Weekend Funding Roundup:
May 30-31, 2026
The week that broke the valuation ceiling, the weekend that broke the peace deal. Anthropic secondaries repriced from $640B (Tue) to roughly $1T within 48 hours of the $965B Series H. Saturday Trump asked for changes; Sunday Iran walked. Sunday futures opened red. Brent's -19% May (biggest monthly loss in 6 years) faces a stress test on Monday's open. The big news on deck: Anthropic confidential S-1 expected Monday; SpaceX pricing window opens June 11-12; NFP Friday.
News & Signals
Iran framework MoU UNWINDS over the weekend
Major reversal from Friday's 'mostly agreed' status. Friday May 29 Situation Room ended without a final determination. Saturday: Trump asked for tougher language on Iran's nuclear commitments and Strait of Hormuz reopening; US disabled a ship in the Gulf of Oman with a Hellfire missile. Sunday: An Iranian adviser to the Supreme Leader said 'as predicted, the President of the United States is betraying diplomacy for the third time' and called out 'naval blockade and excessive demands'. Iranian state media reported Tehran would 'completely shut' the Strait of Hormuz over Israeli attacks in Lebanon. Trump said he didn't care if peace talks were over. Hegseth said the US military 'ready to resume combat in the Gulf if needed'. Sunday night futures: Dow -0.3%, S&P -0.2%, Nasdaq -0.2%. The trade that drove Brent down 19% in May was unwinding by Sunday close.
Anthropic secondary repriced from $640B (May 27) to ~$1T within 48 hours of Series H
Forge Global secondary signal: Anthropic common repriced from implied $640B valuation on May 27 to $980B-$1.02T within 48 hours of the Thursday $65B / $965B Series H announcement. Public secondary market is now pricing roughly 4% premium to the $965B primary mark. This is the 'floor not ceiling' data point bulls cite all weekend. Combined with Brad Gerstner / Pauline Yang (Altimeter) public commentary that Anthropic ARR could 'easily triple in 2026' and exit year at $80B-$100B revenue with margins 'exploding higher' (rumored 50-60% gross margins). Anthropic confidential S-1 filing teed up for Monday June 1, beating OpenAI's expected filing 'within weeks' to the punch.
Burry, Malik, and the bubble counter-narrative crystallize
Michael Burry on X (May 27): the SpaceX + OpenAI + Anthropic IPO trio will rival capital raised by 300+ TMT IPOs in 2000. Tech sector weight in S&P could breach 48%, surpassing 1920s, Nifty Fifty, Japan, and dot-com peaks. 'No guarantee Anthropic gets close to $1T... building frontier models is far too expensive... compute could end up more like a commodity.' Om Malik's May 29 essay 'Anthropic, AI and The Numbers Problem' reported being pitched a forward contract for $10M of Anthropic common at $1T mark; called it 'so deep in a bubble that valuations have become absurd.' Highlighted the May 18 transfer-restriction enforcement that voided unapproved secondary sales: forwards on Anthropic common have become a 'sub-asset class with their own price discovery'. The dialectic going into June: is $965B the floor or the ceiling?
All-In weekend episode, ARK weekend filings, and the SpaceX-Anthropic deal
All-In Podcast dropped a Friday episode covering the SpaceX-Anthropic GPU deal (Colossus capacity), 'Elon Web Services', SpaceX IPO valuation, Anthropic growth trajectory, and 'is Anthropic the next great monopoly?'. Cathie Wood / ARK weekend filings showed trimming AMD and adding Cerebras (post-IPO). ARK opening 'backdoor' OpenAI exposure via ETF inclusion of OpenAI shares. Sunday Stratechery and Pirate Wires both reupped on the AI-coding agent compounding (Cognition's $37M to $492M ARR ramp still the canonical chart of the week).
Week-ahead preview: Anthropic S-1, NFP Friday, SpaceX pricing window opens
Monday June 1: ISM Manufacturing, Construction Spending, S&P Global PMI Mfg final; HPE earnings; Anthropic S-1 filing expected. Tuesday June 2: JOLTS; Ulta, PANW, Dollar General earnings. Friday June 5: Nonfarm payrolls, the focus event of the week. SpaceX pricing window opens around June 11-12 targeting $1.75T-$2T valuation, raising up to $80B (largest IPO ever). OpenAI confidential filing expected within weeks. The three-headed mega-cap IPO calendar is no longer hypothetical, it's a June/Q3 reality.
May closes: S&P +5.2%, ninth straight weekly win; Tech SPDR +20%
S&P 500 closed Friday at 7,580.08, +0.22% on the day, ninth straight weekly gain (longest since 2017). S&P May +5.2%, second consecutive positive month. Tech SPDR (XLK) up roughly 20% in May driven by the AI-infra capex thesis crystallizing into multiples. Standouts: Micron +88% in May, Qualcomm +40%, Dell +33% on Friday alone after Q1 beat-and-raise. Nvidia +20% YTD. Dow above 51,000 first time ever (Friday close). Whether May 2026 marks the peak or the breakout is the central question heading into June, and the Iran reversal over the weekend made the question more urgent, not less.
VC Mood on X
Two clean debates dominated the weekend, both on the same number. The first: is $965B the floor or the ceiling for frontier labs? Forge Global secondary repricing from $640B on Tuesday to $980B-$1.02T by Saturday gave the bulls a clean data point that the public secondary market sees $965B as the floor with a roughly 4% premium already built in. Altimeter's Pauline Yang and Brad Gerstner published the math underlying their position: Anthropic ARR could 'easily' triple in 2026 to exit at $80B-$100B revenue, margins exploding higher from a rumored 50-60% gross. The frame: 'Not zero-sum, both Anthropic and OpenAI can be multi-trillion winners.'
The second: is this a bubble? Michael Burry on Tuesday X warned the SpaceX + OpenAI + Anthropic IPO trio could rival capital raised by 300+ TMT IPOs in 2000, with tech weight in S&P potentially breaching 48% past the 1920s, Nifty Fifty, Japan, and dot-com peaks. Om Malik's Friday essay reported being pitched a forward contract for $10M of Anthropic common at a $1T mark, which he called 'so deep in a bubble that valuations have become absurd.' The May 18 transfer-restriction enforcement that voided unapproved secondary sales has turned forwards-on-Anthropic-common into 'a sub-asset class with their own price discovery.' The Burry/Malik counter-narrative now has clean ammunition; the bull side has Forge repricing data.
Under both threads, the Iran framework reversal kept ratcheting risk. Saturday Trump asked for changes; Sunday Tehran formally walked, with Iranian state media talking 'completely shut' Strait of Hormuz. Hegseth said US ready to resume combat. Sunday night futures opened modestly red. Brent's 19% May collapse, the cleanest beneficiary trade of the month, now faces a Monday open with the geopolitical premium back in play. Anduril, Saronic, Hark, and Quartermaster get a fresh tailwind. The IPO calendar gets real Monday with Anthropic S-1; SpaceX pricing window opens June 11-12; OpenAI confidential filing within weeks. Operators come back Monday morning to a tape that has more variables in motion than at any point in May.
