects.
On 11 June 2026 CFS announced that Plynth Energy, an Abu Dhabi government-owned early-stage fund founded in 2024 to focus on fusion technologies and fusion supply-chain expansion, had acquired a minority stake in the company. No investment amount, valuation or ownership percentage was disclosed, and the release stated only that both parties would explore future collaboration. The significance is the investor class rather than the size: a sovereign-owned fund entering the cap table seven weeks before CFS closed a $1B round that it described as the first fusion round led by pension and sovereign funds.
Apollo Global and Blackstone, partnering with Broadcom, launched an AI infrastructure platform with an initial $35B to expand Anthropic's compute capacity using Broadcom custom chips across five US sites; Google is backstopping lease payments. Materially scales Anthropic's compute ahead of its expected IPO.

In the first week of June 2026 Alphabet did something it had never needed to do at scale: it sold equity. On 1 June it filed a new Form S-3 shelf (Reg. No. 333-296395) and entered an equity distribution agreement with Goldman Sachs, J.P. Morgan and Morgan Stanley to sell up to $40.0 billion of Class A and Class C stock through an at-the-market programme, at commissions of up to 0.5% of gross proceeds, with no obligation to sell. On 2 June it agreed to issue 167,500,000 Series A and 167,500,000 Series B depositary shares, each representing a 1/20th interest in a share of 6.25% mandatory convertible preferred stock with a $1,000 liquidation preference; underwriters exercised over-allotment options of 25,000,000 depositary shares per series in full on 3 June, and both offerings closed on 5 June. Alphabet's own Q2 2026 disclosure states that the Class C stock and mandatory convertible preferred offerings raised aggregate net proceeds of $49.6 billion, for general corporate purposes 'including capital expenditures to scale AI infrastructure and global compute'. For a company that generated $64.4bn of trailing-twelve-month free cash flow and carried a large net cash position, issuing equity-linked paper at a 6.25% coupon is a structural change in how the AI buildout is financed, not a routine treasury exercise.
Helion Energy announced a $465 million Series G round led by Thrive Capital at a $15.5 billion post-money valuation on June 4, 2026, bringing total capital raised to over $1B. The Sam Altman-backed fusion startup is building a fusion power plant to supply Microsoft. This is a major funding event materially raising Helion's war chest and valuation.
