2026-10-26 — Anthropic’s S-1 lists about $3.1 billion a month to SpaceX for Nvidia GPU capacity

• The Verge reported that Anthropic’s S-1 details compute commitments of roughly $3.1 billion a month to SpaceX for access to Nvidia GPUs once all planned capacity is delivered, totaling as much as $120.5 billion by 2029 — The Verge’s passage does not say which SpaceX sites supply the capacity.

2026-09-25 — Justice Department asks to pause the NAACP’s Clean Air Act suit over SpaceXAI’s Southaven turbines

• The Justice Department asked a federal judge Friday to pause the NAACP’s Clean Air Act suit against SpaceXAI over its unpermitted gas turbines in Southaven, Mississippi, while its appeal of the judge’s refusal to let it intervene is decided The department moved in June to intervene for the EPA and have the suit dismissed, arguing SpaceXAI’s importance to national security; the judge did not allow it, and the department appealed to the Fifth Circuit on September 18.

2026-09-18 — The Justice Department appeals to the Fifth Circuit to join the NAACP’s Clean Air Act suit over xAI’s Southaven turbines

• The Justice Department filed a notice of appeal to the Fifth Circuit on 09-18 in an effort to intervene in the NAACP’s Clean Air Act case against xAI’s unpermitted gas turbines at Southaven, Mississippi, arguing the district court’s failure to rule in time on its request to join amounted to an “effective denial.” The suit, brought by the NAACP through Earthjustice and the Southern Environmental Law Center, targets the power plant that runs Colossus 2 across the state line in Memphis; DOJ first signaled in May that it might step in, then asked the court in June to dismiss the case, citing what it called the government’s “priorities with respect to promotion of artificial intelligence.” Taking the intervention fight to the appeals court moves the federal shield already on this thread (the July “national security” framing) from a district-court motion into a higher-court test.

2026-09-17 — Family sues SpaceXAI for $30M over a fatal first-day fall at Colossus II

• The family of a contract worker who died after falling roughly 25-30 feet from an unguarded mezzanine on his first day at SpaceXAI’s Colossus II (Whitehaven) data-center campus filed a $30 million wrongful-death lawsuit. The worker, Alexis Vicent, fell in August 2025 and died the following February; the suit — moved to federal court — alleges the mezzanine had no tie-off point, guardrails, safety nets or adequate warnings, and Tennessee’s OSHA had already cited the site for exposing workers to fall hazards. This is separate from the air-pollution/NAACP legal action already tracked on this thread — a labor-safety liability angle on the Colossus buildout rather than an environmental one. (Daily Memphian)

2026-09-11 — Memphis residents confront xAI over $3.2m in promised Community Benefits Fund money that still hasn’t arrived

• A Westwood/Boxtown community meeting on the xAI Community Benefits Fund broke up early amid shouting after residents demanded to know why $3.2m in xAI property-tax revenue earmarked for the 38109 ZIP code — Boxtown, Westwood and Whitehaven, the neighborhoods closest to Colossus — still hasn’t reached them. The fund is real money tied directly to Colossus’s own tax bill: 25% of FY26 property-tax revenue from the facility, created by a Memphis City Council ordinance, with roughly $1.4m planned for home-repair/weatherization forgivable loans and $500k for a paid cleanup workforce. This is the first instance on this thread of the host-community relationship souring over money already committed rather than over turbines, permits or power — a different kind of friction than the gas-plant fight this thread has tracked since August. (Fox13 Memphis)

2026-08-24 — xAI tells a Mississippi court that cutting its gas-plant power would make Grok “largely cease to function”

• A hearing scheduled for 2026-08-24 to decide whether to shut down xAI’s unpermitted Southaven, Mississippi gas turbines was postponed, but xAI’s own court filing opposing the shutdown states an abrupt power loss “would inflict catastrophic harms on Defendants and hundreds of millions of users worldwide: Grok would largely cease to function, and other cutting-edge AI services would be significantly disrupted.” The underlying suit is the NAACP/Southern Environmental Law Center injunction (amended after discovery found ~30 more turbines than initially disclosed at the site). This is the sharpest primary-source statement yet, in xAI’s own words, on how tightly Grok’s availability is coupled to the power/permit fight this thread exists to track — a direct answer to whether “owning the mines” is actually load-bearing or a liability. ⚠️ Hearing date postponed; no new date confirmed. (Yahoo News, AOL)

2026-08-18 — Memphis council takes a first vote to freeze new data-center permits, xAI’s existing sites exempted

