Could MSFT reach $700, and could 2027 become a banner year for the stock market?
Recently, market chatter has emerged suggesting that Microsoft (MSFT) could trade near $700 per share by the end of 2027. The speculation appears to have gained traction after reports that Michael Burry bought long-dated Microsoft call options with strike prices in the low $700s, alongside broader talk that 2027 could be a strong year for the company, I don’t really like these kinds of speculative bets, but I can still see why people would make that argument.
At today’s MSFT price around $390, a $700 target means about +79% upside and roughly $5.21T market cap using about 7.445B diluted shares.
Before understanding what the main driver behind MSFT really is, we need to recognize that most of the bull case comes from Azure’s growth, plus Microsoft’s exposure to OpenAI and Anthropic.
There is a clear market example with EchoStar and SpaceX: EchoStar was roughly a $20 stock, but its small SpaceX-related stake helped push the stock toward $100.
MSFT owns approximately 27% of OpenAI on an “as-converted” basis. Microsoft’s latest 10-Q says it has “an investment of approximately 27 percent of OpenAI on an as-converted basis,” accounted for under the equity method. It also says Microsoft committed $13B total and had funded $11.8B as of March 31, 2026.And if we use the similar way, we can obtain:
| Date / Period | OpenAI valuation | Change from previous | Implied MSFT stake value at 27% | Extra value per MSFT share |
|---|---|---|---|---|
| Jan 2023 | ~$29B | — | ~$7.8B | -$17.1/share |
| Feb 2024 | $80B+ | +176% | $21.6B+ | -$15.2/share |
| Oct 2024 | $157B | +96% | $42.4B | -$12.4/share |
| July 2025 area | ~$300B | +91% | $81.0B | -$7.3/share |
| Oct 2025 | ~$500B | +67% | $135.0B | $0/share |
| Mar 2026 | ~$852B | +70% | $230.0B | +$12.8/share |
| Bull case | $1.2T | +41% | $324.0B | +$25.4/share |
| Bull case | $1.5T | +76% | $405.0B | +$36.3/share |
| Extreme bull case | $2.0T | +135% | $540.0B | +$54.4/share |
The first MSFT bull-case chain is:
OpenAI IPO or valuation moves higher → the market takes it as proof that AI demand is real → investors believe Azure is one of the key infrastructure winners + MSFT hold a lot of OpenAI’s stock→ Azure growth estimates move higher → MSFT revenue and EPS estimates move higher ,MSFT deserves a higher multiple → MSFT stock rises.
Now we can talk about Anthropic. Microsoft is also investing heavily in Anthropic, but the structure is different from OpenAI.
At the Nov. 18, 2025, Microsoft/Nvidia/Anthropic deal, Microsoft’s announcement did not clearly disclose Anthropic’s valuation. Microsoft said it would invest up to $5B, Nvidia up to $10B, and Anthropic would purchase $30B of Azure compute capacity.
Based only on simple ownership math, Microsoft’s potential equity stake does not look huge:
$183B valuation → about 2.7%
$350B valuation → about 1.4%
$380B valuation → about 1.3%
$965B valuation → about 0.5%
For Anthropic, the more important bull case is the circular financing / circular demand structure:
Microsoft invests in Anthropic → Anthropic uses that funding to buy Azure compute → Azure demand and backlog look stronger → Microsoft’s AI cloud revenue visibility improves → Anthropic looks stronger because it has both funding and compute access → Anthropic’s valuation can move higher → the market becomes more confident in Microsoft’s AI infrastructure story.
If we plug the $700 MSFT target into the valuation table, it actually does not look as crazy as it first sounds.
| Scenario | Price | Implied market cap | P/E on FY2027 EPS $19.45 | P/E on FY2028 EPS ~$23.32 | P/E on FY2029 EPS ~$27.90 |
|---|---|---|---|---|---|
| July 2025 $4T MSFT | ~$537 | ~$4.0T | ~27.6× | ~23.0× | ~19.2× |
| $700 target by 2027/12/31 | $700 | ~$5.2T | ~36.0× | ~30.0× | ~25.1× |
| $700 target by 2028/12/31 | $700 | ~$5.2T | less relevant | ~30.0× | ~25.1× |
So in some ways, Michael Burry’s $700 MSFT call options are conservative. some traders are more aggressive. This is not investment advice, and I do not hold MSFT. But is everything really as good as the market expects?
