Jest `toMatchObject` + any matcher not working as expected

I am trying to use expect.toMatchObject to test an object where some of the properties are variable. As far as I can tell from the docs this should work, but something is going wrong.

it('should create user new user', async () => {
  expect({
    username: 'giodamelio',
    password: 'hunter2',
    id: 10,
    createdAt: Date.now(),
    updatedAt: Date.now(),
  }).toMatchObject({
    id: expect.any(Number),
    username: 'giodamelio',
    password: 'hunter2',
    createdAt: expect.any(Date),
    updatedAt: expect.any(Date),
  });
});

When I run that I get this error.

 FAIL  test/models/user.test.js
  ● should create user new user

    expect(received).toMatchObject(expected)

    Expected value to match object:
      {"createdAt": Any<Date>, "id": Any<Number>, "password": "hunter2", "updatedAt": Any<Date>, "username": "giodamelio"}
    Received:
      {"createdAt": 1499463578254, "id": 10, "password": "hunter2", "updatedAt": 1499463578254, "username": "giodamelio"}
    Difference:
    - Expected
    + Received

     Object {
    -  "createdAt": Any<Date>,
    -  "id": Any<Number>,
    +  "createdAt": 1499463578254,
    +  "id": 10,
       "password": "hunter2",
    -  "updatedAt": Any<Date>,
    +  "updatedAt": 1499463578254,
       "username": "giodamelio",
     }
