Lead story · REIT M&A
Equity Residential and AvalonBay strike a $69 billion apartment tie-up.
If it closes, the combined entity is the largest publicly-traded residential landlord in the US — visible to MARS across three tables at once.
The May 21 announcement is a rare all-cash mega-cap REIT merger, and MARS is carrying it three ways: as a merger_deals_v2 row on both sides of the join, as an real_estate_deals_v2 row under the reit vertical, and as a residual on schedule_13g_v2 where institutional holders started re-filing positions within 48 hours.
Equity Residential (CIK 906107) had never made an acquisition of this size; AvalonBay (CIK 915912) had never been the target of one. Neither had appeared as an M&A counterparty in merger_deals_v2 in the twelve months prior. Both are covered by our full SEC substrate: 10-K annual filings on the read side, Form 144 insider filings on both, and — post-announcement — a wave of Form 4 activity we'll surface in a later issue once that pipeline lands.
What makes the deal noteworthy for the newsletter's beat isn't the price. It's what happens next in the substrate: as filers begin declaring positions on the merged entity, we'll see the same institutional names show up in investors_v2 that we've been ADV-enriching all quarter. If that crd-linked graph lights up cleanly, we have the ownership picture without a single manual data entry.
Sources: mars.merger_deals_v2, mars.real_estate_deals_v2, mars.schedule_13g_v2. Filed under acquirer company_id = Equity Residential; joined to AvalonBay via target_company_id. Value reported by acquirer at signing.

This week in private rounds
The AI capital story continues, but the fintech and infra breadcrumbs are quieter and more interesting.
06 JUN 2026 · Debt Facility · AI
$35 B · Anthropic pulls a credit facility led by Apollo and Blackstone
Not a valuation round — a debt line, structured against future contract revenue. Both lenders are ADV-enriched in investors_v2 with CRD, RAUM, and disciplinary flags on file.
— from mars.funding_deals_v2 · investors resolved via deal_investors_v2 bridge
17 JUN 2026 · Form D · Fintech
$868 M · Ramp files Form D signalling a fresh growth round
Amount sold: $782 M of $868 M offered. Filed to SEC, not press-released — the substrate saw it before the news feeds. Ramp's earlier public reporting put a $30 B valuation on the round; this filing anchors the size.
— from mars.form_d_filings_v2. Cross-linked to funding_deals_v2 via CIK.
30 JUN 2026 · Form D · AI infra
$1.5 B · Baseten files a mega Form D as GPU-inference demand curves up
Amount sold: $1.1 B against a $1.5 B offering — likely still open. Baseten is a serving layer for open-weights models. Compare against the CoreWeave pre-IPO Form Ds (see this weekend's two-workup companion): same shape, roughly two years behind.

~$3 B · Anthropic takes strategic capital from Salesforce
Salesforce enters as a strategic investor via the customer-partnership route — a category of round MARS canonicalizes but that few consumer sources classify cleanly. The gross size reported in one article was noisier than our extractor could resolve; we've held the exact figure in warn tier while the audit pass reconciles.

M&A momentum
Six billion-plus M&A announcements in the window; three are pure-private targets.
22 JUN 2026 · Biotech
$10.9 B · AbbVie to acquire Apogee Therapeutics
Immunology-adjacent tuck-in; both counterparties resolved cleanly. Advisor bridge already populated on both sides.
— from mars.merger_deals_v2 · mars.merger_advisors_v2
09 JUN 2026 · Biotech
$10.6 B · GSK acquires Nuvalent
Oncology-focused. The Grok-web tier chain resolved the near-duplicate "GlaxoSmithKline (GSK)" vs "GSK" acquirer name to one company_id, and merged the two article rows into a single canonical deal.

22 MAY 2026 · Consumer / Pharma
$12.4 B · CVC + GBL consortium takes Recordati private
Italian specialty pharma, EU deal, dual-consortium acquirer. MARS carries this via both consortium members in the acquirer text; deduplication runs at Phase G.

$12.3 B · EQT AB takes Intertek private
EQT's second public-to-private this month. EQT itself is enriched via ADV on the investors side.

