No longer a private company

xAI has exited the private market — see the notice above for the public ticker or acquisition terms. Our 4-method private valuation no longer applies, so we don't show a secondary-market estimate here. The funding history and data below remain for reference.

Confidence breakdown

Historical private-market model output — shown for reference only. This company has exited the private market; the 4-method estimate below no longer represents current market value.

The numbers below reflect what our private-market model would have estimated before the exit event. They are shown for historical context only and should not be used as current equity values.

Method A — Peer-multiple

weight 25%suppressed23% confidence

↳ Effectively excluded from the blend — this method is structurally unreliable for this company.

Growth-weighted peer EV/Revenue: 47.2x → 18% private-company discount → 38.7x on $500M revenue. Output implies less than half the recent market anchor ($250B) — this company is likely valued on optionality / non-revenue factors and Method A is structurally less reliable here.

Method B — Secondary-implied

weight 45%suppressed25% confidence

↳ Effectively excluded from the blend — this method is structurally unreliable for this company.

No verified secondary market data available — estimate relies on primary round, peer multiples, and sector momentum.

Method C — Primary time-decay

weight 20%→ $434.8B77% confidence

$250B round (2026-02-02) × 1.78× growth × 0.98× multiple decay over 0.4 years

Method D — Sector momentum

weight 10%→ $280.5B54% confidence

$250B × (1 + 32% p.j.)^0.4yr = $280.5B via BOTZ ETF-proxy

Overall confidence

34%

Weighted average of the four methods. Above 60% is high, 35–60% medium, below 35% low.

Private-market scenarios disabled

This company is no longer private. Private-market scenario modelling does not apply. Use public filings, broker statements, or exchange data for current equity value.

Transparent assumptions

What we assumed where exact data isn't available. If any of these don't match your situation, the numbers above will be off.

Fully-diluted share count

353.125M shares

We don't have authoritative cap-table access for private companies. The number above is reconstructed from SEC Form D filings, secondary-market price-vs-valuation math, and leaked share-class summaries. Actual fully-diluted count (including unvested option pool and SAFEs) may differ by 5–15%.

Common-stock waterfall

1.0× to common

We assume a clean common-stock outcome — i.e. preferred-share liquidation preferences and ratchets do not extract value before common. In a down-exit, this assumption can be very wrong: preferred stack can take 30–70% of proceeds.

Private-company illiquidity discount

18% off public peers

Applied to Method A (peer-multiple). Per-company because category leaders with deep secondary markets and a clear IPO path warrant a smaller discount than early-stage names. The literature range is 10–35%; for xAI we use 18% based on secondary-market depth, valuation history, and proximity to liquidity.

Revenue growth assumption (Method C)

300% YoY

Compounded forward from the last primary date to today to estimate the company's value drift. Set per-company based on disclosed or reported ARR trajectory. Method C is further capped at 1.3× the most recent secondary trade (if any) to stop runaway extrapolation when revenue growth outpaces what the market is actually paying.

Sector ETF momentum (Method D)

BOTZ @ 32%/year

Method D applies the trailing return of BOTZ as a market-proxy adjustment to the primary valuation. Crude — meant as a tiebreaker when peer and secondary data conflict, not as a primary signal.

Outlier auto-downweight

Methods >50% from median get ½ weight

Robust-statistics safety net: any method whose output strays more than 50% from the median of the other three methods has its confidence weight halved when computing the blended mid-point. Prevents a single bad extrapolation from dragging the headline.

Recency decay for secondary trades

180-day half-life (e⁻ᵈ/¹⁸⁰)

A trade from 30 days ago counts ~5× more than one from 180 days ago. Tunable; some platforms use shorter half-lives.

Tax estimate

US federal only, single filer

Uses 2024 US federal brackets, ignoring state tax, NIIT, AMT credit recovery, and any other deductions. Treat as a directional sanity check, not a tax bill.