• The Memphis City Council passed, on a first-reading voice vote 2026-08-18, a temporary moratorium pausing zoning/land-use/building permits for NEW data centers while the city studies infrastructure, utility, energy, water, noise and environmental impacts — a second and third reading by the 13-member council are still required before enactment. The ordinance explicitly does not apply to xAI’s existing Colossus sites; sponsor J.B. Smiley Jr. said he proposed it after learning via social media that xAI is already building a fourth data center on land it already owns. The Greater Memphis Chamber asked the council to vote no, warning it would hurt the city’s competitiveness. This is the local-permit escalation this thread tracks, one step short of actually constraining the site itself. (Yahoo News, Memphis Flyer)

2026-08-15 — Congress presses on the turbines as a fourth data center is confirmed

• A House Energy and Commerce Committee ranking member demanded SpaceXAI turn over records and open Colossus 1/2 to site tours — Rep. Frank Pallone (D-NJ) wrote CEO Elon Musk saying the unpermitted gas turbines created “a massive health risk,” requesting a full turbine list, internal communications, and emissions/power/water documentation by Aug 11. (CNBC)
• Musk confirmed a fourth Memphis-area data center (“Minihard”), sited next to Colossus 2 and Macroharder, to run 220,000 GB300 GPUs in a denser configuration than the existing sites — while SpaceXAI began removing the 69 unpermitted turbines at the Southaven (Colossus 2) site, to be replaced by a permanent 1.2GW, 41-turbine power plant; removal starts in August and is expected to run through July 2027, so the permit fight resolves on a multi-year clock, not immediately. (Data Center Dynamics)

2026-07-24 — Opened + crawled

• Thread opened — answering the SpaceXAI Q1 gap the board’s dormant posture exposed.
• The “owns its mines” thesis holds and then some. Compute ownership is real, frontier-relevant (Grok 4 was trained on Colossus), and now so large that SpaceX leases the older Colossus 1 to Anthropic while training Grok on Colossus 2 — ownership became a revenue lever, not just a cost center. The binding constraints are power and permits, not silicon.

2026-07-15 — The permit fight escalates

• xAI ran ~59 gas turbines (57 in Southaven) for Colossus 2 without federal Clean Air permits; DOJ (Trump admin) moved to shield them as a “national security” asset — a novel federal-cover angle. (technology.org)

2026-05-06 — Ownership becomes a revenue lever

• Anthropic rents ALL of Colossus 1 (220k GPUs, 300+ MW) for $1.25B/ month through May 2029 ($40B+) — with a side-clause to explore orbital compute. SpaceXAI trains Grok on Colossus 2 while leasing the older cluster; cross-refs Circular Financing (Anthropic, which “rents its mines”, now rents from SpaceX too). (CNBC)

2026-04-14 — The environmental-justice suit

• NAACP / SELC / Earthjustice filed a Clean Air Act suit over 27 unpermitted turbines at Colossus 2 (~$124k/day penalties sought); the plant could emit >1,700 tons NOx/yr — the largest NOx source in metro Memphis, in majority-Black tracts at the 95th–99th EJScreen percentile. (Earthjustice)

2026-02-02 — Absorbed into SpaceX

• SpaceX absorbed xAI (which already held X) at $1.25T combined ($1T SpaceX + $250B xAI) — the largest merger ever; SpaceX cash flow now underwrites the data-center burn. (Corrects our earlier “~$2.1T” figure — see Musk Megacap.) (Bloomberg)

2025-07-09 — The payoff datapoint

• Grok 4 released, trained on Colossus (200k GPUs) — first model to hit 50% on Humanity’s Last Exam, genuinely frontier at launch. The proof that owning the mines produced a frontier model at least once. (x.ai)

2024-09 → 2025-05 — The buildout

• Colossus online: 100k H100 in 122 days (Sept 2024), doubled to 200k ~92 days later; fully operational at 200k GPUs by May 2025 (150 MW grid via MLGW+TVA + 150 MW Tesla Megapack backup), then ~230k (150k H100 + 50k H200 + 30k GB200) by Dec 2025. (Tom’s Hardware)

Scale, honestly — confirmed vs. reported

• Confirmed floor: ~230k GPUs operational (Colossus 1), ~250 MW draw — now leased to Anthropic, not running Grok.
• Reported ceiling: the widely-cited ~555k GPUs / ~2 GW / ~$18B headline is analyst-derived (SemiAnalysis), NOT an xAI disclosure — it bundles Colossus 1 + the ramping Colossus 2 and mixes live with target. Treat as direction of travel, not a live count. The 1M-GPU plan is Musk’s roadmap, reported not delivered.
