BRUN remains only a small side play, but critics' claims about its customers and crypto revenue are overstated. Anchor customer Thinking Machines raised $2B at a $12B valuation and signed a multibillion-dollar Google Cloud deal, and its $471.7M take-or-pay contract pays in full whether or not the compute is used; the fair concern is concentration, at about a third of backlog. Blockchain rewards fell to about 3% of revenue in Q1 2026 as lease revenue ramps. A big lock-up expiry hits Monday. x.com  … Show more

Boost Run's delivery ahead of schedule and ability to capture higher current compute pricing strengthen its upside case. A release this week shows faster delivery, while management says it will not dilute with equity; guidance could imply $2B ARR exiting 2027. Unlike CoreWeave, it is not locked into stale contract terms. Short interest is 26%, even as the shares are down 75% from their highs and fundamentals improve. x.com 

BRUN is not a buy right before its insider lock-up could expire. Per @saso_capital, the lock-up ends once BRUN closes at or above $12 on 20 of 30 trading days; with every close since its May 11 listing well above that, the earliest release is June 8, 2026. Insiders holding about 54M shares, including CEO Andrew Karos's 29.5M Class B shares, would then be free to sell. x.com  x.com 

SpaceX's exclusive use of Nvidia GPUs and other supply constraints make Musk's 13-20 GW operational compute forecast for end-2027 too high. A substantial buildout is still incredibly enticing, but reaching that scale likely requires cheap capacity from struggling neoclouds, mostly through capacity deals and some acquisitions. Its attractive $40B off-balance-sheet GPU lease deal is only a drop in the bucket of the debt needed. Capacity can still grow quickly over time. x.com  x.com  x.com  x.com  … Show more

Nvidia's shares remain pressured because neoclouds have yet to show demand revenue can cover debt service even at higher rates. CoreWeave and Nebius are dragging the shares, though that concern is being priced in and digested. Reuters reports ByteDance, Alibaba and Tencent ordered $35B in Nvidia chips; Elon Musk says SpaceX is on track to bring roughly 200,000 GB300 GPUs online per month through end-2026. Nvidia made a higher low, and the next higher-high target is $256. x.com  x.com  x.com  x.com 

Boost Run faces a huge share unlock on Monday, when 90% of locked-up shares can be released. Per the S-4, 10% of each seller's shares were never locked, and the remaining 90% unlock early once the stock closes at or above $12 for 20 of 30 trading days. The sponsor's insider letter separately frees 10% of founder shares at closing, which only makes sense if the price trigger releases everything else. Holders may not sell, but they will be able to. x.com  x.com  x.com 

CoreWeave's leveraged GPU rentals make its financing loop vulnerable to higher rates or a slipped contract. Despite $2.5B+ quarterly revenue and $104B backlog, debt is $21-25B with up to $68B in potential future obligations, $35-39B planned 2026 capex and -$4.7B free cash flow last quarter. Nvidia's $2B equity investment funds purchases of Nvidia chips, and Nvidia backstops $6.3B of unsold capacity through 2032. Demand is pulled forward with debt; either trigger unwinds the loop. x.com 

Contracted AI compute demand makes four AI infrastructure stocks worth buying at 52-week lows. Applied Digital has a $36B backlog and expects 600+ MW online within 12 months; Cipher Mining has $8.5B+ in AI leases with payments ramping; CleanSpark has a 20-year $6.6B lease and 1.8+ GW power portfolio; CoreWeave has a $104B backlog and raised its year-end ARR target to $18.5-19.5B. x.com  x.com 

Boost Run's lock-up expires within days, letting insiders and the CEO sell their shares, which could cause massive selling pressure. That is a big deal and a huge risk against the earlier bull case for the newly listed AI infrastructure provider, built on Nvidia Preferred Cloud Service Provider status, a $1.44B Dell purchase agreement and about $471.7M of take-or-pay contracts for 5,000 Nvidia B300 GPUs. x.com  x.com 

CoreWeave keeps winning the next GPU allocation as the scaled independent cloud that gets the first racks of each new Nvidia generation. With hyperscalers feeding their own models first and Nebius still scaling, it holds $104B of contracted backlog; latest-quarter revenue grew 112% at a 67% gross margin, at 12.6x EV/sales. The risk is that its top two customers were 65% of Q1 revenue under 'up to' contracts and heavy debt funds the build, so backlog must become cash before debt comes due. x.com