Reit alley
The reit vertical is 48 hours old and already catching billion-dollar deals. Some big enough to raise our own eyebrows — see also section 05.
03 JUN 2026 · Industrial
$81 B · Blackstone reported as buyer on a massive industrial portfolio
Largest reit-side row of the window. See extraction watch below — the number is under range-sanity review, but the deal itself is real (Blackstone Real Estate did announce a large industrial platform buy in early June).
— from mars.real_estate_deals_v2 · reit vertical
12 JUN 2026 · Data centers
$10 B · AWS closes on a data-center property acquisition
Data-center inventory is the hottest sub-asset class in the substrate. Between AWS, Blackstone, and Blue Owl this window alone, over $45 B tracked.
— from mars.real_estate_deals_v2
02 JUL 2026 · Fund raise · Data centers
$10 B · Starwood Capital closes a data-center-dedicated fund
A pure fund raise, not a specific property. Reit vertical carries both shapes in one table via deal_type partitioning.
— from mars.real_estate_deals_v2
30 JUN 2026 · Fund raise · Data centers
$9 B · Blue Owl Credit Income Corp fund raise
Blue Owl's data-center thesis continues to attract capital. Same firm shows up in the ADV-enriched investors_v2 when it participates in credit deals.

SEC signals worth watching
Filings the SEC pipeline surfaced before the news feeds did.
17 JUN 2026 · Form D · Real estate
$2.0 B · Roers Multifamily Income REIT files Form D
Private REIT accumulation vehicle. No press release. Watching for a follow-on that suggests they've deployed into a specific portfolio.
— from mars.form_d_filings_v2
02 JUL 2026 · Form D · Industrial RE
$750 M · Sealy Industrial Partners IV files a $441 M sold-to-date
Industrial-real-estate LP, offering still open. The kind of substrate that doesn't hit consumer sources but is exactly the shape MARS's SEC pipeline captures.
— from mars.form_d_filings_v2
17 JUN 2026 · Form D · Public issuer
$1.0 B · Howard Hughes Holdings files a full-sold Form D
Ticker HHH. Fully-subscribed offering — cross-linked to their broader deal history in funding_deals_v2.
— from mars.form_d_filings_v2
25 JUN 2026 · Form D · Insurance
$975 M · Prime Special Risk Holding Company files a Form D
Just $2 M sold against $975 M offered — brand-new offering, first row of a Series. Watch this one over the next 90 days for follow-on filings.

Extraction watch
Big numbers we're not confident about. The integrity gate quarantines them; the reader should know they exist.
16 JUN 2026 · under review
$60 B · SpaceX "acquires" Cursor / Anysphere
The extractor pulled these two names off a co-appearance in headline text; the deal shape is not consistent with either firm's known activity. Held for Grok-web verification.
— mars.merger_deals_v2 · integrity_tier='warn'
30 JUN 2026 · unit review
$65 B · Anthropic "Venture Round"
Almost certainly the extractor read the round's valuation as its size. Same pattern we caught for Tilray earlier this week on the funding side. Quarantined; the audit sweep will re-classify.
— mars.funding_deals_v2 · integrity_tier='warn'
03 JUN 2026 · size review
$81 B · Blackstone industrial acquisition
Blackstone did announce a major industrial platform buy in early June, but the reported enterprise value in reliable sources is closer to $10 B. The extractor read the announcement text at face; the reit team's range-sanity guard is queued.
— mars.real_estate_deals_v2 · integrity_tier='warn'
05 JUN 2026 · under review
$150 B · Resorts World Cirrus multifamily acquisition
Casino operator listed as a multifamily buyer at $150 B. Every part of that shape is suspect. In the queue for the Haiku audit.

How this is made. Every row above came from a SQL query against the MARS v2 substrate — funding_deals, merger_deals, real_estate_deals, form_d_filings, schedule_13g. No editorial cherry-picking beyond the shortlist of largest-and-most-notable in a 45-day window. The Extraction Watch section is what the integrity_tier='warn' quarantine caught; publishing it is the whole point.
Cadence. If this format holds up, it'll go out weekly. Filings that land in the middle of the week get carried into the following issue.
Companion. A per-company version of this substrate — three companies shown against every table — is here.
