SpaceX (NASDAQ: SPCX) released Grok 4.6 on Wednesday, achieving a score of 61 on the Artificial Analysis Intelligence Index. This performance matches OpenAI's GPT-5.6 Sol Max and trails only Anthropic's leading models, according to independent benchmarking firm Artificial Analysis.

The pricing structure for Grok 4.6 is significantly lower than its primary competitor. Grok charges $2 per million input tokens and $6 per million output tokens. In comparison, Sol Max costs $5 for input and $30 for output. This cost differential positions the model to shift the competitive dynamic from pure intelligence benchmarks to price efficiency.

Performance Gains

Grok 4.6 gained five points over Grok 4.5 in little more than a month. It represents a 23-point improvement over Grok 4.3. Artificial Analysis noted that the release returns SpaceX's AI unit to the frontier, with particularly strong performance on agentic work rather than static reasoning.

Anthropic remains the overall leader in the index. Polymarket now assigns xAI a 9% chance of having the best AI model by the end of the year, up from around 3% before the latest release. The market resolves using Arena's leaderboard rather than the Artificial Analysis index. Anthropic holds a 67% probability, while Google has fallen to fourth place behind xAI for the first time this year, with 6%.

Competitive Landscape

Grok's acceleration coincides with challenges faced by rivals. Reuters reported that Alphabet co-founder Sergey Brin has urged key AI staff to focus entirely on Gemini. Gemini briefly reached the frontier last November but subsequently slipped behind. Google delayed its next flagship model by two months following weak internal coding results. Compute shortages, internal disputes, and bureaucracy have also slowed progress.

Investor Implications

Morgan Stanley stated this week that investors may be undervaluing SpaceX's AI business. The bank indicated that further signs of Grok gaining traction through Cursor could help close the valuation gap. Morgan Stanley set its bull case for SpaceX shares at $600. Grok 4.6 is now available through Cursor and SpaceX's API.

What the Numbers Show

The pricing disparity between Grok 4.6 and Sol Max is substantial across both input and output metrics. While both models achieve identical scores of 61 on the Artificial Analysis Intelligence Index, Grok's output token cost ($6) is one-fifth of Sol Max's ($30). This suggests a potential margin advantage for users relying heavily on generative output, where costs typically exceed input expenses in agentic workflows.

Space Exploration Technologies Corp. (NASDAQ: SPCX) faces regulatory scrutiny in Texas after the state temporarily froze disbursements from its Broadband Equity Access and Deployment (BEAD) program. The hold, which took effect on Monday, remains in place until further notice as lawmakers investigate allegations that recent changes to the award process favored low-Earth-orbit satellite providers, including SpaceX’s Starlink service.

Regulatory Scrutiny Intensifies

The Texas Broadband Development Office notified subgrantees that no further action was required at this time, citing an ongoing legislative review. The pause follows testimony from Broadband Development Office Director Bryant Clayton, who informed lawmakers that Governor Greg Abbott’s office had requested a review of the payment structure for low-Earth-orbit providers shortly before awards were finalized. This request preceded a change in the disbursement schedule.

Legislative leaders have escalated the oversight measures:

• Lieutenant Governor Dan Patrick and House Speaker Dustin Burrows requested a performance audit by the State Auditor’s Office, demanding a full accounting of public funds.
• Comptroller Don Huffines launched a separate internal review.
• Republican State Senator Charles Schwertner stated the oversight committee would monitor the office for fairness and transparency.

Democratic State Senator Nathan Johnson alleged the process may involve "coordinated corruption," though he noted he was not drawing final conclusions. Both Starlink and Amazon.com Inc.’s (NASDAQ: AMZN) satellite broadband business were selected as Texas BEAD subgrantees, although the state has not publicly disclosed the specific amounts awarded to each entity.

What the Numbers Show

The controversy emerges against a backdrop of rapid expansion for SpaceX’s connectivity division. According to the company’s first public quarterly report, Starlink subscribers doubled to 12 million by the end of June. During this period, connectivity revenue rose 66% to $4.29 billion, while operating profit reached approximately $1.7 billion. This growth trajectory coincides with geographic expansion, including the launch of orders in Vietnam, marking the sixth Southeast Asian market for the service.

Despite the operational growth, market sentiment reflects uncertainty. Benzinga edge rankings indicate a negative price trend for SpaceX stock across short, medium, and long-term horizons. As of Wednesday overnight trading, SPCX shares were up 0.38% at $146.70. Benziga reached out to SpaceX for comment but did not receive an immediate response.
