SpaceX Jumps 11% On Musk's AI Revenue Forecast

SPCX closed at $146.21 on August 12, 2026, up 9.69% from the prior close of $133.29.

Executive Summary

SPCX gained sharply on Wednesday, closing at $146.21 versus Tuesday's $133.29 close, a 9.69% move that pushed shares back above the $135 IPO offer price. According to Benzinga, a "key trading signal" flashed at $138.39 during the session, after which shares extended their intraday advance. The Motley Fool attributed the broader move to CEO Elon Musk's comments that AI revenue could exceed all of SpaceX's other business lines by September, tied to compute-leasing arrangements with Anthropic and Google. Benzinga also reported Musk telling employees that Starlink has crossed 13 million consumer subscribers and 22 million monthly Starlink Mobile users, and noted a newly disclosed $1.22 billion investment from Norway's sovereign wealth fund.

Coverage of the move was not uniformly bullish. The Motley Fool ran two separate pieces questioning the rally's durability: one arguing the stock's post-IPO slump could still have further to run based on historical patterns for hot IPO pullbacks, and another flagging a second insider share-unlock event on August 21 (roughly 319 million additional shares) as a source of coming selling pressure. A third Motley Fool piece rated SpaceX an "avoid" among hyperscaler names, citing a roughly 39x forward price-to-sales ratio. Investors weighing today's bounce should read it alongside those valuation and float-expansion concerns rather than in isolation.

SpaceX's stock has fallen from its IPO peak of $211.39 to around $140, returning to its $135 debut price. The company's $2.64 trillion peak valuation (141x revenue) proved unsustainable as investors grew concerned about steep losses, aggressive spending, and the xAI acquisition.

Price Action

Metric	Value
Open	$135.03
High	$149.60
Low	$134.01
Close	$146.21
Change vs prior close	+9.69% (prior close $133.29)
Volume	155,465,098
Intraday range	$134.01 – $149.60 ($15.59)
Close vs IPO	+8.30% vs IPO offer price ($135.00); -9.16% vs IPO-day close ($160.95)

SPCX opened at $135.03, essentially at the $135.00 IPO offer price, dipped modestly to an intraday low of $134.01, then ran to a high of $149.60 before settling at $146.21. Volume of 155.5 million shares ran about 1.24 times the average volume to date (108.8 million), and roughly 43% above the prior session's 109.0 million shares, indicating the move was accompanied by a genuine pickup in participation rather than thin trading. The close held well above both the opening print and the prior close, while remaining short of the intraday high.

The one-line takeaway: SPCX reclaimed the $135 IPO offer price on above-average volume, but the close near $146 still sits roughly 9% below the first-day close of $160.95.

Technicals

SPCX has only been trading for about two months, so longer-horizon technicals still carry limited weight: SMA-50 and SMA-200 are not yet available given the short trading history. Shorter-window measures are computable at this point and are used below, but should still be read with the caveat that the underlying sample remains small.

Trend

The short-term moving averages point higher: SMA-5 sits at $133.25 and EMA-5 at $134.66, both below today's close of $146.21, while SMA-10 ($123.50) and SMA-20 ($121.22) sit further below still. That ordering — price above the shorter averages, which are in turn above the longer ones — reflects the sharp bounce over the past several sessions off the early-August lows visible in the close history (a trough near $108.27 on August 5, followed by gains to $114.92, $133.11, $138.74, a pullback to $133.29, and today's $146.21).

Candle read

Today's candle had a body of $11.18 within a $15.59 total range, with a $3.39 upper wick and a $1.02 lower wick. The close-location value of 0.78 means the close sat about 78% of the way up the day's range — well above the midpoint and close to the high. The small lower wick shows sellers made little headway pushing the stock back toward the open, while the larger upper wick shows some resistance was met before the close, consistent with a strong but not maximally bullish (full-range) session.

Support levels

• $134.01 — today's intraday low
• $133.29 — prior session's close
• $133.25 / $134.66 — SMA-5 / EMA-5
• $135.00 — IPO offer price, a round-number level the stock reclaimed today
• $123.50 — SMA-10
• $121.22 — SMA-20

Resistance levels

• $149.60 — today's intraday high
• $150.00 — nearest round number above the day's high
• $160.95 — the IPO-day close

Momentum interpretation

Bull scenario: SPCX holds above the $135.00 IPO offer price and the $133.25–$134.66 SMA-5/EMA-5 zone, then clears today's $149.60 high and the $150 round number, opening a path back toward the IPO-day close of $160.95.

Bear scenario: SPCX loses the $134.01 intraday low and $133.29 prior close, unwinding today's gain back toward the SMA-10 ($123.50) and SMA-20 ($121.22) zone.

Neutral scenario: SPCX consolidates within today's $134.01–$149.60 range as the market digests the AI-revenue commentary against the valuation and share-unlock concerns raised in the day's coverage.

Trading Takeaway

SPCX's 9.69% advance on above-average volume reclaimed the $135 IPO offer price and closed near the top of the day's range, a constructive short-term signal set against a backdrop of mixed commentary — bullish on AI/compute-leasing revenue, cautious on valuation (39x forward price-to-sales) and the August 21 insider unlock. Next session's key levels to watch: resistance at $149.60/$150.00, support at $134.01/$133.29 and the $135.00 IPO offer price.
